Lectrosonics

The DM1624 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, 24 line outputs (8 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. The DM1624 features an algorithm to help with the performance of multiple microphone sources. Each microphone input can be assigned to a different mode that will govern how that microphone behaves in respect to other open sources. Attenuation of various sources is done in an intelligent and seamless manner, eliminating gating and its detrimental effects. Further, since the processing happens on the output, each input can function differently at each destination. The unit can be programmed from the front-panel or via Windows software and a RS232 or USB equipped computer. Remote hardware control is also possible once the initial set-up is complete. Multiple units can be interfaced for greater system resources. Finally, all functions are available on all inputs and outputs without impacting DSP resources. Latency is minimal, even in multiple unit situations.None Digital matrix processor with 16 microphone/line inputs, 24 line outputs (8 switchable to microphone output)None 16 x 24 with gain adjustable from -69dB to +20dBNone Microphone outputs can be used for connecting to a recording device None Proportional gain auto mixing algorithm with "AutoSkew," a process that eliminates artifacts such as comb filtering and abrupt gating that occur with conventional automatic mixing schemesNone Auto mixing operates at the output of the matrix, with each input channel being able to participate differently in each output mixNone Each output has its own NOM (Number of Open Microphones) mixing busNone 6 filter stages plus compressor, ADFE (Automatic Digital Feedback Elimination) and delay on each inputNone 9 filter stages plus compressor, limiter and delay on each outputNone 128 macros available for storing up to 64 commands per macroNone USB and RS-232 interfaces for setup and controlNone Digital I/O ports for "daisy chaining" and to connect other LecNet 2 devicesNone AMX and CRESTRON compatible
