pins, 13 and 14.
• For component video, use the R (R-Y) and R return
pins (pins 1 and 6), G (Y) and G return pins (pins 2 and
7), and B (B-Y) and B return pins (pins 3 and 8).
• For S-video, use the R, R return (C-chroma), G, and G return (Y-luma) pins.
• For composite video, use the G pin and the associated return pin. For
additional genlocked video signals, use the R, B, and associated return pins.
• When connecting the local output to a universal input that has automatic
input detection capability, such as input 4 on a DVS 304, the MTPX’s
S-video output is not detected correctly on the input.
• If the video output is component video, S-video, or composite video, set the
output to “No sync processing”. See the “Local video output sync polarity”
SIS commands on page 4-7.

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 2-7 to properly 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.
C 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
selected 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
duplicates the outputs while eliminating the need for extra receivers.
N 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”, and chapter 5, “Matrix Software”, for details.
