Kenwood (ケンウッド, Ken'uddo) is a Japanese brand of consumer electronics. It has been owned by JVCKenwood since October 2011, when Kenwood Corporation merged with JVC. Kenwood manufactures audio equipment such as AM/FM stereo receivers, cassette tape decks/recorders, amateur radio (ham) equipment, radios, cellular phones, speakers, and ...
Accuphase. Accuphase Laboratory, Inc. (originally known as Kensonic Laboratory, Inc.) is a Japanese, Yokohama -based high-end audio equipment manufacturer founded by former Kenwood engineer Jiro Kasuga in late 1972. [1] Kasuga was not happy with the views of Kenwood relating to the follower of their High-End Supreme 1 unit (1967).
An integrated amplifier (pre/main amp) is an electronic device containing an audio preamplifier and power amplifier in one unit, as opposed to separating the two. [1][2] Most modern audio amplifiers are integrated and have several inputs for devices such as CD players, DVD players, and auxiliary sources. Vintage integrated amplifiers commonly ...
The first planar monolithic integrated circuit (IC) chip was demonstrated in 1960. The idea of integrating electronic circuits into a single device was born when the German physicist and engineer Werner Jacobi developed and patented the first known integrated transistor amplifier in 1949 and the British radio engineer Geoffrey Dummer proposed to integrate a variety of standard electronic ...
Damping factor. In an audio system, the damping factor is defined as the ratio of the rated impedance of the loudspeaker (usually assumed to be 8 Ω) to the source impedance of the power amplifier. [1][2][3][4][5][6] It was originally proposed in 1941. [7] Only the magnitude of the loudspeaker impedance is used, and the power amplifier output ...
Op amp integrator. The operational amplifier integrator is an electronic integration circuit. Based on the operational amplifier (op-amp), it performs the mathematical operation of integration with respect to time; that is, its output voltage is proportional to the input voltage integrated over time.
