Commentary
An adres-compatible cassette deck that uses a D. D. motor.
As a noise reduction system, it is equipped with an adres unique to Aurex.
As for adres, the hissing, which was a major drawback of the cassette, has been greatly reduced, while at the same time the dynamic range has been expanded to achieve higher sound quality, while avoiding bleeding noise and distortion.
The capstan drive motor employs a flat-faced FG servo slot and coreless DC motor that rotates while the rotor is appropriately attracted to the stator coil side. This motor is equipped with a 3-phase 6-coil drive system and a 160 pulse all-around integration type high-brightness FG servo circuit. This greatly reduces the effects on the accuracy of the rotating system, such as torque ripple (cocking) and wow / flutter.
The mechanism uses a 2-motor IC logic, simple & silent mechanism.
This mechanism is simplified by adopting a 2-motor system in which the reel base is driven by a dedicated DC motor, and high performance is achieved by adopting a high-precision finished capstan shaft with roundness of 0.1 μ or less.
It uses an AS (all-sendust) head for recording and re-recording that has excellent magnetic characteristics and abrasion resistance.
By adopting a hyperbolic shape for this head, contour is reduced and a flat characteristic with no sense of strain is obtained.
The recorder / re-amplifier section has a DC configuration without a condenser from each circuit, and the layout of wiring, elements and boards has been simplified to eliminate hum and noise.
Equipped with a backlighting type peak meter.
Equipped with a timer standby mechanism.
Equipped with a memory play function.
Equipped with Dolby NR.
It has an output volume.
Compatible with optional remote control.
