USB turntable - Computer Definition
A phonograph turntable that is used to convert tracks on vinyl records into a digital format such as CD audio or MP3. With a built-in phono preamp and analog-to-digital converter, the USB turntable converts the cartridge's analog signal to digital PCM and sends it to the computer via USB. Software in the computer converts the PCM into the required format. Do It Yourself The USB turntable makes it convenient for consumers to convert vinyl collections, but music enthusiasts can connect their own turntables to the computer's sound card. However, a phono preamp is required in the middle to boost the cartridge signal and provide the RIAA equalization normally found in amplifiers and receivers with a phono input (see phono preamp). See turntable, PCM, cassette ripping and VHS ripping.
