Step 4
Cable the switcher for
audio input. Each input
has a 3.5 mm, 5-pole
captive screw connector for
balanced or unbalanced
stereo or mono audio
input. Connectors are
included with each
switcher, but you must
supply the audio cable.
High impedance is
generally over 800 ohms.
Step 5
Connect RGB video displays to
the Output 1 and Output 2
female BNC and 15-pin HD
connectors. Connect the
various video formats to the
BNCs as shown.
Both output connector
types output the same
video signal and the
same sync format.
Step 6
Cable the switcher for audio
output. Each output has a
3.5 mm, 5-pole captive screw
connector that outputs the selected unamplified,
line level audio. Connect an audio device, such as
an audio amplifier or powered speakers.
