WHAT IS EQUALIZATION?
An equalizer boosts or cuts a frequency range. The Alto Professional AEQ215 is a graphic equalizer. Graphic
equalizers have fixed frequency bands that can be boosted or cut. The term "graphic" is appropriate because the
combined settings of the bands often resemble a curve or "graph."
The most basic level of control on a graphic equalizer is the gain setting for a given band. Each of the bands
represent a predetermined frequency range; its gain setting controls the amount of boost or cut for that frequency
range. A setting of 0 dB means that the signal will not be affected in the area of those audio frequencies.
Depending on the program material, boosting or cutting just one frequency can have a significant impact on the
sound. When all of the frequency bands are taken together, the impact can be huge.
Equalization can be used for:
Adjusting the character of an instrument, voice, mix, or effect
Cutting or boosting frequencies to make a source easier to mix with other tracks
Compensating for a less-than-ideal recording
Compensating for less-than-ideal room acoustics
Creating a filter effect
Eliminating buzz, noise, or hum
APPLICATIONS
AEQ215 uses balanced XLR, balanced 1/4" TRS and unbalanced RCA connectors. They can be interfaced in several
ways to support a variety of applications. Three common configurations are:
Main Mix Insert: EQ the entire mix.
Aux (Monitor) Out "In-Line" EQ the auxiliary outputs that feed stage monitors.
Channel Insert: EQ a single instrument (requires a TRS Insert cable)
For best performance, and to avoid unwanted noise or signal loss, use only high quality shielded audio cables.
For further details, please refer to the INSTALLATION AND CONNECTION section.
