You have one of two solutions.

One: you have the speaker ohm load lower or higher than the amplifier will support. You should check the ohms rating on your speakers vs. the amplifier. Make sure you match up the rates for proper operation. You can also try out a different set of speakers and see if they work properly.

Two: You have an electronics failure within the amplifier. You need to obtain the electronic knowledge and schematics for servicing your unit or bring it to a repair facility in your area.

Just as an FYI.... double check your speaker cables and make sure that neither the left or right is shorting together. Make sure the bare conductors are not touching anywhere. A pinched or damaged speakers wire can also cause the symptoms you are talking about.

Not a good brand to buy its low end. However thats an old model so you would have to keep looking on Ebay for something like that.

Why does stereo amp cut out at higher volume


You seem to have the answers to your question. I would just resolder the connections anyway without checking. If it solves the problem you have saved yourself a lot of money. If it doesn't follow the other steps in order of cheapness!

I have a technics SU-v500m2 amplifier connected via the aux input to my pc, i wish to link another amp to the same input, is this possible, and if so how?


Let's establish which is the IN and which is the OUT here. The PC is a Line Level source so its OUTPUT would feed one of the amp's Line Level INPUTs.

What's the second amp going to do in your scenario? Something other than the normal stereo channels; something multichannel (if your PC supports it); or just more speakers supported for the PC to feed?

An RCA Y-connector pair would share the stereo output of the PC with multiple Line Level destinations.

If a second amp with its own volume control is intended to share the same two channels with the SU-V500 it could also be slaved off the back of the SU-V500 wih an RCA patch pair exiting the Tape 1 or 2 REC(OUT) jacks. The second amp would receive full-volume audio from whatever source the SU-V500 is playing. Just don't activate the selected Tape monitor on the SU-V500 or you will cut off the source to both amps.

Technics amplifier su-v98, cuts off at 22-24 desibls


The most common cause of this is defective coupling caps inside. These allow some DC voltage to pass through to the final amp stage. This DDC voltage is detected by the protection circuit and the unit shuts down. This unit will require service. Please note that this should be a simple and inexpensive repair. The cost should be less than $10 for parts.

Amp cuts out


most of these type systems have feedback path which shuts down the system once there is excess heating in the regulating transistor... i think there must be something getting shorted when u turn the volume up.....
