Hi I have expericed my amp overheat and switch off on two occasions when connecting it to a mixer. It plays ok for a couple of hours but then overheats.
It is connected to the same set of speakers (Yamaha) I have at home and I haven't experienced over heating at any time then. Apologies for not putting any more specifics on the type and size of speakers. If you require this information please let me know and I will get the details.

Re: Amplifier overheating and swtching of
You need to provide me the specs of your amp, your speakers. Impedance important. You are experiencing overload, overheating caused by overload. You have a wider frequency range using a mixer and that affects the output stage of your amp and can cause to fail.
I am from Yamaha service before and they have speakers that has 4-6Ohms impedance only. And you have to know your amp if capable of handling such low impedance. you may not have problem with the power but it should be impedance.
a 6ya Technician can help you resolve that issue over the phone in a minute or two.
Best thing about this new service is that you are never placed on hold and get to talk to real repair professionals here in the US. click here to Talk to a Technician (only for users in the US for now) and get all the help you need. Goodluck!

Hi, When an two channel (stereo) amplifier is connected in bridge mode the polarity of one channel is reversed, for this example say channel B. An identical (mono) signal is applied to both channel inputs.
The output is now connected between the two channel +ve outputs. As channel A's output goes +ve , channel B's output goes -ve, thus doubling the output voltage.
On this Behringer powered mixer, the bridge switch simply connects the power amp section inputs, the required way.
The bridged output is wired to the B output between pins 1+ and 2+ of the 4 pole Speakon connector. (Because usually pins 1+ and 1- are used, stereo operation is unaffected.)
So.... If you connect a speaker from the A output alone then I would expect it to work, BUT if there is already a speaker connected from the bridge output, then what happens will depend on the amplifier design.
At best the A channel will see too smaller impedance, and hopefully shutdown.
This is a Behringer, it has digital (class D) power amps, and it does Not claim any amplifier protection !!!
If the powered mixer works in normal stereo, then it is probably OK.
If it then does Not work in bridge mode it is likely to be the connector wiring.
All the best.
The rule of thumb is you control your audio on the low side. That means you plug your mics, tuners, audio sources into the pre-amp and then the pre-amp into the equalizer/mixer ant finally the mixer into the power amp and the amp into the "large honkin' speakers". The inter connects on the low side (between the source, the mixer and the power amp are usually done with RCA plugs. Use a good quality set of cables to get good tight connections and solid grounding. AUDIO SOURCE?MIXER?POWER AMP--- heavy speaker wire sized to your SPEAKERS.
hi, normally in any amplifiers or preamplifiers the RCA sockets used only for pre input and output. for speaker out always there will be binding post or speaker sockets, u can connect the pre amps RCA output to ur power amps input. there will be seperate connector for speaker connection in ur power amplifier . You didn't specified the make and model number of ur amplifier and pre. need any further help feel free to contact. ok
The Bose 802/901 family uses full-range speakers instead of traditional woofer/tweeter combinations, so they compensate for the response limitations at the extreme frequencies by using severe electronic modification of the program material. Hence, they are a system, functionally inseparable, but the results are outstanding. Consequently, they need a dedicated amplifier so they alone get the processing provided by their electronic component.
I don't have any data on your mixer/amp but if you can't insert the conroller logically between the mixer and its amps then you'll have to get separate dedicated amplification for the 802's, with the controller between the mixer and that amp.
These units are designed to only run the fan when necessary. If the unit is overheating, there is a problem in the detection circuit. This is a relatively inexpensive repair. If you are getting overheating when running at a low volume, it suggests that the speakers are not matched to the amp. In other words, the amp is expecting an 8 ohm load and is being presented a lower ohm load. This makes the amp work harder and generates more heat. Check the speaker wires and make sure that they are not frayed or crossing in any manner. Also, verify that the rating of the speakers is correct.
The Peavey A/B controls are output gain controls. Your mixers stereo output goes into the amps inputs, channels A & B. The Peavey is the output stage to your speaker system. If you you connect the outputs from a power amp to the inputs of a mixer you will blow the mixers input stage, amongst many other things and possibly damage the amplifier too. The bias (Bass, Mid, Treble controls) are on the mixer, not the amplifier. Unless you are using a mixer amp, which you are not. A PA system DOES NOT work in the same way as an intergrated hi fi amp.
Hi There, you need to eliminate all the connection and surplus items around the SUV-460 amplifier to determine if its the amp or not..
That is disconnect every thing then connect just the speakers and an input to the amp like a CD player or radio input. Then see if the amplifier plays OK thru the speakers on both channels and the balance control works fine....If it doesnt then the fault is inside the SUV-460 but if it all works fine than start reconnecting theemixer panel carefully and recheck all your cables and connections. Its a process of elimination to determine if its a "Box" fault or a cable fault...
