Frequently Asked Questions - 351R CAMBRIDGE

How do I connect my speakers to the Cambridge 351R?

Connect the speakers to the corresponding speaker terminals on the back panel. Ensure correct polarity: red to positive, black to negative. For impedance, use speakers rated 4-8 ohms.

Why is there no sound coming from my receiver?

Check that the receiver is powered on and the correct input source is selected. Verify speaker wires are properly connected and that the speakers are not set to 'off' in the speaker setup menu. Also ensure the volume is not muted or too low.

How do I set up the FM tuner?

Connect the included FM antenna to the FM antenna input. Press the TUNER button on the remote or front panel. Use the TUNING buttons to search for stations. To store a station, press and hold the MEMORY button.

My remote control isn't working. What should I do?

First, check the batteries and replace them if needed. Make sure there are no obstacles between the remote and the receiver's IR sensor. If the problem persists, try resetting the remote by removing the batteries and pressing all buttons for 5 seconds.

Can I use the receiver with a 4K TV?

Yes, the Cambridge 351R supports 4K video pass-through via HDMI. Connect your 4K source to one of the HDMI inputs and your TV to the HDMI output. Ensure your HDMI cables are high-speed.

How do I perform a factory reset on the 351R?

Turn off the receiver. Press and hold the POWER button and the INPUT button simultaneously until the display shows 'CLEAR'. Release the buttons. The receiver will reset to factory defaults.

What should I do if the receiver overheats?

Introduction Before connecting

Thank you for purchasing this 351R AV Receiver. We are confident that you will enjoy many years of listening pleasure from it. Like all Cambridge Audio products the 351R adheres to our three core principles – stunning performance, ease of use and incredible value.

As such, the five audiophile grade amplifiers are kept as separate as possible from the processing and input stages and feature a large power supply with a low flux toroidal transformer.

This careful design of the amplifier stages ensure that the 351R can reproduce the dynamics and scale required for modern movie soundtracks whilst also being able to reproduce a genuinely musical performance with either stereo or multichannel music sources.

A full range of HDMI, digital and analogue inputs are fitted. These allows the connection of suitably equipped Blu-ray players, DVD players, satellite/set-top boxes and game consoles for decoding into stereo, stereo + sub or various digital surround formats.

The latest formats are supported including Dolby True HD, Dolby Digital Plus, DTS-HD Master Audio and DTS-HD High Resolution Audio in their 5.1 variants. In particular, support for the true lossless Dolby True HD and DTS-HD Master Audio formats provides unprecedented audio fidelity from Blu-ray discs.

Various HDMI 1.4 features are supported including 3D TV and deep-colour pass-through from suitable sources.

An Audio Return channel is also featured that allows audio to be passed back from a Smart TV to the 351R via the HDMI output.

The 351R is also capable of decoding encoded analogue or digital stereo sources in Dolby Pro Logic® II or DTS Neo:6 for a convincing and effective 5.1 surround experience from a matrix encoded stereo source.

Conventional analogue stereo inputs allow the connection of audiophile CD players and the like, and an Analogue Stereo Direct mode with no processing ensures the very best possible stereo reproduction for these.

An RS232 port and IR Emitter In also make it easy to integrate the 351R into a Custom Install situation.

All this proprietary engineering is housed within our low resonance, acoustically damped chassis.

Remember your 351R can only be as good as the system it is connected to. Please do not compromise on your source equipment, speaker package or video and audio cabling. Naturally we particularly recommend our Blu-ray players, digital and analogue iPod docks, Network and CD players from the Cambridge Audio Azur range, which have been designed to the same exacting standards as our receivers. Your dealer can also supply excellent quality Cambridge Audio interconnects to ensure your system realises its full potential.

Thanks for taking the time to read this manual, we do recommend you keep it for future reference.

Matthew Bramble

Cambridge Audio Technical Director

and the 351R design team

The process of setting up the 351R is first to make all the connections to your speakers and source equipment and then set the unit up via its On-Screen Display (OSD) as there are various settings and adjustments that need to be made before the 351R can be used.

However before you actually decide which connections to make or perform any adjustments it is strongly advised that you read through the '351R setup' section of this manual first, starting on page 12.

A lot of explanation is included that will help you to choose the right connection types for both your sources and TV.

Plug fitting instructions (UK only)

The cord supplied with this appliance is factory-fitted with a UK mains plug fitted with a 5-amp fuse inside. If it is necessary to change the fuse, it is important that a 5-amp fuse is used. If the plug needs to be changed because it is not suitable for your socket, or becomes damaged, it should be cut off and an appropriate plug fitted following the wiring instructions below. The plug must then be disposed of safely, as insertion into a mains socket is likely to cause an electrical hazard. Should it be necessary to fit a 3-pin BS mains plug to the power cord, the wires should be fitted as shown in this diagram. The colours of the wires in the mains lead of this appliance may not correspond with the coloured markings identifying the terminals in your plug. Connect them as follows:

The wire which is coloured BLUE must be connected to the terminal which is marked with the letter 'N' or coloured BLACK.

The wire which is coloured BROWN must be connected to the terminal which is marked with the letter 'L' or coloured RED.

