• 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, with the same inputs tied to them
as to TP 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 (VGA) input. This feature allows
you duplicates of output(s) 1 (and 2) while eliminating the need for extra
receivers.
•
Extron recommends against tying a local (VGA) input to a local (VGA)
output; the image displayed from such a tie may be overpeaked.
• When either the output or input of a tie is local (VGA), Extron recommends
that the MTP input or output be connected by a minimum of 50’ (15 m) of
TP cable to prevent overpeaking.
• This connector can also output HD component video, component video,
S-video, or composite video if that is the video format that was input.
If the video output is NTSC component video, S-video, or composite video,
set the output to turn off sync stripping. See the Local video output
sync polarity SIS commands on page 4-13.

Mono Audio (local audio) outputs — Connect audio devices, such as an
audio amplifier or powered speakers, to these four or eight 3.5 mm, 5-pole
captive screw connectors. These connectors output the selected unamplified,
mono line level audio. See figure 2-8 to wire an output connector. Use the
supplied tie-wrap to strap the audio cable to the extended tail of the connector.

C Connect the sleeve to ground (Gnd). Connecting the sleeve to a
negative (-) terminal will damage the audio output circuits.

The length of the exposed (stripped) portion of the copper wires is
important.
The ideal length is 3/16” (5 mm). Longer bare wires can
short together. Shorter bare wires are not as secure in the direct insertion
connectors and could be pulled out.
N • Matrix sizes 1616 and smaller have four local audio outputs.
Matrix sizes 1632 and larger have eight local audio outputs.
• These outputs are always outputs 1 through 4 (or 8), with the same inputs
tied to them as to TP outputs 1 through 4 (or 8).
• The audio that is output on this (these) connector(s) is converted from the
tied proprietary TP input signal or the local audio input. This feature allows
you duplicates of the outputs while eliminating the need for extra receivers.
• When an input that is configured as RS-232 is switched to a local audio
output, the output is muted to prevent RS-232 noise on the audio output.
The volume level for each local output can be individually set via the
front panel or serial port control. See chapter 3, “Operation”, chapter 4,
“Programmer’s Guide”, chapter 5, “Matrix Software”, and chapter 6,
“HTML Operation”, for details.
