Memory

Audio settings are saved in nonvolatile memory. When the

switcher is powered off, the settings are retained. When the

switcher is powered on, the saved settings are active. The ties

are not saved; when the switcher is powered on it defaults to

input 1 tied to output 1 and input 2 tied to output 2.

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

MAV 62.

3. Ensure that the proper signal format is supplied.

4. Check the cabling and make corrections as necessary.

5. Call the Extron S

Sales & Technical Support Hotline if

necessary.
