In view of the fact that the requirements of audio professionals
are increasingly greater, we would like to thank you for choosing
a MASTER AUDIO product. At AMATE ELECTROACÚSTICA, we
have incorporated the highest technology into our products with
the conviction that what you have purchased will give you an op-
timum performance and operation, however 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 metal chassis is very
rigid and the interior design provides easy access to the electron-
ic circuits. Fully independent safety circuits protect the amplifier
in the event of a short circuit of the loudspeaker output, abnormal
increases in temperature and/or excessive amplifier consump-
tion.
2. Front panel features
- On-Off switch (1) Led ON.
- Volume potentiometers (Gain) (2)

INDEX
The HD Series amplifiers offer high dynamic performance with
moderate average energy consumption, as well as good damp-
ing factor, which results in clean response to transients and high
quality playback.
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 effec-
tiveness of the incorporated fans.
