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 in boardrooms, courtrooms,
worship centers, distance learning systems, hotels and other applications with
multiple microphones and loudspeakers. The design is ideally suited to mix-minus
sound reinforcement systems.
Lectrosonics DMPA12 Features:
- 12-channel class-D power amp with bridge tied load (BTL)
- 10 Watts per channel; adjacent channels can be tied together for doubled
- Every output channel includes a DSP delay, nine filters, compressor and
- 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
Inputs are taken from the DANI™ 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.
Class-D amplification is implemented with a late generation component that
provides exceptional efficiency, low heat, excellent audio performance and is
indestructible with wiring errors. Each output channel includes a delay, nine
filters, a compressor and limiter. Settings are stored in memory with different
24 presets available for immediate recall of all setup parameters. Presets can
be recalled with serial commands or simple contact closures.
