DISC Lab Gruppen C10:4X Amplifier

Full Description

The C10:4X delivers 4 x 250W at 4 ohms, 8 ohms and 16 ohms or 70 Vrm; 500W at 100Vrms available in bridge mode. Like the other 4 CX models within the C series, the C10:4X is specifically designed to suit installation applications with lower power output requirements. Like the other higher power C series models, the CX have the same lightweight 2U chassis, however, they are available in 4 and 8 channel versions for greater channel density and improved flexibility for installations. The amplifier can adapt to a variety of difference load conditions and each channel has its own configurable Voltage Peak Limiter (VPL) to optimise the output of the loudspeaker load. The VPL works alongside the adjustable input gain to maximise headroom.

Lab Gruppen C Series

The Lab Gruppen C series of 4 and 8 channel amplifiers provides the solid foundation of install- dedicated amplifiers, with innovative features that make them perfect for the modern installation AV market. The C series is incredibly versatile, reliable and offers superb sound quality.
