unit” requirements of all of the speakers being served from the location.

The selected power supplies simply need to provide enough VPUs for the

speakers and horns connecting to the IDF. Power supplies, unlike

amplifiers, are not zone dependant and may be used to power

speakers in numerous zones without fear of cross talk.

In the example shown, let’s assume that the speakers in zones 4, 5 and 6 will

all be powered from a single IDF. The power supply selected for the IDF

location must be able to provide at least 49 power units.

5) If one-way self-amplified speakers are being connected to a V-TCM

talkback station board simply add a V-LPT attenuator per zone. If one-way

self-amplified speakers are being connected to a XP-TCM12 25V talkback

station board simply add a V-1095A attenuator per zone. Add a V-1094A

preamp if the zone will include more than 40 speakers. V-STX one-way

station board outputs may be directly connected to up to 150 one-way

speakers.

6) As in all systems, there are certain wire length guidelines that need to be

observed. Make note of the fact that multiple pairs of 24 AWG wire may

always be combined, or twisted together, to further enhance the distances

shown in the charts.

7) Remember that the power supplies used with self-amplified speakers require AC

power. Be sure to account for AC outlet availability (of adequate capacity) at all

power supply locations.

Valcom One Way Self Amplified speakers are known for their dependability and

longevity due to the efficient speaker matched amplifier design. This along with easy

system balancing via built-in volume controls and the fact that speakers may be

placed in any zone without common amplifier restriction make them the obvious

choice for Valcom MultiPath applications. Contact Valcom Technical Support @ 540-

563-2000 for additional information and design assistance.
