Turntable won't talk to computer via USB


Likes # 0

I have a little device called an EZCap, which enables the phono connectors from my turntable (via a small pre-amp) to be connected to a USB port on my Windows 7 laptop. SIW lists my sound card as NVidia High Definition Audio - which I guess means it's on-board.

Using this method, together with software called Audio Cleaning Lab, I have successfully digitised many of my old LPs.

Yesterday I tried to set a friend up to do the same thing. He has a turntable connected to a Rotel amplifier (both about 20 years old but good quality).

I downloaded Audacity on to his computer. I assumed that his amp would incorporate a built-in pre-amp, so I connected the EZCap to the Tape1 output phonos on his amplifier and plugged it into a USB port on his Windows XP computer. I'm afraid I don't know what his sound card is, but the laptop is a Toshiba - about 7 years old.

Nothing I did would get Audacity to recognise a signal from the amplifier. I tried every permutation of recording and playback device options within the computer - everything just showed a flat line on the recording meters.

I tried different output phonos on the amp Tape1, Tape2, Aux, Phono, including an additional one called "Pre Out" which I guessed to be a direct output from the inbuilt pre-amplifier. None of them would get any response.

I tried connecting up my own laptop instead of his and running Audacity on it. Same result - no movement whatsoever on the meters.

I should add that his turntable setup works fine with speakers connected to the Rotel amp.

Any ideas on how to get his setup working, please?

I thought that EZcap was a video grabber.

If it will not work with both laptops then suggest you need to investigate the output. Which model Rotel?