The wire which is coloured GREEN/YELLOW must be connected to the terminal which is marked with the letter 'E' or coloured GREEN.

If a standard 13-amp (BS 1363) plug is used, a 5-amp fuse must be fitted or, if any other type of plug is used, a 5-amp fuse must be fitted, either in the plug or adaptor, or on the distribution board.

Aerial connections

FM aerial

Connect an aerial to the FM 75 ohm socket (a simple wire aerial is supplied only for temporary use). Extend the lead and move the aerial around until you get the best reception. For continued use, we strongly recommended using a 75ohm outdoor FM aerial.

To avoid damaging the speakers with a sudden high-level signal, be sure to switch the power off before connecting the speakers. Check the impedance of your speakers. Speakers with an impedance of 8 ohms (each) are recommended.

The coloured speaker terminals are positive (+) and the black speaker terminals are negative (-). Make sure correct polarity is maintained at each speaker connector or the sound can become weak and "phasey" with little bass.

Prepare the speaker cords for connection by stripping off approximately 10mm (3/8") or less (no more than 10mm, as this could cause a short-circuit) of the outer insulation. Twist the wire tightly together so there are no loose ends. Unscrew the speaker terminal knob, insert the speaker cable, tighten the knob and secure the cable.

Note: All connections are made via loudspeaker cable, except if using an active subwoofer which would be connected via a standard RCA phono cable. Banana Plugs (4mm standard) connected to the speaker cable are recommended for direct insertion into the speaker terminals.

Please refer to the 'Speaker Configuration' section of this manual for more information on 5.1 speaker setups.

● Cambridge Audio

Analogue audio connections

Note: Do not plug in the mains power lead or turn the unit on until all connections have been made.

Connect to source equipment using stereo phono/RCA cables (stereo 2RCA-2RCA). Tape/MD/CDR recorder/players require two sets of stereo phono/RCA cables, one for recording, one for listening.

Digital audio connections

Two types of digital audio connections can be made to the 351R:

① Optical (Toslink)
② Coaxial (S/P DIF)

See later section on how to assign the digital inputs to specific sources.

HDMI input connections

HDMI (High-Definition Multi-Media Interface) is an all digital connection that can carry both audio and video in one cable. Direct digital transfer of audio and video and support for various types of High Definition video content and high resolution audio make this the best connection type to use.

Video output connection (HDMI)

Connection to the TV is by HDMI.

● Cambridge Audio

351R setup

1. Speaker configuration

First tell the unit what kind of speaker package you have. The 351R can support up to a 5.1 speaker setup which means 5 speakers (Front Left, Front Right, Centre, Surround Left, Surround Right,) plus a mains powered Subwoofer (the .1).

Refer to the diagram above for a typical example of a 5.1 loudspeaker setup. Always adjust the speakers and listening positions until you are happy with the sound. Please refer to your loudspeaker and subwoofer manuals for more detailed positioning information.

1. Front Left and Right speakers

For stereo and multi-channel sound.

2. Centre speaker

For dialogue and centre sounds. Ideally position at a similar height to the front left and right speakers (above or below the TV/monitor). Using a centre speaker from the same manufacturer/range as used for the front left and right speakers is advisable. This "timbre matching" allows surround effects to flow more naturally from left to right without obvious transitions between the speakers.

3 Surround Left and Right speakers

For ambient and multi-channel sound. Floorstanding speakers should be angled towards the listening position. Bookshelf/standmount speakers should be wall mounted or used with dedicated speaker stands, positioned at or above ear height.

4 Subwoofer

For improving the bass in your system, as well as reproducing dedicated LFE (Low Frequency Effects) cinema effects when playing Dolby Digital or DTS encoded discs. Your subwoofer can often be placed almost anywhere in the room as bass is less directional, but experimentation with positioning is recommended.

In each case the 5.1 in fact relates to the maximum number of speakers that can be used, as the Centre, Sub and Surround speakers can all be deleted if required (although of course performance is reduced). For example, if you choose not to use a Centre Channel speaker you can set this to 'None' in the settings, as shown later and the 351R will automatically redirect the centre channel audio information into the Left and Right Front channels, creating what is known as a 'Phantom Centre'.

Similarly, you might decide not to use a subwoofer if your main Left and Right speakers are capable of reproducing enough bass for a satisfying music/movie experience. The 351R will then automatically re-direct the bass from the Subwoofer/Low Frequency Effect channel to the Left and Right Front Speakers.

Note: This setup is very important as the 351R will also automatically use this information to select appropriate Dolby and DTS decoding modes dependant not only on the source material but also the speaker package it knows you have.

To tell the unit the type of package you have, turn on the On-Screen Display via the remote button as shown. Highlight the 'Speaker Config.' menu by using volume ▲ and ▼ on the remote then go to it by pressing Enter:

Now move down and by highlighting each speaker in turn and using the Left and Right arrows select from 'Large' or 'Small' for each speaker. 'Large' or 'Small' are used to describe each speaker in terms of bass response, they do not necessarily reflect the actual physical size of the speaker.

