Mullard Circuits for Audio Amplifiers is a famous book by the Technical Services Department of Mullard Ltd, a British valve manufacturing company. First published in 1959 and then reprinted several times it contained a number of designs by Mullard engineers for high quality audio amplifiers, which were to be used by amateur constructors as well as by manufacturers as the basis for many ...
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.
Just like the Dallas Rangemaster, the Hornby Skewes treble booster was an amp-top unit. While early Hornby Skewes Treble Booster units used a germanium transistor, the later, better-known version features a silicon transistor. Rumours about a JFET version may source from a misread part number. [5] It's prominently featured on Jethro Tull's ...
The human ear perceives a 5-watt amplifier as half as loud as a 50-watt amplifier (a tenfold increase in power), and a half-watt amplifier is a quarter as loud as a 50-watt amp. Doubling the output power of an amplifier results in a just noticeable increase in volume, so a 100-watt amplifier is only just noticeably louder than a 50-watt amplifier.
In electronics, an antenna amplifier (also: aerial amplifier or booster) is a device that amplifies an antenna signal, usually into an output with the same impedance as the input impedance. Typically 75 ohm for coaxial cable and 300 ohm for twin-lead cable. An antenna amplifier boosts a radio signal considerably for devices that receive radio ...
It is known that it is the 'brilliant' model (or top boost) and it was Edge's earliest amp used to record every U2 album Since the higher output AC30/4 shared its preamplifier design with the lower powered AC15, Vox discovered the high-gain EF86 tube was susceptible to microphonics, or even failure, when exposed to the increased vibration ...
The Doherty amplifier is a modified class B radio frequency amplifier invented by William H. Doherty of Bell Telephone Laboratories Inc in 1936. Whereas conventional class B amplifiers can clip on high input-signal levels, the Doherty power amplifier can accommodate signals with high peak-to-average power ratios by using two amplifier circuits within the one overall amplifier to accommodate ...
Digital audio players such as Cowon's D2 and iAudio X5 ship with Ogg Vorbis support. Samsung YP series of digital audio players [58] ships with Ogg Vorbis support. The majority of iriver devices provide Ogg Vorbis support up to Q10 bitrates. [59] [60] [61] (as July 2008) Cowon C2 (Ogg and FLAC support)
