Model: Aphex Model 622 Logic-Assisted Expander/Gate

Country of Origin: Designed and manufactured in the United States (Aphex Systems typically manufactured in the USA during this era).

Years in Production: Introduced in the late 1970s / early 1980s and remained in production through much of the 1980s — this era is prized for its classic analog expander/gate designs.

Up for sale is my Aphex Model 622 Logic-Assisted Expander/Gate, designed and manufactured in the United States during the classic analog era (late 1970s through the 1980s). This unit has been lightly used in a clean, smoke-free studio and is in excellent condition cosmetically and functionally.

Why It’s Great:

The Model 622 is a dual-channel expander/gate using Aphex’s logic-assisted circuitry — offering smooth, musical noise reduction and gating. It’s excellent for tightening drums, reducing breathe on vocals, noise control, and general signal conditioning in both studio and live setups.

Condition:

  • Excellent — very clean panel with minimal wear
  • All functions tested and working perfectly
  • Smooth, reliable controls

Included:

  • Aphex Model 622 unit (USA made)
  • Power supply/cable (as shown in photos)

Whether you’re tracking, mixing, or cleaning up signals, this vintage dynamics processor remains a professional-grade tool. Packed carefully and shipped with tracking. Happy to answer questions or provide more photos.

  • Original rack ears included
  • Owner’s manual included
  • Smoke-free / pet-free environment
