ENCLOSED DOCUMENT: CERTIFICATE OF WARRANTY
Our amplifiers are modular in design. The metal chassis is very rigid
and the interior design provides easy access to the electronic circuits.
Fully independent safety circuits protect the amplifier in the event of a
short circuit of the loudspeaker output, abnormal increases in temper-
ature and/or excessive amplifier consumption.
The HD Series amplifiers offer high dynamic performance with moder-
ate average energy consumption, as well as good damping factor, which
results in clean response to transients and high quality playback.
The power modules are integrated in a tunnel-shaped own developed
heat sink, which combines high dissipation power with an excellent
thermal inertia, thanks to the high extraction effectiveness of the in-
corporated fans.
