Introduction & Installation
INSTALLATION
ENGLISH
N.B. Circled numbers e.g. @ refer to items on the front and
rear panel diagrams.
O Check that your mains supply voltage agrees with the
voltage setting indicated on the rear panel of the unit.
■ If your mains supply voltage is different, consult your Arcam dealer.
MAINS SAFETY
This product is normally supplied with a moulded mains plug already fitted to the lead. If for any reason the plug needs to be removed, it must be disposed of immediateiy and securely, as it is a potential shock hazard when inserted into a mains socket.
Warning: This apparatus must be earthed.
NOTICE FOR U.K. OWNERS ONLY
If the plug is removed then the remaining lead must be
rewired as follows:
The blue wire must be connected to the terminal which
is coloured blue or marked with the letter N.
The brown wire must be connected to the terminal which is coloured brown or marked with the letter L.
The use of high quality interconnect cables in your system is essential for good sound quality. Contact your dealer or Arcam for recommendations.
If you are listening to an input and then switch to an unused (open circuit) input it may possible to still hear the original source but at a very low level. This is normal and is due to there being no equipment connected to that input.
® PROCESSOR/TAPE 2 OUT - Connect this output to the
input of your tape deck (usually labelled RECORD or IN) or to your AA/ processor's Tape or Line inputs.
© PROCESSOR/TAPE 2 IN - Connect this input to the

AN processor's Tape or Line outputs.
The green and yellow wire must be connected to the terminal which is coloured green and yellow, or marked with the letter E or the safety earth symbol.
When replacing the fuse in the supplied moulded mains plug, the integral fuse holder/cover must always be
refitted. Use a 5 amp fuse.
SAFETY STANDARD
■ This product has been designed to meet the I EC 65 international electrical safety standard.
MAINS SUPPLY CONNECTIONS
O Insert the lEC line socket of the mains lead fully into the
power inlet on the rear panel. Connect the other end to your mains supply.
CONNECTING YOUR SOURCE COMPONENTS
■ Using a suitable pair of interconnect cables, insert the red phono plugs into the sockets labelled 'R' and the other phono plugs into the sockets labelled 'L'.
All the line inputs (not PHONO) have the same sensitivity and may be used with equipment other than that labelled, if you need to do so.
© AN - Connect this input to the output of an audio-visual
product such as a VCR, Laserdisc or DVD player or
Nicam tuner.
© CD - Connect this input to the analogue outputs of your
CD player or DAC (digital to analogue convertor).
© AUX - Connect this input to the output of any unit with a
line level output, eg. tape deck, tuner etc.
PHONO OPTION - For use with a turntable. Please note: The phono inputs are on a separate plug in module which your Arcam dealer or distributor can supply and fit.
This module is compatible with most high output moving coil and moving magnet cartridges (MM) and low output
moving coil cartridges (MC).
MM or MC is selected via an internal switch. Your cartridge type should be specified when the module is fitted.
© MM - For connecting to a turntable fitted with a moving
magnet (MM) or high output moving coil cartridge.
© MC - For connecting to a turntable fitted with a low
output moving coil (MC) cartridge.
® GROUND TERMINAL - For connecting your turntable's
earth lead (if fitted).
PREAMP OUT CONNECTIONS
ENGLISH
® MAIN PREAMP OUTPUTS - Connect one set of the
PREAMP OUT sockets (left and right) to the input sockets of your power amplifier. The second set of sockets can be used to connect to a second power amplifier for biamping or to another power amplifier in a different room.
® ZONE 1 PREAMP OUTPUTS © ZONE 2 PREAMP OUTPUTS
The outputs available on these sockets are independently determined by the setting of the LISTEN (ZONE 1) and SEND (ZONE 2) selectors. They are fixed level unbalanced signals which can be used to connect to other integrated amplifiers in different rooms for simple multi room use. They are buffered and so are typically capable of driving up to 15 metres of high quality interconnect cable. The Zone outputs are not affected by the volume control or the remote control MUTE command (See also
OPERATION OF THE ALPHA 9C PREAMPLIFIER
® NORMAL/ AN READY SWITCH - (This switch is found
on the rear panel.) With the switch set to NORMAL the unit functions as a
standard amplifier. For use with an AN decoder with its
own volume control, such as the Arcam Xeta 2, set the
switch to ‘AN READY'. This bypasses the Alpha 9C's
volume control when 'PROCESSOR/TAPE 2' input is selected, to provide a fixed gain stereo preamplifier. The volume control and MUTE cannot be operated by the remote control handset in this situation.
