This is the RIAA EQ curve that the J33 applies to the turntable signal. The
exact opposite curve was encoded into the signal when the vinyl LP was
pressed.
RIAA PREAMP
An RIAA phono preamp is a device that boosts the signal from
a turntable and applies a pre-dened equalization curve. The
RIAA equalization curve is applied as pre-emphasis EQ during
the cutting of the metal master, and as a de-emphasis EQ on
playback. In other words, a record is cut with the low frequencies
reduced and the high frequencies boosted (pre-emphasis),
and on playback the opposite occurs (de-emphasis). The RIAA
preamp in the J33 provides this required de-emphasis EQ.
The result is a at frequency response, but with noise such as
hiss and clicks arising from the surface of the record itself reduced
(or “attenuated”). The RIAA equalization curve has operated as
a global industry standard for the recording and playback of vinyl
records since 1954.
