The C 28:4 is one of two mid-power, four-channel amplifiers in the C Series family. Attractively packaged in a 2U chassis, it provides 4 × 700 W output into 4 ohm loads.

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.

Unprecedented power density – Total output of 2800 W (4 ohms) in a 2U cabinet
Four channels – All channels bridgeable for 2- or 3-channel configurations
Lo-Z or Hi-Z (70 V / 100 V) – Selectable per channel, normal or bridged
Patented Class TD amplifier topology
Voltage Peak Limiter (VPL) – Configurable per channel to optimize each output for connected loads
Phoenix-type input connectors
Screw terminal output connectors
Comprehensive protection and warning – Excessive output current, DC, high temperature, very high frequency (VHF), short circuit, open load, mains fuse protection, and soft start
Efficient and uniform Intercooler® cooling
NomadLink® network ready


Power amplifier and proper packing for safe shipping if it needs to be shipped
