An Installation Amplifier without Compromise
Lab.gruppen ampliers have earned an enviable worldwide
reputation for sonic excellence and rock-solid durability in touring
sound applications. These same qualities are now available for a
broad range of installed sound applications in the C 10:8X amplier.
By offering an unmatched combination of channel density, operating
efciency and conguration exibility, the C 10:8X presents convin-
cing performance and cost-saving advantages. Applications include
primary systems for theme parks, shopping malls, airports, hotels
and restaurants as well as auxiliary systems for performance
venues, houses of worship and numerous other installed sound
applications.
To achieve higher channel density without compromising per-
formance, Lab.gruppen engineers developed a new output stage
design. Based on a patented Class D circuit topology, these output
stages produce sustained high power levels with very low distortion
while maintaining efciency levels of near 90%. A new universal
switching power supply employs Power Factor Correction (PFC) to
stabilize current draw, and it accepts any mains voltage from 65 –
265 V (+/- 10%) @ 50 Hz or 60 Hz through the appropriate IEC cord.
The C 10:8X includes include unique features which enable each
unit – or even each channel – to be congured for a specic
application or load condition. Input gain is selectable in four-channel
groups, and a 35 Hz high pass lter may be inserted. All channels
are bridgeable in pairs, and Lab.gruppen’s exclusive Voltage
Peak Limiter (VPL) feature allows each channel to be individually
optimized for the reactive characteristics of the connected load.
For comprehensive remote monitoring and control, the C 10:8X
includes NomadLink network ports for connecting to an optional
NLB 60E NomadLink Bridge & Controller Network and an Ethernet-
linked PC. With NomadLink, key amplier parameters are displayed
via DeviceControl software, and remote control of channel mute
and power on/off is under network control. Alternatively, the GPIO
facilities allow access to key amplier functions via third-party
remote control systems.
To ensure a long and trouble-free service life, the C 10:8X
incorporates extensive features to safeguard internal circuits and
connected loads. Protection and warning circuits prevent damage
or service interruptions due to excessive current, DC at output,
over-temperature, non-musical VHF (very high frequencies), and
open load conditions. In addition, soft-start and PSU current limiting
protect the mains supply from interruptions due to tripped circuit
breakers or blown mains fuses.
