Audio controls and indicators
3 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.
4 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

Input 2 button and LED. On the SW6 RGBHV A, this button and LED are
secondary functions of the Input 6 button and LED.
6 –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.
7 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.
8 Auto/Manual switch — The rear panel Auto/Manual toggle switch
(figure 3-3) selects autoswitching mode or manual switch mode.
