Art DIGITAL MPA Operation & User’s Manual

4, ART Digital MPA™ Microphone Preamplifier The 1/4” instrument input is NOT affected by this control, and remains high (>1M Ohm) imped- ance. Analog Output control The output signal level at the rear output jacks is adjusted by this control. It can provide from +10dB of gain (…

5, ART Digital MPA™ Microphone Preamplifier control. The DMPA takes about 10-30 seconds to smoothly transition from one mode to the other. There is a slight increase in gain in the “High” plate voltage mode. In the “normal” (OUT) position, the tube distortion gradually…

10, ART Digital MPA™ Microphone Preamplifier NOTE: the Input impedance control only affects the cannon connector inputs. The 1/4” instrument input on the front panel is NOT affected by this control in any way. The instrument input impedance is ALWAYS > 1M Ohm. Dynamic microphones are…

6, ART Digital MPA™ Microphone Preamplifier Generally, keep the unit in 24-bit mode (the out position of the switch) unless you are connected to a system that will truncate the signal to 16 bits. The 24-bit mode has significantly greater dynamic range. Sample Rate Control T…

3, Art DIGITAL MPA ART Digital MPA™ Microphone Preamplifier FRONT PANEL CONTROLS Input Gain Control This control optimizes the input signal level before the tube gain is applied. Both Microphone and Instrument input gains remain the same and are affected by this adjustment. Input gain c…
