User manual ART TPS II

[. . . ] IMPORTANT SAFETY INSTRUCTION ­ READ FIRST This symbol, whenever it appears, alerts you to the presence of uninsulated dangerous voltage inside the enclosure-voltage that may be sufficient to constitute a risk of shock. This symbol, wherever it appears, alerts you to important operating and maintenance instructions in the accompanying literature. Read manual. Read instructions: Retain these safety and operating instructions for future reference. Heed all warnings printed here and on the equipment. [. . . ] 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 -7- 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. The signal level should average ­6 to 0 dB on the meter, occasionally hitting the clip light on the highest peaks. When the meter is in this range, you are getting the lowest noise and distortion out of the preamp stage. Adjust the Input control to keep the meter in this range. The +20dB switch does not affect the meter, as the switch is part of the tube gain stage. VU METER The VU Meter gives an analog representation of the TPS II tube output signal level. Besides showing the average analog level, it is sensitive to attack transients. When not using OPL, 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. The VU Meter also reflects the impact of the OPL 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 OPL is activated, and the signal is brought out of the "red". -9- OUTPUT CONTROL The Output Control sets the output level of the TPS II. 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 preamp. When setting the Output level control, refer to the VU Meter for an accurate level leaving the preamp. The marking on the output control determines the meter calibration to output level. If the Output control is set to ­10, then the output of the unit is ­10dBu when the meter reads 0 VU. For +4 (pro) systems, set the Output control to +4 and the meter will be calibrated to your system levels. - 10 - CONNECTIONS It is easy to interface the unit with a wide variety of equipment.
