Audio and video signals can be switched separately (broken away from each other) via the User Mode screen of the control software. If the signals are switched separately, the LED above the audio input’s button blinks, and the LED above the video input’s button lights steadily.
The labels above the LEDs can be replaced. See appendix B in this manual for details.

6Mix knob (MLS 506 MA and MLS 506 SA only) — Turn this knob to adjust the level of the Aux/Mix audio input. This control determines how much gain or attenuation is applied to the Aux/Mix channel and, therefore, how loud the auxiliary audio sounds. This knob has no function during setup.
There is no physical limit to this knob’s rotation. During mix level adjustment the LCD screen displays the level (shown below), and also indicates when the knob has reached its functional minimum (0) or maximum (100) limit.

There is no physical limit to this knob’s rotation.

8Clip LED (MLS 506MA and MLS 506SA only) — This LED flashes when the audio level for a particular input is too high. If the audio level exceeds the point at which the Clip LED flashes, the audio will be clipped, which results in a distorted output. Adjust the output level of the active source or the input level at the switcher (via the front panel LCD Audio Adjust menu or via the control software) so clipping does not occur.
