Already answered for DPS-12 in 2011 which suggests a fuse where the power enters, However, your manual mentions no fuse, but 'protection circuitry'. If there is a fuse, it will be inside and on a circuit board. All fuses have the rating on the end cap of glass fuses and on the side of ceramic fuses, which as also colour coded.

It sounds like you may have ripped the passive (the rubber material around the speaker that stretches when the speaker hits. If the passive is not ripped then it may be picking up static, or it could be blown. You can purchase a noise filter fairly cheap and try that.
Sounds like you will need a new amp. Please send your serial number and the complete model number if it is different and I will quote a repair. [email protected]
Replace all the greatest sized capacitors inside are deformed or leaking. can be a 6 pieces because some of them are used parrallell to get double capacity.
The loud humming could be caused by a cable on the input that is not grounded. It could also be caused by some sort of power supply failure. If you need further help, I’m available over the phone at https://www.6ya.com/expert/david_29ad5d1dd86564b0
