MTR DI-3 Active Mono DI Box

MTR DI-3 - Active Mono DI Box

MTR DI-3 Active Mono DI Box that also eliminates hum

MTR DI-3 Active Mono DI Box

The DI-3 single channel D.I. box has a mono jack input and link out socket, a ground lift to eliminate hum loops, a three position attenuator for accurate level matching, and a balanced 600 ohm XLR output. The active electronics have a purely resistive high input impedance, and so do not colour the sound. Both models can be powered in 3 ways: by a 9 volt battery, phantom power from the desk (or an MTR PPS-48), or an external 9v regulated power supply.
