USER INTERFACE CONTROLS
Output Level Incompatibility Problems are caused by a miss-match in output levels between woofers, midranges
and tweeters. In the above graph, the midrange output level is lower than what is needed to match the woofers
and tweeters. This is usually an easy problem to solve without the use of an equalizer.
Non-Equalizer Solutions
First try balancing the output between the midrange and tweeter. For this example, reduce the level of the
tweeter. If you have passive crossovers between the midrange and the tweeters, attenuate the level of the tweeter.
If you have an active system, balance the level between the midrange and the tweeter by raising the level of the
midrange. Once you have achieved a balance between the tweeter and midrange integrate the level of the woofer
by similar tuning techniques.
Equalizer Solutions
If you have followed the instructions above, there should be little need for equalization. However, if
equalization is still required, use the DEQ 30 as a cut only device to try to smooth out the non-linearity of the
system. Cut frequencies gradually starting with the center point of the problem area. Do not cut the centered
band to get the frequency response to the flat position for it will dip below when you change adjacent bands.
Periodically listen to your system during this process to make sure the changes you make do not adversely affect
the detail and sound quality of the system.
