Aurex PC-X46AD (1981) | adres deck & unit

 

The Aurex PC-X46AD cassette deck from 1981 is a high-performance vintage tape deck featuring a then newly developed dual-motor transport mechanism and Aurex’s proprietary ADRES noise reduction system. Designed to dramatically reduce cassette tape hiss while expanding dynamic range, ADRES technology delivers cleaner highs, lower distortion, and improved overall sound quality without bleeding noise. The PC-X46AD also supports playback of ADRES-encoded recordings, with a convenient CAL adjustment system and level marker memory that allows precise calibration and easy recall of optimized recording levels. Built around a 2-motor IC logic transport, the PC-X46AD separates capstan drive and reel drive motors for improved torque stability and reduced wow and flutter. For superior audio performance, the deck is equipped with a Super AP (High-B Hard Permalloy) record/playback head featuring high magnetic flux density and wide saturation capability. Its hyperbolic contact surface ensures optimal tape-to-head contact, reducing distortion and level fluctuations. A dedicated 2-gap AF (Arex-ferrite) erase head provides efficient and clean erasure. Additional features include Dolby Noise Reduction, illuminated one-touch IC logic controls, pause/mute function, auto-repeat playback mode, timer standby capability for unattended recording and alarm playback (with optional external timer), backlit peak level meters ranging from -40 dB to +10 dB, adjustable output level control, and a DC-configured recording/reamp section optimized for high-fidelity sound reproduction. An integrated MPX filter activates in FM mode to improve recording quality from FM Stereo tuner sources. The PC-X46AD is also compatible with an optional remote control, making it a versatile and user-friendly addition to any vintage hi-fi system. On top of the PC-X46AD we can also see the AD-4MKII additional adres noise reduction unit. Specifications: 2-head, 2-motor mechanism | Wow & Flutter 0,035% (WRMS) | Frequency response 20-19.000 Hz Metal tape | Signal-to-Noise (adres on) 88dB | Dimensions (W/H/D) 420x110x280mm | Weight 4,2kg | Remote control RM-15S

Victor HR-20000 (1994)

 

Refined high-quality picture and sound. A magnificent prestige video deck that pursued the truest image and pushed the limits of Super VHS. What kind of Super VHS video deck should we have when pursuing the perfect image? Development of the HR-20000 began with a reexamination of all fundamentals. Numerous new innovations were incorporated into the head, amplifier, and digital signal processing circuitry, and the mechanism was designed to be simple and highly accurate, with improvements made to functionality and operability. The result was the HR-20000, which has solidified its reputation as the prestige model of Super VHS. SC pro head - JVC's high-performance head, which combines high output and low noise, has been further improved. The head width has been balanced to an optimal value. By eliminating crosstalk from adjacent tracks, recording characteristics have been improved, resulting in clearer image quality. Equipped with 629 Digital TBC - the key to stable images and low noise. This function corrects the time axis jitter of the scanning lines caused by tape movement and vibration. It significantly reduces the curvature and roughness of vertical lines, and also effectively corrects jitter-like hue fluctuations and high-frequency jitter, reproducing natural and stable images. Super Solid DD Mecha - Professional-grade high-precision mechanism, Super Solid DD mechanism. The two-reel direct drive and super impedance roller ensure stable tape running with virtually no tension fluctuation, reducing jitter. Furthermore, the full-loading, high-response design ensures high-speed, quiet FF and REW. 3D digital Y/C - A 3D digital Y/C separation circuit that delivers high-quality images on wide screens. The DP-1000 is equipped with a motion-adaptive Y/C separation circuit that eliminates pixel interference and cross color without affecting resolution in any direction, including diagonal directions. This enables the reproduction of fine details and the expression of a clear three-dimensional effect, delivering the high-quality images required in the widescreen era. 3D Hadamard NR - Beautiful details even when played back on a large screen. Digital Hadamard processing using frame memory significantly reduces minute noise added to the luminance signal during recording and playback. AI homme calibration - AI auto-calibration produces high-quality images that are not affected by the tape. The optimum recording level, which varies slightly depending on the tape being recorded, is detected and automatically set. This maximizes the capabilities of each individual tape, achieving high-quality recording and playback. Furthermore, the introduction of a new algorithm has sped up the calibration process to less than 10 seconds. It is also possible to correct changes in characteristics due to head aging. FET amplifier - A hyper-parallel FET preamplifier is used to achieve low noise from the ground up. The amplifier section, which has often been overlooked in the past, has been given a thorough upgrade in quality, with FET preamplifiers that amplify the same signal in parallel for each playback head. The 18 FET preamplifiers, with standard and triple amplification, significantly reduce noise below a few MHz. A thorough vibration-damping structure design eliminates vibrations that affect the image. Vibration control is enhanced by using high-density materials on the bottom and both sides of the chassis, vibration-damping steel plate for the bottom plate, and insulators with a triple suspension structure. NF Super Rewind - NF Super Rewind rewinds a 120-minute tape in just under a minute. If there is a large amount of tape to be rewound, high-speed rewinding is performed in the unloaded state. Airtight door - Airtight cassette door for quieter operation. The cassette slot is fitted with a double-action airtight door that provides a tight seal, blocking out internal noise from the tape and other components, resulting in quieter operation.

JVC L-E22 (1983)

 

The JVC L-E22 was the smallest linear tracking turntable in the 1983 lineup. It was a compact (340x87x340 mm) fully automatic belt drive turntable featuring the MD-1045 T4P type cartridge mounted to a statically balanced linear arm. In order to play a record, you must close the top cover. All the functions can be controlled via the small pushbuttons placed on the front panel.
