The Lectrosonics DM84 Digital Matrix Processor can route any combination of inputs to any combination of outputs with extremely low throughput latency. Automatic microphone mixing is accomplished via a patented Adaptive Proportional Gain algorithm. Sophisticated filtering is offered on each input and output. A compressor is available on each input, a compressor and limiter on each output. In addition, each input and output can be configured with a delay setting of up to 100 ms for inputs, 250 ms for outputs. The DM84 runs on the latest-generation DSP architecture and can be integrated as part of a larger system by connecting other DM units (like the DMTH4) via the Digital Audio Network Interface (DANI) bus.
