In digital and analog audio, headroom refers to the amount by which the signal-handling capabilities of an audio system can exceed a designated nominal level. [1] Headroom can be thought of as a safety zone allowing transient audio peaks to exceed the nominal level without damaging the system or the audio signal, e.g., via clipping. Standards ...
Electrically, a headphone amplifier can be thought of as an amplifier that presents a very high input impedance (ideally infinite) and presents a lower output impedance (ideally zero) and larger range of output voltages (ideally infinite). This allows headphones of a low sensitivity to be driven louder as a result of the extra voltage provided ...
Integrated amplifier NAD 3060, 1978 [1] The NAD 3020 integrated amplifier A/V-components, 2009 (at High End fair, Munich) NAD Electronics is a brand name of an electronics firm whose products include home hi-fi amplifiers and related components. NAD is an abbreviation for New Acoustic Dimension.
On June 10, 2014, Kevin Hayes was issued U.S. Patent 8,749,310 for "amplifier bias control". This patent covers the only known technique for observing the true underlying quiescent current (idle current) of an output tube (or transistor) under dynamic signal conditions, and then holding it to the stable target value with a precision of 99% or ...
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 ...
A few Dumble amps have a Dumbleator circuit built in, but most have "un-buffered" input jacks that tap directly out of the pre-amp and into the power amp. Dumble likely created this external loop because of the difficulty of fitting effects loop buffering into the amplifier chassis (and the limited use of effects loops for most players).
The company was founded as SWR Engineering, Inc. by its namesake, Steve W. Rabe. Rabe was known for his engineering work at Acoustic Control Corporation.After extensive research with top Los Angeles studio bassists, SWR released its first commercial product in 1984, the PB-200 hybrid tube/solid-state bass guitar amplifier.
Clapton asked Jim Marshall to produce a combo amplifier with tremolo, which would fit in the boot of his car, and one of the most famous Marshall amps was born, the "Bluesbreaker" amp. [7] This is the amplifier, in tandem with his 1960 Gibson Les Paul Standard (the "Beano"), that gave Clapton that famous tone on the John Mayall & the ...
