Effectivement je viens de lire cela dans la notice de l'ampli (http://www.voxamps.co.uk/downloads/vt-manual.pdf) :
6. PHONE OUT Jack
Connect your headphones here. The output is Mono on the AD60VT and Stereo on the AD120VT.
IMPORTANT NOTE: Connecting the headphones here mutes the internal
speaker(s).
7. LINE OUT Jack(s)
This Output carries a cabinet simulated signal for connection to a soundboard or recording console. The AD60VT has as a single, Mono LINE OUT jack while the stereo AD120VT boasts a pair - Left (L) and Right (R).
