Cyrus III Amplifier CAUTIONS

Your Cyrus III Amplifier is factory set to operate from a
fixed mains supply voltage, which is marked on a label at
the rear of the unit. Before connecting, check that this
voltage is the same as your mains supply, i.e.

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

UNPACKING

Always follow the instruction handbook and retain it in a
safe place for future reference.

Before proceeding with installing the Cyrus III Amplifier,
ensure that the following items are included in the
accessory box:

• Instruction Manual

• Power Cable

• Remote Handset

Avoid installing the Cyrus III Amplifier in a location
which is exposed to direct rays of the sun, or near to hot
appliances or radiators. Placing and using the amplifier for
long periods on heat-generating sources will affect
performance and may damage the cabinet. Installation in a
damp or dusty environment may result in malfunction or
accident.

RE-LOCATING

The Cyrus III Amplifier is supplied ready for use in your
location. Care has been taken to ensure that the power
supply requirements are correctly set. Consult your
Mission distributor to arrange for conversion of your
Cyrus III should you move to another area with a different
mains voltage supply.

Cyrus III Amplifier INSTALLATION

POSITIONING THE UNIT

The Cyrus III may be positioned as a free standing unit or
alongside another piece of audio equipment. Never stand
the Cyrus III under another unit. This may adversely affect
the efficient cooling of the Cyrus III. Never place the
Cyrus III on a carpet or similar material which may
hamper normal ventilation.

CONNECTING THE UNIT

The Mains Supply

The moulded IEC connector of the mains lead supplied

14

should be plugged in to the power inlet

on the rear of

the unit.

15

The mains fuse

is located on the rear panel next to the
power switch. It must only be replaced with the following
types:

IMPORTANT

NOTE TO USERS OF PSX-R WITH CYRUS III

In order to use a PSX-R regulated power supply with the
Cyrus III Amplifier, certain internal adjustments must be
made to the Cyrus III which can only be carried out by
an authorised Mission distributor or his agent.
Connection of the PSX-R to a Cyrus III which is not
correctly adjusted will result in fault condition display
on the Cyrus III. The Cyrus III fault indication system is
fully described in the Cyrus III handbook.

Connecting a PSX-R Power Supply (Optional)

If a PSX-R is to be used with the Cyrus III, proceed to
connect the umbilical cord of the PSX-R to the 5-pin
Cannon input socket of the Cyrus III. When correctly
fitted, the connector will latch into place in the socket.
Note that when a PSX-R is in use, both the PSX-R power
supply and the Cyrus III will require mains power.

U.K. / Europe - 230V T1A/20mm
N. America / Far East - 115V T2A/20mm

In the U.K., the Cyrus III comes with the mains plug
fitted. In the unlikely event that the plug fuse should need
replacing ensure that it is only replaced with a 3 Amp
Fuse.

INSTALLATION Cyrus III Amplifier

Connecting a Turntable

Connect the phono cable from the turntable to the phono
input - PH

8

. Be sure to follow colour coding of the
plugs to keep left and right channels correctly ordered. If
the turntable has a ground wire fitted, connect this to the
Turntable ground connection

13

of the amplifier.

Note that the phono pre-amplifier of the Cyrus III is
suitable for use with a pick-up cartridge of either moving
magnet or high output moving coil design. A low output
moving coil cartridge will require a step-up transformer or
pre-amplifier to be used externally. Your dealer can advise
if this is necessary.

Connecting other Inputs

Connect a phono cable between each system component
and the rear panel sockets as marked on the rear panel
diagram. At all times observe the colour coding of the
phono cable for left and right channel identification. The
Cyrus III provides for connection of a CD Player -CD
a tuner - TU

10

and an auxiliary input - AU

,

9

, a video recorder or video disc player - VI

6

.

7

The AU input can be used for connection of a wide variety
of products such as a second CD player, tuner or VCR, an
electronic keyboard, an organ or a second tape deck if
only replay is necessary. Always check the technical

specification of these products before connecting to your
Cyrus III. Consult your dealer if in doubt.

Connecting a Tape Recorder

Two phono cables are necessary for connection of a tape
recorder when used. Firstly, connect a phono cable from
the Output or Playback sockets of the tape recorder to the

5

Tape Input - TP IN

of the Cyrus III. Then connect a

second phono cable from the Input or Record sockets of
the tape recorder to the Tape Record Output - TP OUT

4

sockets of the Cyrus III.

Connecting Loudspeakers

The left and right loudspeakers are connected to the rear
panel sockets

1

and

2

of the Cyrus III respectively

using the plugs provided. First, fit the plugs to the
loudspeaker cables. Carefully note that the cable carries
marking or colours for polarity, (+ and -) may also be
marked for direction with an arrow. For correct operation,

,

it is essential that the (+ and - ) terminals of the amplifier
are connected to the corresponding
(+ and -) terminals of the loudspeakers. When fitting the
plugs to the cables be sure to line up (+ and -) at each end.
The loudspeaker plugs can now be fitted to the amplifier
sockets.
