Notes: Current maker Pulse Techniques LLC. 500-series single-slot module; maker copy says circuit is 'the same front end' as the EQP-1A3 SS line, but the control frequency set given on this page (30/40/70/100 Hz low, 1/2/3/4/5/8/10/12/16 kHz peak) actually matches the EQP-1S3-SS frequency set, not EQP-1A3-SS (20/30/60/100 Hz, 3/4/5/8/10/12/16 kHz) - flagged discrepancy, not resolved with certainty; a third-party dealer source (proaudiodesign.com) states EQP-500X is derived from EQP-1A3-SS. Solid-state, single-slot 500-series - separate row from rack-format EQP-1A3/EQP-1A3-SS per brief's 500-vs-rack rule. rack_units left blank (slot-count based, not rack U).
