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 signal connected to input 5

(within the Video group) and input 9 (of the S-Video group) will be used as the

reference signal for switching between inputs during the vertical interval.

Audio

The MPX 423 A is also a 12x2 audio matrix switcher, where any of the 12 inputs can

be routed to one or both outputs simultaneously.

Establishing an audio tie

Regardless of the switching mode to which the unit is configured (single or

separate), the audio behaves like a 12x2 switcher.

To make an audio-only tie, do the following:

1. Select the output using any of the three output buttons. Each of the three

output buttons can be toggled between output 1 and output 2.

In the audio mode the output buttons are synchronized; i.e., the LEDs indicate

the same output number.

2. Select the audio signal mode using the I/O button.

3. Select any of the 12 inputs.

When one of the 12 input buttons is pressed and released, the audio signal of this

input will be routed to whichever audio output is selected.

When establishing an audio tie, please note:

• The two front panel audio controls only control the audio level of

output 1.

• A flashing LED indicates an audio tie.

• When input LEDs and audio I/O LEDs are flashing simultaneously, the

audio and the video signals and not in audio breakaway.

Audio breakaway

Audio breakaway allows you to route the audio signal separately from the video

signal. Any audio signal can be selected with any video signal to one or all outputs

in any combination, simultaneously.

Audio breakaway switching can be done via front panel control, through RS-232, or

via Ethernet remote control.

Volume control (Output 1 only)

Use the Audio Volume control knob to adjust the volume of the audio output. By

turning the knob clockwise, the volume increases at a rate of 1dB per step of the

digital potentiometer. Turning the knob counterclockwise will decrease the output

level.

Control of audio output 2 is available through RS-232 or Ethernet/Telnet only.
