Do you have a question about the BOSS KATANA-50 Mk II and is the answer not in the manual?
Questions and answers
Katana mk 11-no out put to th espeaker -headphone jack works but not to speaker
The Roland BOSS KATANA-50 Mk II has a REC OUT/PHONES jack, which likely disables the speaker when in use. If there is no output to the speaker while the headphone jack works, check if a plug is inserted into the REC OUT/PHONES jack. Removing it should restore speaker output. Additionally, verify that the POWER CONTROL switch is not set to STANDBY and that the MASTER and VOLUME knobs are appropriately adjusted. If the issue persists, further inspection may be needed.
