▸ Unprecedented power density – Total output of 1600 W
(4 ohms) in a 2U cabinet
▸ Four channels – All channels bridgeable for 2- or 3-channel
configurations
▸ Lo-Z or Hi-Z (70 V / 100 V) – Selectable per channel, normal or
bridged
▸ Patented Class TD amplifier topology
▸ Voltage Peak Limiter (VPL ) – Configurable per channel to
optimize each output for connected loads
An Installation Amplifier without Compromise
Installed or on tour, uncompromising quality begins with supe-
rior sound. Over the past decade, the sound of Lab.gruppen ampli-
fiers has earned praise from renowned FOH engineers and owners
of the world's premier sound rental companies. At the core of
the C Series high-power* model's tight and transparent sound is
patented Class TD technology. As a proprietary implementation of
tracking Class D, Class TD approaches the exceptional efficiency of
Class D while retaining the superior sonic quality of the best Class B
output stages.
A Regulated Switch Mode Power Supply (R.SMPS) contributes to the
remarkable efficiency of the C Series high-power models, while at
the same time providing stable operation even with wide fluctuations
in mains voltage. R.SMPS also works in conjunction with Class TD to
give extraordinary power density. More channels with more power
are condensed into a smaller package, allowing C Series amplifiers
to minimize rack space requirements and reduce installation costs.
Extreme power density demands efficient cooling, and here
Lab.gruppen's Intercooler proves remarkably effective. Thousands

of small copper cooling fins dissipate heat, and all output devices are
mounted on one row perpendicular to airflow for uniform cooling.
C Series amplifiers are uniquely capable of adapting to a wide
variety of demanding load conditions. Each channel has an
individually configurable Voltage Peak Limiter (VPL), which allows
the output to be optimized for any loudspeaker load – whether one

massive subwoofer or a series of small 100 V loudspeakers. VPL
works in combination with adjustable input gain to achieve maximum
headroom regardless of input levels or output impedances.
To assure reliability, and minimize service interruptions, C Series
amplifiers offer comprehensive warning and protection features.
Whenever faulty wiring, improper use, or extreme ambient tempera-
tures threaten trouble, a C Series amplifier gives clear and accurate
warning indications. Protection measures are inserted only when
dangerous thresholds are passed. Conditions are re-checked at
six-second intervals, and normal operation resumes when measure-
ments return to nominal.
Every C Series amplifier is ready for the NomadLink
out of the box. With NomadLink
displayed via DeviceControl software, and remote control of chan-
nel mutes and power on/off is under network control. (NomadLink
requires the separate NLB 60E NomadLink
troller.)
