225W Class D Power Amplifier with a Single 500mV Balanced Line Audio Input and 100V Line Output.

Description

• 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.
