Video signal output connections
4 Composite video output connectors — Connect composite
video displays to these two female BNC connectors.
5 S-video output connectors — Connect S-video displays to these
two 4-pin mini DIN connectors.
Audio signal input connections
6 3.5 mm, 5-pole captive screw connectors — Connect balanced
and unbalanced stereo audio inputs to these sockets using
connectors which are included with each MMX SVA switcher
(you must supply the audio cable). See figure 2-8 for an
illustration on how to wire a connector for the appropriate input
type and impedance level.
Figure 2-8 — Captive screw connector wiring for
input
When making connections for the switcher from existing
audio cables, see figure 2-9. A mono audio connector
consists of the tip and sleeve. A stereo audio connector
consists of the tip, ring and sleeve.
The audio level for each input can be individually set, via
RS-232 link, to ensure that the level on the output does not vary
from input to input. See chapter 3, Operation, and chapter 4,
Remote Control, for details.

7 RCA audio connectors — Connect unbalanced stereo audio
inputs to these RCA connectors. See figure 2-10 for an
illustration on how to wire the RCA connector.

Audio signal output connections
8 3.5 mm, 5-pole captive screw connectors — Connect balanced
and/or unbalanced stereo audio outputs to these sockets using
connectors which are included with each MMX SVA switcher
(you must supply the audio cable). See figure 2-11 for an
illustration on how to wire a connector for the appropriate
output type.

audio output
CAUTION Connect the sleeve to ground (Gnd). Connecting
the sleeve to a negative (-) terminal will damage the
audio output circuits.
9 RCA audio connectors — Connect unbalanced stereo audio
outputs to these RCA connectors. See figure 2-10 for an
illustration on how to wire the RCA connector.
By default, the audio output follows the video switch. Audio
breakaway, commanded via the RS-232 link, allows the user to
select from any one of the audio input sources. See chapter 4,
Remote Control for details on the RS-232 connection.
