Values of R7 and C2 have been changed as shown in standard net-work for phonograph playback equalization. Tantalum electrolytic rated at least 20 V is recommended for C2. Network can also be used as inverse RIAA equalizer for testing preamps, with signal applied to terminal 2 and output to preamp taken from terminal 1. New standard extends playback equalization to 20,000 Hz and specifies that equalization be 3 dB down from previous standard at 20 Hz, with rolloff at 6 dB per octave below 20 Hz.-W. M. Leach, New RIAA Feedback Network, Audio, March 1978, p 103.
