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.

Features

  • 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
