In view of the fact that the requirements of audio professionals are
increasingly greater, we would like to thank you for choosing a AMATE
AUDIO product. At Amate Audio S.L., we have incorporated the highest
technology into our products with the conviction that what you have
purchased will give you an optimum performance and operation, how-
ever adverse the working conditions to which you may submit it.
In order to achieve the best performance and correct operation, it is
important that you read the instruction manual carefully before making
any connections.
In addition, we recommend that you read the Warranty Certificate
enclosed with this Manual in case you may observe any anomaly prior to
or immediately after start up, and how to proceed on each case.
1. General features
Our amplifiers are modular in design. The rigid metal chassis pro-
vides easy access to the electronic circuits. Fully independent safety
circuits protect the amplifier in the event of a short circuit of the loud-
speaker output, abnormal increases in temperature and/or excessive
amplifier consumption.
The HD Series amplifiers offer high dynamic performance with
moderate average energy consumption, as well as good damping factor,
which results in clean response to transients and high quality playback.
2. Front panel features

1) Power Switch - On-Off switch with Led
2) Volume Controls - Potentiometers to independently control the output
level for each channel.
3) VU-Meters - Independent output signal indicators, with Leds for different
relative levels: -36dB, -24dB & -12dB.

ENCLOSED DOCUMENT: CERTIFICATE OF WARRANTY
The power modules are integrated in a tunnel-shaped own de-
veloped heat sink, which combines high dissipation power with an
excellent thermal inertia, thanks to the high extraction effectiveness
of the incorporated fans.

4) Limiter - Led indicating the operation start of the anti-clipping or limiter
systems.
5) Protection - Led indicating the operation of any of the protection system
of one or both channels. At power up normally it will turn ON momentarily.
If it does not turn OFF, indicates a problem of malfunction of the amplifier.
6) Bridge mode - Led indicating the bridge mode.
7) Parallel mode - Led indicating parallel mode.
8) Cooling outs - Forced air output for temperature regulation.
9) Panel screws - Detach (no tools needed) to access the internal panel.
10) Limiter adjust - Easy adjustment for the limiter threshold of each output.
For more information see Section "Limiter Adjustment".
