The C 68:4 delivers an amazing 4 x 1700 W at 4 ohms making this amplifier powerful enough for the most demanding of installed sound applications. Packaged in only 2U this is extreme power-density - arguably the highest and most impressive for 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 PC software, and remote control of channel mutes and power on/off is under network control.
