Cyrus DAC X

Welcome to the world of Cyrus!

Congratulations on your choice of Cyrus Audio-Visual products. Our state-of-the-

art design technology and outstanding quality of manufacture has won

countless awards around the world. We are confident that you will derive

great pleasure from owning a product from one of the most recognised and

respected manufacturers of hi-fi equipment.

Please read these instructions carefully before commencing installation. They

provide full guidance to help you install your Cyrus DAC X safely and

correctly.

Preparations for Installation

Before installing the DAC X check that the following items are included in the

accessory box.

•

Warranty Card (back cover of this handbook)

•

AC Mains Cable

•

2 MC-Bus phono cables

After removing these items, please retain the packaging.

Install the DAC X in a well ventilated location away from sources of high

temperature, dust or humidity. Never stand the DAC X under another unit or

on any surface likely to hamper its cooling or ventilation.

IMPORTANT NOTE:- To avoid damage to your system, always ensure that

mains power is disconnected from all system components until installation is

complete.

NOTE: When connecting inputs to the DAC X, ensure that only digital audio

sources are connected to 'Digital' inputs.

Connecting Digital Audio Sources to the DAC X

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

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.

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

'DACX Connected to' in the following section.
