Description

The C 48:4 is the third largest amplifier in the C Series family, delivering an impressive 4 × 1200W at 4 ohms. The exceptional power output plus a long list of protection and monitoring features are all packed into 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 100/70V 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.

Features

  • Unprecedented power density – Total output of 4800W (4 ohms) in a 2U cabinet
  • Four channels – All channels bridgeable for 2- or 3-channel configurations
  • Lo-Z or Hi-Z (70V / 100V) – 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
