Frequently Asked Questions - DAC XP Cyrus Audio

What digital audio sources can I connect to the DAC XP?

You can connect CD players, DVD players (for 2-channel PCM only), digital tape/disc recorders, digital radio, and satellite receivers. Use a suitable Toslink optical or digital phono interconnect to connect each source to one of the six digital inputs.

How do I change the input names on the DAC XP?

Press the front panel setup button to enter the setup menu, then cycle through the options until you reach 'Name Input X' for the desired input. Rotate the volume control to choose a name from the list, then continue until 'Storing settings' is displayed.

What display modes are available?

There are three display modes: small input (volume top, input middle, sample rate bottom), large input (volume top, larger input name below), and large volume (large volume characters at the bottom with a bargraph above).

How do I connect a PSX-R external power supply?

Plug the connector on the umbilical cord of the PSX-R into the multi-pole socket on the rear of the DAC XP. Both the DAC XP and the PSX-R must be connected to mains power. This powers the analogue section of the DAC stage from a clean, stable source.

Why is there no sound from a particular source?

First check that the correct input is selected and correctly named. Ensure the source is not paused and that its audio format is compatible (the DAC XP does not decode multi-channel PCM). Also verify all physical connections are secure.

What is the MC-Bus connection for?

The MC-Bus connection links Cyrus components to provide unified system power control. When connected in a loop, the DAC XP can switch on related components when an input is selected, and set all to standby together. Single phono cables connect MC-Bus outputs to inputs.

Can I adjust the sensitivity of the analogue inputs?

Yes, use the setup menu to select 'Trim Input 7' or 'Trim Input 8' and adjust the level by up to ±4 dB. This helps equalise the volume from analogue sources with digital sources.

How does the remote control work for stereo and multi-channel systems?

In a stereo system, press CD, TU, or AV to control those sources and select corresponding DAC XP inputs. Volume, balance, and mute always control the DAC XP. In a multi-channel system with a Cyrus surround decoder, use AV-S to control DVD and decoder, and SETUP for decoder setup; the DAC XP responds accordingly.

What is the fixed output used for?

The fixed output bypasses the internal preamplifier and volume control, feeding the DAC stage directly. It can be used with an external system preamplifier or for high-quality tape recording from digital sources. Never connect power amplifiers to this output.

What maintenance and safety precautions should I follow?

Unplug the unit before cleaning and wipe with a damp cloth; never use liquid cleaners. Do not expose to water, heat sources, or poor ventilation. The product contains no user-serviceable parts; refer all servicing to qualified personnel and insist on manufacturer-specified replacement parts.

NOTE: When connecting inputs to the DAC XP, ensure that only digital audio sources are connected to 'Digital' inputs.

Connecting Digital Audio Sources to the DAC XP

The digital audio inputs of the DAC XP are compatible with a number of different digital audio sources. These include-

• Digital Audio output from a CD player
• DVD players (for replay of 2 channel PCM programs only)
• Digital tape/disc recorders
- Digital Radio
• Digital Satellite receivers

Using a suitable Toslink optical or Digital phono interconnect, connect each digital audio source to one of the inputs 1\~6. Make a note of the input number used for each source as the inputs of the DAC XP can be re-named at the set-up stage.

Connecting Analogue Audio Sources to the DAC XP

Analogue Inputs 7-8 are available for the connection of stereo analogue audio sources to the DAC XP. Inputs 7-8 are intended for use with analogue program sources which include-

• Analogue output from CD/DVD Players
- Televisions
• Analogue Satellite Receivers
• FM Radio tuners
• Analogue VCRs/Tape recorders
• Cyrus surround decoder

Connecting Power amplifiers

External power amplifiers are necessary to drive the system speakers. Both stereo and high power monoblock Cyrus power amplifiers are available to partner the DAC XP and a choice of RCA phono or balanced outputs is provided.

NOTE:- Take care to connect each of the DAC XP output channels to the correct power amplifier and loudspeaker.

