Audio
All Extron TP receivers receive and output stereo audio. All
receivers except the TP R 15HD A output the audio on both left
and right RCA connectors and on 3.5 mm, 5-pole captive screw
connectors. The TP R 15HD A outputs audio on the captive
screw connector only.

Stereo audio output connectors
— Connect left and right stereo
audio cables between these rear panel RCA connectors and the
output device’s stereo audio inputs.
Only analog, line level, unbalanced audio signals can be
output on these connectors.
8
Stereo audio 5-pole captive screw connector
— Connect audio
devices, such as an audio amplifier or powered speakers, to
these connectors. These 3.5 mm, 5-pole captive screw
connectors output unamplified, line level audio. Figure 2-8
shows how to properly wire an output connector.

CAUTION
Connect the sleeve to ground (Gnd). Connecting
the sleeve to a negative (-) terminal will damage the
audio output circuits.
If only an audio signal, no video, is received, connect a
ground wire between the chassis ground and an earth
ground in the equipment rack or other grounded device.
If the receiver is not grounded, a crackling sound may be
heard in the audio output.

Power
TP R BNC AV —
Plug a standard IEC power cord into this
connector to connect the TP R BNC AV to a 100 to
240VAC, 50 Hz or 60 Hz power source.
If the distance between the transmitter and receiver is too
great for the receiver to power the transmitter, the video
image will be missing, distorted, or noisy, or the
receiver’s Manual/Auto LED will flash. The transmitter
requires a local 15V power supply.
TP R BNC A and TP R AV —
Wire the external 15V power
supply into this 3-pole captive screw connector
(figure 2-9) and plug the connector into the receiver.
The power supply is included with the unit.
