Kanto Audio OBI3 Turntable with Bluetooth 5.3, Preamp, and Pitch Control, Matte Green

The signal from the tone cartridge is not very strong, and needs amplification, which is why many sound systems have phono inputs with built-in preamplifiers for record players. If your system doesn't have a phono input, you can get a turntable with its own preamplifier. If your sound system doesn't have phono inputs, use a preamplifier to connect to the inputs used by CD players and changers.

USB turntables and most preamplifiers also have USB outputs that allow direct connection to computers or USB-compatible TVs and home theater systems.
