stereo amplifier

Formed in 1946, the Trio Corporation has gained an enviable reputation for its development and manufacture of high class equipment. For those sophisticated audiophiles who can appreciate the 0.0024% tuning accuracy of the 700T Frequency Synthesizing Tuner ... the exceptional control flexibility of the 700C Preamplifier-Control ... the masterful power of the 700M Main Amplifier with its incredible 170 watts per channel Min. RMS (at 8 ohms, 20 to 20,000 Hz with no more than 0.1% total harmonic distortion) ... Trio-Kenwood proudly presents the 700 Series. Each boasts technical specifications well beyond any previous efforts. Each incorporates the most advanced electronics, the most imaginative design concepts. Together they go beyond state-of-the-art performance and come closer to realizing total fidelity by producing a range of realistically priced high grade equipment that is among the best on the world market. During it's 6 years of manufacturing the 700 Series was sold under TRIO, TRIO Supreme and KENWOOD badges. Priced approximately 2150 USD (1975)

KENWOOD KX-1100G (1985) - Superb Recording and Playback Performance



cassette deck


With the introduction of the KENWOOD KX-880, a very successfull line of cassette decks was born. In 1985 as a further development of the 2 head KX-880, KENWOOD introduced the KX-1100G. This is a 3-Head Dual-Capstan cassette deck with Dolby B and C noise reduction circuits, built around a very good Direct Drive 3-motor mechanism sourced from Sankyo.  A so called Super Twin Loop Linear Exciter recording head amplifier was used together with a low-impedance large-core Amorphous Alloy recording head. The closed-loop dual capstan system features a so called Magnetic Thrust Absorber while the whole deck features a high-rigidity structure. Best recordings can be achieved with the use of bias and recording level calibration with oscillators and separate L/R controls. Recording levels are controlled by a Master and L/R preset level controls while the recording level is displayed on a vertical fluorescent peak-hold meter. In 1988 was introduced the KX-1100HX model with added Dolby HX-Pro circuit.

KENWOOD L-08M - Rebirth of the Amplifier...1980

KENWOOD L-08M

Here is a unique, back-to-the basics amplifier design that considers every aspect of performance between the preamplifier input to the speaker input terminals. For the dedicated audiophile seeking perfection in sound reproduction, the ideal hi-fi setup includes separating the preamplifier's small-signal circuitry from the large-current using circuits of the power amplifier. Yet, in spite of all the recent improvements in amplifier performance, the perceptive listener is often left with the nagging feeling that the sound is still not at all as "total" as it should be by the time it emanates from the speakers. Breaking away from conventional "tunnel vision" in amplifier design, KENWOOD engineera intensively investigated this credibility gap between specification promises and actual results, to reach an amplifier design concept that takes into account every single stage of signal handling, including the link between the separate units, the power supply system, and even dynamic effects of the speakers themselves. The L-08 Sigma Direct Drive Amplifier System thus actually achieves what must become the primary objective in amplifier design - a stunning mirror image of the purity of the original music signal all the way to speaker system.

The L-08M is a single-channel power amplifier that "directly drives" the speaker to which it is connected. The concept of Direct Drive is based on the accepted theory that the shorter the speaker connecting cord, the better the sound quality. In the original Kenwood Direct Drive amplifier system, an excellent amplifier-speaker relationship was obtained through locating each single-channel amplifier a meter away from its speaker. However, the New Hi-Speed amplifier with Sigma Drive functions as a direct-drive amplifier in the same way, even when the L-08M is located at some distance from the speaker. As Kenwood data shows, the L-08M provides outstanding performance relative to any other amplifier setup. For example, Damping Factor at the end of the 3-meter Sigma cords is still 15,000, while even at 10-meters it is over 20,000, which is more than 100 times better than most other amplifier DFs measured at the amplifier output terminals. Moreover, such is the innate superiority of the L-08M's circuitry that even without using the Sigma cords and substituting conventional speaker cords instead (the L-08M can still be used as a " n o r m a l" amplifier), the tonal quality has a clear edge over others, as a comparative listening test will prove.

The Story of ROXY - KENWOOD midi in Japan.

kenwood roxy

In the early 80's most major japanese manufacturers began to release midi sized Hi-Fi components that quickly became extremely popular in Japan. These systems had "family names" in Japan, not just model type designation. In the early days these were true separate components with matching design and appealing functions and displays. Among the polpular systems were the ROXY and ESPACE systems built by KENWOOD (between 1982 - 1993). Here are a couple of the finest examples of these wonderfull Hi-Fi components.

Vertical CD player (part 3 TOSHIBA)


Part 3 of our series dedicated to first generation vertical CD players from 1982-1984 continues with the TOSHIBA based models. Originally created by TOSHIBA as model XR-Z90 this player was also available in Japan as Aurex XR-Z90. As a leader in CD audio technology this unit was sold as rebadged units as well. These were the KENWOOD L-03DP, LUXMAN DX-104 and the Alpine AD-7100.

KENWOOD LX-1 LX-2 and LX-3

This is the functional prototype LX series made by TRIO-KENWOOD in 1979, only presented at audio fairs. The components are the LX-1 preamplifier, LX-2 poweramplifier and the LX-3 tuner. There were only 3 sets ever made. What was finally produced was the KENWOOD L-01A amplifier and the matching L-01T FM tuner.
