Another source has told me that you cannot use the Phono input on a reciever for anything other than a turntable. Is there any truth to this? The reason being:
1. There is no turntable (lol)
2. I have one more source to put onto the reciever and no other inputs available.

The reciever I Have to work with is a generic $400.00 Sony (I don't have the model number)

Neat looking device. should work, but would put lowest quality device into it. without this or similar unit you cannot use that input for anything other than TT

Anyone care to enlighten an aspiring integrator as to why this is? Is TT gain so inherently high that the RCA inputs on amps have a built in attenuator? Sometthing along those lines?

Thanks...

Just as I figured. Thanks for the comfirmation guys. The RIAA converter module would certainly do the job. Seeing as it the VCR I'm trying to integrate I may look into adding a switch. Not as cool as the module but I won't have to wait for it to come from the UK. The customer only uses the VCR rarely. Thanks again.

To answer your question Nickster it's a frequency issue. Anyone who has ever attempted it will tell you what the end result is. As I heard is was loud and painful. Check out the link that technobeam1 left. There's a bit of an explanation there.

It's the opposite, actually.

Phonographs had phono cartridges. Cartridges came as either ceramic (real old, real cheap), moving magnet, and moving coil. The moving magnet system was the most popular. It put out a very low level of signal, and it required equalization (riaa curve) to ensure a linear response. If you plugged in a line level device, you would overdrive the input immediately. If you had a moving coil cartridge, it was even more sensitive, and you needed a pre amp on your pre amp to make it work.

Sigh. Those were the days.....
