The TASCAM MM-4D/IN is a compact professional converter that converts four balanced analogue microphone or line-level inputs into Dante network audio.

It also receives four Dante input channels and includes an 8-input/4-output DSP matrix mixer, allowing the four analogue inputs and four Dante sources to be mixed, processed and routed to four Dante output channels.

Available Versions

MM-4D/IN-E

• Four balanced Euroblock microphone/line inputs
• External switch and LED-control connections
• Designed primarily for permanent installations

MM-4D/IN-X

• Four balanced female XLR microphone/line inputs
