... and congratulations for buying the Arcam Logo sub-bass loudspeaker system.
Logo can extend the bandwidth of your main (satellite) speakers by accurately revealing the low frequency components of stereo and surround sound programme sources. It also offers a separate but concurrent LFE (low frequency effects) connection – this is a channel intended by the recording engineer to be exclusively reproduced by a subwoofer. Logo's own volume control permits the level to be adjusted independently to achieve a perfect balance in the listening room.
Logo features its own 200W amplifier which is close-coupled to a downward-facing long excursion driver that takes full advantage of the latest materials technology and a sophisticated braced cabinet design. The bass response is actively corrected by a Linkwitz transform crossover circuit to give a Bessel alignment: this minimizes time distortion for accurate bass transients. The result is a performance of great power and musicality.
Please take a moment to read this handbook, as the advice that it contains will help you get the maximum benefit from your purchase.

Arcam Logo sub-bass system
IEC mains power lead
this I handbook!
thank you...
Positioning the unit
Place the Logo speaker unit on a level, firm surface, avoiding direct sunlight and sources of heat or damp.
Do not place Logo in an enclosed space such as a bookcase or closed cabinet unless there is good provision for ventilation. The Logo speaker unit is designed to run warm during normal operation.
Do not place your record deck on top of Logo. Record decks are very sensitive to the noise generated by mains power supplies which will be heard as a background 'hum' if the record deck is too close. Vibrations from Logo may also cause the pickup stylus to jump tracks.
Power
Logo is supplied with a moulded mains plug already fitted to the lead. Check that the plug supplied fits your supply – should you require a new mains lead, please contact your Arcam dealer. Logo is fitted with a transformer designed to accept nominal mains voltages from 100V to 240V.
Push the IEC plug end of the power cable into the socket on the back of Logo, making sure that it is pushed in firmly. Plug the other end of the cable into your mains socket and, if necessary, switch the socket on.
Logo is fitted with a main power switch on the rear panel, above the power inlet: make sure that this is switched on to use Logo.
If your logo is not to be used for a prolonged period, switch the unit off at the main power switch.
Indicator LED
An indicator LED is positioned across the top edge of Logo's cabinet. When the indicator LED is off, it indicates that the speaker is completely disconnected from the mains. A blue
light from the indicator shows that the speaker is powered up and ready for immediate use. A red light from the indicator shows that the speaker is in standby (power-saving) mode and will power up as soon as an audio signal is received.
Standby switch
The push-in STANDBY switch provides two settings: AUTO and MANUAL.
'Auto' (bullon out) switches Logo's
amplifier to standby after a period of
idleness (about 15 minutes) when no audio signal has been received. MANUAL' (button in) means that Logo's amplifier is on whenever the unit is receiving mains power.
Interconnect cables
We recommend the use of high-quality screened audio interconnect cables. Poor quality cables will degrade the performance of your system. All cables should be kept as short as is practically possible. It is good practice when connecting your equipment to make sure that the mains power supply cabling is kept as far away as possible from your audio cables. Failure to do so may result in unwanted noise in the audio signals.
Note: When connecting Logo to signal leads, or when moving Logo to a new position, make sure that the unit is not receiving power by switching off and disconnecting the power lead.
Connecting to a sound source
Check that your sound processor/receiver is switched off before connecting logo. Failure to do this may result in both speaker and amplifier damage.
If your sound source has a PRE-OUT SUB or LFE OUT output, connect this to IN LFE on the back panel using RCA (pnono) connectors at each end. If your sound source does not have a SUB or LFE output, connect the left and right channels of the stereo pre-amp output (PRE OUT L and PRE OUT R) to IN L and IN R, respectively.
You may connect both the LFE and the L and R outputs to Logo if you wish to use both the LFE channel and to supplement the bass response of 'Large' Left and Right speakers.
out L, out R and out Ure provide line-level outputs for 'daisy-chaining' further units, in a multi-room installation, for example.
After connecting
Turn the sound source amplifier volume down to minimum before switching on. Switch the source amplifier on, select a source signal, then gradually increase the volume to the required listening level.
Care of your speaker
Running-in
In the same way as a new car requires a 'running-in' period, so do all loudspeakers. Your Logo may sound good when you first connect it, but with time it will improve dramatically. Expect about 50 hours use before the full potential of your Logo is realised.
Cleaning
To clean your speaker simply use a soft, slightly dampened cloth to wipe off any dust or dirt. Do not use solvent-based or chemical cleaning products as these may damage the finish of the speaker cabinet.
Power handling
Arcam speakers are designed to reproduce recorded music under normal domestic conditions. We do not recommend nor warrant them for commercial applications, such as discotheques, public address, etc.
speaker positioning
The advice given here is a general guideline for setting up speakers. Refer to the documentation supplied with your speakers for more precise positioning and installation information, and see www.dolby.com/consumer/home_entertainment/roomlayout.html for useful information on listening-room layouts.
Room acoustics
Your room's shape and how it is furnished will affect the sound you hear. For instance, too many bare surfaces can cause reflections that may add harshness to the sound. Carpets, wall hangings and curtains can all help.
If you have a choice of listening rooms, avoid one that is perfectly square or has one dimension exactly twice another. Such a room can aggravate resonances that colour the sound.
The closer you place a speaker to corners and the intersection of wall and floor or wall and ceiling, the stronger the bass output, which may over-emphasise the bass. Moving a speaker just a few inches can sometimes make a big difference.
Speaker setup
Proper speaker placement is the key to the best home theatre sound (see diagram).
As a rough guide, speakers should be placed on rigid stands at about 15cm from the rear wall and at least 60cm from any side wall. Speakers should never be placed on the floor (unless they are floor-
standing speakers), or in corners. The speaker drivers should be at, or a little above, ear level when seated. If possible, centre your seating area between the surround speakers.