Large = Speakers with an extended low frequency response of approximately 20-40Hz to 16-20kHz (floorstanders or high quality larger stand-mounted speakers).

Small = Speakers with a less extended low frequency response of approximately 80-100Hz to 16-20kHz (small stand-mounted, bookshelf or satellite speakers).

Setting each speaker allows the 351R to perform what is called Bass Management and to direct low frequency bass from music and the Low Frequency Effects channel of surround sound material to those speakers best able to reproduce it. If you do not wish to use any of the speakers set its setting to 'None'.

The Subwoofer output can also be set to On or Off. If no sub is being used, make sure this setting is set to Off to allow the 351R to re-direct the bass information in this channel to other speakers.

Note: The 351R will force some speakers to certain settings in the following circumstances!

The Front Left and Right speakers may be 'Large' or 'Small' but not 'No' as they are always required for any type of music/movie reproduction.

Bass must always be reproduced by either the Front Left and Right or Subwoofer channel (or both). Setting the Front Left and Right to 'Small' will result in the Subwoofer automatically being set to 'Yes'. Setting the Subwoofer to 'No' will automatically result in the Front Left and Right being set to 'Large'.

If the Front Left and Right cannot reproduce low frequency bass a Subwoofer must be used. i.e. If the Front Left and Right are set as 'Small' the Sub must be Set to 'Yes'.

Also, setting the Front Left and Right as 'Small' will always set the other speakers as 'Small' (and the Sub to 'Yes'). This is because LFE/ bass information should not be redirected to the surround channels.

To store the setting simply come back out of the OSD (pressing the 1/0 button always moves back one menu item, and then exits and stores from the main menu screen).

2. Speaker setup

The following two sections can be performed by Cambridge Audio CAMCAS procedure so you can if you wish jump straight to that section. However, it is recommended that you do read these sections to understand the reasons for these settings and their implications.

Speaker Delay

Because the speakers in a surround sound system are usually different distances from the listener the 351R incorporates the ability to apply a variable digital delay to each of the channels so that the sound from each arrives at the same time at the listening position for best surround-sound effect.

    A --> F[" "]
    G["6"] --> H[" "]
    H --> I[" "]

1 = Front Left speaker
2 = Front Right speaker
3 = Centre speaker
4 = Surround Left speaker
5 = Surround Right speaker
6 = Subwoofer (can be placed almost anywhere)

To set the delay times automatically, refer to the "Auto setup" section of this manual.

To set the delay times manually, simply measure the distances from the listening position to each speaker as shown in the following diagram:

No delay setting for the subwoofer is necessary.

Set the distances in the OSD Speaker Distance menu to the nearest value in metres or feet (1 foot = 0.3 metres). The speed of sound is approx 340 metres per second, the 351R thus introduces approx 3mS of delay per meter of distance set.

Go to the 'Speaker Distance' and highlight each speaker in turn. Set the distance to the nearest value to that which you measured by using the Left and Right arrows (the values do not need to be exact):

Press the 1/0 button to exit the menu.

Level calibration

The 351R allows level calibration to match the acoustic level between different types/sizes or even manufacturers of speaker that may be being used for each channel. This is achieved by adjusting the relative level of each speaker. This can be done manually through the 'Level Calibration' menu in the OSD or automatically, see the following Auto setup section of this manual.

The basic process for manual adjustment is to listen to or measure with a Sound Pressure Level (SPL) meter (more accurate and recommended but not essential) the level of sound produced by each speaker and set relative levels for each speaker so that they all sound the same loudness at the normal listening position. The 351R incorporates a Test Signal Generator (broadband white noise) to facilitate this.

Press the 1/0 button on the remote control to turn on the OSD then select the 'Speaker Level' menu. Now turn on the test signal by highlighting this item and pressing the Left or Right arrows:

Audio In. Select	Test Signal	Off <>
Tone/Sub Config.	Front L	0dB <>
Speaker Config.	Front R	0dB <>
Speaker Diatanca	Surr. L	0dB <>
Speaker Level	Surr. R	0dB <>
Speaker Xover	Center	0dB <>
Auto Setup	Subwoofer	0dB <>
Dolby/DTS setup
OSD Setup

You can now move up and down the channels using Volume ▲/▼ on the remote. Each time a new channel is selected the test signal will be heard to move to that channel. Compare the loudness of all channels as heard at the listening position.

A "rushing" or "hissy" sound should be heard.

Now adjust the channels so they all sound the same (in terms of loudness only, channels of different frequency responses can sound different in terms of the "tone" of the sound i.e. more or less hissy).

Pick the channel that sounds most different and select it to listen to the test signal. Now adjust the relative level in dB (using the ◀/▶ buttons on the remote) and continue comparing it to other channels until it is of equal loudness. The level can be adjusted up to + or - 10dB in 1dB steps. Repeat the process with the next most different channel. Once all channels sound the same in terms of loudness, press the OSD button again to save the settings and exit the menu.

CAMCAS Auto speaker setup for Distance/Level

The 351R includes our simple automatic speaker setup system called 'CAMCAS' (Cambridge Audio Mic Controlled Auto Setup). The system performs two sets of tests firstly checking which speakers are connected and whether they are wired correctly and in phase then a second automatically measuring and adjusting the speaker delay timings (i.e. distance setting) and levels.

