Blaupunkt TQR-07 (late 1980s)
Documentation on the Blaupunkt TQR-07 is thin. The little that survives comes from a couple of late-1980s equipment reviews, not from Blaupunkt's own literature. It was a car stereo with a tuner and a full-logic cassette deck. HiFI-Stereo (August 1987, p.24) called it the Blaupunkt Berlin TQR07, which suggests it belonged to the Berlin in-dash line.
The manufacturer's spec block, reprinted by Audio (May 1988, p.66), lists FM usable sensitivity of 13 dBf in mono and 45 dB of separation at 1 kHz. On the cassette side it gives a signal-to-noise ratio of 52 dB A-weighted without Dolby NR at 120-µs equalization, with wow and flutter rated at 0.1% wtd rms. The same magazine's review (May 1988, p.68) singled out an unusual automatic volume feature. The TQR-07 actually raises the listening level as ambient noise increases, so if you open the windows, the volume goes up on its own.
HiFI-Stereo's reviewer was decidedly mixed on the unit, though the full-logic cassette mechanism drew clear praise. It ran flawlessly and fairly silently, with none of the clunky mechanical noises common to the era. Installation was the main headache. The TQR-07 was the same size as the in-dash unit, so the reviewer mounted the body under the dashboard instead of using the usual under-seat or floor-mat space.
Production years, original pricing and Blaupunkt's own spec sheet haven't surfaced in the archive so far. The dates above are the documented review dates.
