Professional audio engineers have known for decades that a good EQ makes all the difference in how a performance is perceived. Although multi-band graphic equalizers have been around for a long time, they have changed very little… until now!

• The ULTRAGRAPH FBQ-PRO FBQ3102 takes the graphic equalizer a giant leap forward technologically, providing robust feature sets and our proprietary FBQ Feedback Detection System – at a price that makes them a must-have for anyone who records or operates a live sound system.

HOW DOES EQUALIZATION WORK?

Imagine the audio frequency range as a very wide highway with lots of “lanes”. Each of these lanes represents a specific frequency band.

• The lanes on the left side contain the really low frequency content, mainly bass,bass vocals, and the kick and tom drums
• The middle lanes make up the fundamental zone of most musical instruments and the male and female vocals
• The right-hand lanes have all the high-frequency stuff , such as snare drums,cymbals, higher pitched percussion instruments and the content that adds sizzle to the mix
