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 an

indispensable tool for tracking, mixing, mastering, dynamic control of

live sound sources or for use in broadcast audio.

The ProVLA II is capable of delivering a far more musical natural

sounding and sonically transparent compression than competitive

units in its class because it uses an opto-electronic circuit, rather than

a 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

Unlik

e typical compression units that use

Voltage Controlled

Amplifiers (VCA’s) to handle level detection, the ProVLA II’s

Opto-electronic design allows a far more transparent and musical

sounding compression without sounding aggressive or un-natural.

his 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 dr

amatic 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 both 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.

FEATURES

▲ VCA-Less Vactrol Opto-Compression Design

▲ Mastering Quality Audio Signal Path with Tube Gain Stage

▲ Enhanced Link Mode – While in stereo link mode, channel 1 level

control acts as a master output level and channel 2 becomes a

balance control between them, optimizing the ProVLA II for use as

a mastering tool.

▲ Variable Threshold, Ratio, Output, Attack & Release Controls

▲ LED Backlit VU Input/Output Level Metering

▲ LED Metering Indicates Both Average Level And Peak Hold.

▲ Accurate Ten Segment LED Gain Reduction Metering

▲ +4dBu/-10dBu Mode Switch Optimizes ProVLA II For Interface

with Professional OR Consumer Grade Components.

▲ Active Balanced XLR And 1/4-Inch Inputs & Outputs

▲ Toroidal Transformer Reduces Mechanical & Electrical Hum
