Behringer XR-2400 (c. 1994)
Documentation on the Behringer XR-2400 is thin. Almost everything known about it comes from a single product announcement in Mix Magazine (September 1994, p.154). There it appeared as the "AUTOQUAD Model XR 2400," billed as an "Interactive Quad Expander/Gate" with a suggested retail price of $659.99. Most quad gates simply packed four independent gate channels into one enclosure, which limited how they worked together. The XR-2400 was meant to be different, with an interactive design and a filter section aimed at real multi-microphone situations. Drum kit miking gets a specific mention. With several close mics, crosstalk between them can confuse conventional gates, and that was the kind of problem this unit was meant to address.
Beyond that listing, the record goes quiet. No manual, full specification sheet, or later review has surfaced in this archive, and the "AUTOQUAD" name does not appear anywhere else among the Behringer pages here. The archive indexes it under synths, but the period source clearly identifies it as an outboard gate/expander.

- Product type: Quad expander/gate ("Interactive Quad Expander/Gate")
- Marketing name: AUTOQUAD Model XR 2400
- Suggested retail price: $659.99
- Documented context: multi-microphone gating (e.g., drum kits) and mic-crosstalk issues
