Class-B or-AB push – pull circuits are the most common design type found in audio power amplifiers.

The widespread adoption of digital music formats, such as CD or satellite radio, has displaced phonograph records and resulted in phono inputs being omitted in most modern amplifiers.

In most amplifiers, further power is consumed due to the quiescent current between the cathode and the anode ( plate ), resulting in heating of the plate.

Meters with electronic amplifiers ( all digital multimeters and some analog meters ) have a fixed input impedance that is high enough not to disturb most circuits.

For example, " a gain of five " may imply that either the voltage, current or the power is increased by a factor of five, although most often this will mean a voltage gain of five for audio and general purpose amplifiers, especially operational amplifiers, but a power gain for radio frequency amplifiers.

For most bands and most small-to mid-size venues ( e. g., nightclubs and bars ), standard bass guitar speaker enclosures or keyboard amplifiers will provide sufficient sound pressure levels for onstage monitoring. Since a regular electric bass has a low " E " ( 41 Hz ) as its lowest note, most standard bass guitar cabinets are only designed with a range that goes down to about 40 Hz.

There are also disadvantages: some amplifiers can oscillate when driving capacitive loads like most piezoelectrics, which results in distortion or damage to the amplifier.

Ribbons have a very low resistance that most amplifiers cannot drive directly.

However, the choices for the IF are most dependent on the available components such as mixer, filters, amplifiers and others that can operate at lower frequency.

However, TIM distortion is still present in most low price home quality amplifiers.

Over the years, Pete Townshend has used many types of amplifiers, including Vox, Fender, Marshall, Hiwatt etc., sticking to using Hiwatt amps for most of four decades.

While Bolan was known to use makes as diverse as Vox, Orange, HH Electronics and Marshall, he is perhaps most associated with the short-lived Vampower line of British amplifiers.

In most actual car systems, the amplifiers are connected in a bridge-tied load configuration, and speaker impedances are no higher than 4 Ω. High-power car amplifiers use a DC-to-DC converter to generate a higher supply voltage.

" Based on its most recent analysis, the Company now believes that, if the degradation of the S-band antenna amplifiers continues at the current rate or further accelerates, and if the Company is unsuccessful in developing additional technical solutions, the quality of two-way communications services will decline, and by some time in 2008 substantially all of the Company ’ s currently in-orbit satellites will cease to be able to support two-way communications services.

The guitars, bass guitars, and amplifiers he designed from the 1940s on are still relevant: the Fender Telecaster ( 1950 ) was the first mass-produced electric guitar ; the Fender Stratocaster ( 1954 ) is among the world's most iconic electric guitars ; the Fender Precision Bass ( 1951 ) set the standard for electric bass guitars ; and the Fender Bassman amplifier, popular enough in its own right, became the basis for later amplifiers ( notably by Marshall and Mesa Boogie ) that dominated rock and roll music.

Unlike most popular music amplifiers and equipment, Leslie Speakers use an amphenol connector to interface directly to an organ.

For 3 V input, it might then output 30 V. However, the model implies that at 50 V input it would produce 500 V, which is not possible with most amplifiers.

: Output power for amplifiers is ideally measured and quoted as maximum Root Mean Square ( RMS ) power output per channel, at a specified distortion level at a particular load, which, by convention and government regulation, is considered the most meaningful measure of power available on music signals, though real, non-clipping music has a high peak-to-average ratio, and usually averages well below the maximum possible.
