Features

Inputs — These switchers accept 8 sets of TP signals that are input from Extron twisted pair transmitters on TP cable terminated with RJ-45 connectors. Each transmitter creates the proprietary signal from its RGBHV, RGBS, RGsB, RsGsBs, HDTV, component video, S-video, or composite video input. Most transmitters also include either digital or differential analog audio on the proprietary signal.

TP outputs — These switchers output 8 sets of TP signals for use by Extron twisted pair receivers.

TPX 88 — The output proprietary signal includes the encoded video (RGBHV, RGBS, RGsB, RsGsBs, HDTV, component video, S-video, or composite video), but not the audio output by most TP transmitters.

However, if the input TP link originated from an MTP transmitter with audio, the output proprietary signal also includes the audio portion of the link.

TPX 88 A — The output proprietary signal includes the encoded video (RGBHV, RGBS, RGsB, RsGsBs, HDTV, component video, S-video, or composite video) and audio.

Audio outputs (TPX 88 A only) — If the input TP link originated from a member of the TP family of transmitters (see the table on page 1-3 and page 1-4), the TPX 88 A outputs 8 stereo audio outputs, balanced or unbalanced, on 3.5 mm, 5-pole captive screw terminals.

Audio gain and attenuation (TPX 88 A only) — Users can set the input level of audio gain or attenuation (-18 dB to +24 dB) for the signal that is output locally. Gain and attenuation can be set via the RS-232/RS-422 link or from the front panel. Individual input audio levels can be adjusted so there are no noticeable volume differences between sources (figure 1-2).
