come per tutte le unità elettroniche è necessario osservare alcune precauzioni:
Badate as tutte le avvertenza indicate e riportate dietro all'unità.
Collefare l'A3.2 CR pre-amplifier solamente a prese di rete che hanno la stessa tensione d'uso
riportata sul retro dell'unità.
Assicurarsi sempre che quando si collegana o scollegana i vostri apparecchi audio l'alimentazione
sia spenta e la spina staccata dalla presa.
Porre il cavo di alimentazione ed i cavi di inter / connessione dove non vengano schiacciati comminando
e/o intrappolati/schiacciati da oggetti posti loro sopra.
Non usare vicino ad acqua, o non porre contenitori d'acqua sull'unità, come per esempio,vasi di fiori
o vasi di piante e sottovasi. Se acqua dovesse entrare, immediatamente staccare l'interuttore generale
e la spina dalla presa a muro ed informate il vostro rivenditore, che dovrà controllare l'unità prima
di usarla nuovamente L'entrata di liquido all'interno è pericoloso, e può causare elettrico shock o
rischi di incendio.
Non porre l'unità vicino a sorgenti di calore qyuali ad es. caloriferi, raggi solari o altri apparecchi.
L'involucro di questo preamp e dei finali potrebbediventare/diventa caldo . Porre l'unità in un'area ben
ventilata e non toccar la porzioni coinvolte dal calore (quali ad es. alette di raffreddamento) .
Non rimuovere i coperchio o tentare di accedere all'interno. All'intenro non vi sono parti che debbono
essere raggiunte dall'utilizzatore. Se necessitate di assistenza rivolgetevi solo a centri pecializzati.

di pulizia - questi potrebbero danneggiare la superficie.
L'elettronica in moderni equipaggiamenti hi-fi è complessa e può essere afflitta negativamente o dan-
neggiata dai fulmini . Per proteggere il vostro sistema audio durante temporali con fulmini, rimuovere
la spina di rete e scollegare ogni cavo aeriale.
Se viene richiesta assistenza dopo-vendita, fornite al rivenditore il numero di matricola, lo scontrino
fiscale ed una descrizione del difetto.

TELECOMANDO
TELECOMANDO
The blue buttons on the remote control enable main functions of the preamplifier 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 CR Pre-amplifier.
Equivalent buttons on the remote handset have the same functions as the those on the front
panel of the unit. Some operations are only available via the handset.
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 pre-amplifier, without visual obstruc-
tion between them.
Pressing the volume-up or -down buttons on the remote handset will advance the motorised
volume control in the required direction.
Pressing the MUTE button mutes audio output from the LINE-OUT sockets, but has no effect
on the TAPE OUT sockets for recording. To show that the line output is muted, the blue LED
in the volume control knob goes out. Press the MUTE button again to cancel mute function,
and the blue knob 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 and output connections should be
made with the mains power switched OFF.
INPUT CONNECTIONS
The A3.2 CR pre-amplifier has one pair of
phono inputs, which can be used either for
moving magnet (MM) or moving coil
(MC) pickups.
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.
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.
The A3.2 CR Pre also has five “line level”
inputs which are electrically identical, and
therefore suitable for use with any source
component having an output of at least
300mV. Input sockets on the rear panel are
marked CD, TUNER, AUXILLIARY 1,
AUXILLIARY 2, and TAPE, to corre-
spond with function buttons on the front
panel.
Connect the left and right outputs from
your CD player, tuner, tape deck or phono/
record deck to the appropriate RCA input
sockets on the back panel.
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
RFI suppression. Various lengths are
available in the Nu-Vista interconnect
range. Please contact your local dealer for
more information.
PRE-AMPLIFIER OUTPUT
Left and right audio outputs are provided
from RCA sockets on the back panel,
which are controlled by the volume adjust-
ment.
TAPE RECORDER CONNECTION
The pre-amplifier has a single tape circuit
with facilities for off-tape monitoring with
suitable 3-head tape decks (see page 7).
Connection of your tape recorder to the
A3.2 CR Pre should be as follows:
The tape deck's left and right line outputs
are routed to the pre-amplifier's TAPE
(input) sockets, and the tape deck's line
inputs are connected to the A3.2 CR's
TAPE RECORD (output) sockets.
BEFORE SWITCHING ON . . . . .
Plug the accessory IEC mains lead into the
rear panel socket, then the other end into a
convenient wall outlet.
Turn the volume control on the front panel
to minimum (anticlockwise).

STARTING . . . .
Press the power button on the A3.2 CR pre-
amplifier. The red power LED on the front
panel will light confirming that the unit is
ready for use. However, for the first five
seconds, sound from your speakers will be
muted, and the blue LED in the volume
control will not be lit. During this initial
period, the seven blue function LEDs will
flash in sequence.
Unless using your pre-amplifier for off-tape
monitoring (see paragraph opposite )
ensure that the TAPE MONITORbutton
has not been pressed accidently, as other-
wise no sound will be heard through the
speakers.
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.
TAPE RECORDING
To record, simply select the required source
with the input selector button on the front
panel. This source will now be routed to
the A3.2 Pre’s TAPE RECORD output
sockets for recording by the external tape
deck.
You will also be able to hear the selected
source through the loudspeakers.
Note - adjustment of the volume control has
no effect on the recording level.

OPERATION
OFF TAPE MONITORING
In conjunction with a 3-head cassette deck,
off-tape monitoring allows the user to com-
pare the 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. The
TAPE MONITOR button on the front
panel can now be used to switch between
the source sound and its recorded version.
The blue LED just above the tape monitor
button indicates that the tape monitor func-
tion is operating.
Note that the recorded sound is selected
when this LED is lit. On some 3-head tape
decks there is an additional 'tape/source'
switch which must be in the 'tape' position
for the above arrangement to work.
If in doubt, please refer to your tape deck
operating manual.

TROUBLESHOOTING
Basic problem solving with a pre-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:
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 CR Pre-amplifier yourself,
as this will invalidate the guarantee.
