EQ TIPS

Here are some general EQ tips to try out:

Rock Kick Drum

A rock kick drum is usually EQ’d quite a bit to make it sound the way it

does on the radio. Usually an engineer will cut some of the low-

midrange, while boosting the high end and some of the lows. Here is a

setting to try on a close-mic’d kick drum:

• Select all frequencies below 100 Hz and boost 3 dB

• Cut 400 Hz by 8 dB

• Boost all frequencies above 4 kHz by 4 dB

Vocal Air

A popular effect on vocals is to boost the high frequencies to add "air" to the vocals. This effect is achieved by

boosting the high frequencies:

• Boost 16 kHz by 6dB

Eliminating Feedback

During a live performance, you may experience feedback if a microphone is placed too close to a monitor. However,

feedback often occurs at one frequency before it happens at others. You can "ring out" the monitor by using EQ to cut

the frequency that is feeding back. Try this when the band and audience are not present:

1. Insert the EQ between the mixer’s monitor output and the monitor amplifier.

2. Slowly raise the monitor level to the point of feedback. As soon as you hear feedback, turn the monitor level down,

but not off.

3. Select an EQ band that is near where you think the feedback is occurring. For example, if you’re getting high-

frequency feedback, try 6.3 kHz.

4. Slowly raise the 6.3 kHz band level while listening for feedback. If you hear feedback, cut that frequency. If you

don’t hear feedback, return that band to “0” and repeat this procedure with another frequency band.

5. If you don’t hear feedback at any frequency using this method, try boosting the monitor level a little more, and

repeat the process.

INSTALLING AEQ231 IN A RACK

AEQ231 can be installed in a standard 19" audio equipment rack (occupying one rack space). When you install it,

allow adequate ventilation behind AEQ231.

Note: Depending on the incoming

audio, you may need to reduce the

gain on some frequency bands to

prevent clipping.
