When I connect the DI output of my new Origin 20c to my recording system (ART USB Dual Pre into Logic Pro on M1 iMac) there is a constant hum. A noise gate set to -30dB just cuts it out. The combo speaker itself is silent. I cannot find any help on the Marshall website!
Thanks for your kind suggestion but I looked at Soundcloud.com and all I can see are tracks by various artists?
