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.
• TheTPX88cannot switch this audio.
• TheTPX88Acan switch this audio and extract it for the local audio connectors.
N The audio distributed by MTP transmitter and receivers is incompatible with the
audioextractionandprocessingcapabilitiesoftheTPX88A.
• TheTPX88andtheTPX88Acannot switch the mono audio that is distributed
by most MTP transmitters and receivers.
• TheTPX88andtheTPX88Acan switch the stereo audio that is distributed by
stereo audio versions of the MTP S-video and composite video transmitters and
receivers, but the TPX88A cannot extract it for the local connectors.
