SYSTEM POWER-UP
With any audio system you should apply AC power to components in the order of signal flow.
Turn on the first device in the audio chain first and the last device in the audio chain last.
When turning your system off, use the reverse procedure!
1. Turn the MP-l power switch to the "ON" position.
2. Turn on any effects units you have connected.
3. Turn on your power amp.
4. Select program number 1 on your MP-l.
5. 5. Set volume controls on MP-l, any connected effects, and power amp to the desired
playing level. In order to optimize the signaI-to-noise ratio throughout your system
you should adjust the input and output level controls so as to get as much signal to
each unit as possible without overloading.

through the rest of the parameters from left to right using the above method. If you have
something patched into the MP-1's effect loop and you want it to be "in line" for this program
you will set the EFFECT LOOP parameter to "IN", otherwise it will be bypassed. If you don't
want chorus on this program you will set the CHORUS RATE to 0. Note: with the CHORUS
RATE set at 0 the CHORUS DEPTH parameter will act as a notch filter. Changing the
CHORUS DEPTH value will change the notch filter point.
