Input buttons and LEDs
a Computer inputs 1 through 8 subgroup buttons and LEDs — Select and identify
computer video group inputs.
b Video inputs 9 through 14 subgroup buttons and LEDs — Select and identify low
resolution video group inputs.
The video input buttons and LEDs in both groups have one primary function (❏) and two
secondary (•) functions:
❏ Select and identify an input.
NOTES: • Video outputs in the computer/audio subgroup (
b
) can only be tied
to a computer video subgroup input (
a
).
• Video outputs in the low resolution video subgroup (
d
) can only be
tied to a low resolution video subgroup input (
c
).
• Audio can be tied only to outputs 1 through 6. If you make a video
and audio tie from the low resolution video group (inputs 9 through
14), audio is automatically redirected to tie it and output in the
computer subgroup (outputs 1 through 6).
• See “Creating a Configuration,” on page 24 to identify the
outputs to which audio inputs are tied.
• Select a preset.
• Display the output volume level.
Output buttons and LEDs
c Computer/audio outputs 1 through 6 subgroup buttons and LEDs — Select and
identify computer video group outputs.
d Video outputs 7 through 12 subgroup buttons and LEDs — Select and identify low
resolution video group outputs.
The output buttons and LEDs in both groups have one primary function (❏) and three
secondary (•) functions:
❏ Select and identify computer video outputs, audio output, or both.
• Mute the output.
• (Output 7 and Output 8 buttons only) Select and identify the video format
(composite [Output 7] or S-video [Output 8]) for configurable inputs 11 through 14.
• Display the audio level of the selected input.
