standards, and that it’s tone, functionality
and performance will satisfy even the most
discerning user.
Like the Digital MPA, the MPA Gold features
Variable Input Impedance. Variable Input
Impedance is intended to optimize the MPA Gold
for the widest range of microphones. Variation of
the input impedance of a microphone preamplifier
changes the load against which the microphone
has to push. This variation dramatically alters
the performance of a microphone, and creates
numerous sonic possibilities for microphone
performance. The variable impedance control
of the MPA Gold is infinitely variable, as opposed
to steps. This allows users much finer control
over the tuning of the impedance.

The selectable Tube Plate Voltage function
delivers a wide variety of tones. The tube circuit
is differential, and provides the equivalent of a
300V power supply on the high voltage setting.
Not to mention it has very low distortion and
noise. Our normal setting maintains ART’s
classic tube sound (warm with smooth
overload characteristics).

Condenser microphones, ribbon microphones,
dynamic microphones – new and vintage –
all become more versatile and deliver their
maximum performance when they interact with
the MPA Gold’s Variable Input Impedance. You’ll
discover that your microphones will sound better
than ever.

In addition to the VU meters, the MPA Gold has
Tube Warmth LED Metering which measures
the left and right audio channel levels. The
meters act like a normal histogram for the
average signal level and the display holds the
highest LED on alone for one second. While the
average level function attack and release are
measured in milliseconds, the peak function
has a 20 microsecond attack time. Additionally,
the analog meter range is switchable between
-10dB and +4dBU. The MPA Gold’s High Pass
Filter is continuously variable from 15Hz to
150Hz. Many other preamps have a fixed
switch. This makes our MPA Gold more
flexible audio processor.
