When I plug my speakers into my peavey amplifier and turn it on, I get a load hum even if I don't have an input source connected to the amplifier. How do I stop the hum?

The type of cable you use plays a big role
on amps check all grounds, how long it is
has a lot to do with it
You may have a bad cap.inside or even on the
input of your plug.

Maybe this will help

Using a ditto2x looper with the peavey vypr1 amp I get noise or static interference. How can I avoid the noise . are some channel settings more suitable than others ?


No idea what a ditto2X looper is.

Amplifiers can be noisy and this can be caused by components or the internal circuitry being faulty or just plain old, dry soldered joints, dirty or worn switches, rotary or slider controls, connecting plugs and sockets, microphonic valves.

Hum loops are common and difficult to avoid so research can help and in addition: -

Ensure all unused inputs are grounded.
Keep input leads to the minimum length especially on high impedance sources and inputs.
Match source and input impedance as closely as possible.

Infinity tss 750 sub-woofer when powered on immediately pulls speaker in and has loud humming. no inputs hooked up, only plugged in to ac power source.


The loud humming is the sound of AC mains - clearly your amplifier is receiving an input from somewhere and possibly into the front end.

The hum could be induced by radiated energy from nearby unshielded equipment, it could be the result of an accidental hum-loop or could be because the amplifier power supply has a fault.

It is usual practice with amplifier construction to ensure unused inputs are shorted to ground by switching or by additional contacts and wiring at the input sockets. High gain high impedance inputs can cause a great deal of unwanted noise if they are not shorted.

I suggest you read the instruction manual and perhaps Google a few hints and tips about amplifiers and stuff.

Connect audio source to the amplifier input, no sound


are you using the 1/4 in jacks or the balanced inputs.

Peavey 8.5c, mains hum on one side of the amplifier, increases and decreases when attenuator is increased/decreased, dont mind getting my hands dirty and getting the soldering iron out. Thanks


Swap the input cables to verify the problem stays with the same side... If it doesn't then repair the input cables or source of the audio. If it stays with the side, SUSPECT that one of the two signal wires (balanced) on the failed side has broken, probably at the input connector. Maybe bad solder where it comes in. The fact that the gain control affects the hum is GOOD as it means the problem isn't deep in the unit. Here is your schematic and service info:

I have a Boston Acoustics VR-500 Subwoofer with a problem. As soon as anything is plugged into the line level RCA jacks, the subwoofer produces a loud buzz/hum. I have tried connecting it to the subwoofer...


I'm thinking you have an open shield ground on the RCA input side. Connecting speaker inputs possibly restores the ground. Try connecting the high level inputs then disconnect the remote end of the cables (floating the grounds).

Then get out an ohmmeter and find that open circuitor or bad solder joint between RCA ground and real ground in the speaker's amplifier. Or.... if speaker ground kills the hum and you want to use RCA Line Level input to the sub, just connect one minus speaker output on your source amp to one minus on the sub's amp.

I feel like a dork asking this question but how do you connect the amplifier to your mixer. I see that there are places for a banna plug however my mixer will not take a 1/4 banna plug.


In case you don't have one, here is a link to the manual:http://www.peavey.com/assets/literature/manuals/80300573.pdf I don't know if you are using a separate crossover between the mixer and the amp but here is the simplest explanation.I just reread your question and I don't even know whether you have a Peavey amp. Run proper cables from the main output of your mixer to the main inputs of your power amp.They will be 1/4"shielded cables or Balanced XLR cables. Do not use unshielded speaker cables to hook the mixer and the amp together.Run speaker cables from the speaker outputs of the amp to the input jacks of your speakers.Make sure the impedance of your speaker cabinets equals or exceeds the impedance rating marked on your amp. Here is the link to the newer model PV2600 manual:http://www.sweetwater.com/store/media/pv2600_doc_manual.pdf Don't use Speakon cables unless your speaker cabinets are equipped with Speakon input jacks. Banana plugs aren't as solid a connection as the binding posts are.

Wish to run sm450v2 Mackie powered speakers thru a Peavey XR8600


The Peavey XR8600 is NOT just an amp, but a powered mixer.

To SAFELY use this with your powered speakers, connect those speakers to the MAIN and MONITOR outputs on the front of the unit with 1/4 inch INSTRUMENT rated cables (NOT speaker cables).

To safely leave the power amps in the XR8600 with no output loads, plug GROUNDING plugs into the POWER AMP 1 and 2 input jacks on the front. This will prevent the power amps in the XR8600 from running with no load which COULD damage them.

Make the grounding plugs from 1/4 inch mono plugs by jumpering the centr aand sleeve terminals of the plug.

Peavey 2600 Low input = Complete Cutout


I'm not quite sure of how the two amps are interacting here, so I'd like to request that you describe the entire hookup. Sending a higher signal from the mixer should not be a problem, but something is wrong in the setup (I think). Please update this with a description of how you have the mixer and amps connected to the speakers. Thanks, Dan

Sunfire Amplifier hum


If it works fine with other inputs then it simply cannot be your sunfire. Next time it happens try reversing the power plug on one of the pieces of equipment hooked up to it and see what happens.

PV 2600, couple years old, light usage. Connected to two PV SP3K speakers. One channel started to cutout somewhat but not all the way, Switched a few input cables, swapped L&R. Then whole amp shutdown....


Hi..

I've worked on similar units.
Things I'd check first :
Dust in the unit.
Weak solder connections /crusty debris stuff on the input jacks or output terminals
Any flex cables soldered in tend to be a problem on peavey amps I resolder all those contacts.
Checking the amp w/o a load IS NOT a good suggestion.
What style output connections are you using?
1/4 inch, binding post, or Neutrik style?
