ART Pro Audio Digital MPA-II - Two Ch. Mic Pre w/ A/D Conversion - Manual (Page 5)

2
The signal path of the DIGITAL MPA II consists of a discrete class A microphone pre-amp followed by
a Low Cut Filter, a balanced differential tube circuit with a 20dB Gain switch and then the phase
switch. At this point the signal passes to both the analog output and the Insert jacks. The insert jacks
allow processing of the signal before its’ level is adjusted by the Digital Level control and passed to
the A/D. You can use the A/D converters of the DIGITAL MPA II independent of the analog functions
by simply inserting a signal into this insert point!
The DIGITAL MPA II is an attractively styled processor, with a black anodized front panel and match-
ing knobs. The switches on the DIGITAL MPA II are backlit and illuminate when depressed.
