The NAD 6130 is the newest in a popular series of budget-priced cassette decks that embody the well- known NAD philosophy of equipment design. The goal of this approach is to deliver maximum achievable performance at any price level.

When manufacturing costs must be reduced the savings are made on the outside, by omitting seldom- used features and by eliminating cosmetic frills (elaborately engraved front panels and machine-tooled metal knobs, for example). Most of the manufacturing budget is invested inside-on low-noise circuitry, a high-precision low-flutter tape transport, and a hard permalloy record/play head that produces low- distortion recordings over a wide dynamic range. This adds up to a level of performance, in both recording and playback, that normally is found only in more costly tape decks.

While the 6130 may be a budget-priced machine, it was designed to work at its best with premium- quality tapes, producing first-class recordings. In addition, its wide-range response, low flutter, and very quiet electronics provide a superb playback environment for the many high-quality prerecorded music cassettes that are available today.

The NAD 6130 includes these important features:

DOLBY C-TYPE NOISE REDUCTION

The Dolby C-type NR system was specifically tailored to extract optimum performance from the cassette recording medium. Its development included very thorough psycho-acoustic testing to ensure that the substantial benefits of its noise-reduction cannot be compromised by musically unnatural side effects such as “breathing” (in which the background hiss rises and falls with each musical note). Dolby C NR operates on the same fundamental principles as the universally accepted Dolby B NR system, but its circuitry is approximately three times more complex, and it produces two dramatic improvements in recording performance.

Much lower noise

Dolby C NR provides a full 20 dB of noise reduction over a broad range of frequencies, virtually eliminating background noise (hiss) as a potential annoyance Increased high-frequency headroom. The Dolby C NR circuit contains a special “anti-saturation” network that eliminates dulling of the high treble frequencies at high recording levels-a problem that has traditionally limited the fidelity of cassette recordings, Together these two improvements yield a major increase in useful dynamic range, just what you need to cope with the wide dynamics of today’s digital recordings. Further details on the performance of the Dolby C NR system are on the reverse side of this page.

QUIET ELECTRONICS

The benefits of Dolby C NR could be wasted if the recorder’s circuits generated audible hiss and hum of their own. But NAD’s no-compromise electronics are quieter than any tape (including new tape formulations presently being developed), guaranteeing that the recorder will never limit the dynamic range of your recordings.
