For audio professionals and sound engineers looking to fine tune audio, the EQ7153 comes fitted with a variety of features that make it the ultimate addition to any sound lineup. To set it above the rest, the EQ7153 comes equipped with dual 21-band equalizers. With a whopping 21 bands, you have the ability to boost and cut output with unparalleled precision over an extended spectrum that accommodates audio from highs to lows. With an adjustable range of ±12 dB at each band you get the ability to fine-tune audio for as much as needed to get the perfect sound. An integrated direct EQ function and bass booster give you even more control of the music.

To easily incorporate it into standard audio controls setups, the EQ7153 comes with rack mounting brackets that can be removed when using the EQ7153 in different settings. The EQ7153 also comes with a fluorescent spectrum display that provides live feedback about input and output. Included controls also allow you to set output to match any setting and input. With a crisp minimalist design, LED readouts, and a sleek finish, the EQ7153 looks as good as it sounds.

Equalizers are an integral part of any audio setup. Human hearing is generally understood to range from 20 Hz to 20kHz—with 20 Hz corresponding to low bass sounds and 20 kHz corresponding to high-pitched sounds. When you setup an audio system output has the potential to be distorted by a variety of factors included equipment combinations, quality of speakers, and the nature of the venue itself. If distortion happens, key ranges of sound come across too weak or strong relative to other ranges resulting in output that no longer faithfully replicates sound and can even damage speakers.

If audio output encounters distortion increasing or decreasing the master volume won’t help. You need a way to increase or decrease volume at a specific frequency (pitch). Equalizers are created to do just that, and come with different bands that correspond to different points over the range of human hearing (e.g. 32 Hz, a lower bass frequency or 18 kHz, a high frequency). You can adjust these bands to increase or decrease output at a given point by some amount of decibels while leaving output at other spectrums unchanged. The result is output that overcomes issues created by distortion to give you a sound that faithfully replicates input.

When buying an equalizer two things matter: the number of bands, and the adjustment range. Many stereos come with bass and treble which effectively makes them a two band equalizer. It’s nice to adjust bass and treble, but these two ranges leave out a lot. With more bands you have more equalization points and the ability to adjust outputs in more ways to maximize output. When buying an equalizer figure out how much control you need and pick an equalizer with enough bands to give you the options you need. For most users a five or seven band equalizer will be more than enough but die hard audiophiles may want equalizers ranging up to 21 bands. In addition to the number of bands the adjustment range is also important. If you can only boost and cut output by five decibels you may be unable to adequately tailor the sound even with 21 bands. The best equalizers are those that give you a lot of equalization points and the option to substantially adjust output sometimes by as much as ±10 dB.
