How can such performance be achieved at the 6155’s modest cost? NAD concentrates its engineering budget entirely on those aspects of design and manufacturing that affect the audible performance of the recorder, while omitting cosmetic frills and features that have little or nothing to do with how well the machine reproduces the true sound of music. The NAD 6155’s superior performance is derived mainly from three design elements. One is an NAD “first,” and the other two are found in only a few ot

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 bo

Play Trim and HX Pro circuits give the 602 the advantage of being able to reproduce accurately a wide range of pre-recorded tapes even home recordings, with noise free brilliance. The 602 automatically senses tape type and switches its internal electronics for optimum reproduction and ease of use. Two quiet DC motors, coupled to a belt driven balanced flywheel ensure flutter free capstan operation. Speed accuracy ±1% Wow and flutter <0.06% JIS weighted, RMS <0.1% DIN weighted, peak Freq

An overload indicator informs you when the saturation level of a tape is reached when making a recording.

The NAD Model 613 may be the only cassette deck in its price range to faithfully reproduce a wide-range CD without dulling its impact. Features and Circuitry Rather than incorporating features such as Search facilities, etc. which can degrade the overall sound quality and reliability, the NAD Model 613 offers features which are specifically tailored towards the most common uses for a cassette deck; making high quality recordings and play-back of pre-recorded tapes. With almost any other deck

The NAD Model 616 dubbing deck is an exception to this rule; convenience combined with the performance one would expect from a high quality, single well deck. Features and Design Rather than incorporating seldom used features such as Auto Search, etc. which can degrade the overall sound quality and reliability, the NAD Model 616 offers features which are specifically tailored towards the most common uses for a dubbing cassette deck; making high quality recordings and copies, uninterrupted play
