Standard output connections
The two Output 1 outputs, consisting of five BNC connectors and a 15-pin
HD connector, output the identical video signal and the same sync format.
The two Output 2 outputs are also identical to each other.
4 Video output BNC connectors — Connect RGB video displays to these two
sets of female BNC connectors. Figure 2-6 shows how to connect the various
video formats.

Video output 15-pin HD connectors — Connect RGB video
displays to these two female 15-pin HD connectors.
5 Audio output connectors — Connect audio devices, such as an audio
amplifier or powered speakers, to these two 3.5 mm, 5-pole captive screw
connectors. The connectors output the selected unamplified, line level audio.
See figure 2-7 to properly wire an output connector.

CAUTION
Connect the sleeve to ground (Gnd). Connecting the sleeve to a
negative (-) terminal will damage the audio output circuits.
CAUTION The length of exposed wires is critical. The ideal length is 0.2" (5 mm).
• If the stripped section of wire is longer than 0.2", the exposed wires
may touch, causing a short circuit between them.
• If the stripped section of wire is shorter than 0.2", wires can be easily
pulled out even if tightly fastened by the captive screws.
By default, the audio output follows the video switch. Audio breakaway,
commanded via the front panel, the Ethernet link, or the RS-232 link, allows
you to select from any one of the audio input sources. See chapter 3,
“Operation”, chapter 4, “Programmer’s Guide”, chapter 5, “Switcher
Software”, and chapter 6, “Ethernet Operation” for details.
