ART PRO VLA II

Audio Proz Inv #: 58509

SN 1739 rev 4 modification. With PS MOD version 4 transformer. With deep bass enhancement, tunes transformer installed in vactrol. Voiced compressor to lessen a "crowded" mix in spatial midrange imaging. Transformer and enhancement now comes into mix when 2 LED's are lit on compressor. Super calibration, low noise channel spec matches + .5db over 58 db range. 9+ condition, new. Since people keep asking, I use an equalized transformer with capacitors and resistors �tuning� the transformer voice midrange slightly down is installed into the Vactrol circuit. This circuit now allows more bass depth and impulse response, as well as insures that high frequency and presence will not be compromised excessively. Also a little 2nd and 3rd harmonic is imparted on the audio to give a slightly thicker sound to the low midrange and up, somewhat like a tape recording or vintage tube/ transformer pre-amp. Except now everything is cleaner, less noise and stays calibrated same way every day every hour, you can lightly or heavily run the compressor for dramatic effects.. I've sent out this design to quite a few personal studios and the unit is some what tweaked for Rock and Roll or modern multi-instrument acoustic music. Some may have felt its most effective use is on tracking vocals.. Its really about combinations of mics and other matters when operating together.

Re: International Shipping: We ship internationally often and have yet to encounter a problem or complaint. We are very careful to test the equipment before it’s packed and then to double box the machine with added protection when needed for front panels, etc. We are not amateurs or an ebay store; we know these machines very well and know what it takes to get them to you safely. We use USPS priority internationally which seems to be the cheapest. If you prefer another carrier (you should know who delivers to your area reliably) please let us know. Also please be aware of any tariffs that you may be responsible for upon pick up on your end. International shipping may be expensive but we will make sure it is not a headache on top of the cost. PLEASE NOTE THAT SHIPPING INTERNATIONALLY WILL BE A MINIMUM OF $16 EVEN FOR SMALL PARTS.
