Enhanced Reverse RIAA 1.5

A reverse RIAA device allows you to attenuate a standard line level source and to equalize that signal according to the RIAA standard. This would be the same equalization that a vinyl record would provide when played on a turntable.
 
A reverse RIAA device is for:
 
- playing line level audio (CD, music player, iPhone, computer, etc.) through the phono input on your amplifier or receiver
- testing your phono preamp using a line level source
 
Update Enhanced Model RRIAA Model 1.5:
 
- a switch allows selection of the reverse RIAA equalizer curve or the reverse TELDEC curve
- RIAA accuracy: +/- 0.05dB (20Hz - 20KHz)
 
Transition points
RIAA:         75µs, 318µs, 3180µs
TELDEC:   50µs, 318µs, 3180µs
