Kenwood KA 3300D
Little is documented about the Kenwood KA-3300D beyond a couple of late-1980s test reports, but those reports describe an unusual machine. It is an integrated amplifier with a built-in digital decoder. It is the amplifier half of Kenwood's early digital pairing: the companion DP-3300D CD player sent its optical digital output to the KA-3300D's decoder. That put this model right at the company's analog/digital crossover. High Fidelity (January 1988, p.39) treated it as a showpiece of the Kenwood line, specifically of the company's digital direction, while noting that at least one aspect could stand improvement.
Julian Hirsch reviewed the KA-3300D for HI-Fi-Stereo-Buyers (September 1987, p.43). His report shows a well-equipped amplifier. The recorder section had full recording, playback, and dubbing connections for two recorders. You could record one program source while listening to another, and inactive recorders were automatically disconnected from the signal path. The normal CD input accepted a player's analog output. Small buttons handled the subsonic filter, mono/stereo mode, switching between the two AUX inputs, and a 30 dB level cut. Take off the top cover and there is a small internal cooling fan, which was unusual for an integrated amp of the period.
Surviving information beyond those reviews is thin. Known details in brief:
- Integrated amplifier with built-in digital decoder, designed to pair with the DP-3300D CD player
- The DP-3300D offered 16-by-4 decoding and both electrical and optical digital outputs, the latter feeding the amplifier's decoder ($850 list, per High Fidelity, April 1987, p.47)
- Two AUX inputs plus normal CD input; two recorder loops with dubbing
- Subsonic filter, mono/stereo switch, 30 dB mute
- Internal cooling fan
