[. . . ] 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. 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 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. In general, if your sound is "thin" or "out of position", try reversing the phase to correct the problem. V3TM ­ VARIABLE VALVE VOICINGTM CONTROL TM TM The TPSTM features ART's proprietary V3TM technology. V3TM (which TM stands for Variable Valve Voicing), provides optimized reference points to begin the recording process for guitars, bass guitars, synths, acoustic instruments, percussion and more. ART engineers ran our preamplification circuit through a battery of tests and real life studio conditions. Our goal was to create a processor that would allow a user to have presets that were optimized for specific recording applications. We set out to create a preamp that would be nimble enough to handle both violins and kick drums, and nearly everything in between. We wanted to take the guessing out of the equation ­ and that is how we developed V3. It's simple, easy and it works really well. -5- For example, if you are recording an acoustic guitar, V3 has a preset that has been optimized for that instrument. Once the preset is chosen, the user can even fine tune the signal ­ which shows the true power of V3 technology. . . it's tweakable. V3 even features a multi setting, which is useful for a wide variety of applications ­ like overhead micing, broadcast and field recording. This means that it is now quicker and easier than ever to make great recordings!VU METER The VU Meter gives an analog representation of the TPSTM tube signal level. 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. [. . . ] If you need to, give it a twist. . . you'll find the setting for the tone you are searching for! The TPSTM is also 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. Because of it's low noise and excellent tonal qualities, the TPSTM is ideal for running mixes through before recording to DAT, cassette, or even into your computer or DAW. Used as a mastering device, the preamps are capable of adding warmth and gentle tube compression to the signal. [. . . ]
