Page 12: How Do The Gpi's Work
• Make sure you are connected to the MVS edit port. • If all this fails contact ECHOlab or the edit manufacturer for further assistance. 8. How do the GPI's work ? There are four GPI inputs on the MVS. Three are dedicated and one is command selectable. -
Page 13: How Do I Adjust Subcarrier Frequency
9. How do I adjust subcarrier frequency ? If an MVS, operating in genlock, fails to subcarrier lock or falls out of lock after warming up, the internal subcarrier frequency may need to be adjusted to match the genlock reference source’ s frequency. For optimum adjustment, the following procedure should be performed after the MVS chassis and the genlock reference source have been allowed to reach normal operating temperature. -
