Transfer vinyl to laptop with vintage audio system ?


Dec 8, 2016
Have vintage rack audio system with speaker wire outputs to stereo. Passive speakers. Want to record my vinyl collection to CD. How do I interface the speaker wire connectors to the laptop's USB? Understand some adapter may be needed - will appreciate pointers and URLs.

I know a USB turntable is the easiest solution but would rather avoid that extra cost. Besides, real engineers don't look for the easiest solution ... :)

Follow up, to clarify. I am starting at the audio system output which is a *speaker terminal". Check Wikipedia for a description and picture. What adapter(s) will connect this to a USB port on my laptop? Laptop has relevant capture software.
