CONNECTIONS
Despite the Tube MP Studio V3™’s sophistication, it is easy to interface the
unit with a wide variety of equipment. All inputs and outputs, are located on
the rear panel. Standard ¼” and XLR inputs and outputs make patching
simple.
¼” INPUT JACK
The ¼” Input jack is for instrument and line level inputs. It has a high
input impedance to minimize any loading effects on instrument
pickups. It can also handle up to +22 dBu signals for line level signals.
Though not normally suggested, both input jacks can be used
simultaneously, in a pinch, to sum two signals. The signal present at
the XLR jack will tend to attenuate the signal of the ¼” input.
XLR INPUT JACK
The XLR Input jack is primarily intended for microphone input, and as
such can furnish Phantom Power when needed. It can handle up to
+14 dBu signals, which is the hottest signal you would get out of any
microphone. For even hotter input signals, you should use the ¼” input
jack. The XLR Input jacks medium input impedance is extremely flat
over a wide frequency range, which allows it to be musically neutral to
virtually any microphone (one of the Tube MP Studio V3™'s lesser
known secrets).
XLR OUTPUT JACK
The XLR Output jack of the Tube MP Studio V3™ is active balanced.
You may use it in an unbalanced configuration without harm to the
output circuitry. The XLR output can provide a hefty signal level
(+28dBu) at a low impedance, so make sure that you do not overdrive
equipment with sensitive inputs. When using it on the front end of a