Connecting to power amplifiers with phono inputs

With suitable phono interconnects, connect from the Pre Out terminals ¹⁵ to the power amplifier inputs. The system loudspeakers may then be connected to each power amplifier. Dual outputs are provided to enable the connection of two amplifiers for bi-amping.

Connecting to power amplifiers with balanced inputs

With suitable Balanced interconnects, connect from the Balanced Output terminals ① to the power amplifier inputs. The system loudspeakers may then be connected to each power amplifier. Dual outputs are provided to enable the connection of two amplifiers for bi-amping.

Fixed output

The Fixed output is connected directly to the internal DAC stage of the DAC XP and bypasses the internal preamplifier and volume control. It may be used to feed the DAC stage output to an external system preamplifier, or for high quality tape recording from digital sources.

NOTE:- Analogue inputs 7 and 8 are not routed to the Fixed output.

CAUTION:- Do not connect power amplifiers to the Fixed output.

Connecting a Cyrus Surround Sound decoder to the DAC XP

In a Cyrus multi-channel surround sound system the surround decoder may be connected through the DAC XP to share the same front channel power amplifiers.

In this case, connect a stereo phono interconnect from the front channel outputs of the surround decoder to the Input 7 sockets ⑬ of the DAC XP. For this system to function correctly both the DAC XP and the Cyrus surround decoder must be included in an MC-Bus connection loop and the 'Cyrus AV' input name must be set for Input 7 (see 'MC-Bus' section and 'Input names' in the 'Setup menu' section).

When set up in this way, the DAC XP will automatically check for the presence of the decoder when the 'Cyrus AV' input is selected, then lock the DAC XP volume setting to an appropriate level.

Connecting to the Digital Output

An optical Digital Output ④ is provided for the connection of another digital device to the DAC XP. This may include such devices as a multi-channel surround decoder or a digital tape/disc recorder. The currently selected digital input signal will be routed to this output.

External Regulated Power Supply - PSX-R

The PSX-R is a unique DC power supply which will upgrade the sonic performance of your DAC XP and other Cyrus products. When a DAC XP / PSX-R combination is installed, the analogue section of the DAC stage is powered from this clean, stable power source while other requirements are supplied internally. This ensures complete isolation of the sensitive analogue sections reducing AC mains-borne noise and power supply ripple.

To connect the PSX-R to the DAC XP, plug the connector on the umbilical cord of the PSX-R into the Multi-Pole socket on the rear of the DAC XP ⑪. You will need a mains supply for both units.

MC-BUS Connections

MC-Bus operation

Connecting the MC-Bus sockets ③ of the DAC XP in an MC-Bus system provides unified system power control. With MC-Bus connections established the power function of all connected Cyrus components may be controlled from the DAC XP front panel or remote control. Refer to the following table for Cyrus components that will be activated by the DAC XP when the inputs have been named as listed -

Input name	Power on response
CD	CD players, power amplifiers
TUNER	Tuners, power amplifiers
AV	DVD players, power amplifiers
CYRUS AV	DVD players, surround decoders, power amplifiers
DVD	DVD players, power amplifiers

Follow the instructions in section 'Setting up the DAC XP' to set the listed input names.

All connected components will also set to Standby when the DACXP is set to Standby.

MC-Bus connection

An MC-Bus loop is established by connecting single phono cables from the MC-Bus output of one unit to the MC-Bus input of another. Complete the loop by returning the MC-Bus output of the final component to the MC-Bus input of the first. The drawing in Fig 3 shows an example of MC-Bus wiring for a Cyrus DAC XP with a CD player, tuner and power amplifier.

SETTING UP THE DAC XP

There are many configuration options available in the setup menu to customise the DAC XP to best match each individual system.

The setup sequence is activated by pressing the front panel set up button ②. Repeated pressing of the setup button will step through each available setup option until 'Storing settings' is shown on the display. When each setup screen is displayed, changes may be made to the settings by rotating the front panel volume knob.

The setup sequence will cancel after 5 seconds of inactivity.

The setup menu options are shown here –

Some examples of the setup display screens are shown in Fig 4.

