6800W 4-Channel Amplifier with NomadLink Network Monitoring and Dedicated Control for Install Applications

C SERIES C 68:4

The C 68:4 Delivers 4 × 1700 W at 4 OHMS, Making This Amplifier Powerful Enough for the Vast Majority of Demanding Installed Sound Applications.

The C 68:4 delivers 4 × 1700 W at 4 ohms, making this amplifier powerful enough for the vast majority of demanding installed sound applications. Packaged in a compact 2U chassis, the C 68:4 sets a new standard for high power in an installation-dedicated amplifier.

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 one massive 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 managed efficiently under network control.
