INSTRUCTION MANUAL
Thank you for selecting Amperes VP7501 in your public address installation.
VP7501 has been designed to function as patch in panel to isolate the local speaker from
the main pa system. This shall allow a portable pa amplifier to be used in a specified area
using the installed speakers ( be it ceiling or box ) without additional units, thus saving the
cost in sound reinforcement setup.
Without sidelining the emergency situation requirement, each of VP7501 comes with built
in emergency overriding relay, thereby emergency paging signal from main system would
be given priority if warranted. Visual LED indicator would be available if this situation occurs,
thus making it different from other patch in panel.

SPECIFICATIONS
NOTE :
1. It is recommended to connect VP7501 before any volume controllers
2. The volume control shown above is an option to installation
3. Overriding LED indicator shall lit when 24V DC emergency signal is present, thereby local amplification is bypassed.
4. Do not terminate wrongly the DC voltage and amplifier signal as this may cause damage to your amplifier set as well
as the patch in panel.
