NOTE: When connecting inputs to the DAC X+, ensure that only digital audio
sources are connected to 'Digital' inputs.
Connecting Digital Audio Sources
The digital audio inputs of the DAC X+ 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 (for replay of 2 channel PCM programs only)
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 X+ can be re-named at the set-
up stage.
Connecting the DAC X+ to an amplifier
The DAC X+ requires an external amplifier or preamplifier to provide input
selection and volume control functions for the system, and to drive the
speakers. Two output options are available from the DAC X+ via either
standard RCA phono outputs, or via balanced audio connections.
CAUTION:- Do not connect power amplifiers to the Fixed output.
Connecting to amplifiers with phono inputs
With suitable phono interconnects, connect from the Fixed Out terminals b to
a suitable amplifier line input. All line level inputs, such as CD, TU, AU, AV
are suitable. We recommend selection of an input that corresponds to the
primary source connected to the DAC X+. If the primary source is a CD
player, the CD input is recommended, if the primary source is a DVD player,
the AV input is recommended etc. For Cyrus amplifiers with optional MC-BUS
connection, see also the section 'MC-BUS connections'.
Connecting to amplifiers with balanced inputs
If the amplifier is equipped with balanced inputs, the balanced outputs of the
DAC X+ may be used. With suitable balanced interconnects fitted with XLR
connectors, connect from the Balanced Output terminals a of the DAC X+ to
the input of the amplifier. Dual balanced outputs are provided for connection
to a second amplifier or recording device with balanced input.
Connecting to the Digital Output
An optical Digital Output d is provided for the connection of another digital
device to the DAC X+. 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 that will upgrade the sonic
performance of your DAC X+ and other Cyrus products. When a DAC X+ /
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 X+, plug the connector on the umbilical
cord of the PSX-R into the Multi-Pole socket on the rear of the DAC X+ 1!.
You will need a mains supply for both units.
NOTE: Connection of a PSX-R is detected automatically, so no internal
adjustments are required.

MC-BUS Connections
MC-BUS operation
Connecting the MC-BUS sockets c of the DAC X+ to those of other Cyrus
products is an option that provides unified system power control. With MC-
BUS connections established the power function of all connected Cyrus
components may be controlled from the system amplifier or its remote control.
All connected components will also set to Standby when the amplifier 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 X+ with a CD player, tuner and amplifier.
MC-BUS configuration
Within a Cyrus system, the DAC X+ may be connected to either the CD, TU,
AU or AV input, as selected by the user to best match their system
components. To ensure that the DAC X+ will power on when the correct input
is selected, the MC-BUS response may be configured accordingly.
The factory response enables the DAC X+ to switch on when the CD input is
selected from the amplifier. To change the response, refer to the paragraph
'DAC X+ Connected to' in the section 'Setting up the DAC X+'.
