To input or output a composite signal, use a single BNC male connector
to the Y/VID receptacle on the back panel of the unit.
When both the BNC connectors and the 4-pin mini DIN provide simultaneous video
input, the signal with the highest priority for video output is highlighted in blue in the
table below:

Audio connections — A 3.5 mm, 5-pole captive screw connector for
audio input and output (see the figure at right). Input and output can
be mono or stereo and can be balanced or unbalanced, depending on
the wiring connections (see figure 5).

See the note on page 5 for important information about preparing and connecting
wires to captive screw connectors.
The table below shows the initial gain differences between audio input/output
connectors, using captive screw connectors. The unbalanced output from the captive
screw connector is half (-6 dB), regardless of input.
Input Output Gain
Balanced Balanced 0 dB (unity)
Balanced Unbalanced -6 dB (half)
Unbalanced Balanced 0 dB
Unbalanced Unbalanced -6 dB
Additional adjustment of audio gain or attenuation can be made using SIS commands
(see page 13).
NOTE: The Audio LED lights up immediately when the transmitter detects an audio
signal 35 dB below the nominal level. It remains lit until the audio signal
drops below that threshold continuously for 10 seconds.
