The C 16:4 is one of two mid-power, four-channel amplifiers in the C Series family. Attractively packaged in a 2U chassis, it provides 4 × 400 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.

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.

Note 1): Automatic -6 dB gain compensation when bridging channels. Ch.’s A+B and/or C+D, can be bridged individually.
Note 2): PAL can reduce the maximum output power to keep the power supply operating safely, and/or to prevent excessive current draw tripping the mains breaker.
Refer to Operation Manual.
Note 3): For sine waves, peak voltage output values translate to Vrms with the formula V/1.41 = Vrms. E.g. 100 V peak equals app. 70 Vrms.
Hence, outputs can be set for high-impedance loads without requiring a transformer.
