The black rubber pinch roller is at upper right. The 8-track tape (formally Stereo 8; commonly called eight-track cartridge, eight-track tape, and eight-track) is a magnetic-tape sound recording technology that was popular [2] from the mid-1960s to the early 1980s, when the compact cassette, which pre-dated the 8-track system, surpassed it in ...
An instrumentation amplifier (sometimes shorthanded as in-amp or InAmp) is a type of differential amplifier that has been outfitted with input buffer amplifiers, which eliminate the need for input impedance matching and thus make the amplifier particularly suitable for use in measurement and test equipment. Additional characteristics include ...
Audio stereo power amplifier made by McIntosh The internal view of a Mission Cyrus 1 Hi Fi integrated audio amplifier (1984) [1]. An audio power amplifier (or power amp) amplifies low-power electronic audio signals, such as the signal from a radio receiver or an electric guitar pickup, to a level that is high enough for driving loudspeakers or headphones.
An amplifier is defined as a circuit that has a power gain greater than one. [2][3][4] An amplifier can be either a separate piece of equipment or an electrical circuit contained within another device. Amplification is fundamental to modern electronics, and amplifiers are widely used in almost all electronic equipment.
A pentode is an electronic device having five electrodes. The term most commonly applies to a three-grid amplifying vacuum tube or thermionic valve that was invented by Gilles Holst and Bernhard D.H. Tellegen in 1926. [1] The pentode (called a triple-grid amplifier in some literature [2]) was developed from the screen-grid tube or shield-grid ...
A linear amplifier is an electronic circuit whose output is proportional to its input, but capable of delivering more power into a load. The term usually refers to a type of radio-frequency (RF) power amplifier, some of which have output power measured in kilowatts, and are used in amateur radio. Other types of linear amplifier are used in ...
Bass amplifier. An Ampeg SVT cabinet with eight 10" speakers, with a separate Ampeg SVT amplifier "head" on top. A Yamaha B100-115 combo amp, which contains a 100 watt amplifier and one 15" speaker in a wooden cabinet. A Hartke 500 watt amp "head" on top of an Ashdown 4x10" speaker cabinet. A bass amplifier (also abbreviated to bass amp) is a ...
The company was known for the most powerful audio amplifiers of the era led by the Phase Linear D-500 introduced in 1978. It was a stereo power amplifier delivering 505 watts of clean (typically < 0.1% total harmonic distortion over 20 Hz–20 kHz) RMS power per channel. It had a retail price of $1395. Buyout.
