ART PRO VLA II Compressor - Not Bad AT ALL

[jesse g]

I wanted an additional compressor in my hardware rack but I didn't want to break the bank on it.  I started watching YouTube videos to see what folks were purchasing that worked well but didn't cost a lot and offered dual ins and outs.   I came across the ART PRO VLA II Compressor and started to investigate further.  This is not a bad compressor to use mainly on vocals, but it can be used on other things as well. 

I know this Compressor has been out for a while, but I never considered it before with all of the big name compressors floating around.   Nice Job ART!   Currently $400.00 +Tax

Haven’t used it but it has some good reviews.  Is it a full voltage tube?

i have an old ART DPS. dual mono tube mic pres. spdif out (if wanted),

it uses starved plate tube setup, my guess is PRO VLA is the same.

 

the DPS sounds great! i still use it sometimes on certain tracks where i want more color.

Alan,

 

Information from the ART website  (Keep in mind that the tubes in this Compressor doesn't have much to do with the  sound coming out of the compressor, so changing them wouldn't make much of a noticeable  change,  however, others may differ)  ?

Overview

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.
