Details

Controls: Low shelf boost 20/30/60/100 Hz (0-13.5 dB); low shelf attenuate 20/30/60/100 Hz (0-17.5 dB); high peak boost 3-16 kHz (0-18 dB); high shelf attenuate 5-20 kHz (0-16 dB)

I/O: transformer-balanced input/output; input impedance ~600 ohms, output impedance ~50 ohms

Notable use: Engineers note it as preferred for kick, snare, bass, piano vs the tube EQP-1A3 for a punchier, tighter low end

Notes: Current maker Pulse Techniques LLC. Same passive EQ front end (input transformer + LC network) as tube EQP-1A3, but solid-state (API 2520) gain stage instead of tubes - flagged tube-vs-solid-state variant, separate row per brief. Basis for the 500-series EQP-500X derivative.
