A single amplifier can usually power a woofer and a tweeter only through a post-amplifier crossover filter, which protects each driver from signals outside its frequency range. Bi-amping of speakers requires double the channels of amplification and can be accomplished using two ordinary amplifiers in either a vertical or horizontal arrangement.
Look, practicing guitar can get pretty boring — especially if you’re still plucking away at your beginner guitar and basic practice amp. Unless you want to spend hundreds (or thousands) of ...
Guitar wiring refers to the electrical components, and interconnections thereof, inside an electric guitar (and, by extension, other electric instruments like the bass guitar or mandolin). It most commonly consists of pickups , potentiometers to adjust volume and tone, a switch to select between different pickups (if the instrument has more ...
The two common guitar amplifier configurations are a combination ("combo") amplifier that includes an amplifier and one or more speakers in a single cabinet, and a standalone amplifier (often called a head or amp head), which passes the amplified signal via a speaker cable to one or more external speaker cabinets. A wide range of speaker ...
The two channels of a stereo amplifier are fed the same monaural audio signal, with one channel's electrical polarity reversed. A loudspeaker is connected between the two amplifier outputs, bridging the output terminals. This doubles the available voltage swing at the load compared with the same amplifier used without bridging.
A guitar amplifier amplifies the electrical signal of an electric guitar so that it can drive a loudspeaker at sufficient volume for the performer and audience to hear. Most guitar amplifiers can also modify the instrument's sound with controls that emphasize or de-emphasize certain frequencies and add electronic effects.
A typical, simple application combines signals from microphones on stage into an amplifier that drives one set of loudspeakers for the audience. A DJ mixer may have only two channels, for mixing two record players. A coffeehouse's small stage might only have a six-channel mixer, enough for two singer-guitarists and a percussionist.
The Loog Mini has a built-in amp and speaker as well as a three-string design (instead of the usual six) to make learning easier. It also comes with chord flashcards as well as access to the ...
