DD (Direct Drive) Mechanism Equipped with Newly Developed Quartz-locked Pulse Servo DD Motor
A direct drive system is employed in which the motor shaft itself is the capstan shaft, without the rotation transmitting members ( idlers, pulleys, etc.) which cause unstable tape rotation . Our newly developed pulse servo motor is employed fot the driving power source . The motor,s construction is free from thrust unbalance or cogging, thus permitting a high flywheel effect . For precise rotation , this motor uses a full-circumference integration type FG detection sysytem and an autobalance circuit which reduces torque unbalance , Thus the motor drives the tape transport mechanism with smooyh rotation. Further, the employment of the quartz lock system results inexceedingly small flucuation of speed.
Three-head System with X-cut SA Record-Playback Combination Head.
B.E.S.T. ( bias. equalizer. sensitivity tuning) System 3-head tape deck.
This system was developed for 3-head tape deck utilizing the concept of previous versions KD-A8, KD-A66.
To control the medium-frequency responce , a process o make the 4 KHz.1kHZ responce flat is provided .This responce is set at the average between those R and L values which are taken each at 8 steps. The tape sensitivity is set at an average of those R and L values which are taken 16 steps each. The higj frequency equalization level is adjusted at 16 steps each for R and L channels , independently.

DSC-Digital ,for High-quality Sound Reproduction DDSC-dynamic Discrete Surround Circuit, digital is a configuration specially designed by Denon in which all elements of the processor are optimized through ther use of selected high-perfomance discrete components , including separate AD and DA converters, with sophisticated DSP- surround decoding.
UHC - ULTRA HIGH CURRENT SINGLE PUSH-PULL CIRCUIT . for the past ten years , the dream of power amps of power has been to support low-impedance speackers. unfortunately however , the fulfilment of this dream has always been a difficult proposition , and Denon eventually felt the need to rethink its approach . the result has been to combine high output power with detailed musical expression , a high-grade solution that is the first of its kind. The challenge facing Denon has been to amplify with dynamic strength and absolute clarity the creativ a energy transmitted by the artist and tp keep apace with the ever-changing musical signal levels. a hefty power supply unit with ample reserves and a power amp that is capable of supplying pure, dynamic signals to the speakers so that the music is heard with absolute transparancy are the primary requiments . also required are transient responce characteristics that amplify even low-levels signals with impeccable precision. no matter how superior the dynamic range or the frequency characteristics may be , these features are meaningless if the amp cannot instantly follow the sudden rises and falls in sound.
ALPHA Processor. Alpha processing is the worlds first technical formula for reproducing an analog waveform from the reproduction of 16-bit data in 20-bit quality. the alpha processor interpolates the digital data recorded on a cd and reproduces it in waveform that is very close to the way these musical signals would look in a natural analog wavewform.
DIGITAL BASS MANAGEMENT , When playing multi chanel Dolby Digital, LPCM, or DVD-Audio, MLP ,source, it possible to preset speaker configurations and delay times. The crossover point is fixed at 80 hz with 12 db high and 24 db low pass filter slopes. |

Техническое объяснение терминологии 1996- 1998 фирмы TECHNICS
AZ HEAD-В 1996 Техникс. Он произвёл инновационный прорыв в сфере аудио-головок для кассетных дек. Головка воспроизведения была разработана по новой технологии. AZ - противомагнитное покрытие (магнитно-резистивный композит ) которым тончайшим слоем покрыта головка. Благодаря данной технологии снижается уровень помех. Позволяет свести на минимум контакт с кассетной плёнкой, что также сказывается на воспроизведении кассет с более частотной характеристикой. улучшается отдача на высших частотах рабочего диапазона. Также AZ повышается ресурс самой аудио-головки и нет необходимости производить размагничивание головки, а благодаря тонкой плёнке отсутствует эффект магнетизма.
PLAY DIRECT - данная функция установлена на кассетной деке TECHNICS-AZ 7 с системой AZ головок. Это система позволяет получать более чистый звук или "живой звук", минуя фильтры и декодеры долби.
ATC - система калибровки фирмы Техникс. Позволяет произвести максимальную подстройку записи кассеты, регулировка эквалайзера, уровня частот и регулировка высоких частот. |

ALCA-auto level control with tape Analysis ALCA- analyses source signals and tape capability, then adjusts the recording level and bias settings, for high-quality recordings at the push of a single button.
FINE-TUNED AZIMUTH HEAD , Deck a Pioneer wide-range technology , reduces azimuth error to near zero by individually fine-calibrated head gaps.
FLEX-frequncy level expander , deck Any recorder tape sounds brilliant and rich in highs with the lack of highs automatically compensated for.
Reference Master Mechanism, deck A precision tape drive mechanism for accurate tape control combining a number of time-proven mechanical designs.
Tilting the mechanism 10 degrees from the vertical lessens the loads on tape, improving tape running stabiility.
S.R.T. smooth running tapeguide , deck Stabilises the running tape in contact with the recording , playback head for enhanced sound presence and localisation.
Super Auto BLE XD, Super Auto BLE, Auto BLE, Deck Optimises, bias , level and equalisation tape by tape for best result. Uses three SUPER AUTO BLE, or two AUTO BLE, calibration frequencies. Super Auto BLEA XD provides even more, wider dynamic range and better linearity at higher levels.
Wide-Range Technology, Pioneer technology to achieve wider dynamic range , wider requency and higher channel separation.
