Distortion can come from a few different sources:
1. The mics you're using were not designed to record very loud sounds
and they are distorting.
Solution: use mics that are designed to handle the high sound pressure
levels.
2. Assuming that the level coming out of the microphones is within the
range that the recorder's mic pre-amp is designed to handle, you might
be setting levels (as indicated on the meters) too high, resulting in
the A-to-D converter max'ing out (digital clipping).
Solution: set the levels so that the indications on the meters never
exceed the "0" level. If the recorder has a limiter or an Automatic
Gain Control (AGC), you might consider using provided that you realize
the tradeoffs in sound quality a limiter/AGC will introduce. Keep in
mind that you'll usually get better sounding recordings if you set the
level manually and don't use a limited or AGC.
3. The mics may be putting out a level that exceeds the mic pre-amp's
input level, resulting in mic pre-amp overload distortion. Since the
recorder's level control and the meters are after the mic pre-amp in all
current recorder's you, will have no indication of the mic pre-amp
overloading.
Solution: if your recorder has a low sensitivity (-20 dB) switch, use
it.
Or if the music is very loud, use the Line level input instead of the
Mic input (the line level input is typically accepts signals 20 to 30 dB
higher than the mic input). Keep in mind that the Line input has a much
higher impedance than the Mic input so filters (e.g., a bass roll-off
filter) that work fine into the Mic input might not work into the Line
input.)
Or if the mics are self-powered, use an attenuator cable between the
mics and the Mic input. If the mics are powered by the recorder
("plug-in power"), you can't use an attenuator cable.

Use your ears: stand where ever the sound is good.
I hope that this helps!
