Cyrus DAC X Signature

connecting digital Audio sources

The digital audio inputs of the DAC X Signature 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 Signature
can be re-named at the set-up stage.

connecting the dAc X signature to an amplifier

The DAC X Signature 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
Signature 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 Signature. 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 Signature may be used. With suitable balanced interconnects
fitted with XLR connectors, connect from the Balanced Output terminals
a of the DAC X Signature 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 Signature. 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 Signature and other Cyrus products. When a
DAC X Signature / 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 Signature, plug the connector on the
umbilical cord of the PSX-R into the Multi-Pole socket on the rear of the DAC
X Signature 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

Mc-bus operation

Connecting the MC-BUS sockets c of the DAC X Signature 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 diagram shows an example of MC-BUS
wiring for a Cyrus DAC X Signature with a CD player, tuner and amplifier.

Mc-bus configuration

Within a Cyrus system, the DAC X Signature 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 Signature will power
on when the correct input is selected, the MC-BUS response may be
configured accordingly.
The factory response enables the DAC X Signature to switch on when the
CD input is selected from the amplifier. To change the response, refer to the
paragraph 'DAC X Signature Connected to' in the section 'Setting up the DAC
X Signature'.
