Important Notice for CL Series & R Series (August 6)
With V1.60 firmware, we found that CL consoles may partially lose HA gain control of R series units after being powered on for a long period of time. We have released the new firmware V1.61 in which the serious problem was fixed, and strongly recommend to update your CL/R series units with V1.61.
We sincerely apologize for the inconvenience.
Guess I now have new plans for tomorrow afternoon,
