5.2 Equalizer In Sound Reinforcement Systems
The EQU MKII Series Graphic Equalizers can be used in the sound reinforcement systems to:
Eliminate unwanted sounds, such as the 60Hz Hum noise.
Shape the sound by changing the frequency response of the track.
The following connection is probably most common field of application:
NOTE: Mono/Stereo Application
- Mixing Console
MIXING CONSOLE

CH1 OUT
CH2 IN

Main Inserts
- Line Instrument
From line instrument

To power amplifier inputs

Special effects like telephone sounds are done by cutting off the low end to 200Hz and the high end to 6KHz.
Allow you to modify the sound of the instrument if put EQU MKII Series Equalizer in line with a musical instrument.
you can brighten the sound, and body to a thin sounding instrument, or you can give the sound a totally different
character.
Fix a track that does not sound quite right, put the EQU MKII Series Equalizer in an effects send and return it to the
mix bus.

The EQU MKII Series Graphic Equalizer can be used on an entire mix "In-line" between a instrument outputs
and a power amplifier, and this is the basic application in the PA system to offer precise equalization control.
The EQU MKII Series Graphic Equalizer can also be used on a single instrument by connecting to a mixing
console's main inserts, esp for those consoles without built-in equalization circuitry.
