LOUDSPEAKER CONNECTIONS
The loudspeakers should be connected using a suitable pair of cables designed specifically for audio use. The screw terminals allow for either bare wire or spade 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. Positive and negative sides of the cable are normally polarised with a
line or a raised bump on the positive side. If one channel is not connected in the
same way as the other, a severe loss of bass performance and a spreading of the
stereo image will result.
It is not recommended to use loudspeakers of less than 4
Ω resistance or more than
two pairs of 8Ω 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 working 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
All the line inputs on the amplifier are passive as standard and have a sensitivity in the
region of 350mV's for maximum power output. 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.
A button on the front panel, marked Tape Monitor, should be in the out position for
normal use and pressed in for monitoring from tape.
The rotary selector switch on the left-hand side of the amplifier is used to select any of
the desired inputs. 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 4330 is for use as vinyl Disc
or Auxiliary Line, and an optional low noise MM or MC phono amplifier module is
available, which replaces the standard passive Link PCB, internally.
A Gain Stage module (IA Gain) is also available as an option to increase the sensitivity of the pre-amp section when the standard passive pre-amp is not sufficient. Check
with your dealer for more details.
VOLUME LEVEL
The volume control, situated in the middle of the front panel, should be 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 (when the volume control is fully clockwise) if the level of signal available from the line level equipment is sufficient to drive it to clipping; this will be in the region of 350mV's.
The volume control is necessary to balance 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 optional Gain Stage module may be needed to
increase the level as required. Consult your dealer if you feel you need more advice.
OPERATING THE 4330
Make sure that the unit is on a suitable table 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 cover. 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 thumps or sudden loud noises. Select the desired input on the
rotary selector and switch the amplifier on 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 4330 amplifier is designed to give you years of reliable use. However, it is necessary to take care of your possession, so never overheat it or short-out the speaker
connections. If an adjustment is needed to the plug-in MM circuitry, it is always advisable to return it 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 VERSION (4330R)
The 4330 remote version works in exactly the same way as the standard but has the
capability of remote operation of the volume control and mute. The Creek amplifier
remote handset has three buttons for these functions at the bottom. The remaining
input selection buttons are for use on other Creek products and do not control anything
on the 4330. The power LED will change colour from green to red when muted.
Volume changes will cause the LED to flash yellow. Muting will be cleared if the volume is moved up but not down. Only the remote handset can clear the mute, or
switching the 4330 off for 10 secs and on again . The 4330 remote circuit is designed
to go into sleep mode when not in use and the LED will revert to green.
N.B.
The 4330 is designed to work properly in normal domestic operating conditions. However, the amplifiers 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 4330, or the radio, will normalise the situation.
