National NV-DS1 (1988) | Digital & Hi-Fi

 

The National (Panasonic) NV-DS1 introduced in 1988 features Multi-Digital play that allows "a flexible and creative visual expression" of your video material. The enjoyment of AV deepens even further when you recreate various video scenes exactly as you want. 8-bit digital processing allows for 9-screen playback, strobe effects, graphic art, mosaics, and digital combinations of these. You can enjoy a variety of special effects, including mixing. The LCD multi-digital controller allows for centralized operation. Based on the high image quality of the S-VHS system, it delivers finely detailed digital images. The "8WD system" which creates the image, reproduces multi-digital play and Fine Slow motion more beautifully. Hi-Fi sound. The richness of the sound is further enhanced. Digital sub-bass sound offers a large scale sense of presence. Even double bass is reproduced with powerful bass. The basic sound is Hi-Fi with a dynamic range of 90dB or more. Audio-grade aluminum electrolytic capacitors improve the sound's attack and the clarity of the mid and high frequencies. Sub-bass reproduction has two selectable positions (music) depending on the source. Other features include: Title creation - digital. Barcode title input. Built-in title editing function. Create original titles with the same easy operation as barcode.

Accuphase P-500 (1985) | Built for Perfect Pitch

Built for Perfect Pitch. There are limits in high-end audio that only the finest components can reach — and only true audiophiles can fully appreciate. The name Accuphase has long been synonymous with uncompromising sound quality, precision engineering, and timeless craftsmanship. Developed by a dedicated team of experienced audio engineers, every Accuphase amplifier is designed and built to achieve a level of performance that pushes the boundaries of modern audio technology. Rather than following short-lived market trends, Accuphase focuses on one goal: absolute sound reproduction combined with elegant, timeless design. The P-500 from 1985 was a Stereo Power Amplifier Engineered for the New Era of High-End Audio. This Accuphase stereo power amplifier combines legendary Accuphase engineering with advanced circuit design to deliver exceptional power, ultra-low distortion, and remarkable stability under all listening conditions. The output stage features six parallel push-pull power transistors per channel, utilizing high-power 150W collector-loss devices for a total of 12 output transistors per channel. With a theoretical maximum output capability of 4,200 watts, the amplifier maintains substantial operating headroom, ensuring outstanding reliability, effortless dynamics, and superior speaker control even at high output levels. To minimize switching distortion at low listening levels, the operating points are precisely controlled so that both the PNP and NPN output devices remain continuously active without signal cutoff. This advanced configuration delivers smooth, natural sound reproduction with exceptional clarity and transparency across the entire frequency range. The driver stage employs high-grade MOS-FET devices operating in a non-switching Class A equivalent configuration with a cascode push-pull topology. The preceding signal stage also utilizes a pure Class A cascode push-pull design, contributing to excellent linearity, low noise, and stable performance from delicate low-level passages to full-rated output power. A direct-coupled input configuration preserves signal purity and musical detail. To protect loudspeakers from potential damage caused by DC drift from connected preamplifiers, Accuphase’s proprietary DC servo system automatically eliminates unwanted DC components while stabilizing the amplifier against temperature-related drift. For maximum system flexibility, the amplifier provides both a standard 20kΩ input and a fully balanced 40kΩ balanced input connection for enhanced noise rejection and improved signal integrity. A built-in subsonic filter eliminates frequencies below 10Hz using carefully selected high-quality components that preserve overall sound quality without affecting the audible frequency range. The amplifier is also equipped with a precision analog power meter capable of directly displaying both dB levels and output wattage. Logarithmic compression enables accurate monitoring across a wide power range from -60dB to +3dB. A dedicated switch allows the meter illumination and display to be turned off when desired. For even greater versatility, the amplifier can also operate in bridged mono mode, transforming it into a high-performance monaural power amplifier capable of driving demanding speaker systems with exceptional authority and control. Specifications: Continuous average power 250W/ch RMS 8ohm | Dimensions (W/H/D) 480x218x445mm | Weight 33,5kg

Nakamichi CR-30 (1988) | Discrete Head

 

The Nakamichi CR-30 was created at the pinnacle of analog tape engineering of the brand. Combining legendary Nakamichi innovation with meticulous hand-tuned precision for exceptional sound reproduction. At the heart of the deck is Nakamichi’s renowned discrete 3-head system, featuring completely independent recording, playback, and erase heads. Unlike conventional combination head designs, this architecture eliminates high-frequency degradation caused by azimuth misalignment during recording, ensuring superior accuracy, clarity, and detail retrieval. The precision-engineered heads are constructed from durable Crystalloy material and utilize a proprietary head contour design that maintains an optimally polished surface throughout extended use. This advanced construction minimizes uneven wear and preserves near-new performance for over 10,000 hours of operation according to Nakamichi testing standards. For outstanding tape stability and reduced modulation noise, the transport mechanism uses a closed-loop dual-capstan system. By carefully controlling the rotational speed differential between the capstans, the system maintains ideal tape tension and consistent head contact without relying on pressure pads or tape guides. The sophisticated multi-regulated power supply isolates individual circuits to eliminate electrical interference and maximize performance consistency. High-speed discrete voltage regulators deliver exceptional response speed and stability through a design philosophy comparable to high-end separate audio components. Additional refinements include a silent transport mechanism, reference-grade DC amplifier circuitry, and a dual-mono amplifier configuration for superior channel separation and imaging accuracy. Acoustic isolation insulators further reduce the effects of external vibration, preserving low-level detail and sonic purity. The deck incorporates advanced Dolby B and Dolby C noise reduction systems for cleaner recordings with reduced tape hiss. Independent equalizer switching provides optimized playback compatibility across multiple tape formulations, while a tape slack prevention system enhances transport reliability. Convenience and connectivity features include adjustable output level control, headphone output, system remote terminals, and premium gold-plated input/output connectors for improved signal integrity. Each Nakamichi CR Series deck undergoes an extraordinary level of factory calibration and quality control. Approximately 30 internal adjustment points are meticulously optimized during production to minimize unit-to-unit variation and achieve reference-level performance. Unlike conventional cassette decks that offer limited bias calibration, the CR Series features six precision bias adjustment potentiometers for accurate optimization across all tape types and operating positions. To ensure uncompromising quality, every fully calibrated unit is subjected to 56 separate performance measurements before shipment. Only decks that meet Nakamichi’s exacting specifications are approved for release, delivering the exceptional analog fidelity and reliability that define the Nakamichi legacy. Specifications: 3-head system | 2+1 DC motor | Wow and Flutter 0,035% RMS | Frequency response 20-20.000Hz Metal tape -20db | Dimensions (W/H/D) 430x100x265mm | Weight 5,8kg | Various Market versions are: CR-3, CR-3A, CR-3E, CR-30
