GENERAL ADVICE
INSTALLATION PRECAUTIONS and USER INFORMATION
Your new A3.2 Integrated amplifier is designed and built to provide trouble-free performance,
but as with all electronic devices it is necessary to observe a few precautions:
Heed all warnings shown on the back of the product.
Only connect the A3.2 Integrated amplifier to a mains outlet having the same voltage as
marked at the back of the unit.
Always ensure that when disconnecting and reconnecting your audio equipment the mains
supply is switched off.
Position the mains lead and signal interconnects where they are not likely to be walked on or
trapped by items placed on them.
Do not use near water, or place water-filled containers on the amplifier, for example, flower
vases or potted plants. If water does spill inside, immediately pull out the mains plug from
the wall socket and inform your dealer, who should then check the unit before further use.
Entry of liquid into the amplifier is dangerous, and may cause electric shock or fire hazard.
Do not place the unit near heat sources such as radiators, direct sunlight or other equipment.
The case of this amplifier can run at high temperatures - operate the unit in a well ventilated
area, and do not touch the cabinet sides or top after periods of use at high output power.
Do not remove covers or try to gain access to the inside. There are no internal user adjust-
ments. Refer all service work to an authorised Musical Fidelity agent.
NOTE: Unauthorised opening of the equipment will invalidate any warranty claims.
There are fuses inside the A3.2 amplifier. In the unlikely event that one blows, refer the unit to
your audio dealer. Do NOT try to replace the fuse yourself as this will invalidate the warranty.
Dust regularly with a soft duster or soft brush, but be careful when using cleaning or polishing
agents - they may harm the surface finish.
The electronics in modern hi-fi equipment is complex and may, therefore, be adversely affected
or damaged by lightning. For protection of your audio system during electrical storms, remove
the mains plugs and disconnect any aerial lead.
If after-sales service is required, to help your dealer identify the A3.2 Integrated amplifier
please quote the serial number located on the rear panel of the unit.
RADIO FREQUENCY INTERFERENCE (R.F.I)
This product has been tested to ensure that its operation is not adversely affected by normal
background levels of R.F.I., and that it does not itself generate excessive amounts of interfer-
ence. However, if a problem persists, please contact your Musical Fidelity agent.

REMOTE CONTROL
REMOTE CONTROL
The blue buttons on the remote control enable main functions of the amplifier to be operated
from a convenient distance. Remaining buttons on this universal handset are for use with other
Musical Fidelity products, and have no effect on the A3.2 Integrated amplifier.
Equivalent buttons on the remote handset have the same functions as those on the front panel of
the unit.
As the remote control uses an invisible infra-red light beam, the transmitter must be pointed
directly towards the receiver window on the front of the amplifier, without visual obstruction
between them.
Pressing the volume-up or -down buttons on the remote handset will advance the motorised
volume control in the required direction.
The MUTE button mutes the SPEAKER output and PRE-OUT sockets. To show that the
amplifier is muted, the blue LED in the volume control knob goes out. Press the MUTE button
again to cancel mute function, and the blue LED will light again.
If the range of the remote control greatly decreases, replace the batteries with new ones.
Do not mix old and new batteries - two are required, type SUM-4, AAA or LR03.

