Digital Power Amplifier

The Lectrosonics DMPA12 is a powerful digital audio processor and multi-channel power amplifier combined into a single rack space component designed to work with DM Series processors. The design represents a milestone in DSP technology in its basic architecture and in its processing speed and efficiency. The primary applications are sound reinforcement and teleconferencing systems in boardrooms, courtrooms, lecture halls, distance learning applications, hotels and other systems with multiple microphones and loudspeakers. The design is ideally suited to mix-minus sound reinforcement designs. Inputs are taken from the DANITM bus (Digital Audio Network Interface) which is common to all DM Series components. Each output can drive a variety of loads, including loudspeakers, long cable runs and headphones. The BTL configuration allows two adjacent channels to be wired in parallel on a common load to double the output power. The amplifier is designed to run continuously (idle or with a load) without heat buildup, making it ideal for permanent installations where prolonged operation is required.

DMPA12 features include:

  • 12-channel class-D power amp with bridge tied load (BTL)
  • 10 Watts per channel; adjacent channels can be tied together for doubled output power
  • Every output channel includes a DSP delay, nine filters, compressor and limiter
  • Passively cooled; no heat buildup
  • Inputs are taken from the Lecnet 2 DANI™ bus forward or backward propagated final mix signals - no analog inputs are provided
  • Front panel level controls and LED signal status indicators
