LabGruppen C48:4 – Amplifier

LabGruppen C48:4 – 4800W 4-Channel Amplifier with NomadLink Network Monitoring and Dedicated Control for Install Applications

The C 48:4 is the third largest amplifier in the C Series family, delivering an impressive 4 × 1200 W at 4 ohms. The exceptional power output plus a long list of protection and monitoring features are all packed into a 2U chassis.

C Series amplifiers are uniquely capable of adapting to a wide variety of demanding load conditions. Each channel has an individually configurable Voltage Peak Limiter (VPL™), which allows the output to be optimized for any loudspeaker load – whether a single large subwoofer or a series of small 100/70 V loudspeakers. VPL works in combination with adjustable input gain to achieve maximum headroom regardless of input levels or output impedances.

Every C Series is ready for the NomadLink® network right out of the box. With NomadLink, key amplifier parameters are displayed via DeviceControl software, and remote control of channel mutes and power on/off is under network control.
