Audio controls and indicators

Audio configuration/save button and LED — The Audio button and LED

enable the user to view and/or change the current audio level setting for each

input. See “Audio gain and attenuation (SW2 RGBHV A, SW4 RGBHV A,

and SW6 RGBHV A only)”, later in this chapter.

Down ( ) button and LED — The button is used to decrease the audio

level for a selected input. The LED flashes each time the button is pressed to

indicated a 1 dB decrease in the audio level. See “Audio gain and attenuation

(SW2 RGBHV A, SW4 RGBHV A, and SW6 RGBHV A only”, later in this

chapter.

On the SW2 RGBHV A, this button and LED are secondary functions of the

Input 1 button and LED. On the SW6 RGBHV A, this button and LED are

secondary functions of the Input 5 button and LED.

Up ( ) button and LED — The button is used to increase the audio level

for a selected input. The LED flashes each time the button is pressed to

indicated a 1 dB increase in the audio level. See “Audio gain and attenuation

(SW2 RGBHV A, SW4 RGBHV A, and SW6 RGBHV A only)”, later in this

chapter.

On the SW2 RGBHV A, this button and LED are secondary functions of the

Input 2 button and LED. On the SW6 RGBHV A, this button and LED are

secondary functions of the Input 6 button and LED.

–dB/+dB LEDs — The –dB and +dB LEDs indicate the polarity of the audio

level setting. See “Audio gain and attenuation (SW2 RGBHV A,

SW4 RGBHV A, and SW6 RGBHV A only)”, later in this chapter.

Audio level indicators (SW4 RGBHV A and SW6 RGBHV A only) — The

Input 1 through Input 4 LEDs indicate a range of 6 dB when lit (Input 1 LED

off = 0 dB to 5 dB, Input 1 LED lit = 6 dB to 11 dB, Input 2 LED lit = 12 dB to

17 dB, and so on). See “Audio gain and attenuation (SW2 RGBHV A,

SW4 RGBHV A, and SW6 RGBHV A only)”, later in this chapter.

Autoswitch mode control and indicator

When autoswitching is enabled, the switcher continuously monitors all inputs and

automatically switches to the highest-numbered input with video sync pulses

present. If video is absent from all inputs, no input is selected.

Auto/Manual switch — The rear panel Auto/Manual toggle switch

(figure 3-3) selects autoswitching mode or manual switch mode.
