Through the use of optimized power supplies with toroidal transformers
(on account of their low stray fields) and the intelligent application of
class H technology (CL 800: class AB), headroom way above the declared
nominal power has been achieved as well as a notable reduction in
weight and waste heat. CL power amplifiers satisfy the extreme demands
of life on the road and deliver between a nominal 2 x 400 watts and 2 x
1000 watts into 4 ohms. Even complex loads as low as 2 ohms can be
driven very saafely. Ranging in weight from only 13 kg to 18 kg, two or
more CL power amplifiers can be combined in racks that remain easy to
transport.
class-h technologY
With this technology, two different power supply rails are permanently available
internally to the power amplifier blocks. For most of the program material, the
lower operating voltage is able to reproduce the audio signal flawlessly;
however, as soon as there are dynamic peaks, the amplifier switches
internally and at high speed to the higher supply voltage.
Since for long periods the power amplifier blocks are operating with
the lower supply voltage, there is considerably less power dissipation than
with conventional class AB power amplifiers, which also means considerably
less waste heat.
