cl 800
Rated at 2 x 600 watts into 2 ohms and 2 x 400 watts
into 4 ohms, the smallest power amplifier in the CL
series, which uses class AB technology, weighs in at
a mere 13 kg and is therefore the ideal amp for fairly
small full-range cabinets.
cl 1200
Delivering a reliable 2 x 900 watts into 2 ohms and
2 x 600 watts into 4 ohms, this is the ideal amplifier
for a wide variety of full-range cabinets and MF/HF
components in multi-way systems.
cl 1600
Rated at 2 x 1100 watts into 2 ohms and 2 x 800
watts into 4 ohms, this amplifier is ideal for use with
professional full-range cabinets and also passive
TOP/SUB combinations.
cl 2000
The flagship of the CL series delivers a beefy 2 x 1400
watts into 2 ohms and 2 x 1000 watts into 4 ohms,
whilst weighing a mere 18 kg. Ideal for driving large
subwoofer arrays as well as full-range and MID-HIGH
components with high power handling.
lpn + lo-cut
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-linearity in the low
frequency range in small to medium-sized full-range
speakers and thereby considerably extend the repro-
ducible range at the bottom end. The acoustic result
is bass reproduction with more punch and greater
substance.
dYnaMic liMiters
Dynamic limiters are general components in all DYNACORD
power amplifiers. High-speed audio processors are
continuously comparing the input signal to the out-
put 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 limi-
ted to an inaudible 1% at the output.
