Genlock Sync

When switching between inputs, the resulting image change
should be seamless and clean. The MMX switchers reference the
external sync signal on input #1 to synchronize switching during
the vertical interval. This allows vertical interval switching
between genlocked sources. Without the external sync locking
feature, switching between inputs can result in a brief rolling
(sync loss) or a brief change in the picture size.

System Reset

To reset the unit to factory defaults, press and hold the Confi g
button while power is applied. This resets the audio input
settings to unity (0 dB) and connects input 1 to outputs 1 and 2,
audio and video. The audio and video Confi g LEDs are lit.
Troubleshooting — If No Image Appears
1. Ensure that all devices are plugged in and powered on.
The switcher is receiving power if the Power LED is lit.
2. Ensure an active input and output are selected on the
MMX switcher.
3. Ensure that the proper signal format is supplied.
4. Check the cabling and make corrections as necessary.
