[. . . ] Be sure to turn down or mute the output of the Tube MP Studio 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. 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. In multiple microphone applications, mic placement can affect the phase of the signals. If two microphones pick up the same signal from different locations, the result can be a hollow or frequency "shifted" sound. In some cases it may sound as if an instrument disappears if it happens to be 180 degrees out of phase. Depressing the Phase switch can remedy this. In general, if your sound is "thin" or "out of position", try reversing the phase to correct the problem. OPL (PEAK LIMITER) SWITCH Depressing this switch engages the OPL (Output Protection Limiter) circuitry. This circuit precisely and accurately controls the output peak signal level. This FET (field effect transistor) peak limiter has a fast attack for peaks and slow release time. This helps you to prevent clipping or overload of equipment that follows the Tube MP Studio, such as the A/D converters on a sound card or digital recorder, in-ear monitor systems, or live monitoring system. When engaged, the output signal is limited to approximately 0dBu at the ¼" output jack and +6dBu at the XLR output jack, with the Output control all the way up. The VU Meter and LED indicator reflect the OPL circuit's action. -5- 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.
