Cyrus 1 and Cyrus 2 Manual
CYRUS AMPLIFIERS
INTRODUCTION
Congratulations on your purchase of the Cyrus integrated stereo amplifier.
The Cyrus range of amplifiers are precision manufactured to the highest
standards and specifications. This results in a highly consistent and
reliable product.
This manual contains installation and operating instructions to enable the
user to connect up and operate the amplifier correctly, thus ensuring the
greatest satisfaction and long term use.
WARNINGS
Your Cyrus amplifier is factory set to operate from a fixed mains supply
voltage. This voltage is marked on a label on the rear of the unit. Before
connecting, check that this voltage is the same as your mains supply.
BEFORE CONNECTING to the mains supply ensure that the On/Off switch
is set to off (down).
DO NOT remove the amplifier cover under any circumstances.
DO NOT make any connections to, or disconnections from the amplifier
unless the amplifier is OFF and the VOLUME control is set to "MIN".
DO NOT change the position of the Selector switches unless the VOLUME
control is set to "MIN".
DO NOT ever select tape on both selector switches at the same time.
DO NOT allow the positive and negative speaker leads to touch.
DO NOT obstruct the ventilation grille on the top of the amplifier. Ensure
the unit has adequate all round ventilation.
DO NOT expose your amplifier to excessive cold or heat, direct sunlight,
humidity or water.
DO NOT use any chemicals for cleaning your Cyrus amplifier. Only a
slightly damp, soft cloth should be used.
The original packing should be retained and always used when transporting
the unit.
INSTALLATION
MAINS SUPPLY
A label at the rear of your Cyrus amplifier shows the appropriate mains
supply voltage and fuse rating of the unit. If the Tnains supply voltage in
your area is different, contact your dealer or a Mission service organisation.
The amplifier is connected to the mains supply via an IEC socket and the
mains cable. The IEC socket has an integral mains fuse. When connecting
the mains supply, ensure that the cable is connected to the amplifier first.
MAINS CABLE
The mains cable supplied with the unit is a three core type, and has an
integral plug attached. Units supplied for the UK market do not have a
mains plug, and therefore, an appropriate plug must be wired according to
the colour-code below and on the label attached to the lead.
All types of mains lead supplied (all countries), have a moulded IEC plug
which matches the IEC socket of your amplifier.
FITTING A MAINS PLUG (UK ONLY)
The mains supply cable should be attached to a standard 13 Amp mains
plug fitted with a 3 Amp fuse.
The wires in the mains supply cable are colour coded as follows;
•BROWN = Live
•BLUE = Neutral
•GREEN/YELLOW. = Earth
The Brown wire must be connected to the terminal that is marked "L" or
coloured RED. The Blue wire must be connected to the terminal that is
marked "N" or coloured BLACK. The GREEN/YELLOW wire must be
connected to the terminal that is marked with the letter "E" or coloured
GREEN or coloured GREEN AND YELLOW.
MAINS FUSE
Cyrus I:
•UK/Europe - 220/240V = T1A/20mm
•N.America/Far East - 100/120 = T1.6A/20mm
Cyrus II:
•UK/Europe - 220/240V = T1.25A/20mm
•N.America/Far East- 100/120V = T2.5A/2Omm
SITING THE AMPLIFIER
Your Cyrus amplifier can be sited as a free standing unit or stacked with
other units in an audio rack. However, since the power amplifier produces
a substantial amount of heat, positioning the unit at the bottom of the rack
should be avoided. Convected heat from the amplifier could adversely
affect other units stacked above, as well as overheat and damage your
amplifier.
The amplifier must NOT be sited near a source of heat or in a position
exposed to direct sunlight.
CONNECTIONS
Before making any connections to your amplifier, ensure that all units are
switched OFF, and disconnected from the mains.
Refer to the wiring diagram of your particular Cyrus amplifier for
connection details.
For best results, the loudspeaker cables used should be of high purity
copper and as short as possible. We strongly recommend our own Mission
or Cyrus loudspeaker cables.
The phono ground terminal (GND), on the rear panel, is provided for
connecting to the appropriate ground wire from your tonearm/turntable.
This will minimise the possibility of hum being induced in the phono
circuitry.
All the RCA phono sockets are colour-coded WHITE for the left and RED
for the right channel.
In the case of the Loudspeaker output terminals, RED is for positive and
BLACK is for negative.

