[. . . ] For hot line level inputs, set the switch in the out position. PHANTOM POWER +48V SWITCH The Tube MP Studio V3TM can power any microphone needing +48 volts DC Phantom power. Phantom power is supplied to pins 2 and 3 of the XLR Input jack when this switch is depressed. The Tube MP Studio V3TM slowly applies and removes the +48volts, to prevent damage to microphones. Be sure to turn down or mute the output of the Tube MP Studio V3TM when engaging or disengaging Phantom power. Additionally, when disengaging, allow 30 to 45 seconds for the power to completely discharge. 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. -4- Dynamic microphones should not be affected or damaged if they are plugged into a line where Phantom power is present. However, if the mic doesn't need it, do not use it. Some things are best left untested! PHASE REVERSE SWITCH The Phase Reverse switch is provided to reverse the phase of the signal. This switch works on Pins 2 and 3 of the XLR output jack and also reverses the polarity of the ¼ output jack. In the Normal position, " the signal is in-phase. In the Reverse (or "in") position, Pins 2 and 3 are reversed and the signal is changed to 180 degrees out of phase. Besides showing the average analog level, it is sensitive to attack transients. When not using OPLTM, the VU Meter is a great indicator of how hard you are running the tube. It also helps in setting a consistent level as you change mics and instrument sources. -6- The VU Meter also reflects the impact of the OPLTM circuitry on the signal. For example, if the signal is "in the red" on the meter, the meter will reflect the attenuation of the signal when the OPLTM is activated, and the signal is brought out of the "red". OUTPUT CONTROL The Output Control sets the output level of the Tube MP Studio V3TM. When the control is fully counterclockwise, there is no output. Turning the control clockwise increases the level of the output signal. When setting the Output level control, refer to the VU Meter for an accurate level leaving the Tube MP Studio V3TM. -7- CONNECTIONS Despite the Tube MP Studio V3TM'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. [. . . ] Use the Tube MP Studio V3TM as an acoustic or piezo pickup preamplifier to run directly into a console, amp, processor, recorder, or sound card. The Tube MP Studio V3TM is ideal for use as a DI box. Plug the instrument into either input and use the XLR or ¼" (or both) outputs to connect to your recorder, board or PA system.