© VOLUME - Simultaneously adjusts the volume level of
the main preamp outputs (®) and headphones.
The VOLUME control is motorised and can be controlled remotely with the supplied remote control handset (see Remote Control Functions for more details).
Note: With the volume at minimum it may still be
possible to hear music very faintly. This is normal.
© PROCESSOR/TAPE 2 - This is a tape loop which allows
you to monitor a recording made on a 3 head cassette deck. It can also be used to enable line inputs to be sent to an external surround decoder such as the Arcam Xeta 2 for processing, before being routed back to the amplifier.
For playback from a cassette deck or to reconnect the
output from an AN processor attached to TAPE 2 press
the button in. With the button out the ‘loop’ is taken out of circuit, so that the input signal chosen with the LISTEN selector is
routed through the amplifier.
Note: PROCESSOR/TAPE 2 is not remote controllable.
© DIRECT - When this button is pushed in it bypasses the
bass, treble and balance controls. This affects all inputs and will generally give a small improvement in sound quality.
® BASS - Rotate clockwise to boost the bass response
and anti-clockwise to cut the bass response. For a flat response leave in the central 'click' position.
CAUTION: Do not set the switch to A/V READY if you
have a cassette deck connected to the PROCESSOR/
TAPE 2 input.
This will bypass the volume control when you push the
PROCESSOR/ TAPE 2 button in and send the signal straight to your power amplifiers. This could give an extremely high sound output sufficient to damage your loudspeakers.
© LISTEN/ZONE 1 SELECTOR - Selects the input you
wish to listen to. This signal also goes to the TAPE 2 output sockets for recording on to a cassette deck or for external processing and also to the ZONE 1 preamp out sockets. The selector can also be operated by remote control. (See Remote Control Functions).
© SEND TAPE 1/ZONE 2 SELECTOR - Selects the input
you wish to record onto TAPE 1. This operates independently of the LISTEN function. Additionally this switch can also be used as a simple ‘second zone’ selector, routing a chosen source signal, via the ZONE 2 preamp out sockets, to a second integrated amplifier operating in another room in the house.
Note: The ZONE 1 & ZONE 2 preamp outputs are not controlled by the volume control but they can be muted via the MUTE button on the remote handset or by use of the front panel ZONE 1 / ZONE 2 switches ©, ® .
© TREBLE - Rotate clockwise to boost the treble response
and anti-clockwise to cut the treble response. For a flat
response leave in the central 'click' position.
The range of the tone controls has been deliberately limited to approximately +/- 6dB at the frequency
extremes.
© BALANCE - Rotate clockwise or anti-clockwise to move
the position of the stereo image. This may be necessary
if it is not possible to sit centrally between the speakers. In normal use leave in the central 'click' position.
© ZONE 1 - Push the button in to activate the ZONE 1
preamp out sockets. With the button in the out position the ZONE 1 preamp out sockets are muted.
® ZONE 2 - Push the button in to activate the ZONE 2
preamp out sockets. With the button in the out position the ZONE 2 preamp out sockets are muted.
© HEADPHONES SOCKET - Accepts headphones rated
between 8 ohms and 2k ohms fitted with a 6.3mm stereo jack plug. If your headphones are fitted with a different plug contact your dealer for a suitable adaptor.
If you wish to listen on headphones only use the remote handset MUTE button to mute the main preamp out
sockets.
ENGLISH
NB:lf you now wish to adjust the volume you need to do this manually as use of the volume buttons on the remote will un-mute the preamp outputs and allow signal to go to your power amps again. Alternatively you may be able to switch off the speakers connected to your power amplifier.
The ZONE 1 and ZONE 2 outputs will remain live and can be switched off with use of the front panel ZONE buttons.
The headphone socket is always switched on, irrespective of the positions of switches © and ® or the remote control MUTE function.
m
POWER - Switches the unit on and off.
