N A mono audio connector consists of a tip and sleeve. A stereo audio connector
consists of a tip, ring and sleeve. See figure 2-6 to identify the tip, ring, and
sleeve parts of the connector when you are making connections for the switcher
from existing audio cables. The ring, tip, and sleeve wires are also shown on the
captive screw audio connector diagrams, figure 2-5 and figure 2-7.

The audio level for each TP input can be individually set via the front panel
or serial port control to ensure that the level on the output does not vary from
input to input. See chapter 3, “Operation”, chapter 4, “Programmer’s Guide”,
and chapter 5, “Matrix Software”, for details.

larger), set these DIP switches to the Local (up) position to select the
local (RGB video and audio) input. Set the DIP switches to the
RJ-45 (down) position to select the MTP input.

N For best results, use a cable length of at least 50’ (15 m) between the TP output
connector and the receiver.
N See the Inputs connector, item a , in the “Signal inputs” section, for detailed pin
assignments for the RJ-45 connectors.
f
Local Outputs (RGB) connector(s) — Connect o ne or two RGB
RGBHV video displays to these 15-pin HD female connectors
for each output.
N Matrix sizes 1616 and smaller have one local video output.
Matrix sizes 1632 and larger have two local video outputs.
• These outputs are always outputs 1 and 2.
• The video that is output on this (these) connector(s) is converted from the tied
proprietary TP input signal or the local (RGB) input. This feature allows
you duplicates of output(s) 1 (and 2) while eliminating the need for extra
receivers.
N Extron recommends against tying a local (RGB) input to a local (RGB) output;
the image displayed from such a tie may be overpeaked.
N When either the input or output of a tie is local (RGB), Extron recommends that
the MTP output or input be connected by a minimum of 50’ (15 m) of TP cable
to prevent overpeaking.
