Galaxy Audio Setting up PA and Monitors - Manual (Page 3)

Suggestions for Better Monitoring.
A. Proper Placement - The most important factor.
1. Each performer that needs to hear needs his own Hot Spot.
2. The Hot Spot should be placed close enough to touch. The closer the Hot Spot is to you, the louder it is.
One of the primary advantages of to the Hot Spot is its ability to be placed close to the performer, so take
full advantage of this.
3. The Hot Spot should be placed behind the mic.
4. If one Hot Spot is substantially closer to a vocal mic, its volume may need to be reduced so that it will not
reduce the gain of the entire monitor system.
B. Use a unidirectional microphone. There are many good brands on the market, with a wide variance in the
amounts of rejection, so experiment with several, if possible.
C.Equalizing your system.
1. With all the mics at their working volume in the P.A., increase the volume of the monitors gradually until
they reach the point immediately before feedback - they should just ring. Cut the frequency level that is
ringing by 2 to 3 d13. Periodically talk through the system while repeating this process, until you either get
several notes ringing at once, or you start to have a reduction in quality from over equalization.
2. In high volume applications, reduce all frequencies below 150 Hz in the monitor mix. Since low notes are
non directional, they are not really needed in the monitors, as they can be heard equally well anywhere on
stage.
D. Distortion problems - If your Hot Spots are distorting, it is probably because your amp is running out of
power. Either use a larger amp, or reduce the bass frequencies in the monitor mix.
E. Do Not plug or unplug your Hot Spot while it is operating, as this may place a temporary short on your
amplifier, which could be damaging.
