Mic/Line 1-6 input connectors — 3-pole 3.5 mm double-stacked captive screw
connectors accept balanced or unbalanced mono mic or line level signals. Mic/line
inputs provide gain settings to accommodate consumer (–10 dBV) and professional
(+4 dBu) operating line level sources, plus microphone level sources. Up to six mono
microphones or line inputs, balanced and unbalanced in any combination can be
connected to these inputs. See the following diagram for wiring instructions.
