POWER SUPPLY: (Refer to Fig.1)

The moulded IEC connector of the AC cord supplied plugs into the power inlet
g on the rear of the unit. The mains fuse h is on the rear panel next to the
power switch. It must only be replaced as follows:

U.K. / Europe 230V T100mAL/250V 20mm
N. America 115V T200mAL/250V 20mm

The mains supply requirement for your Cyrus Phono X is marked on a label

on the rear panel. Before connecting, check that this voltage is the same as
your mains supply.

230V Products: Voltage Range 220V-240V
115V Products: Voltage Range 110V-120V

If you move to an area with a different mains voltage, contact your local Cyrus

distributor to have your product converted.

NOTE FOR UK CUSTOMERS:

The Phono X is supplied with a power cable terminated by a fused 13A mains
plug. This plug should not be removed but if it is removed, dispose of it safely
and do not re-use it. To connect a new 13A plug, proceed as follows: Connect
the brown wire to the terminal marked L or coloured red. Connect the blue
wire to the terminal marked N or coloured black. The internal plug fuse should
be 5A.

Cyrus Phono 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 Phono X safely and
correctly.

Preparations for Installation

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

• Warranty Card (back cover of this instruction manual)

• Power Cable

• 2 x Phono leads for MC-BUS connection

After removing these items, please retain the packaging.

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

temperature, dust or humidity. Never stand the Phono X under another
unit or on any surface likely to obstruct its cooling or ventilation.

2. Moving Coil Input 7. Power Inlet

3. Moving Magnet Input 8. Mains Fuseholder

4. Preamplifier Output 9 Ground terminals

5. MC-bus Connections

Connecting a Turntable

The Phono X accepts Moving Coil and Moving Magnet cartridge inputs.

If you have two turntables, one equipped with a MM and one with an MC
cartridge, both can be connected at the same time.

Before connecting a turntable to the Phono X, check the specification of
the cartridge which is fitted, then connect the turntable to the correct input
of the Phono X by referring to the following paragraphs.

Moving Magnet Input:

The MM input c accepts:

• Regular moving magnet cartridges

• High output moving coil cartridges (where MM input is

recommended by the cartridge manufacturer)

• Low output MC cartridges connected via step-up transformers

Moving Coil Input:

The MC Input b accepts:

• Low-output moving coil cartridges.
Your Phono X is provided with a loading switch a so that you can set the

correct load impedance for your MC cartridge. Three settings are

available, 10Ω, 100Ω and 1KΩ. Unless your cartridge instructions
recommend a lower value, we suggest you use the 1KΩ setting.

Some MC cartridges are load sensitive and may also require a
capacitance load to control high frequency response peaks. Each load
setting is therefore available with or without a 1nF shunt capacitor. The
shunt settings occupy the last three positions on the switch. Use
capacitance loading only if your cartridge instructions specifically advise
its use.

Shorting plugs

The Phono X is supplied with two shorting phono plugs. When using only
one input, insert these plugs into the unused input.

Note: These plugs must be used only as described above.

Ground Connections

Most turntables include a separate grounding wire.

There are three grounding systems in common use:

1. The motor and tone arm grounds are connected to a common
ground wire. Connect this wire to either the MM or MC ground
terminal i, depending on the cartridge used.

2. There are two ground wires, one from the motor and one from the
tone arm. Connect both wires to the appropriate ground terminal on
the Phono X.

3. There is no separate ground wire. Some units use the signal cable
outer return for turntable and tone arm grounds. Though not best
practice, the method is acceptable. No separate ground connection
will be necessary.

Some cartridges link a negative signal pin to the metal shield. This link
may make contact with the tone arm metalwork and cause a hum loop. If
you think this is the case with your turntable, ask your dealer before you
remove the link.

If you have an amplifier that requires a mains earth, do not use the MM or
MC ground terminals of the Phono X for this purpose. Use an appropriate
ground terminal on the ancillary equipment.

Output Connections

Connect the output sockets d of the Phono X to a line level (AUX) input
on your pre-amplifier. When connecting the Phono X to a Cyrus amplifier,
the AUX input labelled AU, AU1 or AUX/PH is recommended.

All signal connections should be via high quality audio interconnects. The
convention for phono connections is
WHITE or BLACK.

Right Channel RED, Left Channel

External Regulated Power Supply - PSX-R

The PSX-R is a unique DC power supply which will upgrade the sonic

performance of your Phono X. When a Phono X & PSX-R combination is
installed, analogue and signal related sections of the Phono X are
powered from this clean, stable power source while other requirements
are supplied internally. This ensures complete isolation of control circuits
and sensitive analogue sections reducing AC mains-borne noise and
power supply ripple.

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

OPERATION (Refer to fig 2)

Key to the front panel drawing:

1. Standby Switch 4 MM Input selector

2. Standby Light 5. MC Input selector

3. IEC Switch

Power Control

The mains power to the Phono X 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 a is used for power control. The
Standby light b shows red when the Phono X is in Standby and green
when operational.

Selecting an Input

Depress the MC e or MM key d to select the appropriate input. The red
indicator above the selected input key will turn on.

Playback Equalisation

The Phono X offers the choice of traditional RIAA playback response or
the newer IEC response. For most systems built from quality audio
components, Cyrus recommends the original RIAA response. If your
turntable is prone to feedback or rumble and/or your loudspeakers have
extended bass response, switching to the IEC setting will help to reduce
bass noise and distortion. The IEC response is also useful to reduce
large cone excursions due to warps.

1. Press the IEC key c to select IEC response.
The red indicator above the key will turn on. When the IEC indicator is not

lit, RIAA response is selected.

Mc-Bus System Connection (Optional)

This feature is usable if you own a Cyrus amplifier. By connecting the
Phono X to the recommended AUX input of your amplifier and setting up
MC-Bus connection for the system, the amplifier will switch on the Phono
X whenever the AUX input is selected. Refer to the relevant amplifier

handbook for MC-Bus wiring instructions.

If preferred, the MC-Bus response of the Phono X can be reconfigured to
always switch on with the amplifier, regardless of which input is selected.
This may be useful if the Phono X is connected to an input other than
AUX. To change the MC-Bus response, follow this sequence:-

1. Set the Phono X to Standby.

2. Press the IEC key c. and hold it down for two seconds, the

indicator above the IEC key will flash.

3. Take the Phono X in and out of Standby to register this setting.

To restore normal operation:

1. Repeat Steps 1 & 2 above, the IEC indicator will flash twice.

2. Take the Phono X in and out of Standby to register this setting.
