output to connect your headphones. 
The output here is a mix of the line-level 
signals reaching the amplifier, and any 
incoming audio from the audio in 
jack[17].
  If you just want to listen and practice 
through headphones, disconnect the 
speaker-leveloutputs[23]fromthe
speaker cabinet. There is no harm in 
playing the PF-500 / PF-800 without 
speakers.
Before putting on headphones, make 
surethevolumecontrol[15]isturned
down, and (if connected) any external 
audio source has its level turned down. 
This will reduce the chance of hearing 
damage due to loud volumes.
