Green Power GP-120 Integrated Amplifier
Operating Instructions
Thank you for purchasing the Green Power GP-120 Integrated Amplifier. You are now in possession of an integrated amplifier designed to give
you years of reliable use. Flexibility in design makes possible this state-of-art amplifier to work in conjunction with an external device as a
pre-amplifier or a power amplifier as desired. Functions and operation of the Green Power GP-120 are very simple. However, the
following notes are provided to explain all aspects of its design and use. If you need more assistance, it is always advisable to go back to
the supplying dealer for help. When service work is necessary, the amplifier should be returned to your dealer in the original packing
material if possible.
The Green Power GP-120 amplifier is designed to work properly in normal domestic operating conditions. However, the amplifier's
performance may be affected if sited near to a radio transmitter such as a mobile phone etc. Re-locating the amplifier or the radio
transmitter will normalize the situation.
MAINS CONNECTION
After unpacking the Green Power GP-120 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 "AC".
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. The "AC"
connection is also fitted with a fuse, specifically suited to the supply voltage of the country of use. Should it be
necessary to replace the mains fuse, ensure that you use the one equivalent to what given in the container, i.e. 5
x 20mm size. Unscrew cap of the container to replace fuse. After change, replace cap and screw tight.

POWER CONSUMPTION
It is appreciated by Hi-Fi enthusiasts that leaving equipment powered-up continuously can improve performance of an amplifier. GP-
120 amplifier features a capability of maximizing output at a minimal consumption of energy. However, improvement in
sound quality comes at the expense of power consumption from the mains which will not only cost more but will also reduce the working
life of the amplifier. We recommend that if the equipment is not being used for an extended period of time, switch it off from the mains switch
on the rear panel. Normal performance can be achieved in a short period of time.
SET-UP
To obtain the best results, make sure that the Green Power GP-120 amplifier is placed on a stable shelf or Hi-Fi equipment rack. It is
important to allow adequate ventilation to the amplifier. As the amplifier itself dissipates less heat in operation, large sized heat
conducting fins are not installed. As usual, it will still necessary to place the amplifier on its own shelf or the top of other equipment to
allow for this so that the amplifier could perform at optimal condition. Always have the volume control set at minimum (counter-clockwise)
when switching on and off so as to avoid any sudden loud noises.
