 PA Power Amplifier 4 x 160 W 4 Ohms

Multichannel Power with Minimum FootprintThe T Series multichannel power amplifiers have been designed especially for installation and networked audio systems. T Series amplifiers* are available with 4 and 8 discrete channels and output ratings from 160 to 320 Watts per channel providing optimum solutions for multizoning. They feature Euroblock inputs, terminal strip outputs and a rugged 2U rackmountable chassis with 4 mm front panel. *Also available as GPIO versions with remote and emergency paging switchin Main Features
  • 8 and 4-channel models with 300 and 150 Watts (RMS) output power per channel
  • compact 2U rackmountable chassis, 220 mm deep, weight 6 kg only
  • GPIO versions for remote and emergency paging switching
  • FCM system
  • oversized heat dissipation system for maximum thermal stability
  • low THD and high S/N ratio
  • all channels bridgeable in pairs
  • switchable input gain (26, 32 and 38 dB)
  • subsonic filters for each channel (35 Hz)
  • intelligent, quiet fan cooling system
  • terminal strip loudspeaker connectors
  • PCBs with surface-mount technology (SMT) for increased reliability
  • balanced inputs with superior noise rejection
  • select high-quality components only
  • ICL intelligent clip limiters for each channel
  • recessed volume controls (optional SC-T perspex guard)
  • high-efficiency two-stage Class H design
  • protection, signal, clip, power on and standby LED indicators for each channel
  • compact QuantaPulse power supply
  • multi-voltage: automatic voltage converter for worldwide use, no switching required
  • protections: soft start, turn on/turn off muting, thermal overload, DC, RF, short circuit, open circuit, load mismatch and power supply overload
ICL™: improved Intelligent Clip Limiting prevents loudspeaker damage while maintaining audio quality and punch under clipping conditions. FCM™: the Faulty Channel Management system prevents overall amplifier shutdown. GPIO:General-Purpose-I/O-Port QuantaPulse™ Technology: The Soft Switching Resonant QuantaPulse Power Supply is designed to provide plenty of power when needed monitoring the necessary parameters of voltage and current for a controlled performance at all times. Bi-directional data flow between the power supply and power amp module. Two very important characteristics of the QuantaPulse power supply are the optimization against over-voltages and superior reliability.
