¼" Output Jack; Power Jack - Art Tube MP Studio V3 User Manual

mixer, go into the mixer's line in or insert inputs and not necessarily
into the mixer's microphone input, unless the mixer can pad that input's
level.
¼" OUTPUT JACK
The ¼" Output jack is unbalanced and should be used for sending
signals to amps, processors, or other unbalanced configurations.
Both balanced and unbalanced output connections may be used
simultaneously. This is particularly useful when using the Tube MP
Studio V3™ as a direct box for instruments or line level signals. Make
sure that both pieces of equipment connected to the Tube MP Studio
V3™'s outputs are connected to the same earth ground, beforehand,
to avoid electrical shock.
If you experience a grounding hum when using both output connectors
(one to a console, one to an instrument amp) simultaneously, a ground
loop may be the problem. To remedy this problem, disconnect the
ground wire (pin 1) from the XLR cable plugged into the Tube MP
Studio V3™'s output. This interrupts the ground path and therefore
breaks the loop.

POWER JACK

An external 9 Volt AC adapter powers the Tube MP Studio V3™. Plug
the adapter into the PWR jack and then into a power outlet. Only use
the adapter that came with the Tube MP Studio. If the adapter ever
becomes damaged, immediately discontinue use. They can be
purchased locally or directly from ART. Just make sure that you specify
9 Volt AC (not DC), at 800 ma.
