Denon SC-350 (1977)
The Denon SC-350 is a 2-head, single-well stereo cassette deck from 1977. It's a straightforward, no-frills design from Denon's late-1970s lineup — a DC servo–driven transport paired with a single record/playback head and a separate erase head, handling 4-track, 2-channel stereo at the standard 4.76 cm/s tape speed.
It supported both Type I (normal) and CrO₂ tape formulations, with frequency response rated at 40 Hz to 15 kHz on chromium dioxide tape (±3 dB) and 40 Hz to 14 kHz on normal tape. Dolby B noise reduction was built in, bringing signal-to-noise to 58 dB (at 5 kHz with Dolby engaged); without it, the deck managed a still-respectable 56 dB. Wow and flutter was rated at 0.13% WRMS, and power consumption was a modest 12 watts.
The SC-350's line input sensitivity was 0.1V, with a 0.3mV mic input, and line output was 0.38V. Physically, it measured 420 x 120 x 218 mm and weighed 4.5 kg. A period reference in Mix Magazine (December 1983, p.87) mentions the SC-350 among record playback equipment popular with serious audiophiles, though without detailed commentary on its performance.
Beyond its specifications, little else is documented about the SC-350. No original pricing, no positioning within Denon's cassette deck lineup, and no owner reviews have surfaced in the available record. It appears to have been a competent, workmanlike deck of its era — one that survives primarily through its spec sheet rather than a legacy of distinctive acclaim.
