Our MD12 is a 2U high rack-mount audio distribution amplifier specifically designed to distribute a professional quality mono audio signal to the Media.

the associated XLR for maximum versatility. The outputs can be used in any combination of balanced, unbalanced, grounded, ungrounded, line level and microphone level. The settings and connections of any output will not affect the others. Input levels from +24dBu down to -16dBu may be adjusted for +4dBu line level output. The rack mounting hardware can be removed or reversed and the mains connector can be on the input (default) or output panel.

The input panel has a high impedance balanced line level input with male and female XLR's for looping through, ±20dB screwdriver accessible gain adjustment, l.e.d. level meter and ground lift switch. On the output panel there are twelve audio outputs and a level meter. All outputs are electrically isolated and each output has it's own line / mic. level switch (0dB / - 40dB) plus a ground lift switch. Six outputs have a 6.35mm stereo jack socket and the other six have an RCA/Phono socket in parallel with
