Passive Direct Input Box

Our 2-channel Passive Direct Input Box.
The Direct Box MDI-2 is available in two versions: active (MDI-2A powered by 9V battery or Phantom power) and passive (MDI-2P).

D.I. boxes are essential to optimise the signal management of high impedance instruments such as keyboards, guitars and electric basses. A crucial partner in the studio and on stage, each MDI-2 provides for signal balancing and impedance matching of any audio signal.
The device is equipped with TRS or RCA L/R unbalanced Inputs, XLR balanced L/R OUT, as well as an attenuation selector [0 dB -20 dB -30 dB] for both left and right channel input signal.

It is also possible to take repetitions of the input signals through the convenient THRU connectors on the front panel, while the Ground button eliminates possible hums on both output signals.
