Denon SC-1200 (1984) - Studio Monitor

 

Brand: Denon

Model: SC-1200

Year: 1984

High quality, high-performance loudspeaker. Not what you'd first think of if, you mention the name Denon. The SC-2000 presented here was made by Denon in 1984 using a loudspeaker manufactured by "Gauss America". Gauss was an American (U.S.A.) speaker manufacturer founded by former retired JBL employee (Bert Loncansey, Ed May). This is however not the first Denon "Studio Monitor" nor the first cooperation between Gauss and a Japanese manufacturer (more baout this later). Anyway, the model presented here is using a Gauss 3588 coaxial 2-way unit. The woofer section is using a specially treated paper cone with multi-corrugations and a diameter of 38cm. The high frequency unit is a horn-shaped unit with a unique curved horn designed by computer design...with a a 50mm diaphragm. This coaxial unit provided excellent localization , and it also had the characteristics of a monitor speaker.

TEAC Sound Core (1989)

 

Relax and enjoy music. This is what the Sound Core Hi-Fi system is all about. Introduced by TEAC in 1989 the Sound Core system comprised three models the a-1, a-2 and a-3. The SOUND CORE series is a new form of audio system that was recommended to "modern people who are interested in both quality and design". The original promotional brochure also said that this is a: "Stylish European design that blends elegantly into your interior". The amplifier section of the a-1 model was 50W/ch, the a-2 was 30W/ch while the a-1 was 20W/ch. Only the a-1 and a-2 models featured auto-reverse cassette recorders but all models featured a CD player. The TZ-1 "AV furniture" was available separately, while the system had a wide range of loudspeakers available. First there was the TEAC Sound Core S-5 "designer model" and the S-100 but there was also a Tannoy Eclipse and a Mordaunt Short MS-35G available as additional units. The Sound Core systems had their dedicated remote controllers too, the RC-11 for the a-1 and a-2 models and the RC-33 for the a-3 model.    

KENWOOD KA-3300D (1987)

Brand: KENWOOD

Model: KA-3300D

Year: 1987

The KA-3300D Digital Integrated Amplifier was introduced by Kenwood in 1987. As response to the growing popularity of CD, the KA-3300D features a built-in D/A converter that will accept Digital signal from a CD player via a optical or coaxial cable. The D/A converter section consists of a 4x oversampling digital filter, left and right independent ladder network type D/A converters, and a 7th-order Butterworth FDNR type discrete low-pass filter. Additionally, in order to support digital sources that use different sampling frequencies, it has a built-in PLL data demodulator that automatically switches the clock (synchronization) frequency between 32kHz, 44.1kHz, and 48kHz. The amplifier section uses a Dynamic Linear Drive (DLD) circuit. This circuit employs two amplifiers, a low-power amplifier and a high-power amplifier. This allows a far better control of loudspeaker load fluctuations. The amplifier also features a New VIG (Voltage Interface Gate) circuit that interfaces the amplifier section and the power supply section. In addition, by keeping the voltage between the base and emitter of the power transistor constant, the VIG circuit suppresses the phenomenon in which fluctuation components generated by the power stage of the amplifier affect the pre-driver stage and driver stage. This allows for smoother signal transfer between the driver stage and the driver stage, enabling purer signal amplification.
