Tascam MM-4D 4-Channel Mic/Line Input Dante Converter

The MM-4D/IN series from TASCAM is a 4-Channel Mic / Line Input Dante Converter with built-in DSP Mixer that is designed to respond to various needs of the contractor market and professional audio scene. This compact converter comes in two versions - the MM-4D/IN-E which offers Euroblock connections on the rear; while the MM-4D/IN-E is constructed with XLR connections on the back.

These converters are about half the size of a standard 1U rack, with the MM-4D/IN-X being suitable for different Dante systems as an exquisite analog output unit. The built-in DSP mixer enables small scale systems to fully perform with a variety of input/output models the TASCAM Dante Compact Processor Series offers. MM-4D/IN-X supports up to 96kHz/24bit and uses XLR connectors for analog mic/line input along with offering phantom power capability. The MM-4D/IN-E also supports up to 96kHz/24bit with phantom power available and uses Euroblock connectors for analog mic/line input.

The Dante Compact Processor Series provides easy additional mic/line or AES/EBU input/output to several situations and places such as public facilities, broadcasting stations, recording studios, etc. where Dante systems are being used. They are the optimal input/output unit for small scale environments. These processors are equipped with a matrix mixer that includes a DSP feature with compressors, parametric EQs, limiter, delay, etc. functions. From the input of microphone signals to the output of powered speakers; also applicable with recording/playback systems, the Dante Compact Processor Series can build up a complete small system on their own.
