The DeeJayPRE features an RIAA-type phono preamp circuit housed in a rugged metal case with full patching facilities for connecting it to a phono turntable and mixer. In the mid-1950s, the RIAA (Recording Industry Association of America) established compensation standards. The resulting RIAA preamp has been built into every hi-fi and stereo amplifier with phono or turntable inputs since then.
