Lectrosonics DM812 DIGITAL MATRIX AUDIO PROCESSOR, 8 IN, 12 OUT
The Lectrosonics DM812 is a professionally designed powerful digital audio processing, mixing and routing system. The primary applications are made sound reinforcement and boardrooms, conferencing in worship centers, courtrooms, distance learning systems, hotels and other applications that comes along with multiple microphones and loudspeakers. The design comes representing a milestone in DSP technology in its basic architecture and in its efficiency and processing speed.
The basic architecture comes consisting of 8 mic/line inputs and 12 outputs that comes along with a full DSP-based crosspoint matrix that is allowing every input to be routed to any or all outputs. Following the A-D conversion at each input, the signal is passing 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 24 outputs comes providing a digital delay, multiple DSP filters and a compressor/limiter.
