Input 1 through 4, 6, 8, or 12 buttons — Each Input button selects the associated input for output. A more detailed explanation of the input selection function is included in Front panel operations, beginning on page 3-6.

On video switchers, the Input 1, Input 2, and Input 3 buttons are also used to toggle autoswitch mode on and off. See Autoswitch mode controls and indicator (video switchers) on page 3-5 and items 10 , 11 , and 12 .

On audio models, the Input 1 and Input 4 buttons are also used to toggle executive mode on and off. See Autoswitch mode controls and indicator (audio switcher) on page 3-5 and items 10 and 14 .

On 12-input audio switchers, the Input 11 and Input 12 buttons are also used to decrease and increase the amount of audio gain for a selected input. See Audio controls and indicator (audio switcher) on page 3-5 and items 6 and 7 .

Input 1 through 4, 6, 8, or 12 LEDs — The input LEDs identify the selected input.

On models that switch both video and audio, if audio is broken away, the selected video input is indicated by a steadily lit input LED and the selected audio input is indicated by a blinking input LED.

On audio switchers, the input LEDs also indicate the audio level (attenuation (-dB) or gain (+dB)) of the selected input. See Audio controls and indicators (audio switchers) on page 3-5.
