Vintage AudioControl Phase Coupled Activator PCA bass restoration processor / digital restoration system with subsonic filter.

Unit powers on and the front power indicator lights as shown.

This is a vintage home audio / rackmount processor designed for bass restoration, subharmonic enhancement, low-frequency output, external processor loop, and electronic crossover use. Manual references describe this model family as a digital subharmonic restoration system and electronic crossover.

Condition is used with cosmetic wear from age and storage, including scuffs, dust, scratches, and general rack/handling wear. Front panel labeling is readable. Rear serial number sticker reads G 16932. Includes the unit only as pictured. No manual, cables, or original box included.

I have confirmed power-on only unless otherwise stated. Buyer should expect vintage audio equipment and may need cleaning, setup, or servicing depending on their system.

Condition notes:

Powers on; red indicator light visible

Cosmetic scuffs/scratches/dust on face and chassis

Rack handles/ears present

Crossover frequency label area appears blank/unmarked
