of audio performance. One of
the key advantages of Grounded
Bridge solutions is the considerable
reduction in ‚voltage stress‘ for the
power transistors. This permits
the design of high-powered power
amplifiers with peak output voltages
in excess even of 200 V.
A logical step in the direction of
lowering power dissipation whilst
at the same time increasing the
output power was the development
of a linear Grounded Bridge topo-
logy using Class H technology with
a multi-stage switching ‚floating‘ po-
wer supply. The use of an extremely
stable switching power supply
makes a decisive contribution to
the very low weight of these power
amplifiers: 7 kW packed into a device
a mere 2 rack units in height and
weighing less than 15 kg!
PowerH power amplifiers are ready
for integration into IRIS-Net-based
audio systems and networks.
Remote control modules (e.g. the
RCM-26) that can be retrofitted
offer complete system supervision
and remote control combined with
digital controller functions.
