Mackie’s CR4-XBT speakers are technically studio monitors—the kind that musicians and audio professionals generally use to get the most accurate, balanced sound possible for recording purposes.
Computer speakers, or multimedia speakers, are speakers sold for use with computers, although usually capable of other audio uses, e.g. for an MP3 player. Most such speakers have an internal amplifier and consequently require a power source, which may be by a mains power supply often via an AC adapter , batteries, or a USB port.
A PC speaker is a loudspeaker built into some IBM PC compatible computers. The first IBM Personal Computer , model 5150 , employed a standard 2.25 inch magnetic driven (dynamic) speaker. [ 1 ] More recent computers use a tiny moving-iron or piezo speaker instead. [ 2 ]
A headphone amplifier is a low-powered audio amplifier designed particularly to drive headphones worn on or in the ears, instead of loudspeakers in speaker enclosures. Most commonly, headphone amplifiers are found embedded in electronic devices that have a headphone jack, such as integrated amplifiers , portable music players (e.g., iPods), and ...
Dumble was a guitar amplifier manufacturer in Los Angeles, California. A Dumble Overdrive Special . In the one-person operation, Alexander "Howard" Dumble (June 1, 1944 – January 16, 2022) [1] [2] made each amp personally. Because of this, Dumble amplifiers are the most expensive boutique amplifiers on the used market, [3] and
An amplifier, electronic amplifier or (informally) amp is an electronic device that can increase the magnitude of a signal (a time-varying voltage or current). It is a two-port electronic circuit that uses electric power from a power supply to increase the amplitude (magnitude of the voltage or current) of a signal applied to its input ...
Chromecast devices are dongles that are powered by connecting the device to an external power adapter or USB port using a USB cable. Video-capable Chromecasts plug into the HDMI port of a high-definition television or monitor , while the audio-only model outputs sound through its integrated 3.5 millimeter audio jack / mini-TOSLINK socket.
For transistors, the current-gain–bandwidth product is known as the f T or transition frequency. [4] [5] It is calculated from the low-frequency (a few kilohertz) current gain under specified test conditions, and the cutoff frequency at which the current gain drops by 3 decibels (70% amplitude); the product of these two values can be thought of as the frequency at which the current gain ...
