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.

Phantom Power indicators — These green LED indicators light when +48 V
phantom power is placed on the corresponding mic/line input. Phantom power is not
adjustable.
ATTENTION:
• Condenser microphones require phantom power. Dynamic microphones do
not require power.
• Never set an unbalanced dynamic microphone to 48 V. Doing so can
damage the microphone. For condenser mics, verify the microphone will
safely operate at +48 VDC.

Mono output connectors — 3-pole 3.5 mm captive screw connectors provide
balanced or unbalanced connections for mono line level output signals.
