It should have an unbalanced input. Gain variable from 6 to 16dB (which is selected to suit the amount of output you have preset the module to give) and a line driving balanced output which could either be a transformer or 'electronic' output, it is up to you.
The modules have some connections on one of the 41612 connectors which by linking different combinations will 'preset' the amount that the module will lower it's internal operating level.
The lower the level the more headroom but it makes it a little more noisy, it is the usual trade off.
