[. . . ] V3TM 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!Musicians want to play, not spend hours adjusting knobs. No other microphone preamp is as user-friendly as the DPSTM. VU METER The VU Meter gives an analog representation of the DPSTM 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. 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 DPSTM. 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. -7- DIGITAL LEVEL The digital level knobs control the input gain to the digital converters of the DPSTM. The purpose of the digital level control is to get the loudest possible signal into the converters before clipping starts to occur. The front mounted clip lights easily notify the user before digital clipping occurs. For the optimal input signal, raise the gain until the digital clip lights just start to flicker, then back off on the digital level by a hair until the clip lights go out. One should most likely test this using the hottest signal they will be using (or use the OPLTM feature on the V3TM setting to get your levels just right. ) There are several paths in which audio can reach the digital signal converters. One is the using the analog inputs of the DPSTM. When used in said manner, the analog signals of both channels in the DPSTM automatically go into the digital converters. On the back of the DPSTM there is a side chain. One can either send out the signals to an effects processor, such as an ART Dual Levelar for additional compression, and return it to the DPSTM using the rear TRS jacks on the back. One could also patch directly into the returns off the side chain, and patch something directly to the A/D converters. SAMPLE RATE CONTROL This button controls the current sampling rate the DPSTM is working at. By cycling through the various settings, displayed by the upper LED row, one can use a variety of sampling rates. [. . . ] This warranty is void if the serial number is altered, defaced, or removed.
