SONY XK-700 (1984) | MegaCosmos

 

The XK-700 computer controlled feather touch deck fully incorporates Sony's advanced technologies, including a dual battery mirror system. A battery mirror system that uses a single car battery to create two power sources. This unique Battery Mirror system overcomes the limitations of car batteries—single polarity and low voltage. By creating symmetrical positive and negative dual power supplies from a single battery, it becomes possible to design circuits equivalent to those used in home audio systems, doubling the dynamic range. It also features a dual-adjust head mechanism that makes the playback frequency characteristics identical in both forward and reverse directions. The dual-adjust head mechanism adjusts the head tilt to the optimal state for both normal and reverse playback, maintaining accurate azimuth at all times. Nearly identical frequency characteristics are achieved for tape playback in both directions. A microcontroller controls multiple functions. Operation is as light as a feather touch with your fingertips. Power Loading System: Simply insert the cassette into the slot and press the play button, and it will automatically slide in and set in the correct position. To remove it, simply reverse the process for a soft and smooth ejection. Repeat function allows you to listen to the same song over and over again with a single touch. AMS allows you to quickly jump to the beginning of the current song or the next song. Muting (-20dB) is convenient for temporarily lowering the volume. Switching the tape direction is also done softly with a single touch. Key-off eject mechanism automatically ejects the cassette when the engine key is turned off. Built-in Dolby NR Type B to reduce tape hiss noise ● 2-position tape selector for Metal tape playback compatibility ● Large peak program meter for visually checking tape levels ● Unique bass/treble tone controls. Basically the XK-700 was part of Sony's modular reference system "MegaCosmos" designed for those seeking the best possible sound in car audio. It boasts exceptional sound quality and ease of use, and is also compatible with CDs. As part of this "700 system" the XM-700 power amplifier employs large-capacity flat-type electrolytic capacitors, achieving high power of 80W + 80W, a wide dynamic range, and a low distortion rate of 0.005%. The speakers are a 3-way system using square flat-panel APM speakers born from Sony's audio technology. The CDX-R7 was the "FM/AM Compact Disc Player" that completed this Hi-Fi car audio system. Frequency response: 30-20.000 Hz | Size 178x50x150 mm | Original sale price in japan 59.800 Yen

SONY SL-HF1000D (1986) | Super Hi-Band - Beta Hi-Fi

 

The HF1000D combines Super Hi-Band 6.0Mhz beta-Is with Beta Hi-Fi technology in order to achieve achieve a dynamic range of 90dB. This high-band Beta Hi-Fi system aims for pure visual and pure audio. When people encounter excellent visuals and excellent sound, their eyes, ears, and hearts are filled with excitement. The HF1000D is a model that returns to the fundamentals of video production — the creation of authentic AV—and thoroughly pursues the highest quality. It features "SHB 6.0 mega-highband beta-Is", which has brought a dramatic improvement in video image quality, and Beta Hi-Fi sound. Based on this high image and sound quality, it is equipped with a variety of functions, including digital picture. In addition, a unique linear skating loading mechanism has been adopted. The amount of information that can be recorded increases, image quality inevitably improves. Building on the success achieved with the 5.6 MHz Highband, the HF1000D further upgrades the highband concept. It features SHB6.0 MHz Highband Is, which shifts the video signal carrier up by 400 kHz in Is mode. This significantly improves image quality in Is mode, which already had ample recording bandwidth. It can now faithfully reproduce the fine details of the original image, such as the subtle shading of face tones (skin tones) and the movement of wind patterns etched in the sand. Furthermore, the adoption of a newly developed dynamic color circuit improves color reproduction, reducing color noise that is often noticeable in dark areas. Achieving a dynamic range of 90dB and a flat frequency response, Beta Hi-Fi brought the reference quality to video sound. Therefore, with the HF1000D, Sony thoroughly refined every detail, building upon the excellent fundamental technologies of Beta Hi-Fi, such as the 4-carrier system and zero-sampling method. The circuit section employs a symmetrically configured, highly integrated IC for Hi-Fi audio, significantly improving characteristic changes caused by subtle circuit differences. Furthermore, Sony incorporated carefully selected parts, including high-performance HAL filters and Ceramic capacitors with excellent vibration resistance and responsiveness. In addition, it was adopted a gold-plated input/output terminal and LC-OFC circuit wiring, resulting in an overall audio-spec design that achieves a dynamic range of 90dB. Moreover, it boasts an extremely flat frequency response from 20Hz to 20kHz, achieving acoustic characteristics that can be considered a reference for video sound.

Digital picture function allows you to enjoy special playback with clear images. Five different digital still image patterns have been implemented. These functions can be freely enjoyed using the HF1000D unit and the wireless remote control. The HF1000D employs a linear skating mechanism that enhances the audio experience. The HF1000D uses the same linear skating mechanism found in CD and video disc players. Pressing the eject button causes the cassette tray to automatically pop up, making tape loading and removal smoother.
