Tolerance RIAA-Equalization
The Equalization follows the RIAA Curve within the Tolerance of 0.2 dB in the frequency
range of 10 Hz to 50 kHz. This precision requires a equalization network with a maximum de-
viation of 0.1 %.
FFT Analysis of the RIAA Phono Stage.
Measurement: MC-RCA-Input to Fix-Out. 2 V RMS Output, Frequency 1 kHz
The graph depicts the absence of hum caused by the mains. The RIAA Stage adds only second
order distortion (k2 @ 2 kHz) in the microscopic Level of –100 dB. This corresponds to a
THD+Noise of 0.001 % (weighted).