Before activating this feature the 'Decode Mode' (i.e. type of speaker package e.g. 5.1) and Large/Small/None status of each speaker must be set correctly as per section 1. This is important as the unit will only look for and check the speakers you have told it you have.

● Cambridge Audio

To perform the Auto Setup function, first connect the supplied microphone to the front panel 'Mic In' input and place it at your normal listening position in the room. It should also be placed at normal listening height.

Press the I/O button on the remote control to access the OSD and then select the Auto Setup Menu. This will access the "Auto Setup Menu" as below.

Audio In. Select tone/sub config.Speaker Config.Speaker DistanceSpeaker LevelSpeaker Xover	Please press ENTER to start auto setup

Follow the on-screen instructions and press 'Enter' on the remote control when ready to start the Auto Setup function.

Auto Setup Menu

Plug the microphone into the Mic. input on the front panel and place the microphone at normal listening position and height

Once activated the OSD will display the message below and the word 'AUTOSETUP' will also be displayed on the front panel of the 351R to confirm.

Auto Setup Menu

The unit is now checking which speakers are connected and their phase

Please wait...

A series of test signals will now be output from all of the connected speaker terminals of the 351R (including the Subwoofer output).

Once finished the unit will display a screen similar to the one below reporting which speakers were found and any that appear out of phase.

arur JS1R

The speakers that have been found are:

L C R SL SR LA RA SW

All speakers are in phase

If any speakers appear unconnected or out of phase carefully check the connections on the speaker and the back of the unit. Also check any bi-wiring links that might be present on the speaker. For any out of phase speakers check that the relevant + terminal of the 351R goes to the + terminal of that speaker and similarly the - terminal of the 351R goes to the - terminal of the speaker for that channel.

If necessary press the button to perform a retest or press Enter to start the second part of the auto setup procedure as below.

Auto Setup Menu

The unit is now measuring the Distance and Level settings for your speakers

Please wait......

Again a series of test signals will now be output from all of the connected speaker terminals and subwoofer. The 351R uses these to measure the levels and distances (and hence introduce the correct delays) appropriate to your speakers and room characteristics.

When the auto setup of the 351R is completed successfully, the 351R will return to the Speaker Setup Menu.

Audio In, SelectTons/Sub Config.Speaker Config.Speaker DistanceSpeaker LavalSpeaker Xover	Please press ENTER to start autosetup
Auto Setup
Dolby/DSS SetupOSD Setup

The Speaker Distance and Level Calibration settings for each speaker will have been updated.

It is of course now possible to go into the Speaker Delay and Level Calibration menus if you want to manually check/adjust the settings made by the CAMCAS system, and it is always advisable to check them as no system can be totally foolproof.

To exit the auto setup menu of the 351R continue to press the button on the remote control to exit all menus or until 'OSD' is no longer displayed on the front panel. You can now unplug the microphone and put it away for future use.

Note: If the auto setup of the 351R is unsuccessful for some reason a 'Fail' message will appear on the OSD. Included in this message will be details of the speaker channel or channels which have not been successfully adjusted. If this is the case, please again check that the speaker or speakers detailed in the OSD as 'failed' are connected correctly & have not been wired out of phase. Also check the microphone connection and any other external issues that could have affected the tests such as noise in the room etc.

Note: Like all such systems CAMCAS has some limitations. Speakers that exhibit very strong phase angles or deliberately wire some drive units out of phase can of course appear to the system as an out of phase speaker when correctly connected. If a speaker is reported as out of phase but is correctly wired please consult the speakers manufacturer in case this is the case.

Similarly bi-polar speakers which radiate in more than one direction can make it difficult to measure the distance and sometimes level accurately as you might expect.

In all cases it is always advisable to manually check the settings CAMCAS has made for a 'reality check' to ensure there are no obvious errors.

3. Source setup

The next step is to select each source input in turn on the 351R and tell the unit:

• The type of audio connection you want to use for that source (Analogue, Digital or HDMI).
• The processing mode for that source.

The 351R remembers these settings individually for every source input and automatically recalls them as and when you change source input.

Select the 'Audio In. Select' menu. Highlight each source in turn and select either analogue, digital or HDMI input types (use the ◀ and ▶ arrows):

Each source always has a dedicated HDMI input and a dedicated pair of Analogue Stereo sockets associated with it on the back panel.

Audio In. Select	BD/DVD	HDMI <>
Tone/Sub Config.	CD	HDMI <>
Speaker Config.	Video	Analog <>
Speaker Distance	Aux	Analog <>
Speaker Level
Speaker Xover	HDMI TV ARC	Enabled <>
Auto Setup
Dolby/DTS Setup
QSD Setup

quit : [I/O] Enter : [ENTER]

In addition, there are two S/P DIF (Co-Axial) and one toslink (Optical) digital inputs available that can be freely assigned to any source.

For each source, pressing the Audio Input Type button thus scrolls through the following options: HDMI, Analogue, Co-Ax1, Co-Ax2 and Opt.

