Output Switch; Phantom Power Switch - Art Project Series User Manual

OUTPUT switch

The Output switch controls the output level at both output jacks.
The Inst. position is intended for applications where the ¼-inch output connects to an instrument input and/or
the XLR output connects to a Mic input on a console.
The Line setting provides more gain and maximum output level at both jacks. This is useful when connecting
the output to recording gear.

PHANTOM POWER switch

The Tube MP/C can power any microphone needing +48 volts DC phantom power. Consult your microphone's
documentation to see if phantom power is required to power it. Phantom power is turned on and off with this
switch and supplies power to pins 2and 3 of the XLR input jack. It is best to have phantom power turned off when
connecting microphones to the Tube MP/C. Note: Be sure to turn down or mute the output of the Tube MP/C
when engaging or disengaging phantom power. Additionally, when disengaging, allow 30 - 45 seconds for the
power to completely dissipate. Most microphones will make a sound like air leaking from a tire when phantom
power is disconnected, but some can make some very nasty low rumbles and whines as well. Another note:
Most dynamic microphones (we haven't run across any) should not be affected or damaged if they are plugged
into the Tube MP/C when phantom power is turned on. However, if the mic doesn't need it, don't use it. Some
things are best left untested!
