The PA Series are a range of high-power amplifiers built to have outstanding sound quality , excellent power efficiency , & guaranteed operational reliability .The series is now hybrid; which means it can run stable even on lower supply voltages. It uses both power supplies; Switch Mode power supply to work on voltages & at the same time Linear Power Supply to give a as Low as 130V punch packed performance.

  • Professional high-power amplifiers.
  • Input: Balanced XLR and 1/4” Stereo Jack.
  • 3 switchable operational modes: Stereo, Mono & Bridge.
  • High-current toroidal transformers with high-grade cores for greater transient response & low-noise even at 2 Ohms.
  • High quality glass epoxy, double-sided PTH PCB’s & high-grade components ensures reliability in even tough ambient environs.
  • Intelligent cooling using low-noise variable speed fans & direct mounted over-designed heat-sinks.
  • Sensitivity (0dB or+4 dB) selection switch allows flexibility in connection of input sources.
  • Switchable Low-cut switch for protection & tight-low end performance.
  • Switchable Limiter Switch to protects speakers from damage due to distorted input signals.
  • 41-detent rotary volume knobs.
  • Mute, Signal, Clip and fault LED indicators assists you to monitor performance.
