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.

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 Pro-VLA II for use as a mastering tool
• Variable Threshold, Ratio & Output 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 Pro-VLA II For Interface with Professional OR Consumer Grade Components
• Active Balanced XLR And -Inch Inputs & Outputs

Have been eyeballing one of these plus the PRO MPA Pre-Amp for 2 years to replace some 30 year old gear. Finally pulled the trigger on both. Love the VLA. Compresses well and sounds great . Bought this for vocals, acoustic guitars, guitar cabs and aux percussion. Sounds great on all. Pairs great with the PRO MPA Pre-Amp. Love how it compresses my DI bass from the PRO MPA. Great value for money!

This is a great compressor, I would recommend this to anyone who is looking to get into outboard analog gear. although this comp' doesn't handle lows and sub lows well, it does sound great on many sources. Very transparent unless pushed very hard. my next step is to swap the tubes out for something with a little more gain.

Bought and compared this to the original VLA - this one adds a harsh, aggressive high end quality to the signal, whereas the original was buttery smooth and warm. I'll keep my originals, thanks!

I traded my DBX 266 XL in on this unit. The build quality is great. Audio quality is also great. The compressor sounds far more natural than the DBX unit ever did. You almost can't tell that this unit is compressing the audio being run through it, but it definitely is! This is a far more refined unit all the way around. I have this unit plugged into the main insert on my Mackie 1640i mixer. I couldn't be happier for the price!

I have one of these in my live FOH rack. Perhaps a bit unconventional but I love it. Mostly use it for bass with awesome results. Sometimes I like it on electric guitar, too. But bass is where it warms my heart the most. Tried it on lead vocal some but wasn't really a fan. I'm skeptical as to the accuracy of its metering and to how well the controls actually align with the numbers printed on the front. Mildly annoying, but typical for gear in this price range. Can live with it since it doesn't affect the sound. It does have a tiny bit of hiss. Not enough to matter for live sound but enough that I suspect that recording people might care in some uses. My biggest complaint is that it takes up 2U of rackspace. I guess that's normal for a studio, but when it comes to cramming my gear into my tiny car for live gigs, 2U seems like a ton of space just for a mere two channels of compression. I would not put up with this if it didn't sound so damn good on bass. Also, it looks pretty, which is always nice.

Protect your investment with the Long & McQuade Performance Warranty.

Warranty can be a very important factor when making a buying decision. Because repairs can be very expensive in terms of parts and labour costs, manufacturers usually only provide one year limited warranties that generally only cover items that malfunction due to a manufacturer’s defect. With an important purchase such as a musical
instrument or piece of studio gear, however, many people want to have the peace of mind in knowing that their investment will be protected should the product no longer be performing at 100%.

Because of this, Long & McQuade provides our customers with a FREE one-year Performance Warranty on most of our products. The Long & McQuade Performance Warranty supplements the manufacturer’s warranty to ensure that our customers receive complete “no hassle” warranty coverage within their first year.

How does the Long & McQuade Performance Warranty differ from most manufacturers' warranties?

Performance Guarantee - normal wear and tear is covered, so your product will be performing as well as the day you purchased it for the entire duration of the coverage.

Product Replacement - if your product cannot be fixed or costs too much to fix, we will replace it with the equivalent model for no additional charge. If this is not possible, a full refund will be provided.

No Lemon Policy - your product will be replaced should the same problem occur multiple times.

Convenient - easy drop off and pick up of the product at any Long & McQuade location.

Guitar Setup - Guitars purchased at Long & McQuade come with 1 free setup, to be redeemed within 1 year for new guitars and 90 days for used guitars.

Loaners Available - a loaner product may be given while the product is being repaired.

Power Surge Protection - your product is covered even if damaged from a power surge.

Accessory Coverage - any peripheral devices or accessories that come with your product (i.e. foot pedal, case) are also covered.

Commercial Use Coverage - music and recording professionals who purchase gear for “heavy-use” commercial purposes will still be covered.
 

Long & McQuade reserves the right to restrict the purchase of additional years of Performance Warranty.Used products come with a 3-month Long & McQuade Performance Warranty. Some products (i.e. computers, software, cymbals and other items) are covered only by the manufacturer‘s warranty. Consumables (i.e. strings, reeds, woodwind pads, drum sticks, batteries, tubes, cross faders) are excluded as they are designed to be replaced. Accidental or cosmetic damage is not covered. Speakers damaged by overpowering are generally not covered. Our coverage does not provide compensation for loss of use. As of June 2018 the Performance Warranty is no longer transferable. The warranty is only valid in Canada.

-----

Purchasing additional years of coverage

If you are interested in receiving this coverage for longer than one year, you have the option of purchasing additional years of the Performance Warranty. The pricing is as follows:

NEW products: 4% of selling price to double the warranty from 1 year to 2 years. 4% for each additional year.

USED products: 4% of selling price to increase the warranty from 3 months to 1 year. 4% for each additional year. Pricing for used electronic products is 4% of the original new selling price.

GUITARS: 4% of selling price to double the warranty from 1 year to 2 years. 4% for each additional year. $45 maximum. An additional free setup is not included with additional purchased years of Performance Warranty.

BAND and ORCHESTRAL instruments: $40 up to $2,000 selling price. BRASS and STRINGS: 2% of the selling price after $2,000. WOODWINDS: 4% of the selling price after $2,000.

Some manufacturers provide warranties for longer than 1 year; however, these are usually limited warranties that do not provide the same coverage as the Long & McQuade Performance Warranty. Customers interested in more complete and convenient (but not necessarily longer) coverage are still able to purchase additional years of the Performance Warranty.
