Description

Our range of Class D power amplifiers are proven and robust. Three power amplifiers are available in the range: BV225 (225 Watt), BV125D (2 x 125 Watt) and the BV050Q (4 x 50 Watt).

Key Features

  • Designed for quick and simple connection and configuration.
  • Class D rated output power is attainable using a 22V battery supply.
  • Sleep mode – automatically reducing the standby requirements to 50mA per amplifier when operating on batteries.
  • Audio inputs are presented on separate RJ45 connectors; each connector provides a balanced audio input and ground.
  • Protected against overload conditions (ie short circuits) by means of a voltage controlled attenuator (VCA); ensuring continual safe operation without creating unnecessary distortion.
  • Over temperature protection is also provided. Should the amplifier temperature exceed 90?C the VCA attenuates the input signal to a safe level and illuminates a warning LED. If the system is under surveillance a fault condition will be indicated due to the gain reduction.
  • 24V DC inputs are presented on two-way crimp connected sockets.

BV225:

  • 225W class D power amplifier with a single 500mV balanced line audio input and 100V line output.
  • Can either be used as an independent amplifier module, can be one of two amplifiers wired as an A/B dual circuit using a single input signal or can be paralleled with other BV225 units to enable higher power outputs.
  • BV225 units are easily paralleled via RJ45 connectors.

BVMF MAINFRAME:

  • Three amplifier modules (or two amplifiers and one BVSMP power supply) may be mounted in one BVMF
    mainframe.
