INTRODUCTION Thank you for purchasing the Tube MP Studio - and congratulations: You now own one of the most versatile preamplifiers available. Offering a superb level of sound quality, the Tube MP Studio’s hybrid solid state and tube circuit design combined with a straightforward user interface quickly and easily gives you access to all of its features.
INSTALLATION The Tube MP Studio may be used in a wide variety of applications and environments. Self-contained in an all-steel enclosure, the Tube MP Studio is designed for continuous professional use. Because the unit is compact and lightweight, mounting location is not critical. However, for greater reliability we recommend that you not place the Tube MP Studio on top of power amps or other sources of heat. The tube circuitry needs about a minute to “warm up” from a cold power up.
CONTROLS & INDICATORS INPUT CONTROL The Input Control sets the amount of input gain of the Tube MP Studio. Turn the control clockwise to increase gain and counterclockwise to decrease gain. You may control two ranges of gain with this control, +26 to +60dB and +6 to +40dB. Selection of the gain range is made with the +20dB gain switch. +20DB GAIN SWITCH Use the +20dB Gain Switch to set the gain range of the input control. When the switch is out, the Tube MP Studio operates in Normal mode.
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.
POWER/CLIP/LIMIT LED The bi-color Power/Clip/Limit LED lights green after power is applied and with lower level signals. If OPL is not being used, then the LED will serve as a signal clip indicator. It will light red whenever the signal at the tube’s output is about to clip. If the LED is constantly lit, reduce the signal level with the Input gain control, or Activate the OPL circuitry.
CONNECTIONS Despite the Tube MP Studio’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.
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.
OPERATION The main application of the Tube MP Studio is a microphone preamplifier. Plug any microphone directly into either input and set the input and output controls to provide an appropriate level into the next stage of your system. Use the Tube MP Studio as an acoustic or piezo pickup preamplifier to run directly into a console, amp, processor, recorder, or sound card. The Tube MP Studio is ideal for use as a DI box.
