Valcom V-1961 Quick Start Manual

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.

SYMPTOMS
ACTIONS
No sound in page mode
Check tip and ring for audio at speaker.  Check tip and ring for audio at control unit.
Low sound in page mode
Check volume controls at page control.
Poor listening in talkback
mode
Check talkback volume control at page control. Set control
where audio is clearly audible.
Check presence and polarity of LED input signal.
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.
