weight Some amplifiers are just
designed heavy, because it takes more time and effort and
money to design them light! At ARX, weve invested in
extensive R & D to solve the weight problem. Speaker
Protection Weve also done
intensive research into amplifier protection, in order to
design a system that really does work in the real
world. Thus the AmbiDrive has relay switched protection
circuits that instantly disconnect the speakers if a
potentially damaging signal is detected. Built
to Last We believe that when you
compare all these standard features to any other amplifier,
youll see why the ARX AmbiDrive should be your next
amplifier. As a company, ARX is
dedicated to producing pro audio products that consistently
deliver the power and the quality that audio professionals
expect. The AmbiDrive is proof of our commitment - an
amplifier that works as hard as you do at keeping your
clients coming back for more. AmbiDrive

All Channels driven
A
three channel amplifier (A + B + Sub) designed for our very
popular Ambience series of installation speakers, but also
eminently suitable for any similar Sub/Satellite speaker
system. A distillation of our experience gained through
years of making compact, powerful amplifiers.
Designed to be a straightforward, convenient way to supply
all amplifier functions within the one unit, the AmbiDrive
can easily handle any professional medium power
applications.
A
and B input connectors (XLR and jack, for added convenience)
on the rear panel feed into an onboard plug-in Sub crossover
card. This can be customised for non-ARX systems, but
normally sums the signal below 100Hz in both channels and
presents it at a separate Sub output connector. For a
satellite speaker/sub woofer system, the AmbiDrive is all
the amplifier youll ever need!
If you'd prefer to
use the Sub channel for something else - monitors, for
example - then simply plug into the Aux to Sub Channel
connector on the rear, and all the power of the Sub channel
is available to use as a full range output.
We've done everything we can to make the AmbiDrive the most
useful, flexible amplifier solution.
Dual variable speed
cooling fans circulate air through ARXs proprietary
UltraFin heatsink to stabilise the
AmbiDrive temperature. When the amp is idling, so are the
fans. When the internal temperature rises, so does the fan
speed to maintain an optimum temperature.

heatsink detail
The AmbiDrive weighs just 12 kilos (26 lbs) - light enough
for a single person to carry and install.
Using a high efficiency low mass toroidal transformer,
coupled with advanced computer modelling techniques has
enabled us to put the strength where its needed, and
to reduce unnecessary weight where possible.
Youll appreciate the fact that its a re-settable
circuit, too, not a simple one time only crowbar
system that has to be stripped down to be replaced.
