Harman/Kardon CD 491 Ultrawideband Liner Cassette Deck - Fully ServicedHarman/Kardon
Harman/Kardon CD 491 Ultrawideband Liner Cassette Deck from 1983 in a Champaign Finish sold with its box & manuals. All Heads have been cleaned and belts have been inspected. Internally cleaned including all internal controllers and potentiometers. Cosmetically, it is in excellent condition with some minor markings on the top plate, but nothing very noticeable.
The CD491 is Harman Kardon's most sophisticated design.
Its frequency response is a remarkable 20Hz to 24kHz (±3dB) with any tape formulation.
And with Dolby HX Professional, and its closed loop, dual capstan transport, the CD491 sets new reference standards for high fidelity cassette decks.
Dolby C provides a signal to noise ratio of 75dB. The combined benefits of these performance features allow for accurate recording of more dynamic audio signals than was previously possible.
This is especially significant as more demanding forms of software, such as digital audio, become available.
It has three heads for improved performance and the convenience of monitoring while recording. There is a Sendust record head to withstand high record levels without overload, and a ferrite playback head for extended high frequency response. Both heads are precisely aligned in one housing.
In addition, the CD491 has dual Dolby B and C noise reduction. And its tone generators for bias trim and record calibration allow for alignment of the bias and Dolby level to virtually any tape.
To keep recording pure, the CD491 has a unique meter weighting feature which measures the frequency content of the music. It references the overload level of the tape to a + 3dB meter reading. This allows the user to easily set the recording level as high as possible, without tape saturation. It is backed by a 16-segment peak level meter ranging from -30dB to + 10dB.
The CD491 also features: bi-directional auto search, which locates the next selection automatically. Auto repeat, and auto space for cueing. And for convenience, the digital display functions as a time counter as well as a conventional tape counter.
Don't compare it to any other cassette deck, compare it to the source you are recording.
