PRO MPA II OVERVIEW – FEATURES AND GENERAL
INFORMATION
:
The ART PRO MPA II microphone preamplifier features a new low noise, high performance preampli-
fication circuitry, designed for superior audio fidelity. Building upon the quality and success of great
sounding products like the Pro MPA and MPA GOLD, ART engineers set out to develop the next
generation of professional microphone preamplifier. PRO MPA II is the culmination of years of re-
search and development, and sets a new standard for quality and value. Professional features and
spectacular tone are what make the PRO MPA II a world-class microphone preamplifier. Its impres-
sive feature set includes:
Variable input impedance for flexible microphone voicing (150 Ohms to 2400 Ohms).
Selectable plate voltage
Large VU meters
Front accessible meter trim
Discrete class A input microphone preamplifier
Low noise at low gains
Low THD
Wide frequency response
Front accessible Instrument Input Jack
Very high input impedance
Mid/Side micing support
+4dBm/-10dBV output level selection
Switch selectable Stereo/Dual operation of the output controls
Automatically switches to the instrument input when you plug in
The signal path of PRO 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. The
Mid/Side Matrix switch sums the adjacent channel to decode left and right information following the
gain switch function and before the output level control. The Tube Warmth display monitors the signal
level before the output level control as well. The analog meter monitors the output level of the PRO
MPA II before the +4/-10 switch but after the output level control.
The PRO MPA II is an attractively styled processor, with a black anodized front panel and matching
knobs. The switches on the PRO MPA II are backlit and illuminate when depressed.
