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.
