Description
The DPA is a Class-D digital power amplifier featuring extremely low power consumption (0.2 W per channel) during standby mode and high amplification efficiency of 90%. A four-step DIP switch allows configuration to enable or disable standby mode (power-save mode) when powered by AC mains, control front panel LEDs to comply with EN 54-1, enable or disable battery monitoring.
The amplifiers are powered by 100–240 VAC (50/60 Hz) or a 48 VDC battery backup. Each model includes line inputs with individual volume gain controls and front panel status LEDs for power, battery, fault, general fault, overload, and signal. DPA models also support channel bridging to double the output wattage.
