The HSD Range of Professional Power Amplifiers
At Verus Audio the design team have
employed only the finest high tolerance
audiophile grade components in the
Hi-Side drive MOS FET circuitry, with its sonic excellence and proven
reliability gives you the best sound possible. The active clip control ensures a
completely clean sound at any level, reducing overload distortion and allowing
more headroom. For installation or use in any environment these units are
unbeatable. There is an HSD amplifier in the range to suit your venue, whether
operating in dual or bridge mode they are easy to install and maintain.
There are three amplifiers in the
HSD series, with output power ranging from 1000, 1500
and 2000 watts rms into 4 ohms. All have generous power
supplies with high efficiency toroidal transformer and massive amounts of
capacitance (storage power). Enabling these models unrivalled control over the
entire frequency range. They are equally at home to driving extremely low bass,
superbly defined and articulate mid range or crystal clear high’s. The unit’s
power is capable of delivering musical transients far in excess of the
amplifiers rated output without distortion and any risk of driving the speakers
with a clipped signal. All three models are housed in purpose built 2U chassis
and are supplied as standard with vertical led level metering. There are also
options for horizontal led or analogue VU metering. Remote level and turn on or
standby control, are to order only.

| Overall Protection |
-
Soft start with surge protection which limits in rush current to < 5 Amps
-
Time delayed output connection to speaker loads
-
Auto thermal and manual control for 2 speed fan
-
Separate channel thermal safety shutdown, in case of continuous over driving.
Channels will not re-set on temp drop, thus eliminating toggling which could normally
result in damaging speakers
-
Shutdown sensing circuit which monitors for improper load conditions on the separate
channel outputs.

| Enclosure |
The case has been specifically
designed around the standard 2U rack mounting specification to give maximum power for the
smallest space possible without compromising quality or functionality. The cases are
finished in an attractive mottled black powder paint, all except the sides, which are
anodised.
