VP7000 Series
volume controllers / patch panel
LOCALISED SPEAKER PATCH PANEL
VP7501 is used to isolate a group of speakers ( ie, in a meeting or
conference room ) from central paging system for local sound
reinforcement by using a separate portable PA amplifier. Once patched to
it, the local speakers shall be routed to the local amplifier output. However
in the event of emergency or important announcement, the local paging
shall be bypassed to allow central paging signal to go through by
activating the built in overriding relay.
VP7810 works similarly but the local source is meant for 8 Ohm speakers,
eg. to broadcast TV signal to a speaker in bathroom by using a mini
amplifier. In event of emergency paging via central PA, the overriding
relay shall allow the incoming 100V line signal to be broadcasted by
converting it to match the speaker's impedance.
