Our Story - Lab.gruppen C Series C 10 4X Installation Manual

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.

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.
