• Connect the two speaker leads to the J2-6 (SPKR 8Ω+) and J2-72
(SPKR 8Ω-) connectors. The connections are polarity independent
• Set the recessed ST MIC switch (connector 9 – next to the DIN clip) to
the ST position using a small screwdriver. The ST MIC switch must be
in the MIC position for all other configurations!
• Make sure the IP7-FX software configuration is NOT configured for Full
Duplex
An example of a TalkBack Speaker is the Visiton FRS8-8.
Speakers
The IP7-FX receives audio from the network and plays it on its speaker. It
can drive one or more speakers, a self-amplified speaker or an analog
amplifier connected to one or more speakers. For best results and to
improve performance, connect the speaker or amplifier to the IP7-FX using
18 AWG wire.
Single 8 Ohm Speaker
To drive a single 8-Ohm speaker, connect the speaker leads to J2-6 (SPKR
8Ω+) and J2-7 (SPKR 8Ω-). The connections are polarity independent.
Amplified Speaker or Analog Amplifier
To drive an amplified speaker or analog amplifier connect the amplifier’s
Audio+ signal to J2-3 (Line Out) and the Ground to J2-4 (GND).
Do not connect the IP7-FX J2-6 and J2-7 connectors to an
unbalanced audio signal. This will cause permanent damage
and void the warranty!
Multiple Speakers
Multiple speakers are typically used if the IP7-FX will be used for
overhead paging. If more than one speaker is connected to an IP7-FX,
all speakers will sound when audio is sent to it.
When driving multiple speakers, it is recommended that a 25/70V
distribution line be used. This requires the optional 25/70V
transformer (part# COMTR25/70-324J) for the IP7 and speakers with
25/70V transformers.
Multiple Speakers using 25/70V transformers
Due to transformer loss, the IP7-FX will only:
• Supply about five watts to the speaker output when using PoE or
12VDC.
• Supply about 30 watts to the speaker output when using 24VDC
