The ProVLA II is a tube driven Vactrol®-based Compressor / Leveling amplifier designed to excel in any professional audio environment. Superior performance and an incredible tone makes the ProVLA II and indispensable tool for tracking, mixing, mastering, dynamic control of live sound sources or for use in broadcast audio.
Capable of delivering a far more
musical natural sounding and sonically transparent compression than
competitive units in its class, the ProVLA II uses an Opto-electronic
circuit rather than the more typical design VCA driven level
detection circuit. This VCA-less design coupled with a 12AT7 vacuum
tube in the gain stage makes the Pro-VLA II the ideal dynamic control
device for critical audio applications.
Exceptional signal integrity with
extremely low noise and low distortion is achieved in the ProVLA II
by utilizing a transformerless design throughout.
Vactrol® Technology
Unlike typical compression units that
use Voltage Controlled Amplifiers (VCA’s) to handle level
detection, the Pro VLA II’s Opto-electronic design allows a far
more transparent and musical sounding compression without sounding
aggressive or un-natural. This Vactrol based optical electronic
circuitry is the basic component of the classic highly sought after
compressors of past. Vactrol® design allows the ProVLA II to react
to audio signal in much the same way the eye naturally adjusts to
fluctuations in light levels – smoothly, quietly and almost
imperceptibly.
Soft Knee Leveling
The ProVLA II is a soft knee leveling
amplifier by design. Although capable of providing dramatic
compression effects, the ProVLA II was designed to excel in any
application where transparent, expressively musical dynamics control
is desired.
Comprehensive Metering
Large highly visible backlit analog VU
meters accurately display input and output levels while extremely
fast 10-segment LED’s display gain reduction. For added
functionality, the LED’s display either average level for mastering
& mixing applications or peak hold for monitoring individual
sources when tracking audio.
Versatile I/O
XLR and 1/4-inch TRS balanced inputs
and outputs are provided to ensure the ProVLA II can connect with any
audio source or hardware. A +4dBu/-10dBu mode switch optimizes ProVLA
II I/O for either consumer or professional equipment.
