Rami VCA 2 balanced channels adjustable or calibrated gains SLIMRACK

VCA200 inserted into an amplification system, allows sound volume to be remote controlled. It comprises two distinct channels which can be used either in stereo by putting two orders in parallel or in dual mono.

VCA200 could, for example, be inserted in a rack between a mixer and the amplifiers; the gain control is offset by an interference insensitive wired link.

Depending on its use, there are two possible types of wiring :

• For manual control, an external potentiometer will be wired between the 10V and the earth (supplied by the VCA200S) (3 care wiring).
• For automatic gain control, voltage between 0 and 10V would activate from automatic audio visual equipment which directly controls the sound level (2 care wiring).

Several VCA200 linked together can adjust the sound of a multi-amplification system (starts to several areas, cinema),with a single overall control.
