Connecting an External Sound System (Optional)
The sound from your selected input source goes into the 4000i’s audio board where the signal 
is amplified sufficiently for the levels needed by the internal speakers. However, to send the 
audio signal to an external, unbalanced sound system, connect standard RCA audio cables to 
the audio Outputs on the connection panel. Keep your right and left channel connections 
consistent for correct stereo sound.
NOTE: Because the audio signal from the 4000i is unbalanced, you should connect to an 
unbalanced audio device or a balancing amplifier.
