The C 28:4 is one of two mid-power 4-channel amplifiers in the C Series family providing 4 x 700 W output into 4 ohms loads, packaged in 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 PC software, and remote control of channel mutes and power on/off is under network control.