© POWER LED - The LED above the POWER switch will
initially glow amber. After a few seconds, it will glow green. When the LED glows amber, the preamp out sockets are disconnected . The power led will also glow amber if the unit has been muted by use of the remote.
® REMOTE RECEIVER - The remote receiver is behind
the badge in the top left hand corner of the unit. Ensure the remote receiver is not obscured or commands from the remote control handset will not be received.
TAPE RECORDING
Both sets of tape sockets (TAPE 1 and TAPE 2) are identical in sensitivity and suitable for use with almost any type of recorder (cassette, hi-fi VCR, reel to reel, MD, etc.)
RECORDING (TAPE 1)
Use the SEND selector © to route the required signal to a cassette deck connected to the TAPE 1 RECORD OUT sockets ®. Set your tape recorder into its recording mode and the selected input will be recorded. Selecting the same input with the LISTEN selector will not affect the signal sent out to the recorder and will now enable you to listen to the signal being recorded.
If your tape recorder is a 3 head design, this will allow A-B monitoring of the actual recording while it is taking place. Switching the LISTEN switch between the original source and TAPE 1 during recording will then enable you to make a true ‘before’ and ‘after’ (A-B) comparison. You may listen to another input whilst recording on TAPE 1 by use of the LISTEN selector.
■ RECORDING (TAPE 2)
Use the LISTEN selector © to route the required signal to a cassette deck connected to the TAPE 2 RECORD
OUT sockets ©
Set your tape recorder into its recording mode and the
selected input will be recorded.
To monitor the recording push the PROCESSOR/ TAPE 2 button in. If your tape recorder is a 3 head design, this will allow A-B monitoring of the actual recording while it is taking place. You may record another input on to TAPE 1 whilst recording on TAPE 2 by use of the SEND selector.
« TAPE TO TAPE DUBBING: The Alpha 9C allows two
way tape dubbing (copying) from TAPE 1 to TAPE 2 or vice versa. For example, to copy from a recorder connected to the TAPE 2 sockets to a recorder connected to TAPE 1, first switch the SEND selector on the Alpha 9C to TAPE 2. This routes the TAPE 2 signal to TAPE 1's output. Then set the first tape recorder into its 'record' mode and the second to 'playback' mode to enable the transfer to take place. If you wish to monitor the transfer while it is taking place switch LISTEN to TAPE 1. To record from TAPE 1 to TAPE 2 set LISTEN to TAPE 1. It does not matter what position the SEND selector is in. To monitor push the PROCESSOR/ TAPE 2 button in.
REMOTE CONTROL FUNCTIONS
Your Alpha 9C preamplifier is supplied with the Arcam CR35 infra-red remote control handset, which has buttons to allow the simple operation of other products.
It is supplied with 2 AA batteries - ensure these are
inserted correctly.
The remote handset enables you to operate the LISTEN/ ZONE 1 SELECTOR, VOLUME and MUTE functions on the Alpha 90. It also allows you to control some basic functions of an Arcam or Philips based CD player (except the Alpha One CD player, which uses a different
remote control language) and a remote controlled tuner (such as the Alpha 8 tuner).
■ REMOTE MODE - The Alpha 9C is factory-set to enable the Arcam CR35 or Arcam CR200 System Remote automatically to synchronise the operation of any Arcam
CD player or transport, and remote control tuner with the LISTEN/ZONE 1 SELECTOR on the Alpha 9C, all at the touch of a single button.
For example, using the CR35 remote, press PLAY, and the CD player will start the disc and the LISTEN/ ZONE 1 switch of the Alpha 9C will select the CD input.
If automatic operation is not required it can be disabled
by your dealer by fitting an internal link. The
LISTEN/ZONE 1 selector switch can still be operated by
either remote control handset.
The MUTE button mutes the MAIN pre-amp outputs and the ZONE 1 & 2 preamp outputs. Both tape outputs and the headphone socket remain active. In MUTE mode the power LED will turn amber until mute is disabled by either pressing MUTE again or pressing the volume -/+ buttons on the handset.
Note: The ‘STBY’, 'DISP’ and 'VCR’ buttons on the CR35 have no effect on the Alpha 9C preamplifier. The ‘DVD’ button will select the ‘AUX’ input.
