The Lectrosonics DM1612f is a powerful digital audio processing, mixing and routing system. The primary applications are sound reinforcement and conferencing in boardrooms, courtrooms, worship centers, distance learning systems, hotels and other applications with multiple microphones and loudspeakers. The design represents a milestone in DSP technology in its basic architecture and in its processing speed and efficiency.
The basic architecture consists of 16 mic/line inputs and 12 outputs with a full DSP-based crosspoint matrix that allows every input to be routed to any or all outputs. Following the A-D conversion at each input, the signal passes through multiple DSP filters, ADFE (automatic digital feedback eliminator), a compressor and a digital delay. In the matrix, gain is adjustable from -69 to +20 dB in 1 dB steps at each crosspoint. Each of the 12 outputs provides a digital delay, multiple DSP filters and a compressor/limiter.
The rear panel of DM Series Matrix Mixers provide all connections for microphones, line inputs, line outputs, external computer control, and EXPANSION ports for "daisy chaining" multiple units or connecting other LecNet2 devices. Logic I/O ports are also provided for remote control and signaling with external pots, switches and LEDs.Industry standard depluggable connectors are used for audio inputs and outputs, DB25 connectors provide taps for logic control. USB and serial jacks are provided for the computer interface. A quad RJ45 connector block provides expansion ports for "daisy chaining" multiple
units, or interfacing with another LecNet2 device.
