Square Faceplate, is used with Valcom “Handsfree”
Talkback Page Control units.

Mounting
Valcom offers three backboxes (not included) for
mounting the V-1961 speaker. The VB-S11
(surface mount), VB-A13 (angled surface mount)
and VB-R12 (recess mount) are all designed to fit
the V-1961. Mount the backbox according to the
instructions provided with the backbox. After
mounting the backbox, connect the cable to the
screw terminals on the amplifier. Mount the
speaker baffle to the backbox with the hardware
provided.
IMPORTANT
The speaker is no better than your ears. If
you cannot carry on a conversation at normal
voice levels over the required talkback
distance, then the talkback page equipment
will not function satisfactorily.
Use common sense when mounting a
talkback speaker. The speaker should be as
close as possible to the area where talkback
is desired.
It should not be mounted close to or pointed
at, noise producing equipment such as fans,
air conditioners, machinery or compressors.

Talkback not recommended above 80dB
TYPICAL REPLY DISTANCE CHART
Maximum Talkback Reply Distance
Limitations
Two talkback plus 40 one-way amplified
speakers maximum per zone when mixing
talkback and one-way paging.
800 feet maximum cable length to speaker
from page control.
NOTE: Do not split pairs to speakers.
Do not use talkback in noisy areas (80dB or
greater).
Valcom recommends that the total number of
speakers per talkback zone be limited to two
talkback and forty one-way self-amplified speakers.
The reasoning behind this recommendations is
simple. Whenever a page is made into a talkback
zone, the paging party will hear audio from all of the
talkback speakers in that zone. If a zone contains
more than two talkback speakers, the talkback
audio from the “extra” speakers will impede the
quality of the talkback audio from the desired
speaker. Additionally, there are limits to the
number of talkback speakers that a page control will
actually drive. Ideally, if a page were made into a
talkback zone, all of the speakers would simply act
like “one-way” speakers except for the one that is
closest to the paged person
FIGURE 1: TYPICAL CONNECTIONS
NOTE: Do not connect this speaker directly to a
25/70/100 Volt amplifier as damage to both the
amplifier and speaker may occur.
A V-1095 may be used to allow the use of
Valcom self-amplified speakers on 70V speaker
lines.
