Equalization, or simply EQ, in sound recording and reproduction is the process of adjusting the volume of different frequency bands within an audio signal. The circuit or equipment used to achieve this is called an equalizer. [1] [2] Most hi-fi equipment uses relatively simple filters to make bass and treble adjustments. Graphic and parametric ...
Graphic equalizer use leading to speaker damage is common — large amounts of bass boost and treble boost can distort music and damage loudspeaker drivers. [9] Ideally, the equalizer can be set once to compensate for the combination of the response of the speakers and the car's acoustic characteristics. [10]
Tone control is a type of equalization used to make specific pitches or frequencies in an audio signal softer or louder. It allows a listener to adjust the tone of the sound produced by an audio system to their liking, for example to compensate for inadequate bass response of loudspeakers or earphones, tonal qualities of the room, or hearing impairment.
Equalizer: An equalizer is a set of linear filters that strengthen (boost) or weaken (cut) specific frequency regions. While basic home stereos often have equalizers for two bands, to adjust bass and treble, professional graphic equalizers offer much more targeted control over the audio frequency spectrum. [71]
Otherwise, bass modulation became excessive and overcutting took place, with the cutter getting into the next record groove. When played back electrically with a magnetic pickup having a smooth response in the bass region, a complementary boost in amplitude at the bass turnover point was necessary. G. H.
Separate bass amplifiers which do not contain speakers, often called "heads" or "amp heads", are usually integrated units, with a preamplifier, equalizer (bass and treble controls) and a power amplifier combined in a single unit. Some bassists use separate preamplifier/power amplifier setups, where one or more preamplifiers drive one or more ...
The intent was to boost bass on quiet passages, and reduce the high-frequency tracing burdens (distortion) for the less-compliant, "ball" or spherical-tipped playback cartridges then in use. With boosted bass, tracing demands could be reduced in part by reduced recording levels, sometimes supplemented by peak compression.
Sea Blue EQ; EQ in pedal form, designed to match the piezo-acoustic guitars and work as a booster addressing frequency bands with treble and bass controls that you don't find on your amp. As a result the pedal allows you to further EQ beyond what your amp provides, while not fighting its own EQ.
