ONKYO M282 AMP seems to have lost all mid and low range

I think I blew it out. Heavy usage for about 6 hours, I noticed it was REALLY HOT earlier in the evening. Now, I only get low volume, very high freq range sounds...

Is it salvageable?

It's probably salvagable but I doubt it will be cheap or easy. Most likely you have one or more ruined output transistors. If you're into taking things apart and soldering, it might be easy for you. Just look
for abnormalities on the transistors, usually a little hole in the center of them or blistering. Replace those and you'll either have it back to sounding good or much closer to it. Most output transistors do not fail without showing visual evidence of it.

I would think anything decent would work just fine. Records do not have the Dynamic range CD's do. Also most units just use a simple RC circut to do the RIAA comp.

Distorted sound / fuse blows off when changing amp class.


The class A switch adjusts, via an optocoupler, the bias on the output transistors.
I would check the standard bias and class A bias adjustments.

M282 onkyo amplifier died during a movie. During one of the heavy bass scenes (a thunder storm), the amplifier just died. I verified all of the connections, and they are good. Tried pressing the on off...


If your speakers are not in good condition you may have floated the cones inducing DC feedback into the amplifier, Im not sure if this amp has internal protection fuses, but I would check them and if so replace with same specification fuses. Sometimes we get lucky... Good luck

Thanks for the answer - If we have 3 controls as Bass, Mid and Treble. If we keep those in 12 O Clock position, will the output level be equal. In using the Bass and Treble control only (if we have...


If all are in 12 o'clock position they are "flat" (nothing has been added or subtracted foam input signal) If you only have bass & treble, yes adjusting will affect "mids" but Mids change can go both ways dependent on increase or decrease of Bass and /or treble. By increasing bass you will pull some mids up also. By increasing treble you'll subtract some mids.

System just got hooked a couple months ago and was listing to it loud and the sub quit working no blown fuses and amp light on but no sub it did it once before and had to turn off car to get sub back on


You probably blew out the sub, the larger speakers are more at risk to distortion are high output levels. The amp can no longer maintain its true output and begins passing voltage to the sub and the cone over travels or the winding burns out. You can try gently pushing on the sub membrane to see if it moves in and out easily, it may be stuck and you can free it up. If that doesn't work, remove from system and check the coil with an ohm meter resistance. it should read a low ohm value. If high value, it's blown and you need a replacement. It is also possible you blew the network that sends the lows to the sub and the high to the mid range and tweeters, check the sub first.

Crown CE1000 and CE2000 both clipping with low signals


for some reason channel one of one of our amps started clipping. i first noticed it with the drum kit but it slowly moved to the vocals as well. i haven't noticed this issue before today. what do i need to adjust to keep it from clipping?

I have an ONKYO TX-SV717Pro amp. recently I lost


It could be that you lost the power supply to the surround amp IC or the Ic is defective. It should be mounted on a circuit board attached to the heatsink. Look for poor solder connections first. I don't recall the specifics of this model, but the surround amp IC should be easily located.

Update this with your progress and I'll try to locate the service manual in the meantime.

Connecting an onkyo m282 to a vintage (1994)onkyo tx905 receiver


I have found the solution.

Using an Audioplex SPKCNV Speaker Level To Line Level Converter should resolve the connection issue.

L or R Channel cuttint out


You have a shorted speaker, crossed speaker wires Or a blown speaker. The amp is reacting to the short.

Start with one speaker by itself, unplug the rest. Check the polarity. Run it on the channel that cuts out. can you replicate it? Check the connections on the amp, and see if they are really close to touching.

Absolutely if it happens on both amps, unless you bought both B stock or Remanufacturerd and they have the same problem. This is rare

Hope that helps you!

Onkyo tx904


I think it does really happen that way on some things like that , maybe its the controling IC or a busted resistor inside your amp. and check your speakers too. maybe they are shorting inside that makes your amp malfunction. try too open it or its up to you.