HDMI and Analogue refer to the dedicated sockets for that source, Co-Ax1, Co-Ax2 and Opt refer to the three assignable sockets that any source can select.

These digital inputs should only be selected (assigned) to one source each.

Analogue inputs will require a stereo phono/RCA to phono/RCA cable connection to the 351R. Digital inputs will require either a 75ohm digital type phono/RCA to phono/RCA co-axial cable (S/P DIF) or an optical fibre cable (TOSLINK).

Note: HDMI TV ARC is covered in a later section of this manual.

Once you have set the audio types exit the OSD to save.

This setting can also be changed at any time without using the OSD by pressing the Audio Input Type button on the front panel or remote, this will then cycle between analogue, digital or HDMI input types where available for the currently selected source, as usual they will then be remembered the next time you return to that source.

Surround sound modes

The 351R supports several music and home-cinema listening modes. The output the 351R can provide, depends both on the source signal present, the speaker setup selected and the decode mode selected. Before we describe how to operate the 351R, below is a brief guide to the Surround Sound formats that the 351R is compatible with for reference:

DOLBY TRUEHD

Dolby's lossless audio technology developed primarily for high capacity Blu-ray discs/players. Dolby True HD delivers theoretically bit-for-bit sound identical to the studio master by the use of 100% lossless encoding. Previous formats such as Dolby Digital 5.1 or EX have used lossy encoding where some data (that is theoretically less audible) is always lost in the encoding process to reduce the storage capacity needed on the disc. This is a new format that supports 5.1 full-range channels of 24-bit/96 kHz audio or two channels of 24/192 kHz via Blu-ray discs and is not backwards compatible with earlier schemes. The format can either be transmitted as a 'bitstream' to the 351R for internal decoding (recommended) or can be decoded by some Blu-ray players internally and sent to the 351R as multi-channel PCM. In both cases an HDMI connection is required to the 351R and a suitable Blu-ray player as Dolby True HD is only ever transmitted over HDMI.

DOLBY DIGITAL PLUS

An encoding scheme based on the original Dolby Digital CODEC, but with enhancements to improve coding efficiency and improved audio quality. These Dolby Digital Plus bitstreams are not backward compatible with legacy Dolby Digital decoders but require an AV Receiver developed to decode them (such as the 351R) and an HDMI connection as Dolby Digital Plus is currently only transmitted over HDMI. It is however a requirement that any Dolby Digital Plus enabled Blu-ray player must also be able transform the Dolby Digital Plus into a backwards compatible Dolby Digital 5.1 output for playback on legacy Dolby Digital systems. The 351R is however fully compatible with Dolby Digital Plus.

dts-HD Master Audio

A new lossless audio codec from DTS, rather than being incompatible with earlier versions, DTS-HD Master Audio is transmitted as an extension to a normal DTS bitstream. A second embedded stream is sent which contains the "difference" between the original studio master and the lossy compressed DTS. DTS-HD Master Audio enabled devices (such as the 351R) are able to use this difference information to recreate a bit for bit lossless version of the original data. Devices which do not support the Master Audio extension simply decode the original 5.1 DTS stream and ignore the Master Audio extension providing backwards compatibility.

dts-HD DTS-HD High Resolution Audio

Known also as DTS-HR an extension to the original DTS audio format. DTS-HD High Resolution Audio supports fully discrete channels compared to DTS's 5.1. As with DTS-HD Master Audio a second embedded stream is sent which contains the "difference" between the original studio master and the lossy compressed DTS, however in this case the extra stream is also formed by lossy compression.

DOLBY DIGITAL

Known also as DD (3/2) or DD 5.1, provides (up to) 5.1 output from suitable encoded Dolby Digital material, with 5 main channels (Front Left, Front Right, Centre, Surround Left, Surround Right) and a Low Frequency Effects Channel for the subwoofer, all discretely encoded. Decoding Dolby Digital requires a Dolby Digital encoded DVD disc and a digital connection from the source equipment (Such as a DVD player) to the 351R.

Note: Dolby Digital and DTS formats can sometimes carry less channels than their maximum such as Dolby Digital (2/0) which means a Dolby Digital encoded signal which is actually only carrying a two channel stereo signal (other channels inactive).

dts Digital Surround

Known also as DTS (3/2) or DTS 5.1, DTS provides (up to) 5.1 output from suitable encoded DTS material, with 5 main channels (Front Left, Front Right, Centre, Surround Left, Surround Right) and a Low Frequency Effects Channel for the subwoofer, all discretely encoded. Decoding DTS requires a suitably encoded DTS disc and a digital connection from the source equipment to the 351R.

● Cambridge Audio

Surround sound modes cont.

DOLBY

PRO LOGIC II

The replacement for the original ProLogic, Pro Logic II is a technology where 5 channels (Front Left, Front Right, Centre, Surround Left, Surround Right) are encoded into a Stereo mix by an analogue matrix process. Dolby Pro Logic II material can be played back by normal Stereo equipment (as Stereo) or decoded into 5 channel surround-sound.

