Speaker and 600-ohm Audio Output Volume
The speaker volume potentiometer,
R36
, adjusts the signal level to the speaker from the page line. When
600-ohm audio is also connected,
R36
adjusts the volume for both. Use the CLI (Command Line
Interface) to configure the output level when using 600-ohm audio without external speakers. The default
setting is 4 watts from an 8-ohm speaker and 2 watts from a 16-ohm speaker.
WARNING
—Maximum output power may exceed rated speaker wattage resulting in speaker
damage.
To adjust the speaker or speaker and 600-ohm output volume:
1.
Turn the speaker volume potentiometer,
R36,

The speaker emits an audible test-tone.
2.