CONNECTIONS
All input, output and power connections
should be made with the mains power
switched OFF.
Various lengths are available in the Nu-
Vista interconnect range. Please contact
your local dealer for more information.
INPUT CONNECTIONS
OUTPUT CONNECTIONS
The A3.2 Integrated amplifier has one pair
of phono inputs, which can be used either
for moving magnet (MM) or moving coil
(MC) pickups.
Connect your loudspeakers to the terminals
on the back panel marked as LEFT and
RIGHT SPEAKER outputs.
PRE-AMPLIFIER OUTPUT
The phono input sensitivity requirement
can be changed from MM to MC by press-
ing the push-button switch located on the
rear panel.
Important - Do not operate the MM/MC
switch with the volume control turned up.
The A3.2 Integrated amplifier has its pre-
amplifier output available from RCA sock-
ets on the back panel marked PRE-OUT,
and is controlled by the volume adjustment.
Some turntable/pickup arm combinations
are fitted with an extra wire for chassis
earthing. This should be connected to the
earth terminal on the back panel.
This is to allow “bi-amplification” using
suitable external amplifiers and crossover
networks to power the speaker drive com-
ponents separately, giving noticeable
improvement in clarity, imaging and bass
weight.
The A3.2 amplifier also has five “line
level” inputs which are electrically identi-
cal, and therefore suitable for use with any
source component having an output of at
least 300mV. The sockets on the rear
panel are marked CD, TUNER, AUXIL-
LIARY 1, AUXILLIARY 2, and TAPE,
to correspond with function buttons on the
front panel.
In this arrangement, typically the A3.2’s
speaker outputs are used to drive the speak-
er’s “tweeter” (high audio frequencies), and
an external stereo amplifier drives the
“woofer” (low frequencies).
The A3.2’s PRE OUT RCA sockets would
therefore be connected to the input of the
external “woofer” amplifier in this exam-
ple.
Connect the left and right outputs from
your CD player, tuner or phono/record
deck to the appropriate RCA input sockets
on the back panel.
If you are in doubt about bi-amplification,
please contact your dealer for advice.
Connect the A3.2’s TAPE input sockets to
the line output of your tape recorder, and
A3.2’s TAPE RECORD output sockets to
the line input sockets of the tape deck.
BEFORE SWITCHING ON
Plug the accessory IEC mains lead into the
rear panel socket, then the other end into a
wall outlet.
For the best results we recommend using
either Musical Fidelity X-LINX "no-non-
sense" cables for this connection or the
highly rated Nu-Vista leads with integral
Turn the volume control on the front panel
to minimum (anticlockwise).

OPERATION
STARTING . . . .
OFF TAPE MONITORING
Press the POWER button on the A3.2
amplifier - the red power LED on the front
panel will light indicating that the unit is
ready for use. However, for about five sec-
onds no sound will be heard from your
speakers, and the blue LED on the volume
knob will not be lit, confirming initial mute
action.
The A3.2 amplifier has a single tape circuit
with facilities for off-tape monitoring with
3-head tape decks.
In conjunction with a 3-head cassette deck,
off-tape monitoring allows the user to com-
pare recorded sound with the original whilst
a recording is being made. To do this, first
select the required source in the normal way
and start recording.
Unless using your amplifier for off-tape
monitoring (see paragraph opposite
)
ensure that the TAPE MONITOR button
has not been pressed accidently, as other-
wise no sound will be heard through the
speakers.
The MONITOR button on the front panel
can now be used to switch between the orig-
inal source sound and the recorded version,
allowing direct comparison. The blue LED
just above the monitor button is lit when the
tape monitor function is operating, confirm-
ing that the recorded sound is selected.
Select the required audio input source by
pressing an appropriate function button on
the front panel or remote control, and adjust
the volume control to obtain the preferred
sound level.
On some 3-head tape decks there is an addi-
tional ‘tape/source’ switch, which must be in
the ‘tape’ position for the above to work.
TAPE RECORDING
If in doubt, please refer to your tape deck
operating manual.
To record, simply select the required source
with the input selector button on the front
panel or remote control. This source will
now be routed to the A3.2’s TAPE
RECORD output for recording by the
external tape deck. You will also be able to
hear the selected source through the loud-
speakers.
Note - adjustment of the volume control has
no effect on the recording level.

TROUBLESHOOTING
Basic problem-solving with an amplifier is similar to troubleshooting any other electrical or
electronic equipment. Always check the most obvious possible causes first. To give you a few
ideas of what to look for, check the following:
Problem
Possible Cause
Remedy
No power when POWER
button is pressed
Mains plug not inserted
fully into rear socket
Plug in securely
No sound
Tape monitor function has
been selected
Switch off tape monitor
Wrong connections between
input sources and the A3.2
amplifier
Check audio input lead
connections
Speakers not connected, or
incorrectly wired
Check speaker cables
Sound is not precise, lacking Speakers are connected out of
Ensure speakers are
connected correctly
in bass and stereo image
phase, i.e., connections to one
speaker (+ and -) are reversed
If none of these actions effect a cure, please contact your dealer, or an authorised Musical
Fidelity service agent. Remember, never open the case of the A3.2 Integrated amplifier your-
self, as this will invalidate the guarantee.
