Luxman K-321
The Luxman K-321 is a stereo cassette deck, made when Luxman was still building traditional analog tape machines alongside the first wave of DAT decks. Documentation on this model is thin. No production years, original price or owner's manual text appear in the surviving record. The specifications that do exist describe a well-equipped three-head deck.
The K-321 used a three-head configuration (separate record/playback, erase, and dedicated playback heads) with a DC motor and full Dolby B and C noise reduction. Wow and flutter is rated at 0.05% WRMS. Frequency response extends to 19kHz on metal tape. Signal-to-noise is 68dB with Dolby C engaged (58dB with Dolby B). Line input sensitivity is 75mV and output is 0.44V, which are typical for the era. It also shipped with a remote control.
The K-321 measured 452 x 116 x 262mm and weighed 4.8kg, a fairly standard footprint for a full-width deck of the period. Beyond that, the record is quiet. No contemporary review of its sound has surfaced, and no service documentation appears to have survived in the archive.
