VR7600 Series
volume controllers / patch panel
RACK MOUNTED ZONE VOLUME CONTROLLERS
Most installations may require different volume of sound output at different
zones and do not want the output level being adjusted unnecessarily by
unauthorised person. It is the reason why master volume for each individual
zone are to be located in the control room or at the main rack.
Amperes VR7600 series are available as standard 50 or 100W 100V line per
zone with each panel having 6 zones. Customised rating per zone shall be
available upon request.

VR7600 is usually installed at the last exit point of the rack, ie. after the
speaker zone selector. If speaker line surveillance unit is available, VR should
be installed before the line surveillance to avoid detection instability due to
variation of impedance.
