For decades, DYNACORD has been one of the leading manufacturers in the pro audio sector and has established a com­manding position in the amplifier market thanks to the excellent audio performance, absolute reliability and high stability of
the Linear Precision series.

PHILOSOPHY

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.

CLASS - H TECHNOLOGY

Dynamic limiters are general components in all DYNACORD power amplifiers.
High-speed audio processors are continuously comparing the input signal to the
output signal, and in the event of any non-linearity, the processors send control
signals to the limiters, which operate dynamically upon the input level. As a result,
the THD all the way up to 21 dBU is limited to an inaudible 1% at the output.

DYNAMIC LIMITERS

The retrofittable NRS 90268 kit, which is available as an option for all CL power
amplifiers, combines the patented LPN (low-pass notch) filter with a low-cut filter.
These eliminate transient non-linearities in the low frequency range in small to
medium-sized full-range speakers and thereby considerably extend the reprodu­cible range at the bottom end. The acoustic result is bass reproduction with more
punch and greater substance.

LPN + LO-CUT

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 2x 400 watts and 2x 1000 watts
into 4 ohms. Even complex loads as low as 2 ohms
can be driven with absolute reliability. 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.
