Hi!  This is for a ART Levelar Professional Tube Compressor Vacrol Tube Leveling Amplifier Personal Processor.   Ships in original box and includes ac power cord and manuel..  It is in good condition and wasn't used that much.  Thanks for bidding!  Manufacturer specs are below:


From the designers of the award winning Tube MP comes the latest in the Personal Processor Series of world class signal processing: The Levelar. The Levelar is a single channel leveling amplifier. Similar in design philosophy to the classic tube limiters, the Levelar utilizes a VCA-less design for premium performance. The Tube Compressor's design features electro-optical (Vactrol ®) and vacuum tube electronics, which delivers classic sound without the "old" noise. Ask any audio engineer what makes a great compressor/limiter and they will tell you - "sound". The classic pieces each had a sonic "flavor" that made them popular. One of the main complaints about many contemporary compressor and limiter designs is that they are "life-less" or "dull" sounding. This is primarily due to the action of the VCA (voltage controlled amplifier). Classic compressors and limiters had a "sound" that isn't available elsewhere. Tubes alone were not responsible for this sound, but rather the complete circuit design. The Tube Compressor from ART has characteristics reminiscent of these classic pieces, yet offers a "sound" you simply cannot get elsewhere.

The Tube Compressor is as simple to use as a contemporary compressor. The primary difference is that it is used (as the classics are) to level out the signal as opposed to altering the complete dynamic range. The Tube Compressor offers both compression and limiting. Due to its very fast attack and release response times, the Tube Compressor provides the "classic" punchy and transparent characteristics of the "LA-" type levelers and offers a finely tuned auto setting which behaves like the classic stereo modules, providing a smooth, loud, and fat sound.
The particular device is in perfect condition and working order. It has seen little use, and has never been used outside of a studio environment!
