Description

Both the recording and playback heads in Denon's combination head system are made of a high flux density material that is ideal far magnetic components. The coil wiring employs a special copper material called PC-OCC (Pure Copper by Ohno Continuous Casting), which assures outstanding response characteristics up to very high frequencies. MOL (Maximum Output Level) is also notably improved, resulting in transparent clarity and highly precise stereo imaging.

The lifetime of an amorphous head is five times longer than that of a conventional Permalloy head.
Another important advantage of the amorphous head is that it improves high frequency dynamic range by as much as 2 to 2.5 dB at 14 kHz.

The Record/Playback and Erase heads are mounted in aluminium diecast bases. This design absorbs slight vibrations and effectively reduces modulation noise.

The distance between the recording head gap and the playback head gap was reduced from 4.8 to 4.3 mm, and the head received a new shape optimized with the help of computer analysis. The result is notably improved tape to head contact and minimal dropouts in the upper frequency range. The position of the tape guides was moved From the REC side to the PLAY side, for even more stable tape travel.

Dolby S uses the some technology as Dolby SR, a noise reduction system for professional applications. It allows absolutely faithful musk recording and playback by virtually eliminating any perceptible noise. The noise reduction effect is as high as 24 dB in the upper frequency region and a comfortable 10 dB in the low range. This results in wide dynamic range over the entire music spectrum.

The DNA-790R's elegantly simple CAM motor system is not only much quieter than conventional plunger or lever driven systems but also far more reliable. A special computer and encoder control circuit check the timing of tape and mechanism engagement to ensure optimum tape transport at all times. The computer also controls the display circuit, synchronizes the audio circuit with the timing of the tape transport mechanism, and activates the control buttons.

Perfectly constant tape tension is a prerequisite for stable tape to head contact. Denon's Dual Capstan Drive system thus provides a closed loop effect which isolates the portion of the tape that is centred on the head. Both the flywheel and capstan have been finished to micron accuracy to deliver the possible performance in every respect. The audible result is a superior sound with significantly reduced modulation noise.
