Operating Instructions

Thank you for purchasing the 5350 amplifier. You are
now in possession of a State of the Art Integrated
Amplifier. The functions and operation of the 5350 and
Special Edition are exactly the same and are very sim-
ple. However, the following notes are provided to
explain all aspects of its design and use.

MAINS CONNECTION

When unpacking the amplifier please keep the packing
material in a safe place for possible future use. In the
pack there is a separate mains cable suitable for con-
necting to the mains supply in the country of use. The
IEC socket end of the cable should be firmly inserted
into the connector on the rear panel marked Mains
Input".

Remember. do not overload the mains wall socket with
too many plugs or adapters. The high quality perfor-
mance of the amplifier will be impaired if the electrical
supply to it is in poor condition. If in doubt, consult a
qualified electrician or your dealer.

The "Mains Input" connection is also fitted with a fuse,
specifically suited to the supply voltage of the country of
use. The correct value is clearly marked on the rear
panel next to the Mains Input,

Should it be necessary to replace the fuse, ensure that
you use the same type as specified on the rear panel,
Le.

5 x 20mm cartridge type: T 3.15 A surge resisting
for 220-240V 50H: AC, T 6.3 A surge resisting for
110-120V 60H: AC or an T BA surge resisting for
100V (Japan).

LOUDSPEAKER CONNECTIONS

The loudspeakers should be connected using a suitable pair of interconnects designed
specifically for audio use. Two pairs of screw terminals marked A allow for either bare wire
or spade lug connectors to be passed through the hole or around the bush. Tighten the ter-
minal fully after fitting the speaker wire. Please consult your dealer for advice if you are
unsure. Caution Shouting the speaker wire or connectors will damage your amplifier.

It is important to connect the loudspeakers to the loudspeaker terminals in the correct
phase. Cables are normally polarised with a line or a raised bump on the positive side. If
one channel is not connected in the same fashion as the other, a severe loss of bass per-
formance and a spreading of the stereo image will result.

A second set of terminals marked 3' allow the user to select from the rotary control in the
centre of the front panel, the option of having two pairs of speakers running separately, or
together. The options include speakers off, when using headphones, speakers A, speakers
B and speakersAand B together.

Caution It is not recommended to use loudspeakers of less than 49 resistance or more
than two pairs of 89 speakers running from the amplifier at one time. However, bi-wiring of
one pair of speakers, using the four terminal posts, can improve the sound of your system
(consult your dealer for more details).

.5. It is VERY IMPORTANT not to short the loudspeaker cables together when the other

ends are still connected to the amplifier, othenvise permanent damage can result. If it is
necessary to move or change the location of your loudspeakers, make sure that you
switch ofi the amplifier from the mains, or switch off the speakers from the selector first.

INPUT CONNECTION AND SWITCHING

On the 5350 all six line input circuits, including the tape input, are passive. It is possible to
make the pre-amp section active by removing the link PCB and replacing it with an active
gain circuit. An increase in sensitivity of between 3 - 6dBs will result. Askl your dealer.

The tape input is in a loop with the tape output, enabling you to record anything you can
hear, or in other words, Monitor recordings without interrupting the signal. The rotary
selector switch on the left-hand side of the amplifier is used to select and listen to any of the
desired inputs. The second rotary selector switch on the 5350, marked Record, allows you
to record any input independent ofthe input you are listening to.

As all the line input levels are the same, it is not necessary to use the precise inputs as
designated. You may, for example, plug a CD player into the Tuner input and obtain exactty
the same result or performance as the dedicated CD input. However, for added flexibility,
the first input on the 5350 can be used either for vinyl Disc or Auxiliary Line.

An optional low noise MM or MC Phono Amplifier Module is available, which replaces the
standard passive Link pcb, internally. Check with your dealer for more details if required.

Two U shapped metal links are plugged between the sockets on the rear panel, marked pre-
amp and power amp. They are intended to join the pre-amp to the power amp externally. lf
removed, the two circuits can be accessed separately. Do not loose these links, as the
amplifier will not work normally without them.

VOLUME LEVEL

The volume control, situated in the right hand side of the front panel, is used to alter the rel-
ative level of the sound output from the amplifier. It is important to realise that the volume
control only acts to reduce, or attenuate, the incoming signal to the power amplifier stage.
The maximum power of the amplifier is available only if the level of signal available from the
line level equipment is sufficient to drive it into clipping.

An active CreekAudio gain board may needed to increase the level as required (options
include +3dB, or +6dB . Consult your dealer if you feel you need more advice.

OPERATING THE 5350

Make sure that the unit is on a suitable table, shelf or Hi-Fi equipment cabinet. It is important to
allow adequate ventilation to the heatsink in the centre of the unit. Avoid obstruction of the ven-
tilation slots on the top and bottom of the amplifier. It may be necessary to place the amplifier
on the top of other equipment to allow for this.

Always have the volume control set at minimum (counter-clockwise) when switching on and
off, to avoid any sudden loud noises. Select the desired input on the rotary selector and
switch on the amplifier with the push button marked Power on the right hand side of the
front panel. Adjust the volume gentiy and settle down to listen.

Your 5350 amplifier is designed to give years of reliable use if used oorrectty. If you need
more assistance, it is always advisable to go back to the supplying dealer for his expert help.
If you are unfortunate enough to need service work to be carried out on your amplifier, it
should be returned to your dealer in the original packing material if possible.

REMOTE CONTROLLED VERSION (5350R 8t 5350SE)

The 5350R and 535OSE front panel controls function in exactly the same way as the stan-
dard 5350. The CreekAmplifier Remote Control handset allows the user to operate the vol-
ume control, input selection and mute by an infra-red (R05) link. The bottom three buttons
on the handset are for motorised volume up + down, plus mute functions. The buttons
marked 1 Phono to 6 Tape are for selecting the desired source via a motorised version of
the rotary input selector. Handset buttons 7, 8, 9 8. 0 are not used on the 5350.

When the 5350R or the 53508E are first switched on, the power LED will glow yellow until
the protection circuit confirms everything is OK. The LED will then turn green and, if select-
ed, the loudspeaker relays will click on. Volume changes will cause the Power LED to
flash green. Pressing the mute button will cause the LED to turn yellow. Pressing the but-
ton again or increasing the volume will un-mute the amp and the LED will turn green again.
Adjusting the volume downwards by remote will not un-mute the amp. Please note, muting
can only be cleared by the remote handset or by switching the amplifier off for 30 seconds
and back on again. If the amplifier stops working and the Power LED turns red, it indicates
a fault. Return the amplifier to the supplying dealer for inspection.

NJ. The 5350 is designed to work properly in normal domestic operating conditions.

However, the amplifier's performance may be seriously affected if sited near to, or in the
room with, a radio transmitter such as a mobile phone or CB radio rig, etc. Re-siting the
5350 or the radio will normalise the situation.
