Orban SC-66A (c. 1980–1981)
Little is documented about the Orban SC-66A. What the record shows is a price, a category, and not much else.
The clearest surviving reference is an Ashly equalizer advertisement from January 1981, which listed Orban's SC-66A at $599 list beside the SC-63 at $369. It was a competitor's ad — Ashly had no reason to invent Orban's numbers — and its placement in that spread tells us the SC-66A sat in Orban's professional equalizer line, even though the ad gives no specs.
The period context is consistent: High Fidelity (September 1980, p.110), surveying studio equalization practice, noted that when engineers needed serious channel EQ on tape, they typically reached for a parametric. Just how the SC-66A fit that description — its bands, controls, whether it was stereo — is not recorded in the sources available.
Known from the period record:
- List price: $599 (advertised January 1981)
- Product type: equalizer, per contemporary ad placement
- Related model: SC-63, listed at $369