Phase adjust (Fig 4a)

This menu option sets the audio phase for the DAC. The factory setting is normal. Some listeners may prefer the inverted setting with their systems or for when playing particular recordings.

Filter adjust (Fig 4b)

This menu option gives two settings for the digital filtering of the DAC stage. Choose your preference of Fast or Slow roll-off by auditioning some of your favourite tracks with each setting.

Display mode (Fig 4c)

There are three modes of display operation.

The ‘small input’ setting will show a three line display with the volume reading at the top of the display, the selected input in the display centre and the current sample rate/lock status at the bottom.

The ‘large input’ setting will show a two line display with the volume reading at the top and a larger input legend below.

The ‘large volume’ setting will display large volume characters at the bottom of the screen with the bargraph above.

Input names (Fig 4d)

When the DAC XP leaves the factory, the input names are set to correspond to the rear panel connections, for example Input 1 will display as- Input 1.

The name of any input may be changed to a choice from the following list-

• No source (off)*
  • LaserDisc, DVD, DVD 2, DVD-A, CD, CD 2, SACD
• Linkserver, Linkport
• Jukebox, Phono
  • Tuner, DAB, TV, AV, Cyrus AV*, Satellite, Satellite 2, Cable
  • VCR, VCR 2, Tape, MiniDisc, DAT
  • PC, Games, Keyboard, Aux

To change the names of the inputs, we recommend making a list of each input number with your preferred name from the choices above before setting the names.

There are two special function input names marked *. 'No source' is used to name inputs which have no source connected to them. These input numbers will not then appear in the input selector sequence. 'Cyrus AV' is reserved for the connection of Cyrus surround sound decoders. When a Cyrus surround decoder is connected to an analogue input named 'Cyrus AV' the DAC XP will check the system for the presence of a Cyrus surround decoder and, if found, lock out its volume control at a precise setting. Normal volume operation will be restored when any other input is selected.

Input trims (Fig 4e)

It is possible to adjust the sensitivity of analogue inputs 7 and 8 by selecting the appropriate trim option from the menu. This enables the volume level when playing low or high output source components such as tape decks or tuners to be equalised with the digital system sources.

Switching On

The mains power to the DAC XP should normally be left on unless left unattended for a long period when the mains power at the wall socket should be switched off or the product disconnected from the AC supply.

When power is applied, the STANDBY key ⑯ is used for power control. The Standby light ⑰ shows red when the DAC XP is in Standby and green when operational.

Selecting an input

Inputs may be selected from the front panel INPUT SELECT buttons ②4 or with the remote control INPUT SELECT keys. As a new input is selected the input name/number are displayed briefly. The main display indication for input/volume can be selected from the three options in the setup menu.

The factory default ‘small input’ display option will also identify the sample rate of the selected source and indicate ‘Invalid Audio Format’ for program material which the DAC XP will not decode (such as multi-channel digital sound from DVD players).

Volume and Balance

The level control ⑳ of the DAC XP performs the dual functions of volume and balance.

Volume: In normal mode the level control sets the volume in 1dB steps. A bargraph and a numeric scale at the top of the display window show the current volume setting. The last used volume setting is stored when the unit is set to standby.

If the volume is left at an abnormally high volume level before entering standby, the level will be reduced automatically to a safe level of -15dB for next use.

Balance: Press the balance control key ② to change the mode of the front panel rotary control ⑩ to set Left/Right Balance. The volume display will also change to show a graphic and numeric display of the balance setting.

Mute

Pressing the MUTE Key ②3 will mute the volume to minimum level without disturbing the existing volume setting. When muted the display will show that volume is muted. Move the volume knob up or press the Mute key to fade back up to the original volume setting.

Programmable Input Sensitivity

You may find an audible difference in level when switching from digital inputs to one of the two analogue inputs due to the differing outputs of your source components. The unique calibration memory of the DAC XP can be programmed to match the sensitivity of these inputs with reference to the digital inputs. Input sensitivity settings are made through the setup menu. Refer to the section 'Setting up the DAC XP' for more details.

REMOTE CONTROL

The DAC XP is supplied with a remote control designed to operate a full system of Cyrus products.
