Before you read this chapter, you might want to look at the rather lovely channel strip features on the previous page.
27. STEREO GRAPHIC EQ
This equalizer is used to shape the frequency spectrum of the main mix or monitor mix. It is the last thing in the signal chain before the MAIN MIX (34) faders and the MAIN OUT (5) jacks.
Each EQ slider controls a different section of the audio frequency range. Moving a slider up or down will boost or cut the output levels of signals around the slider’s center frequency. By setting all the EQ sliders to zero (center) you’ll effectively remove it from the signal path.
The following steps show how the equalizer can be used to reduce feedback:
1. Set the EQ sliders to zero |
(center) while the band |
plays on. |

2. | Set the channel GAIN (16) |
| levels, using the LEVEL |
| SET LED (17) and adjust |
| the channel faders for a |
| nice mix. |
3. | Slowly turn up the MAIN |
| MIX (34) faders until feed- |
| back just begins to occur. |
| BE CAREFUL! Feedback |
| can occur quickly and be- |
| come very LOUD, very fast. |
4. | Cut the appropriate EQ slider |
| until the feedback stops. |
Here are some general suggestions on using the EQ:
For better vocal sound, set the 250, and 12K sliders to +5. Note: Make sure the singer

is within 3 to 6 inches of the microphone. No amount of EQ can save a wandering minstrel.
For more presence, set the 3.5K slider to +5.
To warm up the overall sound, set the 1K slider to
REMEMBER, LESS IS BETTER.
