The LEDs adjacent to each button (when lit) indicate which input has been selected for output 1. 11 Audio mute — This button mutes audio output 1.
Operation, cont’d Reading the LEDs Reading the LEDs of the MPX 423 A matrix switcher is the primary means of controlling your inputs and outputs. The unit uses a series of LED colors and actions to indicate the status of each group and/or tie. When in audio-only or video-only mode • A lit input LED represents a tie. • The lit I/O LEDs show the signal type (audio or video). When in A/V mode • A lit input LED represents a video-only tie. • A flashing input LED represents an audio tie.

Genlock Sync When switching between inputs in the Video and S-video groups, vertical interval switching is possible. When all input signals are “genlocked” together, the Genlock feature prevents glitches in the video images.
The volume adjustment is speed sensitive. To avoid large audible volume jumps when the volume knob is turned quickly, the volume changes by smaller steps. Audio mute (Output 1 only) The Mute button toggles between mute and un-mute for audio output 1. The indicator LED to the right of the button lights when the audio is muted. If a muted output is not at maximum attenuation, it is disconnected. Press the Audio Mute button again to un-mute the output and return to the previous output level.
Operation, cont’d Mode 3: Holding the Reset button until the I/O LED blinks once (3 seconds) followed by a momentary (<1 second) press turns events either on or off, depending on the current state of the events: • If the events are currently stopped following the momentary (<1 second) press, the I/O LED will flash twice indicating the starting of events. or • If events are currently running following the momentary (<1 second) press, the I/O LED flashes three times, indicating the stopping of events.
