I have a SA-5 Amplifier that i need to use offline, ive tried to preset it to AUX (To use a DAB-radio), and it plays. When the day is over, i turned off the radio and hoped i could just turn the radio on the next day. But i need to config the amplifier again with shared network on my phone etc. Just alot of hassle. Is there a way to keep preventing the amplifier to not turn off and have to reset everything?
