DISC Lab Gruppen C16:4 Amplifier

Full Description

Like all the models is the C series, the C16:4 is capable of adapting to a wide variety of load demands, as well as having individual configurable Voltage Peak Limiter (VPL). This enables the C16:4 output to be optimised for any loudspeaker load as well as working with adjustable input gain to achieve maximum 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 offer superb sound quality.
