Question about Audio & Video Receivers

1 Answer

PA Mixer I have a Peavey XR-1200D powered mixer that works ok for a few minutes and then starts to make a loud crackling noise. The noise is before the main master volume and monitor sliders because it can be turned down when they are pulled right down. I haven't been able to source a schematic for this unit on the internet either, even from Peavey! Any hints would be greatly appreciated. Thanx in advance... Gord.

All mechanical switches such as sliders and pots will get noisy after time. They get mildew and tarnish on contacts. Get a can of WD-40 and spray all switches and pots inside. You can do this by inserting the straw nozzle into slider switch slot or pot space where wires and attach. Spray briefly (short burst), then work control to both extremes of travel.

How to fix extra speakers to peavy xr 886 and get the same power to each sperkers not just daisy chain each extra speakers


This powered mixer can only drive 4 ohms a channel...two eight ohm speaker cabinets daisy-chained makes one four ohm load. Ampifier wattage output ratings are usually higher driving four ohms than eight BUT never drive a lower rating than advertised by the manufacturer.

If you need more power than the mixer can provide, connect the "Master Out" or "Mono Out" connections (next to the speaker output jacks) to an external power amp. Connect additional speakers to this external amp and you're done.

I have an old late 70s Peavey PA-400 powered mixer. It's a workhorse that suddenly started doing the following: As soon as you turn it on - both speakers hum pretty loudly, and the back of the PA...


As these units get old, the solder joints can start to fail. Also, come of the components are getting tired. If you have no electronics experience, bring this to a servicer. I typically overhaul these units for about $100 plus parts. In most cases, the parts costis less than $20. These are solid units and you can probably get another 30 years out of it.

Part of the overhaul should be reseating all of the output transistors and replacing all of the heatsink compound as well as cleaning out all of the pots and switches.

Keep us posted.

How do you hook up a peavey pv14 usb mixer to non-powered speakers?


You'll need to provide an amplifier if there isn't one built into the speakers. All the mixer does is combine audio sources and provide a line-level output. A separate amplifier is needed to boost that to speaker level. If you're just using the mixer in a home setting and you have a stereo receiver or home theater system, you can feed the mixer's output to an auxiliary input on the receiver and use the speakers you have connected to that.

I was doing a party iconnect the mic to mixer, they star to talk paralell with music and blow the upper part of speakers, they sound but not any treble


Hi,
What happened is that the tweeter is blown. or a fuse in the speaker that goes to the tweeter has blown. Hopefully that is it.
There are several causes. Here is the theory so you understand how to match an amplifier to a speaker system.
Tweeters have a much lower capacity for amplifier power then woofers do. All professional speakers as well as home speakers reflect this.
You may ask exactly what blew the tweeter?
Usually what destroys the tweeter is not amplifier power but distortion. If someone is overloading the microphone, or the microphone is not trimmed to the mixer. You get distortion. This distortion is what caused the tweeter to blow. The signal must be clean. If you put too much power in, it may survive OK but if you put distortion in, it will more likely blow.
It is no shame for this to happen. I have had it happen to me when mixing a live show. You just have to watch what is happening and not turn things up too loud so the mixer or the amplifier distorts.
Also when doing sound work, the ears of an engineer naturally lower the perception of loudness. Engineers often keep turning up the equipment up more and more during a performance because they have lost the perception of loudness that was there when they started. That is also the reason that many professional studio musicians and drummers loose much of their hearing at an early age.
Hope this helps,
Happy New Year,
Mark

How to connect microphone to Yamaha RX-V365 as a PA system.


Home-theatre receivers don't have microphone inputs. If you want to use the receiver as an amplifier in PA system, you need to use some kind of mic pre-amp or a mixer with mic inputs.
For PA mixer is needed anyway almost every time and all mixers have at least one mic input (with a pre-amp). Mixers have line-level output(s), which you can connect to the analog input of receiver.
Using receiver as an amp in PA has advantage that you have 5 channel amp. When using high sensitive PA speakers (as oposed to less sensitive Hi-fi home speakers), you can get good performance with the power rating of receiver. You could even use 2 separate channels for subwoofers and 2 channels for satelite speakers - but for that you would need a receiver with 5.1 analog inputs and special device called crossover which would divide the output from mixer into low-frequency signal and high-frequency signal which you would then connect to the front and rear analog inputs. But with RX-V365 you can use only 2 channels with analog input

Have a peavey-xr-600b peavey mixer amp. i get aloud hum and noise and cracking when plugging speaker jacks.


Hi chillin884

Not a good sign. Something has gone wrong with the output stages of your Peavey. It is not a good idea to continue plugging it in as damage may occur to your speakers. I suggest you take it to a decent music gear repair guy for a look see and give you a quote to repair These heads, like all Peavey gear, are pretty solid and worth repair. Sorry to be the bearer of bad news like this, good luck

regards
Graeme