Dolby Pro Logic II is compatible with the earlier 4 channel (Left, Centre, Right and mono Surround) Dolby Pro Logic system (which was the decoding counterpart to Dolby Surround encoding) as used widely on Video tapes, TV broadcasts and earlier films.

Note: Pro Logic does not include a Low Frequency Effects channel for the Subwoofer, but the 351R can create a Subwoofer output (for 5.1) via Bass management. Refer to the 'Tone/Sub/LFE configuration' section in the 'Operating instructions' part of this manual.

dts

A DTS technology which is able to recreate 5 or 6 channels (Left Front, Right Front, Centre, Left Surround, Right Surround plus optional Surround Back) surround sound from suitable analogue matrix encoded stereo source material. DTS Neo:6 material can be played back by normal Stereo equipment (as Stereo) or decoded into 5.1 as on the 351R by sending the Surround Back decode to the both the Surround Back Left and Right speakers.

Note: Neo:6 does not include a Low Frequency Effects channel for the Subwoofer, but the 351R can create a Subwoofer output via Bass management. Refer to the 'Tone/Sub/LFE configuration' section in the 'Operating instructions' part of this manual.

dts Digital Surround | 96/24

A DTS technology that provides 5.1 channels of 96kHz / 24bit audio (along with video if required) on DVD-Video and DVD-Audio (video zone) discs (when suitably encoded in DTS 96/24). DVD players which allow 'DTS digital out' pass the DTS 96/24 bitstream over S/P DIF or HDMI for decoding in the 351R.

DSP modes

These modes allow a surround-sound experience from source material that has no encoding at all. The surround sound effect is achieved by Digital Signal Processing of the Analogue or Digital stereo source used. Five modes are possible: Movie, Music, Room, Theatre and Hall.

Stereo/Stereo + Sub

Only the Front Left and Front Right speakers (and subwoofer if selected) have output in this mode. If an analogue source is selected it will be converted to digital via 24 bit A/D converters to allow digital domain sub creation and bass/treble controls.

If a digital source is selected the 351R will be processing either LPCM stereo (from the digital outputs of a CD player for instance) or a Stereo downmix of DD or DTS material (from the digital output of a DVD player for instance).

Other modes

Analogue Stereo Direct

Selects the analogue inputs for the current source directly with no A/D conversion, DSP processing, Bass/Treble or subwoofer channel active. Provides the very best fidelity for analogue hi-fi source equipment. In this mode the 351R is acting just like a normal hi-fi integrated amplifier.

Multi Channel PCM

Some playback devices (in particular Blu-ray players) are able to decode some of the above formats themselves internally and then output the decoded audio as Multi Channel PCM to the 351R. In addition Blu-ray disks can support native unencoded Multi Channel PCM soundtracks on the disc itself. In either case if your player can output these over HDMI the 351R is able to receive them in Multi-Channel PCM mode.

Operating instructions

To activate the 351R, switch the Power button on the rear panel to On then press the Standby/On button on the front panel.

Selecting the source

1. Select the desired source by pushing the corresponding source button on the front panel or remote control.

1. If necessary, press the Audio Input Type button to select the input mode of the source equipment, either analogue, digital or HDMI (depending on the connection made on the rear panel). You may have already assigned this in the 'Audio In. Select Menu' in the OSD.

The digital, analogue or HDMI icons on the display show which is the currently selected input type.

Note: The 351R stores the input type for each source so that it is automatically recalled when that source is selected again.

Select an appropriate mode for the source material/type you are listening to by pressing the Stereo or Surround Modes button and cycling through sub-modes where available.

- Selects 2 channel Stereo operation for stereo material, pressing again selects Stereo + Sub mode.

This is a digitally processed mode that allows bass and treble controls, and sub generation if required. The input can be either analogue (in which case it will be turned into digital by 24 bit A/D conversion) or natively digital.

- Selects a range of digital surround modes for the appropriately digitally encoded material.

Some Surround Sound types (such as the Dolby True HD and DTS HD Master Audio) are available only from Blu-ray disc over HDMI.

Pressing the Surround Modes button will cause the 351R to lock onto the incoming bitstream and select the first available mode for the current bitstream type.

In some circumstances (see tables) pressing the button again will switch to an alternative decoding option.

Dolby Pro Logic and Neo:6 are both available in various guises to decode appropriately encoded soundtracks. Additionally DSP modes are available to process sources with no encoding at all. Due to the matrix encoding process none of these modes incorporate flags that tell the 351R the type of encoding used in the source material. Thus you must manually select these modes.

Pressing the Surround Modes button when the 351R has locked to a DD/DTS bitstream will present more options where possible including Post-Processed modes.

These are modes that allow extra processing to be applied after the main surround-sound decoding. For instance Dolby Digital (2/0) + Pro Logic II Music. Which adds a 5.1 ProLogic decode to a Stereo Dolby Digital decode to turn 2 channel stereo into 5.1.

In automatic tuning mode the unit scans to the next strong station. In manual tuning mode the user can step manually through the frequencies. In preset mode the unit cycles through the presets only.

Two FM modes are available, stereo and mono - Press the Stereo Mono button on the remote to alternate between Stereo mode and Mono mode. If the Display button is pressed, the RDS station names of FM stations will be displayed if available.

