a Power connector — IEC power connector 100 - 240 VAC, 50 - 60 Hz
b Phantom Power indicators — Green LEDs light when +48V phantom power is
placed on the corresponding mic/line input. Phantom power voltage is not adjustable
and is only available to Micinputs 1-8.
ATTENTION:
• Condenser mics require phantom power. Dynamic mics do not require
power.
• Never set a dynamic mic to 48 V. Doing so may damage the mic. For
condenser mics, verify the mic will operate safely at 48 VDC.
c Mic/Line 1-8 input connectors — Eight 3-pole 3.5 mm 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 mic level sources. Up to eight mono mics or line
inputs, balanced and unbalanced in any combination may be connected to these
inputs. See the following diagram for wiring instructions.

d Mic/Line 9-12 input connectors — Four 6-pole 3.5 mm 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 mic level sources. Up to four mono mics or line
inputs (or two stereo line inputs), balanced and unbalanced in any combination may
be connected to these inputs.
e Mono output connectors — Four 6-pole 3.5 mm captive screw connectors provide
up to eight balanced or unbalanced connections for mono line level output signals.
