Designed and made in the UK.

Thank you for purchasing the 5350SE. You are now in possession of a State of the Art Integrated
Amplifier. The functions and operation of the 5350 Special Edition are very simple. 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 connecting 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 adaptors. The high quality
performance 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, i.e. 5 x 20mm cartridge type:

T 3.15 A surge resisting for 220-240V 50Hz AC,
T 6.3 A surge resisting for 110-120V 60Hz AC
T 8A surge resisting for 100V (Japan).

VOLUME LEVEL

The volume control, situated in the right hand side of the front panel, is used to alter the relative 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 to clipping.

The volume control is necessary to adjust the level from one piece of equipment to another. It does not
increase the power of the amplifier and if it is found necessary to have the volume control set to a posi­tion which is considered to be high, before the desired level of volume is obtained, it does not neces­sarily mean that the amplifier is having to work "flat-out". The selector switch on the gain board may
need to be set to a different level setting to increase the level as required (options include +3dB, +6dB
and +10dB). Consult your dealer if you feel you need more advice.

OPERATING THE 5350SE

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 ventilation 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 gently and settle down to listen.

Your 5350SE amplifier is designed to give you years of reliable use. 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 CONTROL

The Creek Amplifier Remote Control handset allows the user to operate the volume control, input selec­tion and mute by an infra-red (RC5) link. The up/down buttons in the centre of the handset are for
motorised volume up + down, the large single button in the centre is the mute button. Source selection
buttons are the white ones at the bottom left.

When the 5350SE is 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 selected, 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 button 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 pressing the amplifier power
switch off for 10 seconds and 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.

N.B. The 5350SE 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 5350SE or
the radio will normalise the situation.

LOUDSPEAKER CONNECTIONS

The loudspeakers should be connected using a suitable pair of cables 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 terminal fully after fitting the speaker wire.
Please consult your dealer for advice if you are unsure.

It is very 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 performance and a spreading of the
stereo image will result.

A second set of terminals marked 'B' 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 plua speakers A and B
together.

It is not recommended to use loudspeakers of less than 4W resistance or more than two pairs of 8W
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).

N.B. It is very important not to short the loudspeaker cables together when the other ends are
still connected to the amplifier, otherwise permanent damage can result. If it is necessary to
move or change the location of your loudspeakers, make sure that you switch off the amplifier
from the mains first.

INPUT CONNECTION AND SWITCHING

On the 5350SE all six line inputs, including the tape input, have some gain (active circuitry), which can
if required, be increased or decreased by changing the setting of the selector switch on the internal
plug-in gain PCB. Consult your dealer if you feel you need more advice. It is also possible to make the
pre-amp section passive by removing the gain PCB and replacing it with a passive link PCB. A reduced
sensitivity will result.

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 5350SE, marked Record, allows you to record any input independent of the 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 exactly the same result or per­formance as the dedicated CD input. However, for added flexibility, the first input on the 5350SE 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.
