In our Hifi store selection you will find RIAA equalizers and other turntable accessories. If the device to which the turntable is connected does not have a separate turntable connection, a separate RIAA equalizer is required. An RIAA equalizer is needed to correct the frequency filtering performed on the LP in the recording phase and thus to restore the frequency response to its original form. Some vinyl players have a built-in preamplifier, but it is often lower in quality and poorer in terms of connections and adjustments than stand-alone hi-fi equipment.
