output jacks.
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!
