Extron Electronics TPX 88 Series User Manual
Setup guide — tpx 88 series, Setup guide — tpx 88 series (cont’d)
This sheet provides quick start instructions for an experienced installer
to set up and operate the TPX 88 Series matrix switcher.
About Audio
The TPX 88 A has local audio outputs on 5-pole,
3.5 mm captive screw connectors. These outputs
always follow the RJ-45 outputs, regardless of
whether the audio follows the video or is broken
away from the video in the TP ties.
N
The TP transmitters and receivers distribute audio in a proprietary digital channel of
the TP link.
• The TPX 88 cannot switch this audio.
• The TPX 88 A can switch this audio and extract it for the local audio connectors.
N
The audio distributed by MTP transmitter and receivers is incompatible with the
audio extraction and processing capabilities of the TPX 88 A.
• The TPX 88 and the TPX 88 A cannot switch the mono audio that is distributed
by most MTP transmitters and receivers.
• The TPX 88 and the TPX 88 A can switch the stereo audio that is distributed by
stereo audio versions of the MTP S-video and composite video transmitters and
receivers, but the TPX 88 A cannot extract it for the local connectors.
Installation
Step 1 — Mounting
Turn off or disconnect all equipment power sources and mount the MTP switcher as
required.
Step 2 — TP inputs and outputs
Terminate up to eight
TP input cable and up to
eight TP output cables as
shown at right. Connect
them between the TPX 88
and the TP input and output devices.
N
The TPX 88 does not support the
remote power capability of some TP
transmitters and receivers.
Step 3 — Connect a local audio
device (TPX 88 A)
Connect up to eight audio devices to the
Audio Outputs connectors. Wire the
connectors as shown below.
C
Connect the sleeves to ground
(Gnd). Connecting the sleeve to a negative (-) terminal will damage the audio
output circuits.
