ULTRAGRAPH PRO FBQ6200/FBQ3102/FBQ1502 Audiophile 31-Band and 15-Band Stereo Graphic Equalizer with FBQ Feedback Detection System Effects of Equalization on Music and Voice Reproduction Center frequency (Hz) 1/3 octave 31 to 63 80 to 125 160 to 250 315 to 500 630 to 1 k 1.25 k to 4 k 5 k to 8 k 10 k to 16 k Effects on music Fundamentals of bass drum, tuba, double bass and organ. These frequencies give music a sense of power. If over-emphasised they make the music "muddy". The 50 or 60 Hz band is also used to reject AC mains hum. Fundamentals of lower tympani. Too much boost produces excessive "boom". 100 or 125 Hz are also used for hum rejection. Drum and lower bass. Too much boost produces excessive "boom". Also useful for 3rd harmonic mains hum rejection. Fundamentals of strings and percussion. Fundamentals and harmonics of strings, keyboards and percussion. Boosting the 600 to 1 kHz range can make instruments sound horn-like. Drums, guitar, accentuation of vocals, strings and bass. Too much boost in the 1 to 2 kHz range can make instuments sound tinny. Too much boost anywhere between 1 to 4 kHz can produce "listening fatigue". Accentuation of percussion, cymbals and snare drum. Reduction at 5 kHz makes overall sound more distant and transparent. Reduction of tape hiss and system noise. The 1.25 to 8 kHz governs clarity and definition. Cymbals and overall brightness. Too much boost causes sibilance. Reduction of tape hiss and system noise. Center frequency (Hz) 1/3 octave 40 to 125 160 to 250 315 to 500 630 to 1 k 1.25 k to 4 k 5 k to 8 k 10 k to 16 k Effect on voice Sense of power in some outstanding bass singers. Voice fundamentals. Important for voice quality. Important for voice naturalness. Too much boost in the 315 to 1 kHz range produces a telephone-like quality. Voice fricatives-accentuation of vocals. Important for speech intelligibility. Too much boost between 2 and 4 kHz can mask certain speech sounds e.g. "m", "b", and "v" can become indistinguishable. Too much boost anywhere between 1 and 4 kHz can produce "listening fatigue". Vocals can be highlighted by slightly boosting the vocal at 3 kHz and at the same time slightly dipping the instruments at the same frequency. Accentuation of voice. The range from 1.25 to 8 kHz governs the clarity of voice. Too much boost causes sibilance.
