[QUOTE="Dick Rees, post: 124512, member: 16"] Re: Calibrating Monitors on stage Mauricio... To reinforce what Tim said: You can simply use an open mic (or mics) to quickly find the 3 or 4 "hot" frequencies of a room/system or stage/system setup. Put your mic(s) in the area of concern and set them to a good input level. Raise the mic/main level until the system starts to ring, then back off a tad. You can then simply "boost to identify" by raising the EQ faders one at a time (starting from the LF end), returning each fader to the neutral position if no ringing is encountered. If you hear a frequency start to "go" when boosting, you can then apply an appropriate cut to bring the response into a friendlier "ball park". If you have any EQ which is sweepable, you can put a 9dB boost on a filter, then sweep through the spectrum setting filters as needed...again starting with the LF end of things. As Tim said, find the 3 or 4 worst offenders and call it a day. Practice makes perfect. After getting comfortable with the process, you should be able to do this with a mix in a matter of minutes. It is admittedly unsophisticated but served many of us well over the years and is still valid. Much insight in how frequencies reinforce/cancel can be gained using this basic method. Please feel free to come back with any questions. Boost to identify, cut to taste... [/QUOTE]