Storing stations

1. Tune in a station you wish to store as explained previously.
2. Press and hold the Mode/Store button (or use the Store button on the remote) for 5 seconds.
3. Use the Tuning+/- buttons to select a preset station number (1-15). The station number will be displayed on the screen.
4. Press the Mode/Store button (or use the Store button on the remote) to memorise the frequency.

Radio Data Systems (RDS)

RDS is a method for the transmission of additional information from local radio stations. RDS will only work if the local broadcasting stations have RDS transmission and the signal is strong enough.

Press the Info button on the remote and go through the displayed functions. There are functions for PS, PTY, CT and RT:

PS (Station Name) - current station name will be shown

PTY (Program Type) - current name type of the program will be shown

CT (Clock/Time) - current time from Radio Station will be displayed.

Note: Clock/Time will be only transmitted from local radio station once a minute. If the Clock - Time is not available the message "NO CT" will appear briefly on the display.

RT (Radiotext) - Some Text messages will be shown.

Lip sync

The 351R can if required apply a small delay to the audio playback to resynchronise it to any video playback which appears to be behind the audio in time.

This can sometimes happen if the video is slightly delayed by a player or TV performing a lot of video processing.

Pressing the Lip Sync button on the remote will bring up the current Lip Sync value on the 351Rs main display and allow adjustments in 10mS (10 thousandths of a second) increments.

Setting the Lip sync value to 0 causes Lip Sync delay to be turned off.

Note: The Lip sync value is stored and recalled separately for each source.

Audio Return Channel

The 351R supports an Audio Return Channel (ARC) function from TVs that also support this function (which must feature an HDMI1.4 input and have actually implemented the ARC feature, see your TVs manual).

ARC allows a TV to send audio back down its incoming HDMI lead to the 351Rs HDMI output socket.

This function allows the 351R to play back the audio from a TVs built-in terrestrial cable or satellite tuner whilst you watch it's picture.

To enable the use of ARC, press the OSD button on the remote and navigate to the 'Audio In. Select' menu, select the HDMI TV- ARC and use the ◀/▶ buttons to select the Enabled setting.

Using ARC

ARC can be started in one of two ways. If your TV supports it there may be a menu item to start ARC on your TV.

Your TV then sends commands to the 351R which cause it to start an ARC session and 'TV-ARC' will appear on the front panel display automatically.

Some TVs may also start an ARC session whenever you select the in-built tuner and stop when you select another source.

Note: On many TVs their CEC/HDMI Link (which is often renamed as Vieralink or AnyNet etc.) must be turned on for ARC to function

Alternatively you can start ARC by pressing the Aux/TV button twice on the 351R (as long as TV-ARC has been enabled in the 351Rs OSD as above).

The first press selects Aux/TV, the second selects ARC and 'TV-ARC' appears on the front panel display. The 351R will then send commands to the TV over HDMI to try to start an ARC session.

To finish ARC simply disengage it on your TV or press a different source button on the 351R.

Advanced setup

For most users the basic three stage setup process should be sufficient for normal use. However, the 351R also features many more advanced settings for users who wish to further customise the settings and operation to personal preference.

Sub crossovers and bass management

As covered in the '351R Setup' section the 351R performs bass management for any speaker that is set to 'Small' in the OSD. This means that bass for speakers that are unable to reproduce bass effectively is instead routed to the subwoofer.

OSD Setup

The crossover adjustments in the Speaker crossover menu are used to determine the point as which this transition is made. In other words they set the frequency below which bass is routed away from any 'Small' speakers and into the subwoofer channel. It should be understood that bass sent to the subwoofer by bass management is different to bass encoded into the surround-sound material as a dedicated Low Frequency Effects channel.

If the source material contains a separate LFE channel (i.e. DD or DTS material) this is always routed to the subwoofer (if it is On) and is not affected by the crossover setting. Some encoding types (Such as Dolby Dolby Pro Logic II and Neo:6) do not actually have a LFE channel.

The default setting for all bass management crossovers is 80Hz and is a good global starting point. If you do not wish to make any adjustments simply leave all crossovers at this default setting.

Note: These settings are actually only used for speakers that have been set to Small in the Speaker Configuration Menu.

For advanced users it is however possible to adjust the speaker crossovers used for any speakers set as 'Small' independently to allow for the fact that you may wish to direct bass away from front floorstanding speakers (and to the Subwoofer) at perhaps 50Hz but away from Surround Left and Rights at perhaps 100Hz. If you wish to make these adjustments it is best to consult your loudspeaker manufacturers documentation or contact your dealer to determine the frequency response of your system and where each speaker types bass response starts to tail off (often called the 3dB or 6dB roll off/cutoff point). This would be approximately the point the corresponding crossover should be set to.

Tone/Sub configuration

Select the 'Tone/Sub Config.' menu:

OSD Setup

quit : [I/O] Enter : [ENTER]

The Bass response can be adjusted +/- 10dB @ 100Hz (shelving). The Treble response can be adjusted +/-10dB @ 10kHz (shelving). The "Tone" icon will light up on the display if these controls are adjusted away from 0dB (flat). The subwoofer crossover point can also be adjusted from 40 to 150Hz in 10Hz steps and also to 200Hz.

