On the LM-2U, four channels of conversion are provided from high-level balanced signals (typically +4 or +8 dBm) to low-level unbalanced signals (typically -10 or -20 dBV).
Gain adjustments for each of the four channels are readily accessible from the front panel, in order to accommodate a wide range of signal amplitudes.
