Input and output selection controls and indicators

If the switcher has fewer than eight inputs or outputs, it has fewer input or output buttons and LEDs.

3Input buttons and LEDs — The input buttons and LEDs select and identify inputs.

Alternate preset selection function — The input buttons and LEDs also serve as preset selection buttons and indicators, allowing you to select presets to either save or recall. A more detailed explanation of the presets functions is included in “Using presets” beginning on page 3-16.

4Output buttons and LEDs — The output buttons and LEDs select and identify outputs.

Alternate preset selection function — The output buttons and LEDs also serve as preset selection buttons and indicators, allowing you to select presets to either save or recall. A more detailed explanation of the presets functions is included in “Using presets” beginning on page 3-16.

Alternate audio indication function — On audio/video switchers, the Output 1 through Output 3 LEDs also serve as the input audio level indicators, each indicating a range of 6 dB when lit:

•Output 1 LED off = 0 dB to 5 dB

•Output 1 LED lit = 6 dB to 11 dB

•Output 1 and 2 LED lit = 12 dB to 17 dB

•Output 1 through Output 3 LEDs lit = 18 dB

See “Adjusting input audio gain and attenuation” on page 3-19.

Alternate audio adjustment function — On 8-output audio/video switchers, the Output 7 and Output 8 buttons and LEDs also serve as the Down () and Up () controls and negative (attenuation) and positive (gain) indicators.

See 10 and 11 .

Control buttons and LEDs

5Enter button — The Enter button saves changes when you set up a new configuration. To create a simple configuration:

•Specify video, audio, or both (see controls [ 7 ] and [ 8 ]).

•Press the desired input button ( 3 ).

•Press the desired output button(s) ( 4 ).

•Press the Enter button.

6Preset button and LED — The Preset button activates either Save Preset mode or Recall Preset mode. Save Preset mode saves a configuration as a preset. Recall Preset mode recalls and activates a previously-defined preset. The Preset button indicates Save Preset mode when it is blinking and Recall Preset mode when it lights steadily.

Alternate reset function — This button is also used to clear all ties and presets. See “Clearing all ties and presets” on page 3-25.
