According to Ten Tec the audio output on the Scout 555 and Argo 556 is
not
a headphone jack. It is a speaker jack and needs a load to get the
audio
amp into a usable level. Put a pad in your headphone jack or (as I do)
listen
through another device like a DSP filter or external speaker with a
headphone
jack.
