The world over, the OT-2 provides superior signal isolation from local ac and rf hum, and the ultimate in impedance matching. It does a great job of eliminating line level hum/noise. The advantage is this direct injection box converts a 1/4 inch guitar cable line out to a microphone cable and xrl balanced line giving you more to work with as far as incoming signal on the recorders input provided it accepts a common stage mike cable.

The "Ground Lift" function signifcantly reduces the noise and the rest can be taken out with a simple noise gate, on your pedal board or a VST based gate. It's durable, passive (no batteries) and works like a champ. This is a great unit for connecting your laptop to your mixer and would easily recommend this witnkit reservation.
