Question about Onkyo M-501 Amplifier

Open Question

Why does My Onkyo M-501 amp causes static in one channel?

I took this into an entirely defernet system. Different Pre-Amp, differnt interconnects, different speakers, different CD Player. It does the same thing. Took it to a repair place and they said it is fine. I brought in and tested it again in both entirely different systems. Still does the crackling, static in one channel. Seems to be the left channel. Any ideas? I will take it back to the repair shop and it would be nice if I gave them some direction as they did not fix it the first time! Thanks, Ken.

SOURCE: Onkyo Subwoofer Pre Out Problem

May not necessarily be the out put, discontect the sub from the receiver and see if it still makes a hum, Making sure that you turn auto on, off on the sub woffer.
If it still makes a hum, then you have a earthing problem, you can get a earth filter put on your internal wiring in your home, or you can remove the earth pin on your sub woffer

SOURCE: garbled / feedback sounds from powered subwoofer

The surround processing portion of the unit has a problem. In either stereo or direct mode, the digital procesing is bypassed. This could be just the surround processing IC, but that IC may not be available as a separate part. I would suggest that you bring this unit to an authorized Onkyo service center for an estimate.

SOURCE: i need speakers for my Onkyo A-911M integrated amp

A+B speakers = 4 channels 2 right 2 left

100 watts/4 = 25 watts per channel

RMS watts / channel = 25 x .707 = 18 watts/channel which is your average consumer stereo system

I would use 8 or 16 ohm speakers (not 4 ohm) -- almost any set of stereo speakers will "work" -- these will be 8 ohm and about 5 watt minimum / 40 watt max thereabouts

What kind of pre amp do i need to operate my parasound HCA-2205A high current power amp


Any preamp should work. A preamp goes into your system between the amp and the other components which plug into it- CD player, FM tuner, Turntable.....etc. It's takes their output signal, processes it as my be Volume, bass, treble... and then send a sufficient signal to the amp to drive the amp to power your speakers. As long as the preamp output is enough for your Amps input any will work as most will be.

B&K AVP2000 left channel not working


Yes amps buzz when something gets near them - say a pen or probe and if you know what it is safe to touch a finger! Fortunatly for you the left channel is the same as the right. So if you believe it's the pre-amp work backwards from the where the power amp connects to the pre-amp, going through the pre-amp stage by stage - prodding the parts. Remember a buzz in the right a buzz in the left! No buzz in the left but one in the right fault found!
Ignore the power supply it's nothing to do with that as it's common to both channels.

Can I conect an Onkyo M-501 power amp to an Onkyo A/V TS xr601 receiver?


HI,
You will not be able to connect the M501 To the TXSR 601 AVR because the AVR does not have any pre out puts except subout.

Erratic volume from new turntable thru used amp


First detirmine if it is only the turntable that is causing this problem, by connecting something else to another terminal. If that works fine it will be the cartridge preamp that is causing the problem. From what you describe it sounds like an IC that is playing up.
If the other device plays up as well as the turntable, I still suspect an IC, but this time in the main pre-amp. The reason I suspect an IC is that by the sound of things both channels are playing up and therefore it has to be somepart that has both channels going in and out of it- thus IC!

I have 1 center channel pre-out on back of my kenwood receiver. how do i hook it to the inputs on onkyo m-282 amp and then to center channel speaker?


Unfortunately can't connect it that way. The pre out is only meant to go directly into an amplifier that has all of the same inputs (front/rear, center and surround), not a standard receiver. (Pre amp to amp only, not pre amp to receiver) If your Onkyo doesn't have all the same inputs as your Kenwood preamp has outputs you will just use your standard left/right outputs from the Kenwood to your Onkyo input (CD, Tape, Phono,DVD etc) then use the outputs (front/rear, center and surround) from your Onkyo receiver and connect directly to your speakers..

2005 Pontiac Sunfire aftermarket audio system install


You can go to Walmart and in the stereo/speaker department they have dash kits for different vehicles.Just read the box to determine your vehicle. Also, they have amp kits for different wattage amps, but if you had rather buy each item you will need, a Power Wire (to the battery 4g or 8g), a ground wire (to the chassey), a remote wire that should run to a wire from your cd player saying remote (any size is fine), speaker wire (14g or 16g is fine) a set of RCA cables, and if your cd player dosnt have RCA jacks you will have to have a converter.

Ford KA Right speaker broken


Hello jump_in_the_, You need to determine if the problem is in the speaker, the wiring or the CD player. It appears that you have already eliminated the CD player, so it must be the wiring or the speaker itself. Connect a known good speaker and see if it works. If it does, then the speaker is bad and needs replacement. If it doesn't, then the wiring is faulty. In that case, run a new wire directly from the CD player plug harness. Hope this helps.
