What tubes are in Art Pro VLA II?
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.
What is a Vactrol compressor?
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.
What are tube compressors?
Tube compressors achieve compression by re-biasing the tube to control the gain reduction. This characteristically imparts a warm smoothness and slight harmonic distortion to the sound.
What are tube compressors good for?
Tube compressors use tubes to apply gain reduction! These types of compressors tend to have a slower response to transients relative to other types of compressors, making them a good choice for instrument or mix buses.
Which compressor should I use?
Determine which one requires the highest CFM at the highest PSI. Add 50% to the required CFM for a margin of safety, and look for a compressor that meets the requirement. For example, if a tool requires 3 CFM at 90 PSI, select a compressor that delivers at least 4.5 CFM at 90 PSI.
What type of compressor is a DBX?
The original Dbx 160 was a hard-knee compressor; later variants included soft-knee versions, but Waves’ emulation is modelled on the original hard-knee design. Blackmer’s design used a VCA built from discrete components as its gain-control element.
When should you use a tube compressor?
Tube or valve compressors are mostly used after recording in order to add warmth to drums, vocals and basses. This effect is caused by small amount of the second-order harmonic distortion which occurs in the final gain circuitry of the compressor.
How many PSI air compressor do I need?
70 to 90 pounds per square inch
Air tools made for general use with portable air compressors typically require 0 to 5 cubic feet per minute (cfm) at 70 to 90 pounds per square inch (psi), whereas with larger tools connected to stationary systems, the requirements usually exceed 10 cfm at 100 to 120 psi.
