Pultec EQP-500X 500-Series 2-Band Program Equalizer

Taking the solid-state EQP-1A3-SS and EQP-1S3-SS and condensing them into a convenient 500-series form factor, the Pultec EQP-500x is a 2-band program EQ sporting a solid-state API 2520 op-amp for the gain stages. The EQP-500x otherwise features the same parts and specs as the EQP-1A3 and offers 30 to 100 Hz shelf boosting or attenuation, 1 to 16 kHz peak boosting, and 5 to 20 kHz shelf attenuation.
