Make shure your speaker wiring is solid hookup to amp and spekers (NO CROSSED WIRING). Also make shure speakers are not wired in parallel or the speaker impeadance will be to low and amp will kick out.Turn speakers off then hook up headphones and crank up volume then see if amp kicks out.If it does you have an internal overload and needs serviced. If it playes ok then you must have speaker problems or wiring.
GOOD LUCK

Fuse type for onkyo a-9555


The main power fuse for most amplifiers is a fast blow, 125 volt fuse for the US and a 250v fuse in countries with 220v. This unit is 125 watt so the main fuse should be 2 amps or so. The correct fuse size is written on the circuit board next to where the internal fuse was located.

I have Onkyo AV Receiver - HTS-3100 and what is happening is the Amplifier is tripping automatically in the night at 9.00 pm. It is working in the morning without any issues. I have removed all speaker...


I agree that there's something enviromental to this but I'd think you would see lights dimming around the house at the same time if it was a brown-out.

Is there anything on a timer that switches on at 9:00 PM? What would happen if you moved the power to a different source? That may help isolate the circuit that's straining.

Also make sure you're NOT sourcing heavy-power-using accessories from the convenience outlets on the receiver.

I do not see any inputs to connect a subwoofer to my Onkyo A-9555 integrated amp. I would like to know if it is possible to connect it and what kind of subwoofer should I buy for that wit the best...


You amp has no OUTputs for a sub, but if you really want to attach a sub you'll need to get one that is self-amplified and accepts >>>stereo<<< High Level or Speaker Level inputs.

Otherwise your amp's volume control won't also control the sub's volume.

You would feed it full-range audio from the speaker terminals on your amp and its internal amp would use that to develop its own power output for the sub.

Here's one example.

ONKYO HT 502


Protection mode is engaged when a problem is detected internally. Unless you have crossed the speaker wires, the problem is likely to be a defective component or two inside the amp. This is a relatively common fault for all amplifers at one time or another. The typical cause is shorted output transistors. These parts cost anywhere from $5-$15 each and are replaced in pairs. The best thing to do here is to get a detailed repair estimate from a local repair shop ($50 or so) and report the results here. We should be able to walk you through the actual repair with that info in hand. Dan

Amp protection circuit has been activated


sometimes the protection circuit will enable because of a bad speaker i would suggest taking the load off of it by removing the speaker wires and turning it back on. if it stays on take an ohm meter and check the speakers should be between 2-4 ohms load.