The final sound will depend on the acoustics of the listening room and experimenting with speaker positioning is very worthwhile.
Subwoofer
The location of Logo will affect the overall sound quality. Placing the subwoofer next to a wall or in a corner will often boost efficiency and give a cleaner low bass sound. However, all rooms react differently and we recommend that you experiment with subwoofer positioning.
Speaker stands
The more firmly a speaker is held, the better it will sound. We recommend the use of rigid metal stands of 40–60cm height. Properly damped types that do not 'ring' when tapped with a pencil (either by virtue of construction, or because they are filled with dry silver sand) will bring out the best in a speaker. Ensure that the stands and/or speakers do not wobble.
Sub/full range+sat system
This is a surround-sound system (such as Arcam's Solo Movie S.1) where full range I and R speakers are combined with satellite (or with full range) rear speakers. The system should be connected with both the sub, subwoofer or use output connected to IN LFE and Left/Right preamplifier outputs attached to IN LIN R on Logo.
In such systems, Logo can be set up to work with two crossover frequencies. One frequency is set up for the rear speakers using the surround amplifier crossover, and one frequency for the full range Left and Right speakers, using the Logo crossover.
Direct mode in Arcam surround amplifiers
If you wish to have your system set up to use the crossover in the surround amplifier for 5.1 or 7.1 material, but use Left and Right full range speakers with Logo filling in for two-channel material, you can use Direct mode.
Connect the amplifier and Logo as in the Sub/full range+sat system diagram. In the amplifier, set up all speakers to 'Small'; this redirects bass to Logo via the LFE channel. To use the system's full range, activate 'Direct mode' for two-channel sources. This sends the full range signals to the Left and Right speakers and use the IN DIN R inputs to Logo via its own crossover.
Stereo system with no LFE
This is a typical two-channel system (such as Arcam's Solo). Logo is connected to L/R preamplifier outputs. The crossover frequency on Logo should be adjusted to the low frequency roll off of the main speakers (see the manual for your speakers for this information). The Q-control (x-over q) can be used to fine-tune the integration of Logo and your main speakers.
Sub/sat system
This is a surround-sound system (such as Arcam's Solo Movie 5.1) where all the main speakers are satellite speakers, defined as "Small". Logo is connected to output marked sub, SUBWOOFER or LIFE.
The LTE input bypasses the crossover in Logo, so the crossover frequency should be set by the surround sound amplifier. For the crossover setting, please see the response of your satellite speakers which may vary from around 70Hz for large satellites, to 150Hz for small satellites. We recommend 80Hz as a starting point if you are unsure.
The subwoofo's has two jobs: firstly to reproduce accurately and with sufficient power the sub-bass that other 'smaller' speakers cannot (the centre speaker is almost always a 'small' speaker); and secondly to reproduce the 'I' or low frequency effects (LFE) track of 5.1 or 7.1 material.
For optimum results, the subwoofer must be set up in the correct relation to the other speakers in the system. The two relevant controls are the crossover point and the subwoofer level. The crossover point establishes the frequency below which signals are redirected away from 'small' speakers toward the subwoofer. Setting the subwoofer level ensures signals that are of equal volume achieve the same sound pressure level no matter what frequency they are or which speaker they come from (i.e. subwoofer or satellite speaker).
In most surround-sound systems, two crossovers are available: one in the surround-sound decoder and one in the Logo unit.
In order to get the optimum sound in a variety of systems, Logo allows these controls to be used independently for systems with 'Large' front speakers and an LFE output from the surround-sound decoder.
Recommended settings for use with Muso speakers
Arcam's Muso satellite speakers ideally complement the sound quality and design values of Logo. The recommended settings of Logo for use with Muso speakers are:
| X-OVER FREQ | 90Hz |
| X-OVER Q | 0.5 |
| VOLUME | 8 |
| PHASE | 0^ |
Crossover frequency setting
In most systems, a crossover point for Logo of 901-lz is recommended.
If your satellite speakers are very 'Small' (and thus cannot reproduce much bass) you might like to set the crossover point higher than this figure to allow Logo to do more of the work. However, be aware that the higher the crossover point, the more directional the low frequency sounds, thus the more easily identifiable is the subwoofer's physical position
If your satellite speakers can reproduce reasonable bass, you can try a lower crossover point. Experimentation and listening will guide you to the right spot.
Crossover Q setting
The x-over q setting controls the slope of the trace beyond the cutoff frequency, in ctBioctave. The aim is to make a 'mirror image' match with the slope of the high-pass filter—a steep cut-off of the high-pass filter from the sound processor/receiver should be matched by a steep cut-off of the low-pass filter from Logo. Similarly, if the sound processor/receiver provides a more gradual cut-off, the x-over q setting should have a lower value.
Volume level setting
Accurate volume level setting for a subwoofer ideally requires specialist measuring equipment such as a Real Time Spectrum Analyser or RTA. A regular SPL (Sound Pressure Level) meter will not work for this! For most systems though simple experimentation by ear will suffice. Start with a medium settling (5) and experiment with volume until low frequency sounds can be heard as part of the main sound and not traceable to the subwoofer directly. Most sound processors or receivers allow Sub levels to be trimmed 'on the fly' to counter excessively high or low levels from particular source material.
Phase setting
This has two settings: with the PHASE button out (0°) and with the button in (180°).
A phase delay may be used to counteract the effect of sound waves from Logo interacting with and partially cancelling out or unduly emphasising sound from the satellite speakers. This effect depends critically on the relative positioning of subwoofer and satellite speakers and can also be remedied by relocating the subwoofer a short distance. The phase selling is available if relocation is not possible or impractical.
