20, 30, 60, 100 CPS (Hz) shelf boost, 0 – 10 dB in 0.5 dB steps
20, 30, 60, 100 CPS shelf attenuate, 0 – 10 dB in 0.5 dB steps
3, 4, 5, 8, 10, 12, 16 KCS (kHz) peak boost, 0 – 10 dB in 0.5 dB steps
5, 10, 20 KCS shelf attenuate, 0 – 10 dB in 0.5 dB steps
*Note: The inherent interaction of Pultec controls affects the step size when both boost and attenuation are applied simultaneously.
