5.
After giving VPe adequate time to adapt to the new system characteristics, observe the
spectrum and check for sufficient spectral improvement.
6.
Verify all PA heat sink temperatures at least remain below ambient air temperature plus 50
degrees C, or about 74 degrees C total when the transmitter is operating in a comfortable
room temperature.
To increase efficiency in systems operating below nominal power levels, follow a similar process
to reduce voltage in a PA until PA output power starts to reduce. In combined systems, this
process should start with the highest temperature PAs.
Secondary Audio and Silence Timeout
The SECONDARY AUDIO feature allows switching to an alternate source after the PRIMARY AUDIO is
