Päätevahvistin PSSO DDA-3500 3500W Class D

PSSO DDA-3500 is a Class D power amplifier delivering a rated output of 3500W for professional audio systems. Designed for high-power applications, the amplifier supports loudspeakers in large venues, touring rigs and fixed installations. The Class D topology emphasises energy efficiency and lower heat generation compared with traditional linear designs, enabling sustained high-output operation while minimising cooling requirements.

Advantages

The amplifier offers high continuous power suitable for driving large PA loudspeakers and subwoofers, with Class D efficiency that reduces power consumption and thermal load. The compact form factor and robust build make it suitable for rack mounting and transport in touring environments. Onboard protection ensures stable operation under demanding conditions, and low idle heat improves reliability during extended use.

Key specifications

How to use

Install the amplifier in a standard equipment rack or on a stable surface with adequate ventilation around the chassis. Connect the unit to a compatible power source that meets the amplifier's voltage and current requirements and use appropriate speaker cabling and connectors rated for high-power PA use. Route input signals from the mixer or signal processor to the amplifier inputs, set input gain and crossover settings according to the loudspeaker manufacturer's recommendations, and gradually increase output level while monitoring sound and amplifier indicators. Observe the amplifier's protection LEDs and avoid sustained clipping or overload conditions.
