18. PHONES: Use this 1/8" TRS stereo
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-level outputs [23] from the
speaker cabinet. There is no harm in
playing the PF-500 / PF-800 without
speakers.
Before putting on headphones, make
sure the volume control [15] is turned
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.
