Digital Automatic Matrix Mixer

The DM1612F from Lectrosonics is a digital audio processor, that shares many of the DSP functions common in the marketplace, but with a very comprehensive routing system that allows any input to be patched to any single or multiple outputs simultaneously. Primary applications include sound reinforcement, boardroom conferencing, houses of worship, courtrooms and hotels. Any place which requires the use of multiple microphones and loudspeakers.

The unit provides 16 microphone/line inputs, 12 line outputs (4 switchable to microphone output) with each input possessing a fixed sequence of multiple DSP filters, ADFE (automatic digital feedback eliminator), a compressor and a digital delay. During the routing stage (the matrix mixer), gain can be adjusted and then each output provides a digital delay, multiple DSP filters and a compressor/limiter. Modules have extensive editing parameters, and can be switched in or out of the signal path as required.

DM1612F features include:

• 16 mic/line inputs, 12 line outputs
  (4 outputs are mic/line switchable)
• 16 x 12 digital matrix mixing; gain is adjustable from
  -69 to +20 dB
• Proportional gain auto mixing algorithm with AutoSkew™
  - US Patent 5,414,776 and 5,402,500
• Auto mixing operates at the output of the matrix - each input channel can participate differently in each output mix
• Each output has its own NOM mixing bus
• 6 filter stages plus compressor, ADFE and delay on each input
• 9 filter stages plus compressor, limiter and delay on each output
• 128 macros available for storing up to 64 commands per macro
• USB and RS-232 interfaces for setup and control
• Digital I/O ports for "daisy chaining" and to connect other LecNet 2 devices
• AMX© and CRESTRON™ compatible
• Simultaneous LecNet2 and Third-Party control
• Continuous fan cooling
