Redback 250W Public Address (PA) Power Amplifier A4380A Made in Australia

Description

These booster amplifiers are suitable for high-powered installations where each zone requires a specific wattage. They are perfect for shopping centers, pedestrian areas, public transportation hubs, and convention centers. All models can run on both 240V AC and 24V DC for battery backup. The input is through a 3-pin balanced XLR (1V), with a rear-mounted level control to prevent tampering or accidental adjustment.

The Redback 250W Public Address (PA) Power Amplifier A4380A, made in Australia, boasts a circuit design with built-in protection features for output over voltage, over current, and over temperature conditions. These features are self-resetting once the fault condition is eliminated. Amplifier status is always displayed through front panel LEDs, providing visual indication. To ensure reliable operation at all times, the amplifier features on-demand fan cooling. Additionally, a dedicated nominal 24V dc 1A output is included on the rear to power additional devices. The unit is also equipped with rack ears for easy installation.
