Installing Your External Paging Adapter
Step 5: Connect Amplifier and Speaker to Wiring Block
1 Install Amplifier and Speaker
Please follow the installation instructions that
came with your amplifier and speaker.
Note that you may be installing a speaker with
a built-in amplifier. These are called “amplified
speakers” or “self-powered speakers”. In this
case you would not need an external amplifier.
2 Connect Wiring Block to Input of
Amplifier
Connect the input of the amplifier to the indi-
cated screw terminals on the wiring block.
Note that if the input level of the amplifier is
less than -25dBm, you should connect the
amplifier to the BLUE and BLACK wires. If the
input level of the amplifer is greater than -
25dBm, you should connect the amplifier to the
WHITE and BROWN wires.
Note that if you have connected a self-ampli-
fied speaker, you would of course be connect-
ing these terminals directly to the speaker.
Note that TMC does not include any cables for
connecting the wiring block to the amplifier.
This is because different amplifiers have many
different types of input connectors. Some have
RCA jacks, some have 1/8” jacks, some have
screw terminals, and so on. Connector cables
are sold many places, for example Radio
Shack. (For instance their RCA plug to lug
connector is part #42-2450, their 1/8” plug to
lug connector is part #42-2454, and their lug to
lug connector is part #42-2446.)
TMC recommends Valcom model V-1030C
self-amplified speaker. This model expects
input level from -15dBm to 10dBm. Therefore
you would connect this model to the WHITE
and BROWN wires.
Connect these terminals to the external
paging amplifier if input level is greater
than -25dBm
Connect these terminals to the external
paging amplifier if input level is less
than -25dBm
