Power connector — IEC power connector 100 to 240 VAC, 50 — 60 Hz

Phantom Power indicators (mIC +48v) — 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 through 8.
attEntion:
• Condenser microphones require phantom power.
Dynamic microphones
do not require power.
Never set an unbalanced dynamic microphone to +48V. Doing so may
damage the microphone.
• For condenser microphones, verify it safely operates at +48 VDC.
• When a line level source is connected, be certain the +48V phantom
power is off (cleared).
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 and provide phantom
power. 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 or unbalanced in any combination can be
connected to these inputs, (see figure 2).

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) line
level sources, plus mic level sources. Up to four mono mics or line inputs (or two
stereo line inputs), balanced or unbalanced in any combination can be connected to
these inputs.
