ケンウッド カタログ・昭和59年7月

A brochure for the KENWOOD KA-1100SD integrated amplifier, July 1984. The centerpiece is the Super DLD (Super Dynamic Linear Drive) circuit: KENWOOD split the power supply into two independent transformers - one for low-power operation, one for high-power - keeping bass-range noise from the heavy output stage out of the quieter signal path. That gets you 180+180W at 6 ohms, 20Hz-20kHz, damping factor 1000. Also on board: Sigma Drive type B (2-wire speaker control), CD Direct Switch, dual MM/MC phono stage, and 8 input/output systems for a full AV setup. The back page is a price list for the wider KENWOOD line - amplifiers KA-990, KA-880, KA-770 and tuners KT-2200, KT-1100, KT-770, KT-100, KT-101.

ひとつの命題をつくりあげ、その回答をカタチにしていく。アンプづくりは、推理小説の謎解き作業にも似ています。KA-1100SDの命題はデジタルソースにふさわしい量感をもち、しかも歯切れのいい低音域の再現。この新しい低音再生へのケンウッドの回答がSuperDLDサーキットです。複数の電源回路をフルに活用し、電力のすべてをスピーカーをドライブするパワーとして燃焼。これまで、アナログレコードの柔らかさに吸収されていた低音の粒立ち、レコード針が追従できなかった大信号と小信号の音の落差など、デジタルソース独特な低音域を見事に描きあげます。さらに2線式のスピーカーコードで使いやすさを追求したΣドライブtypeB、さらにCD、TAPE・Cポジションを新設してAV時代に備えた8系統の入出力端子群など、数かずのニューテクノロジーが、デジタル時代のアンプの謎を解いた。音の21世紀はもう始まっている。Setting one proposition and giving its answer a concrete form: building an amplifier is much like solving the mystery in a detective novel. The proposition of the KA-1100SD is the reproduction of a bass range with a sense of volume worthy of digital sources, and with crisp articulation at the same time. Kenwood's answer to this new kind of bass reproduction is the Super DLD circuit. Making full use of multiple power supply circuits, it burns all of the electric power as power to drive the speakers. It brilliantly portrays the bass range unique to digital sources: the definition of bass notes that used to be absorbed by the softness of analog records, and the difference in sound between large and small signals that the record stylus could not follow. Numerous new technologies, such as the Σ drive type B, which pursues ease of use with a 2-wire speaker cord, the newly added CD and TAPE・C positions, and the group of 8-system input/output terminals prepared for the AV era, have solved the mystery of the amplifier for the digital age. The 21st century of sound has already begun.
