Lab.gruppen C Series C 10 4X Installation Manual - E C
Patented Class D output for high
efficiency
C…X amplifiers employ a new,
patented and highly refined Class D
implementation that is ideally suited
to lower power levels where the
advantages of Class TD are marginally
beneficial. This output stage produces
sustained power levels with very low
distortion while maintaining efficiency
levels close to 90%.
Universal PSU: works anywhere in
the world
The new universal switching power
supply employs PFC (Power Factor
Correction) to stabilize current draw,
and it accepts any mains voltage from
100-230 VAC (+/- 10%) @ 50 or 60 Hz
through the appropriate IEC cord. The
overall result is a flat frequency response
into reactive loads, emulating the output
characteristics of the high-power
C Series amplifiers to maintain a uniform
sonic signature throughout the line.
Built-in GPIO
for control
compatibility
For quick
interfacing with
third-party control
systems, C…X
amplifiers provide GPIO capability via
two rear-panel Phoenix connectors.
The OUT connectors create a closed
connection when the amplifier is turned
on (OUT 1) or when a fault condition
exists (OUT 2). The IN connections can
be set via DIP-switch for two toggled
power on/off connections, or for a
single “same state” (closed = on /
open = off) response.
High-pass filter tailors response for
each channel
Each channel of the C…X amplifier
offers an individually selectable high-
pass filter. The 35 Hz rolloff frequency
allows full-range operation while
cutting subsonic frequencies that are
problematic in many high-impedance
applications.

The C Series C...X models are matched to a wide range of channel-hungry
applications, including multi-zone installations typical of restaurants and retail
outlets, transportation facilities, schools, museums, and boardrooms. These
applications benefit from availability of higher channel density, built-in GPIO
functions, a switchable high-pass filter, and a universal power supply.
A new
amplifier
standard,
three
decades in
the making
Years before
the company
was
established in 1979, co-founders
Kenneth Andersson and Dan Bavholm
already had earned a reputation as
bold innovators with a passion for
building better audio equipment.
One of their first hand-built products,
a custom mixer, was pressed into
service for a performance by legendary
singer Eartha Kitt when she visited
their hometown of Kungsbacka,
Sweden. At the time, the two
basement builders were full-time
schoolboys still in their mid-teens.
Soon after launching Lab.gruppen,
the duo expanded their product line
to include AXE-AMP guitar amplifiers.
When an OEM output stage used
in the earliest models proved
foundational advances, Lab.gruppen
steadily built a loyal following
among leading sound rental
companies. At first distribution was
limited to the Swedish market, then
gradually expanded into the rest of
Europe. Demand often threatened
to outstrip supply, but quality
control standards never were
compromised in order to ship more
product. Only after a larger, highly
efficient manufacturing plant (still
in Kungsbacka) came on line was
product distribution fully expanded
into North America and Asia.
A commitment to the sound
installation industry
With the introduction of the
C Series, Lab.gruppen has set new,
higher standards for sound quality,
reliability and ease of integration
into systems for any installed sound
application. Whether the project at
hand is an elite restaurant, a
performing arts center, or a
massive stadium, Lab.gruppen
C Series amplifiers are first choice
for performance, installation
efficiency and overall end-user
satisfaction.
unsatisfactory, Kenneth Andersson
set out to design and build circuits
that sounded better and could not be
“smoked”. The result was used in all
subsequent guitar amplifiers and, in
late 1980, incorporated into the SS 300
- Lab.gruppen’s first power amplifier.
Building on breakthroughs
Over the following two decades,
Lab.gruppen achieved a remarkable
number of breakthroughs in power
amplifier design. The copper-finned
Intercooler
®
removed heat from
amplifiers with unprecedented
efficiency. The Regulated Switch
Mode Power Supply (R.SMPS) proved
that a truly lightweight amplifier
could indeed be reliable, sonically
transparent, and free of excessive
ambient noise. The innovative MLS
(now VPL) circuit allowed amplifier
outputs to be tailored to load
characteristics. And the patented
Class TD output stage combined the
low distortion of Class B with the high
efficiency of Class D designs.
Building on these and other
Over the past decade, Lab.gruppen amplifiers
have rapidly emerged as the benchmark for quality
and durability in power amplification. Yet the term
“overnight success” hardly applies here. The roots
of Lab.gruppen technology extend back more than
three decades.

All C Series amplifiers are shipped
NomadLink-ready as standard. Though
powerful and comprehensive,
NomadLink
®
is remarkably simple to
set up and use. Within minutes you
can network a rack full of amplifiers
simply by clicking in standard Cat-5
cables to form a fully redundant
daisy-chain loop. As many as 60
high-power C Series amplifiers (or up
to 30 C...X amplifiers) can be included

in a single subnet, and up to 16
subnets can be monitored and
controlled from a Windows PC
running Lab.gruppen’s proprietary
DeviceControl software. With
NomadLink

, one laptop can supervise
a system with up to 3840 amplifier
channels.
NLB 60E - NomadLink
®
Bridge &
Network Controller
The keystone component in each
NomadLink
®
subnet is the optional
NLB 60E NomadLink
®
Bridge &
Network Controller. It primarily
functions as a bridge between
connected NomadLink
®
subnets and
the DeviceControl software on the
host PC. Connection between the PC
and NLB 60E is via standard TCP/IP,
either directly (peer-to-peer) or over a
wired or wireless LAN. The NLB 60E
provides power on/off and mute
functions directly from the front-panel,
and programmable GPI functions for
interfacing with third-party control
systems. The NLB 60E also maintains
phantom power to the NomadLink
®
modules in the amplifiers, allowing
them to remain online even when
mains power is off. NomadLink
®
provides automatic detection of
devices in physical order in the
network, and facilitates automatic
uploading of all amplifier data into the
DeviceControl software. Users can
modify uploaded configurations, or
create new system configurations
offline for later matching to physical
amplifier systems. In addition to power
sequencing, power on/off, Mute and
Solo functions, DeviceControl provides
comprehensive monitoring of amplifier
status and clear warning of potential or
actual fault conditions.
