Setting the SMEQ-1 levels
Setting an equalizer for the desired overall sound is a subjective topic. Experimenting with the controls is the best way to
learn and achieve good results. We recommend using headphones to evaluate the sound quality. Start with setting all
controls to the mid-point (flat= no gain or cut). We suggest you do this when the desired sound source is present (people
taking, being interviewed, etc.) Adjust each control clockwise and counter clockwise to get a feel for how each band
affects the overall sound. Keep in mind that the human voice resides in the 1Khz-6Khz range. To focus on these bands
the 60Hz, 150Hz, 400Hz and 10Khz controls can all be turned full counter clockwise. The remaining 3 controls (1Khz,
2.5Khz and 6Khz) can then be adjusted for best sound clarity and intelligibility. Note- turning any of the controls fully
clockwise will produce noticeable amplifier noise (a hissing sound).
