RIAA equalizers

A RIAA corrector, i.e. a turntable amplifier, is needed as an additional device for most amplifiers when you want to use a turntable.

Not all amplifiers have a built-in connection for turntables. In this case, you need a separate turntable preamplifier.
Some separate turntable preamplifiers also offer adjustments to adjust the sound box of your player to work better with the amplifier.
