Input Level from Radio
Analog voice:
The ARD9000 does not provide any sound amplification for analog voice!
Analog voice from your radio is bypassed directly to the ARD9000 speaker
and has to be adjusted with your radions audio gain control (as per diagram
below).
Digital Voice:
Although the factory setting should work with most transceivers, it is possible
to adjust the audio input level manually. This level must be correctly set to
enable effective operation with your transceiver.
If, and only if you are unable to achieve the correct level, then adjust the
input level pot
SP-INI on the bottom side of the ARD9000:
Apply adjustments by observing the OVERLOAD LED as follows:
LED flashing Input level too low
LED off Input level optimal
LED always on Input level too high
