Notes: Only available as a 500-series module — no standalone rack 'PREQ4' currently sold (confirmed via search). device_class set to 'Channel Strip' rather than plain 'Preamp' — FLAGGED JUDGMENT CALL because the unit combines a mic preamp with a built-in Air Band EQ section, per instructions' rule that preamp+EQ combos = Channel Strip. Max gain (65dB) is lower than PREQ2/PREQ2-500 (71dB) — single preamp stage design, no transformer-boosted high-gain stage. year_intro left blank; earliest confirmed review found dated Feb 2014, so product predates that, but exact introduction year unconfirmed. Price ($749) is dealer street price from Perfect Circuit (searched Apr 2026), not listed on maag.audio. country_of_manufacture 'USA' inferred (see EQ4M notes).