IN CASE OF TROUBLE
CYRUS I AND CYRUS II
THE POWER L.E.D. DOES NOT ILLUMINATE AND THERE IS NO SOUND
Check that the unit is plugged into the mains socket, and the power,
switch is ON.
Check the mains fuse.
AS ABOVE BUT THERE IS SOUND FROM THE SPEAKERS
The LE.D. is faulty.
SOUND FROM ONE SPEAKER ONLY
Check the fault does not occur on other inputs by listening to other
sources. If the fault persists then continue with the following. If not, the
relevant source is at fault. Check input and loudspeaker connections of the
channel without sound.
Check loudspeaker fuse if any.
Interchange the loudspeaker connections between Left and Right channels.
Observe whether the fault changes over. If so then the amplifier has a
faulty channel. If the fault stays in the same channel, then the loudspeaker
is at fault.
NO SOUND FROM ANY SPEAKER
Check that the amplifier is On.
Check the sound on the other sources.
If problem persists then the internal fuses of the amplifier may have blown.
Refer the amplifier to your dealer.
HUM OR CRACKLING SOUND FROM ONE OR BOTH SPEAKERS
Check there are no faulty connections along the speaker cables and the
interconnect cables.
Check to make sure the turntable ground is connected to the GND terminal
on the rear panel.
Check that the turntable interconnect is not dressed next to any mains
leads.
MUSIC REPRODUCTION SOUNDS HOLLOW AND STRANGE
Check the speaker cables are connected to the amplifier and speakers
correctly.
If in Phono mode, check the cartridge has been wired correctly.
OPERATING INSTRUCTIONS
CYRUS I AMPLIFIER
1. Volume Control: Adjusts the power amplifier output level to the
Loudspeakers from zero to the maximum level.
2. Balance Control: Adjustment of the Balance Control knob swings the
output level to the left or right Loudspeaker by a maximum of 5 dB.
3. "Listen" Selector Switch: Selects the desired source for listening.
Starting from the fully clockwise position, the sources which may be
selected are as follows:
•Phono: Record Player; Moving Coil or Moving Magnet Cartridge.
•Mute: No source selected. May also be used to erase recorded tape.
•CD: Compact Disc Digital Audio Player.
•Tuner: FM/AM Hi- Fi Tuner.
•Video: Hi-Fi Video Recorder, a second Tape Deck (playback only).
•Tape: Tape Recorder used for record and playback (Including R-
DAT).
4. "Record" Selector Switch: Selects the desired source for recording via
the 'Tape-out" socket. Starting from the fully anti-clockwise position, the
sources which may be selected are identical to those on the "Listen"
Selector Switch.
Warning: Do not select 'Tape" position on both selector switches
simultaneously. This may cause feedback problems in the tape deck, if it is
in the record mode.
5. Power Switch: Switches the power amplifier section of the unit On (up)
and Off (down). The preamplifier section is powered as soon as the unit is
connected to the mains supply. This feature helps stabilize the operating
temperature of the preamplifier, and optimize the sound quality on switch-
on.
6. Red LE.D.: When the power switch is up (i.e the amplifier is on)"the red
LED. will light up to indicate fully operational status.
NOTE: It is important that the unit is unplugged from the mains supply if it
is unattended for any length of time. (Vacations, etc.)
REAR PANEL
All inputs plus the tape output are colour coded as follows: RED for the
right channel and WHITE for left channel.
7. Phono Input: Dedicated Input to accept the signal from a Record player.
8. MM/MC Switch: This should be set according to the type of cartridge
fitted to the Record player, i.e. MM (Moving Magnet), MC (Moving Coil).
9. CD: Dedicated Compact disc player input.
10. Tuner: Dedicated FM/AM Hi-Fi Tuner input.
11. Video: Input to be used with a Hi-Fi Video recorder or a second tape
deck.
12. Tape: Input suitable for use with a cassette deck, open reel tape deck,
or R-DAT recorder.
13. Tape Out: Carries the signal to be recorded. This should be connected
to the input of the tape recorder.
14. Loudspeaker Outputs: Loudspeakers are connected to the outputs of
the power amplifier at these terminals. These are colour-coded, RED for
positive and BLACK for negative. 4mm banana plugs are used to connect
loudspeaker cables at these points. A set is supplied with the unit.
15. IEC Mains Socket: The mains supply is connected to the unit via this
socket. It has an integral fuse which can only be removed after the mains
lead is disconnected.
