McIntosh MC-2300
The McIntosh MC-2300 is a solid-state power amplifier which was built by the American high-end audio company McIntosh, and sold between the years 1971 and 1980. In terms of McIntosh "family lineage" or production order, the MC-2300 was immediately preceded by the MC-2105 (with blue meters) and the MC-2100 (without), which were both 100 watt-per-channel stereo amps (200 watts monophonic) sold between 1969 and 1977. Before these came the MC-2505 (blue meters) made between 1967 and 1977, and the meterless but popular MC-250 sold from 1967 to 1979, both of which were 50 WPC stereo amplifiers (100 watts mono.) The MC-2300 was succeeded by the even more powerful MC-2500 (500 WPC stereo/1000 watts mono), sold from 1980 to 1990; and then the MC-2600 (600 WPC stereo/1200 watts mono), which was available between the years 1990–1995. Design Physically, the MC-2300 is a very large and sturdy amplifier, measuring 10.5 in (26.7 cm) high x 19 in (48.3 cm) wide x 17 in (43.2 cm) de ...

Solid-state (electronics)
Solid-state electronics means semiconductor electronics: electronic equipment using semiconductor devices such as transistors, diodes and integrated circuits (ICs). The term is also used as an adjective for devices in which semiconductor electronics that have no moving parts replace devices with moving parts, such as the solid-state relay in which transistor switches are used in place of a moving-arm electromechanical relay, or the solid-state drive (SSD) a type of semiconductor memory used in computers to replace hard disk drives, which store data on a rotating disk. History The term "solid-state" became popular at the beginning of the semiconductor era in the 1960s to distinguish this new technology based on the transistor, in which the electronic action of devices occurred in a solid state, from previous electronic equipment that used vacuum tubes, in which the electronic action occurred in a gaseous state. A semiconductor device works by controlling an electric current co ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Audio Power Amplifier
An audio power amplifier (or power amp) is an electronic amplifier that amplifies low-power electronic audio signals, such as the signal from a radio receiver or an electric guitar pickup (music technology), pickup, to a level that is high enough for driving loudspeakers or headphones. Audio power amplifiers are found in all manner of sound systems including sound reinforcement system, sound reinforcement, public address system, public address and home audio systems and musical instrument amplifiers like guitar amplifiers. It is the final electronic stage in a typical audio playback signal chain, chain before the signal is sent to the loudspeakers. The preceding stages in such a chain are low power audio amplifiers which perform tasks like preamplifier, pre-amplification of the signal (this is particularly associated with record turntable signals, microphone signals and electric instrument signals from pickups, such as the electric guitar and electric bass), equalization (au ...