The 351R incorporates a couple of advanced Bass Management features. The overall Sub Level for DD/DTS modes, Dolby Pro Logic II/Neo:6 modes and Stereo + Sub mode can be set to different levels. This can be useful if you prefer to have a high level of Sub operation whilst watching movies but a lower level for music playback. The three levels are simply adjusted by up to +/-5dB in the OSD. The second feature is that the way Bass Management is applied can be changed.

In normal operation (Bass Augment Off) if the Front speakers are set to 'Small' (in the 'Speaker Config' menu) their bass is re-directed by high-pass filtering the Fronts and sending that bass to the Sub channel (i.e. bass is removed from the Fronts and sent to the Sub). If they are set to 'Large' no filtering takes place and no bass is sent from them to the Sub channel.

However with the Bass Augment function On and the Front speakers set to 'Large', bass from the Front Left and Right is now sent to the Sub channel without any filtering of the Front Left and Right taking place (i.e. these channels remain full range). In other words, the bass in the Sub channel is augmented by extra bass from the Front Left and Right channels. If the Front Left and Right are set 'Small', Bass Augment has no effect and operation is the same as for Bass Augment Off.

Bass Augment can be On or Off separately for DD/DTS or Dolby Pro Logic II/Neo:6 operation.

There is no Bass Augment function for Stereo + Sub mode because in this mode if the Front speakers are set to 'Large' they will actually always be unfiltered.

Bass Augment can be a useful function with Dolby Pro Logic II and Neo:6 material because these encoding types do not include an LFE Channel. This would normally mean that if all the speakers in your setup were set to 'Large', the subwoofer would in fact be inactive (as no bass has been re-directed plus there is no LFE channel). If it is desired to have the subwoofer running with all Large Speakers and these encoding types, enable Bass Augment for Dolby Pro Logic II/Neo6 and then set the Crossover points and levels by ear. A Sub channel will now be created from the Front Left and Right channels without filtering them. As with all adjustments it is a good idea to experiment to determine what works best with your particular setup.

Note: These adjustments work in all digitally processed Stereo or Surround modes but not in Analogue Stereo Direct mode.

The LFE channel (for DD / DTS material) can also be trimmed by up to 10dB in 1dB steps useful for late night listening or other situations where it might be desired to reduce the low frequency effect level perhaps temporarily.

Remember the LFE is the Low Frequency Effects channel encoded into the disc and is different to the over all sub level which can include bass management from the other speakers.

Bass and Treble adjustments can also be made from the remote handset without entering the OSD by pressing the Bass/Treble button on the remote and then using the volume up and down buttons.

The first three adjustments affect Dolby Pro Logic II processing (or post-processing) in Music mode only. Movie and Game modes where available are preset as part of their specification to match the encoding or provide a specific effect. These adjustments have no affect in these modes.

1. Panorama mode

A Dolby Pro Logic II mode that extends the front Stereo image to the surround sound speakers for a more enveloping experience. This mode can be either On or Off.

2. Centre Width

Allows gradual adjustment of the centre image from being produced only by the Centre speaker (Setting 0) through levels of being spread between the centre channel and Left and Right speakers to finally being produced by the Front Left and Right speakers only (Phantom Centre, Setting 7). Useful in optimising the Front/Centre/Right soundfield for best integration of the 3 speakers. Best tuned by ear.

3. Dimension

Adjusts the soundfield to be gradually shifted from the front of the room to the back to suit taste, speaker positioning and size of room. Setting 0 has the image furthest forward, 6 furthest back.

All three adjustments are a matter of personal preference, experiment for the settings that you prefer when you are using Dolby Pro Logic II decoding.

4. Dynamic range control

This setting controls the dynamic range of Dolby Digital movie soundtracks by compressing the audio to limit the difference in level between loud and quiet passages in the movie.

This can be a useful feature when watching movies late at night for instance. Three settings are possible:

Auto - Compression is always applied for Dolby Digital and Dolby Digital Plus soundtracks. The application and amount of compression to Dolby True HD soundtracks is dictated by the soundtrack itself.

Off - No Compression (normal full dynamic range playback)

On - Compression is always applied for all Dolby soundtracks (reduced dynamic range playback)

Custom installation (C.I.) use

An RS232 port is featured which allows the 351R to be controlled by C.I. systems.

A full code table and RS232 protocol for this product is available on the Cambridge Audio website at www.cambridge-audio.com.

Reset/Back-up memory

The 351R has a function that preserves the preset memory and other settings. In the event of a power failure, or if the power cord of the unit is disconnected from the mains outlet, the back-up memory will preserve the preset memory for approximately one week. If the power supply is interrupted for 7 days or longer, the memory settings will be erased.

If it is desired to reset all settings to their factory defaults (or in the unlikely event that the unit locks up due to an electrical discharge etc), with the unit on and out of Standby mode, press and hold the FM Tuner and Analogue Stereo Direct buttons on the front panel for three seconds.

"RESET" will appear briefly on the front panel display before returning to Standby mode.
