Onkyo ht r508 amp is not able to receive audio signal from ps3 through optical out

Have you assigned the optical input to the input you are attempting to use? Scroll through all inputs and you may find the sound is there. If not check the optical cable is working (red visible light) Also a big one is making sure in your ps3 settings that the setting for audio out is set to 'optical'

ADCOM7500 how to use it?

Good gift. It is a 5 channel power amplifier and I do not recommend to connect any sources directly to it. Now you need to buy a preamplifier/ receiver from Adcom GTP series or other brand to connect you dvd player, cd player, cable box, playstation etc. you need 5 good speakers to get your surround sound (or 2 for stereo)

Onkyo TX-SR805 Amp isnt projecting the picture through my Sony kdl46xbr. i am recieving sound but no picture. Reconnecting direct from source to TV and no issue so the problem is with the amp. HDMI symbol...

I have a 607 by Onkyo and you have to assign imputs to the imput selector. I don't know if your model uses the same, but if it does press setup and select input assign then select HDMI imput to see what it is set to.

Hi i have a krf-v5030d and i am having trouble woking out how to connect it to my panasonic 37'' plasma th37px70b and my sky plus box can you help me please .thanks john

Hi John,

I have the same amplifier, a Sky + HD box, an LCD TV an surround speakers. We wont go into the Wii, PS3 and PC also hooked up. Essentially the best way to go (whatever you connect up) is to split the video and audio signals.

Sky: The Sky box has an audio outputs (left and right channel) found at the back of the box. You get some twin audio cables, plug into the back of the Sky box and the other end into the Kenwood Amp (for example we use Video 1). This means that the sound from Sky can be found on Video 1 on the Amp.

You take the video signal (picture) from Sky using a SCART cable and put into the back of your panasonic TV. This does mean that you can watch a picture without the sound and listen without a picture. The Amp remote controls the sound, the Sky / TV remote controls the picture.

You may need to tinker with some settings on the Amp, for example on the front of the Amp you will find a source button, toggle through the 3 or 4 options to give you the right sound. But essentially that should be it. The same process is used for any other things you want to add, like a DVD player, a games console and so on.

Hope this helps.

Regards, Mohammed

No picture, have sound

Sounds like the video cable from the receiver to the projector is disconnected. Check the video output cable on the receiver and the video input on the projector. If they are connected all the way then unplug them and plug them back in to see if that works. If it does not there is probably a break in the cable somewhere or something not set right on the output or input on the receiver.

Using a tube pre amp with my CA Azur 640A?

There are many answers to your questions but Ill have a go with the basics...
Audio connections should be matched.... its called Frequency impedance,.... to get a signal along wires or cables (or Fibre) the Impedance of the cables and wires must be matched to the device they are connected to transfer the signal along the cables without distortion...

Manufacturers provide many sockets on the input side of amplifiers and preamplifiers to allow the consumer to connect various devices of different impedance.

They label these inputs like CD, or Tuner, or PHONO etc etc,

That means if you have a CD player it must be plugged into the CD input socket then the impedance will be correct and the sound will transfer along the CD cables correctly, without distortion..same with the Phono input etc...
You will find on the sound output to the speakers terminals are also labelled 4-6ohm, or 8-10ohm, these are the impedance expected for the coil ratings of the speakers them selves and its important to get the correct speakers to the correct out put terminals...

In your case all you have to do is follow these simple rules and all will be say you have a squeeze box well there probably isnt a port labelled squeeze box so you need to experiment and try out each input port for the squeeze box to see what input gives you the correct sound output...Watch the Phono inputs as these are very sensative to input sound levels and must be treated very carefully as they have a double stage of sound amplification and as such you need to have the volume right down when connecting up the Phono inputs then increase the volume carefully after the cable connections are completed.

If you follow these rules then all will be well,,,,there is no difference if the Pre amp or Power amp is valve or transistor or FET or has IC outputs to the speaker the same impedance rules apply..just treat it as a box with input and output terminals and all the impedance will be taken care of for you...if you read the lables...

You need to connect you signal source to the Preamp inputs the out put from the Preamp connects to the power amp input then the power amp output goes to the speakers. this is a basic configuration for sound systems, there are other variations but are outside this discussion.

No sound through the speakers...

It may be the PS3
you have to select Optical Out 5.1 etc first.
That PS3 is not user friendly at all.
