Do you have a question about the Harley Benton HB-20B and is the answer not in the manual?
Questions and answers
I have HB-20B Bass Amplifier. I did not use it approximately three years (did not play my bass at all), finally I decided to turn it on, first several seconds everything was OK, the indicator lamp was red, suddenly it turned green (stand by mode), and the amplifier does not work. Can the long pause in operating the amplifier be the reason? Thank you for your answer.
Yes, if there is no signal at the INPUT jack for 30 minutes, the Harley Benton HB-20B Bass Amplifier will automatically enter standby mode. However, it will switch back to normal mode once it receives a signal again.
