Specifications

T
he ProChannel is the ideal signal processing solution for any studio or
critical front of house application. Combining the best of all worlds in
one unit, the ART ProChannel delivers a single Class-A tube microphone
preamp, a 4-band semi-parametric tube EQ and an extremely versatile
optical/tube compressor in one cost effective r
ackmount unit.
VERSATILE COMPRESSION
The ProChannel offers the ability to switch between optical or the
coveted tube compression circuit (a design made popular by vintage
and costly old-school broadcast limiters). While the optical circuit is
smooth, responsive and transparent, the tube circuit is fast, fat and a
bit aggressive, ideal for those times when compression is used for
effect, not just for dynamics control.
FAT & FUNCTIONAL EQ
The four-band parametric equalizer has selectable Q for the two
sweepable mid-bands. As with all design elements of the ProChannel,
these Q options were fine-tuned by some of the industry’s top studio
and live-sound engineers.
MAXIMUM FLEXIBILITY
The ProChannel is truly three separate units in one box. XLR and
1/4-inch inputs and outputs ensure maximum connectivity while true
insert points are provided between preamp and compressor,
compressor and EQ ensuring each component can be isolated and
used independently if required.
Three hand-selected tubes are used in
the ProChannel, one discreet tube per circuit. Versatile selectable
metering ensures maximum control of each component in the
ProChannel signal path.
FEATURES
▲ Professional Tube-Based Microphone/Line Level Channel Strip
▲ Three Independent World-Class Modules:

The Tube PAC is a combination of the world’s most popular tube
microphone/line preamplifier and optical tube compressor. The
convenient table-top design allows for easy placement in the studio or
on the stage with immediate access to all the controls and metering.
In addition to being a tremendous vocal and instrument preamplifier
and compressor package for any live or studio application,
the

may well be the ultimate in tube direct boxes for acoustic instruments
or bass
.
The microphone/line preamplifier stage is based on the proven and
extremely popular

.
It provides over 70dB of gain,
+48v
phantom power, phase reversal, and is capable of warming up any
instrument or microphone source. LED level indicators are provided to
monitor the output of the 12AX7A tube for harmonic content. The
input level controls allow complete control for setting the desired
amount of tube warmth with independent control of the output level
from the compressor circuitry.
T
he tube compressor is a
VCA-less
,
optical design–similar to that of
the
‘classic’ tube compressors. Its ultra-musical sound is ideal for voice
and instrument applications. Threshold, compression/limiting ratios,
adjustable release times, bypass, gain reduction metering, and output
gain controls are provided.
