About the MTP DA4 and MTP DA8
The Extron MTP DA4 and MTP DA8 twisted pair (TP) distribution amplifiers (DAs) distribute
a single TP input signal to four or eight MTP receivers. The TP input can be from any of the
following MTP transmitter and switcher families:
• MTP T SV — S-video transmitter (all models)
• MTP T 15HD A — RGB/high resolution video and audio transmitter (all models)
• MTP T 15HD RS — RGB/high resolution video and serial link transmitter (all models)
• SW MTP T 15HD A — Video and audio switcher with built-in TP transmitter
• VTT001 — RGB/high resolution video transmitter
The MTP DAs are part of a system (see figure 1) used for long-distance distribution of VGA
or other high resolution video. The MTP DAs can also distribute audio or a serial link over
TP cable. The Extron Enhanced Skew-Free
™
AV UTP cable is preferred, but Category (CAT) 5
shielded twisted pair (STP), unshielded twisted pair (UTP), and foil shielded twisted pair (FTP)
cable are also acceptable.

Figure 1. Typical TP Distribution System
The MTP DA inputs a proprietary signal on an RJ-45 connector, buffers it, and distributes
four or eight identical proprietary signals on RJ-45 connectors.
