Connect weaker wires between speakers and receiver. Positive to positive and negative to negative for best sound. Connect turn table RCA jacks to receiver PHONO input, L & R. Connect devices to power and set receiver to PHONO, go.
It sounds like you didnt hook the negative to the negative and the positove to the positive. Thats the only way that will happen. Or if you put to big of speakers on the amp
The four speakers are split into two groups left and right. You connect the positive terminal on the upper left speaker to the positive terminal on on the bottom left speaker. Then repeat process connecting negative to negative on the same two left speakers. Then connect one wire from the upper left positive to the positive connector on the jack that is marked 4ohm LEFT on the plate attached to the rear of the speaker cab. The do the same connecting a wire from the negative terminal to the negative terminal on the same left jack. Now repeat the process on the right side in exactly the same way this time connecting to the 4ohm RIGHT jack. The switch that is in-between the two jacks can be set for either channel or for both together for stereo at 8 ohms HOPE THIS HELPS
Optical is the clearest information you can get.
Its pure light!!!!
Sony bravia has a optical out, plug that into optical in on your Receiver.
reciever should have a dedicated sub woofer lead out.
obviously goes to the subwoofer
then just your speakers, i'm assuming you know to match wire colour of speakers to colour of the rear of your reciever. that is red to red, black to black??
If by chance your wires are not red and black, red is positive on your receiver, black is negative.
The receiver outputs for speakers will be written so you know which two outputs(red and black) go to which speaker.
Make sure you match positve to positive and negative to negative, otherwise your speakers will
sound real dull and you won't know why.
If you want the speakers wired in parallel, then just make sure positive(red) to Positive(red), and negative(black) to Negative(black) .With 2 speakers, just jump from one speaker to the other....positive red to red, and negative black to black..
Connect the speaker output of the reciever to the input of the speaker. Make sure you connect negative receiver output to negative speaker input and positive receiver output to positive speaker input.
Most common for all car Stereo wire color coding are:
Solid RED wire = +12V Solid Black wire = negative ( - ) Solid Yellow wire = +12V (power ON /OFF) can add additional toggle switch for switching on and off the car stereo
Solid blue wire = Power antenna
the rest of the wires are for car speaker having positive and negative polarity. note: for the speaker connection wires, all the solid colored wires are positive side (+) of speaker. those solid colored wire with stripe black line are for negative side (-) of the speaker
A positive sign must be attach to positive side or red color of reciever
a negative sign must be attach to negative side or blk color of a reciever
on parallel connection.
1.Check your receiver first, and if you can see the wires in the back,
2.Test your speakers, you can use 9v battery and find out which wire for which speaker, connect them one by one.
3.If you have floating ground receiver, ( each speaker wire from the receiverhas + and – wires)please be careful, you have to connect them positive to positive and negative to negative, do not let wire touch the ground, otherwise burn out your unit, but if it is a common ground unit, you can connect the + positive side of the speaker and connect all –negative wires together.
One thing to check would be the speaker connections. If this receiver worked before you moved it and only started doing this after it was moved, that could be the source of the problem.
If the speakers are connected improperly it could cause it to go into protect mode after a few minutes.
Also check the speaker wires and make sure you don't have any frayed wire sticking out and touching the chassis of the reciever or shorting together.
The phase control symbol is something I would need to research, I have repaired several of these recievers and do not remember the phase control ever being a problem.
Logic would dictate that something is connected wrong, my first thought is the speakers, but it could be something else. I would go back over every single connection on the back of this unit and double and triple check them all. make sure the positive speaker connections are going to the positive speaker post and negative to negative.
It is also easy to connect the speakers to the wrong jacks on the reciever. You may be bridging a channel or two and that would cause the reciever to get hot very fast and shut down.
If none of this helps you may just have to take it in to a service center. I would reccomend an authorized Pioneer service center. They can at least call Pioneer tech support and talk to Mark, Bernie, or Mike at Pioneer. They are on top of all things Pioneer.
I will be happy to help you further if you need it.
