Setting up EQ manually

ackcheng · 21st April 2004, 04:46 PM

Recently I came across a setup method for room correction using positive feedback as follows and wonder if anyone can give me some feedback

1. Lower each individual frequency by 12dB on the EQ and increase the total gain by 3 dB
2. connect the microphone to the mic preamp and than to the EQ
3. Increase the vol of the preamp until positive feedback
4. reduce the total gain on the EQ from 3 bB to O
5. So far we have made the preamp just about to have positive feedback
6. Now, starting from the high frequency, slowing increase the gain from -12dB to 0 dB and above until positive feedback
7. Once positive feedback is heard, the gain is stop and lower by 3dB
8. Setup the same way for all frequency and for each channel separatly.

Does this method work?

Hi,

If you are using digital EQ, may I humbly advise you to post same thread in the digital forum as well. My be one for the video forum just in case your EQ is used for HT.

Hope this can help,
Chris
