VIGIL2 AMPLIFIERS

The BV050Q

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).

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 requirement of

BS5839-8:2008) a fault condition will be indicated due to the gain reduction.

• 24V DC inputs are presented on two-way crimp connected sockets.

BV050Q:

• Contains four independent 50W class D power amplifiers, each with a single balanced line audio input and 50W

100V line output.

• Can either be used as four independent amplifier modules or four amplifiers wired as an A/B dual circuit using a single input signal.

• Channel gain may be individually set using the potentiometers on the board behind the front panel.

BVMF MAINFRAME:

• Three amplifier modules (or two amplifiers and one

BVSMP power supply) may be mounted in one BVMF mainframe.
