Cyrus Mono X User Instructions

Welcome to the world of Cyrus!

Congratulations on your choice of Cyrus Hi-fi 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 Mono X safely and correctly.

Preparations for Installation

Before installing the Mono X check that the following items are included in the
accessory box.

• Power Cable

• 4 Loudspeaker plugs (certain markets only)

• 2 MC-Bus cables

After removing these items, please retain the packaging.

Install the Mono X in a well ventilated location away from sources of high
temperature, dust or humidity. Never stand the Mono X under another unit or
on any surface likely to hamper its cooling or ventilation.

INSTALLATION

3. Cooling Fan 9. IEC Power Inlet

4. Balanced (BAL) Input 10. Mains Fuse Holder

5. RCA (phono)/BAL Input Selector 11 Power Switch

6. Unbalanced RCA (phono) Input

Connecting to the AC Mains Supply

Connect the socket on the AC Power cable to the Power inlet i on the rear panel of
the Mono X. Now connect the cable to a suitable AC power point.

The mains power switch 1) on the rear panel of the Mono X should be left on
for normal operation, except when left unattended for a long period when it
should be switched off or disconnected from the AC supply.

Identifying System Channels

Each Mono X drives a single speaker. In a stereo system two Mono Xs are
necessary, in an AV system, up to 5 Mono X amplifiers will be necessary.
Before proceeding to connect your amplifiers, take some time to organise your
system so that you can easily identify which amplifier will be connected to
each speaker.

Connecting a Pre-Amplifier or Surround Decoder

Phono (RCA) f and Balanced input connectors d are available to link the
Mono X to a pre-amplifier or surround decoder.

Phono (RCA) connections are recommended unless the Mono Xs are a long
distance from the pre-amplifier/decoder, or beside a loudspeaker, then
balanced XLR connections

All Mono X’s must use the same method of input connection.

d may give improved performance.

Input Connection via phono (RCA) interconnects

Set the input selector switch e to RCA. Connect a single phono interconnect
from the phono input f of each Mono X to the corresponding output of the
pre-amplifier/decoder.

In the system illustration Fig.4a, a Cyrus preamplifier is connected to two
Mono X amplifiers, one for the left channel and one for the right channel. Input
connections are shown using phono interconnects.

Input Connection using Balanced XLR cables

Set the input selector switch e to BAL. Connect a 3-pin XLR cable from the
balanced input d of each Mono X to the corresponding XLR output of the pre­amplifier/decoder.

Connecting Loudspeakers

Fitting the loudspeaker plugs

Check for polarity indicators (+ and -) on the loudspeaker cable and fit the
plugs provided. Observe any signal directionality markings indicated on the
cable. If an arrow is printed on the cable it should point toward the speaker.

If additional or replacement loudspeaker plugs are required for the Mono X
ensure that the correct ‘BFA’ type are purchased.

Connecting the cables

After checking all the assembled cables for polarity they can be plugged into
the loudspeakers and amplifiers. The ‘+’ and ‘-’ terminals of each loudspeaker
must be connected to the matching ‘+’ and ‘-’ terminals of each amplifier as
follows-

Connect the left loudspeaker to the rear panel sockets
and b (black speaker plug) of the left channel Mono X. Connect the right
loudspeaker to the rear panel sockets
speaker plug) of the right channel Mono X.

Dual outputs are provided for the convenient connection of bi-wiring speaker
cables. Fig.4a shows a wiring schematic for a bi-wired stereo system.

(black

Chain Output

The Chain output g allows more than one Mono X to be connected to each
channel of a pre-Amplifier or decoder.

Note: The Chain output is operational whether phono (RCA) or Balanced XLR
input connection is made to the Mono X.

Bi-Amplification

The Chain facility can be used with two or more Mono X amplifiers per
channel, for Bi/Tri-amping by connecting the Chain output of the first Mono X
to the phono inputs of the next Mono X. Such a bi-amplified system provides
the sonic benefits of totally separate power amplification for the bass and
treble units of the loudspeakers.

In the bi-amplified system illustration Fig.4b, a Cyrus preamplifier is connected
to four Mono X amplifiers - two for the left channel and two for the right
channel. Phono input connections are shown.

Note: The Chain output is operational whether phono (RCA) or Balanced XLR
input connection is made to the Mono X.

Gain Matching

All Cyrus power amplifiers, and all power amplifier stages in Cyrus integrated
amplifiers have the same voltage gain characteristics. This means that you
can use the Mono X in conjunction with any Cyrus amplifier for bi-amping, etc.
without any set-up adjustments being required.

MC-Bus System Connection (Optional)

Connecting the MC-Bus sockets h of the Mono X in an MC-Bus system

provides unified system power control. An MC-Bus loop is established by
connecting single phono cables from the MC-Bus output of one unit to the MC­Bus input of another in a daisy-chain. Complete the loop by returning the MC­Bus output of the final component to the MC-Bus input of the first (see
example system connections in Fig.3).
With MC-Bus established you can control the power function of the system
from the front panel or remote control of the main Cyrus amplifier or Surround
Processor.

OPERATION

Key to the front panel drawing (Fig.2)

12. Standby Switch

13. Standby Light

14. Mute Light

Switching On

When power is applied, the STANDBY key 1@ may be used for power control.
The Standby light 1# shows red when the Mono X is in Standby and green
when operational.

Remote power control can also be enabled by connecting the MC-Bus sockets

h of the Mono X to a Cyrus system which includes a Preamplifier, Integrated

amplifier or Surround decoder. A number of Mono Xs may be connected in
this way to provide remote standby control of all the system power amplifiers.

Mute Indicator

The MUTE Indicator 1$ will glow red if the protector of the Mono X switches in.
This occurs for a few seconds following Standby operation or if a temporary
overload condition arises. If the MUTE Indicator glows continually, refer to the
Troubleshooting Guide.

Cooling

Due to the substantial power of the Mono X, air-cooling is provided via a fan

c. The fan in the Mono X features an Intelligent Power Controller. When the

unit is idling the fan turns off. As the amplifier warms up the fan progressively
speeds up, reaching maximum speed at maximum temperature. In this way
the fan speed is always related to the power output of the unit and fan noise is
barely discernible even at low volume levels. In quiet passages and between
tracks on a CD, the fan will slow down so as not to encroach on the listening
experience.

TROUBLESHOOTING GUIDE

If your Mono X is not operating properly, disconnect the power and check all
connections using the notes in this handbook. If problems persist, the
checklist below may be helpful.

If you are in doubt, consult your dealer.

No sound from both speakers

Check that the pre-amplifier and the power
amplifiers are on.

Check that the pre-amplifier and the power
amplifiers are not muted.

Check that the pre-amplifier responds to
front panel commands.

Check that the relevant program source is
selected.

Check that the correct amplifier input is
selected.

Check that the loudspeakers are
connected.

No sound from one speaker

There may be a short circuit in the
speaker connections.

The standby lights should be
green.

The red Mute lights should not
be lit.

Tape Monitor should not be
selected.

The source device must be
operating normally.

The RCA/BAL switch must be
switched to the appropriate
input.

The connection at the
terminals of the loudspeakers
and the Mono X should be
checked.

The protection circuit will
operate and the red Mute light
will stay lit.
