V-9963
DIGITAL FEEDBACK ELIMINATOR
GENERAL DESIGN
The V-9963 is designed to eliminate acoustic
feedback. When a page is made, the message is
digitized and saved. Upon completion of the live
page, the message is released for broadcast over
system speakers. (While this page is being broadcast,
another page can be recorded). This eliminates the
offensive squeal of feedback commonly produced by
telephones or microphones when making a page.

INSTALLATION/CONNECTIONS
Cabling
It is recommended that Category 3 or 5 twisted
telephone wire be used in all Valcom speaker
installations. A screw type connector strip is
provided to allow connection of all wiring to the V-
9963.
Mounting
The V-9963 is wall mountable using ½” screws.
Terminal Connection Access
NOTE: Remove the small side panel to access all
controls and terminations. To remove panel, loosen
the two screws holding the panel in place and lift
panel away from the board.
Audio Treatment
NOTE: If the input signal to the V-9963 exceeds
the nominal levels specified, attenuate the signal
with a V-1092. This situation would apply when the
zone output of a Valcom Talkback Page Control is
used as a One-Way Page input to the V-9963.
