A120
Dear Customer,
Thank you for purchasing a A120 Integrated amplifier.
This unit provides ease of use and sonics of the highest quality. Please pay close attention to this instruction manual, and
read it fully before attempting to operate. It is designed to ensure that you maximise your pleasure of A120 and familiarise
you with its many unique functions.
CHECKING
CONNECTIONS
Check that the carton has no damage. Should you have any
doubt about its condition, please do not hesitate to contact your
dealer.
Having verified that the mains voltage indicated on the rear of the
unit corresponds to the local power supply mains voltage and that
the ON/OFF switch is on OFF position, connect the mains leads
provided to the rear the unit and to the wall socket.
Connect the Stereo Interconnect cables from the rear of all your
sources to the corresponding inputs on A120.
If you have a multi-channel source ( SACD, DVD…), A120 gives
you the possilbility to use it as power amplifier for the Front
channels. You will then need a 3 channel power amplfier like the
Minium T120 to feed Center and Surround left and right channels.
Connect the multi-channel source using the Multi-channel Input
and Output located at the back og A120. Very carefullly follow the
input and output pattern.
Connect your loudspeaker cables between AMP and your
loudspeakers payind attention to polarity.
We would like to emphasize that the Left speaker positive
signal is facing downward when the Right speaker positive
signal is facing upward..
DEBALLAGE
Very carefully remove the unit from the box, taking care to
preserve all the packing material. It is good practice to put the
carton and its contents into an outer plastic bag and deposit it
somewhere safe and dry. In the unlikely event that your unit
needs to be sent back to either your dealer or distributor, it must
be sent in the original packing material. Failure to observe this
will invalidate your warranty.
ACCESSORIES
Upon opening the carton you should find the following:
- Mains Lead.
MAINS VOLTAGE
- Check that the mains voltage indicated on both the carton and
the rear of the unit correspond to the local power supply
- If you are in any doubt, consult your dealer.
The very high quality speaker terminals accept different type of
connections like bananas, or stripped up to 10mm² speaker wire .
It is important to use quality speaker cable to get the maximum
out of A120.
INSTALLATION
POWER UP
In order to obtain the maximum performance of A120, it is
important to follow the installation instructions.
Wherever possible, we recommend that A120 is installed in an

WARNING!
If for aesthetic or ease of use reasons, you choose to stack the
units, it is imperative that you place A120 on the top. Never place
any unit on top of A120. We recommend that you provide a space
of at least 30cm above A120 in order to ensure adequate
ventilation.
