Marantz T100 (1980–1983)

Name: Marantz T100
Brand: Marantz

The Marantz T100 was a solid-state digital tuner made in Japan from 1980 to 1983. Marantz was moving its tuner line at the time from the analog dials of the 1970s to the quartz-synthesized digital tuning that would define the early 1980s. It covered FM, MW, and LW bands. FM sensitivity was rated at 1.4 µV, and signal-to-noise ratio at 70 dB.

English documentation on the T100 is thin. Most of what survives comes from German sources, where the tuner was sold as the "Digitalradiotuner." The known specifications from period listings are an FM frequency response of 40 to 15,000 Hz, channel separation of 40 dB, THD of 0.3% on FM, and a fixed output of 400 mV. The chassis used 17 transistors and 8 diodes.

The T100 was introduced at 845 Deutsche Mark. It appears to have been a mid-range digital tuner in the late-1970s/early-1980s Marantz lineup, sitting below the top-tier Model 2130 that Audio (October 1978, p.79) grouped with competitors like the Kenwood KT-8300 and JVC T-3030 in a tuner roundup. The T100 itself doesn't appear to have gotten the same review attention in the English-language press. Its obscurity today likely comes from a modest production run and sales mostly in European markets.

Information on this model is thin, but the core facts are consistent across the German and international databases that document it.
