The ADB2 is designed for sending unbalanced signals (up to +40dB) to a mixing console or other professional input device. The unit has no transformer, so stray field pickup is nonexistent. The unit is powered by standard microphone phantom power from 9 - 48VDC and uses discrete low-noise differential drivers to make it very quiet. The unit has two 1/4" TS phone input jacks wired in parallel, a male XLR output jack, a ground lift switch and a three-position attenuator switch.
