I/O: Rear-panel XLR mic input per channel; rear-panel XLR line input (switchable per channel); 1/4in TS instrument input (1M ohm); 1/4in Thru jack (isolated, buffered, unity-gain output); XLR output per channel

Notes: 1U dual-channel rack version of the PREQ2 circuit — see PREQ2-500 (500-series single-channel module, same core preamp/EQ circuit), listed as a separate SKU per instructions. device_class 'Channel Strip' is a FLAGGED JUDGMENT CALL (not plain 'Preamp') because the unit combines a mic preamp with onboard LF EQ and Air Band EQ — per instructions' rule that preamp+EQ combos = Channel Strip. Max gain 71dB per channel (20-42dB low / 42-71dB high range, discrete Class-A transformer-coupled front end with nickel-core Mäag-built input transformer). year_intro '2022' is a FLAGGED INFERENCE from a March 2022 Mixdown Magazine article headline ('Mäag Audio introduce the PREQ2 analog preamp and EQ') — not confirmed on maag.audio itself. frequency_response and impedance_ohms not explicitly stated on the product page — left blank rather than guessed. Price ($2,595) is dealer street/list price from Sweetwater (searched Apr 2026), not listed on maag.audio. country_of_manufacture 'USA' inferred (see EQ4M notes).
