I've had a green YPK3 for about a year now, but there seems to be a mechanical problem with it. It used to be that the audio jack held itself in pretty well, now it's liable to pop out with the least encouragement. Now when I listen to music it only plays in one channel, that means that sound only comes out of one ear. Is this repairable?

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.
From what I have seen of the green phoenix plugs, is that they have 3 connectors. 1 is right 2 is left and 3 is earth. Most Receivers use RCA phono plugs with leads that have phono plugs each end So you would have to cut off the plugs of one end of the lead and bear the wire then attach it to your green plug. Unless they make adapter leads!
I've tried using the balance for left and right speakers, and when the receiver is acting up with the right speaker having a low volume, I tried moving the balance all the way over to the right speaker. The right speaker volume will not increase in volume but the left speaker will decrease in volume.
Just to clarify, the center and the rear speakers are balanced. The issue only happens sometimes when I first power on the receiver I will have no center channel. If I leave everything alone for a few mins, the center channel will come on.
So it seems to me that something one the receiver is going. The question is, can anyone suggest a physical repair for the receiver for these symptoms?
The Red (right channel) nand White (left channel) RCA plug to miniphone jack is made for audio amplifier with RCA input jacks. The monitor should have Green audio input mini stereo phone jack for the audio input from the PC audio line out (Green mini phone jack).
You will need the shielded audio cable with mini stereo phone plug at both end for the audio hook up.
The answer is yes - and no. By definition, audio sources are encoded or recorded in a specific manner. If I record a stereo signal, there really are no rear channels or center or bass specific channels. To be most faithful to the original, you play back stereo in stereo and 5:1 in 5:1 and so on. There ARE several units designed to "synthesize" additional channels from sources that do not contain all the info specifically. Some multi-channel receivers/amps incorporate such circuits and you can "derive" rear channels from stereo inputs and so forth. If not, you may need an additional box (device) to turn 2 into 4 or 5, 3 from 2 and so on. Your choice but that's how it works.
The black wire serves as common/return for the green/gray speaker wires. Yes, the black wire should also be grounded to the vehicle as it is the power ground and is tied to the chassis/body of the stereo.
As I understand it, this adapter is used ONLY to adapt a standard 2-channel stereo output to the 3, 1/8" plugs of the Dell 5650 5.1 system. These 3 plugs would normally plug into the front, rear, and center/sub outputs on a computer designed to output 5.1 channel sound.
To make this clear, what this means is that the output you get from your 2-channel stereo system, using this adapter with the Dell 5650 5.1 system, will NOT be full 5.1 surround sound...it will be 2-channel stereo signals intermixed so that it plays from the 5650 system through the Dell amplifiers and speakers...nothing more.
This cannot be over-emphasized. The adapter does NOT create true 5.1 sound from a 2-channel stereo output system.
If you are hoping to get true 5.1 output from a 2-channel stereo system, you will be disappointed.
All this adapter likely does is split/mix some of the 2-channel signal into the rear channel, and split/mix some of the SAME 2-channel signal into the center-sub channel, just so you will get some output from those speakers. There may be some low-pass filtering for the sub-woofer input.
It is almost certainly a very simple passive circuit consisting of resistors, capacitors, and possibly an audio transformer or two.
Look for circuit on Do-It-Yourself electronic sites and build it yourself...or you're almost certain to be ripped-off.
