The C Series comprises eight models divided into
two application-specific platforms: four C Series
high-power models; and four C…X models offering
either four or eight channels plus features
specifically tailored to distributed systems.
Listen. It’s a Lab.gruppen.
The C Series is designed, first and foremost, to
deliver accurate and musical amplified sound - not
just raw power. Sonic transparency has been the
hallmark of Lab.gruppen amplifiers for more than
25 years. It continues as a goal that will not be
compromised at any stage of design, engineering
or manufacture.
Simply put: it’s the sound that matters.
Selectable Gain and VPL: optimize
for any signal, any load
All C Series amplifiers feature
adjustable input gain, allowing you
to optimize the balance between
headroom and noise floor. Gain is set
globally in four-channel models, and
in blocks of four channels on eight-
channel models.
At the other end of the amplifier
signal chain, the VPL (Voltage Peak
Limiter) lets you individually tailor
each output for the characteristics
of the connected load. For direct
drive of high-impedance systems
(no transformers required), simply
select the appropriate VPL setting.
Other VPL settings are appropriate
for different driver combinations in
bi- and tri-amplified systems, and for
large subwoofers. VPL is switchable
for Hard or Soft attack characteristics:
Hard is preferred for low-impedance
and subwoofer applications, Soft
for most high-impedance loads.
Pick your bridges
All channels on C Series amplifiers
are bridgeable, and adjacent pairs can
be bridged independently. This puts
bridge-mode operation in a whole
new context. For example, using the
C 20:8X in a restaurant system, you
could bridge two channel pairs for
ceiling subwoofers and still have four
channels left for driving four separate
mid-high zones, either low-impedance
or 70 / 100 V.
Bridging amplifier channels normally
introduces 6 dB of gain, but C Series
amplifiers compensate with an
automatic reduction (-6 dB). Gain is
constant on all channels, making it
easier to specify and align loudspeakers
connected to a mixture of bridged and
non-bridged channels.
Comprehensive protection for
non-stop service
All Lab.gruppen amplifiers incorporate
the industry’s most extensive suite
of protection features. Even when
stressed by extreme conditions
or random mishaps, the C Series
protection circuits make it virtually
impossible to damage the amplifier
circuitry or connected loudspeakers.
Standard protection features include:
•
CPL (Current Peak Limiter)
Keeps output devices operating within
current handling capability.
•
Temperature protection
Keeps amplifier within thermal limits.
•
VHF (Very High Frequency)
Monitoring safeguards drivers from
damage by continuous, non-musical
VHF signals.
•
DC protection
Prevents any direct current at outputs
.
•
PAL™ (Power Average Limiter)
Monitors current draw to prevent
power interruption
•
Low-impedance warning
Guards against failures from
short-circuits.
•
High-impedance warning
Indicates blown or disconnected drivers.
•
Soft-start (low inrush)
Prevents mains breaker tripping at
power-up.
