Marantz EQ-10
Little is documented about the Marantz EQ-10. What the record shows is fragmentary, pulled from scattered period listings. There is no sustained review and no surviving manual. It appears to have been a graphic equalizer - a fifteen-band unit, according to one listing in High Fidelity (1981, p.278). The same listing noted a ±12 dB range in each band, 20k-ohm input impedance, and a maximum output of 1V.
The listing also gives a net weight of 5 lbs and dimensions of roughly 3″H x 15″W x 8″D, with a price of $129.98. That places it among Marantz's late-1970s-to-early-1980s accessory components. The company was then under the Superscope umbrella, selling a broad lineup of separates and add-ons alongside its receivers. Whether the EQ-10 was meant to pair with a specific Marantz preamp or receiver isn't recorded.
Beyond that listing, almost nothing else survives. No service manual excerpts, no owner anecdotes, no production-year confirmations. If you have one on a shelf, the known specs are worth jotting down:
- 15-band graphic equalizer
- ±12 dB range per band
- Input impedance: 20k ohms
- Max output: 1V
- Weight: 5 lbs net
- List price: $129.98 (circa 1981)
It's a thin entry. Not every model in a major brand's catalog left a full paper trail.
