This range of booster amplifiers are ideal for installations requiring high power zone amplifiers. Simply choose a power rating according to the wattage required for each zone. These high power models are ideal for use in shopping centres, pedestrian precincts, public transport facilities and convention centres. All models operate on 240V AC and 24V DC for battery backup operation. Input is via 3 pin balanced XLR (1V). Level control is rear mounted to prevent tampering or accidental adjustment.

The circuit design includes protection features in case of output over voltage, over current and over temperature conditions. All are self resetting once the fault condition has been removed. Visual indication via front panel LEDs show amplifier status at all times. On demand fan cooling ensures reliable operation at all times. A dedicated nominal 24V dc 1A output is provided on the rear to power ancillary devices. This amplifier is supplied with rack ears.
