Output Control The Output Control sets the output level of the DPS IITM. 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. 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. DIGITAL CONTROLS Digital Level Knobs The digital level knobs control the input gain to the digital converters of the DPS IITM. 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 DPS IITM. When used in said manner, the analog signals of both channels in the DPS IITM automatically go into the digital converters. On the back of the DPS IITM 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 DPS IITM 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 DPS IITM is working at. By cycling through the various settings, displayed by the upper LED row, one can use a variety of sampling rates. When the ADAT setting is used, the DPS IITM syncs to incoming ADAT clock on the ADAT input. If the ADAT LED is blinking, the DPSTM has failed to find a valid ADAT clock. When the LED is solidly lit, it has found an acceptable ADAT clock signal. When EXT is selected, the DPS IITM looks to the Word Clock input and synchronizes itself to that. If no word clock signal is present, the LED will blink informing you of that no valid word clock signal is present.
