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 as a direct box for instruments or line level signals. Make sure
that both pieces of equipment connected to the Tube MP Studio’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’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. 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.
