UHER HiFi Z100 (1978) | Stadium Full of Sound

 

The UHER HiFi Z100 from 1978 allowed you to assemble a stereo system into a visually and technically coordinated functional unit in a space-saving manner. The EG 750 Hi-Fi stereo tuner, VG 850 stereo integrated amplifier with a 2x60W Sinus DIN power rating, and the CG 350 stereo cassette recorder could be inserted into three compartments. Below the device compartments is another compartment where accessories or parts can be stored, such as the W 775 headphones. In the lowest part of the rack, behind a mirrored glass door, there is space for the upright storage of approximately 100 12-inch records. There are also three drawers there for storing 10 compact cassettes each. The black oak decor is coordinated with the equipment. The rack's edges are impact-protected by black, anodized aluminum profiles, giving it an elegant appearance. The finishing profile of the intermediate shelves is also made of black anodized aluminum and completely covers the gap between two pieces of equipment, so that their feet remain invisible.

TELEFUNKEN TRX-2000 (1978) | Weltspitzenklasse - Made in Germany

 

The Telefunken TRX 2000 stands as one of the most ambitious and technologically advanced receivers of the 1970s, combining powerful quadraphonic amplification, precision digital tuning, and sophisticated German engineering in a single flagship component. Designed to exceed contemporary Hi-Fi standards, the TRX 2000 offered crystal oscillator-controlled digital tuning across FM, MW, LW, and SW bands, ensuring exceptional frequency accuracy and ultra-low distortion reception. Its illuminated digital display not only provided exact frequency readout but also functioned as a 24-hour clock, a highly innovative feature for its era. Delivering an impressive 2 x 60 watts RMS in stereo mode or 4 x 50 watts RMS in quadraphonic operation (4 x 90 watt Musik power), the TRX 2000 was engineered for both power and flexibility. The receiver supported SQ, Discrete, and CD-4 quadraphonic playback systems, making it a versatile centerpiece for advanced multi-channel audio installations. Seven touch-sensitive FM station presets allowed instant access to favorite broadcasts, while Telefunken's intelligent AFC system automatically disengaged during tuning and reactivated after a precisely timed delay for optimum station locking. A distinctive feature of the TRX 2000 is its quartet of fast-response LED VU meters, providing accurate real-time monitoring of amplifier output levels. Additional tuning aids included a signal strength indicator and computer-controlled AFC circuitry, helping users achieve the highest possible reception quality even with distant stations. Noise and rumble filters, presence control, and comprehensive tone adjustment options further enhanced listening enjoyment across all program sources. The receiver's remarkable connectivity reflected its professional ambitions. The TRX 2000 could accommodate up to six loudspeakers, two turntables, three tape recorders, three headphones, and a microphone simultaneously. Its innovative two-room, two-program capability even allowed different audio sources to be enjoyed independently in separate rooms. Built in a striking matte-black metal chassis, the Telefunken TRX 2000 earned widespread acclaim from the specialist hi-fi press, which praised its outstanding FM performance, powerful 4 x 50 watt amplifier section, and wealth of advanced features. Often described as Telefunken's entry into the highest echelon of high-fidelity audio, the TRX 2000 remains a highly sought-after vintage receiver, admired by collectors and enthusiasts for its unique blend of digital innovation, quadraphonic capability, and exceptional German craftsmanship. Dimensions (W/H/D) 494x163x386mm | Weight 23,5kg | Original sale price in Germany 3.100 DM

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
