OPERATING MANUAL AND USER GUIDE
Tuning the Room:
• The controls on the Equalizer provide level adjustment to frequencies in the audio
spectrum. You adjust them either louder (up) or quieter (down) to make the overall sound
in the room better.
• To tune the system to the room, it takes some practice and patience. You play PINK
NOISE through the system and adjust each frequency so that the response is the same
for every frequency. You can download pink noise and save it to CD or MP3/4 player.
• To effectively measure and adjust the system response, you will need a Real Time
Analyzer (RTA). This device displays the system frequency response. They are available in
rack mounted, hand held and software formats.
• When your ear gets calibrated, you can tune the system by ear.
• Using pink noise through the system and an RTA, adjust the frequency response of
the system to look flat. Minor adjustments by ear can be made later, but only minor
adjustments.
• Leave the EQ alone until the next gig or the room changes significantly. However, if it
changes too much, it is too late to run the above procedure and you must “do it by ear”
• Use the individual channel EQ on the mixer to get the music and vocals to mix properly.
A graphic equalizer is a very valuable tool for the traveling musician. It allows you to get
the best sound in a variety of venues. As we know, all rooms are not created equal. They
have their own personality. That is to say, your sound system will not sound the same from
room to room. Using the EQ correctly will help you maintain “your sound”.
