SYSTEM TUNING
Reading from left to right when looking at the face of your new
PAR-245 , the following are the frequency ranges;
BAND FREQUENCY
SUB 30 Hz - 66 Hz
LOW 90 Hz - 300 Hz
LOW-MID 430 Hz - 900 Hz
HIGH-MID 960 Hz - 4.6 kHz
TREBLE 6 kHz - 16 kHz
6) Looking at the Frequency/Q selection chart for the selected band,
set the switches on top of the PAR-245 to the frequency that is closest
to the peak (or dip) and has the highest Q. Turn the Boost/Cut control
counterclockwise until the peak (clockwise to correct a dip) comes in
line with your desired curve. (See pages 14 & 15.)
7) When the center frequency of the original peak (or dip) has been
brought down to where you want it, you may see that surrounding
frequencies are still higher than you want them. Select the closest
frequency to the original peak (or dip) that has a lower Q, and see if
you now have a smooth line through that band. You may have to try a
number of Frequency/Q combinations to get the best results.
4) If electronic crossovers are used, any large frequency sections
corresponding to your crossover points that are low or high should
be brought in line using crossover level controls or amp gain
adjustments rather than the equalizer.
5) To begin, you will probably see several peaks and dips in your
RTA curve. Find the lowest offending frequency, and choose the
appropriate frequency range control on the top of the PAR-245 .
