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. HIGH HEADROOM FOR PEAKS The 6130 is equipped with a hard permalloy record/play head. Permalloy has long been recognised as an ideal material for recording heads, because it has lower distortion at high signal levels than most other head materials. With this head you can take advantage of the greater dynamic range of today’s high- performance tapes to capture dynamic musical peaks with maximum clarity and power. The ability of the permalloy head to handle high signal levels without saturating is especially important with high-bias (chrome) and metal-particle tape formulations. These tapes excel in high-frequency dynamic range, allowing you to capture the full brilliance and power of cymbals, bells, brass, and synthesisers in clear, airy sound. DOLBY B NR FOR COMPATIBILITY The NAD 6130 contains a correctly calibrated Dolby B-type noise-reduction circuit for optimum compatibility with prerecorded music cassettes throughout the world. Dolby B-type NR can also be used when recording tapes for friends or for playback in a portable or auto tape player. RELIABLE LOW-FLUTTER TAPE TRANSPORT In a budget-priced tape deck, one of the greatest challenges is to obtain-consistently low flutter from beginning to end of every tape, Even a modest amount of flutter, too slight to be separately audible as a wobbling of the musical pitch, can cause a loss of clarity-making a recorded tape seem unsteady and fatiguing to listen to. The tape transport in the NAD 6130 is an economical design whose apparent simplicity of construction belies its excellent reliability. It employs a quiet, smooth-running DC motor whose torque, as in a fine turntable, is transferred to the capstan spindle via a rubber belt and a balanced flywheel to smooth out any irregularities, reducing the flutter to well below the threshold of audibility. INSTANT-RELEASE PAUSE CONTROL Ideally, a Pause control should provide a precise interruption in recording or playback-but many Pause controls are anything but precise, with an audible delay in their response. In the 6130 the Pause control provides a virtually instantaneous resumption of recording or playback, providing clean edits and allowing you to make recordings that start exactly when you want them to.
