ADA MP-1 Owner’s manual
3.4 USING THE CLIP LEDS
Your MP-1 is digitally controlled. The MP-1 circuit is monitored in four points for clipping of
the digital controls to help you prevent unwanted kinds of distortion from coloring your tone.
Always pay attention to your CLIP LED's. If a CLIP light remains on while you play, you
should lower the value of the control that is indicated. If you like the tone that you have, you
can still keep that tone, but eliminate the unwanted clipping. For example, if the EO is
clipping, but you want the same EO curve, you can either lower the MASTER GAIN (signal
going into EO), or lower all of the EO values the same amount.
3.5 USING THE EFFECTS LOOP
The EFFECTS LOOP LEVEL control on the rear panel will allow you to achieve the quietest
possible performance, no matter what kind of effects you are using. The level control is
configured to insure that you have the same overall signal level whether the effects loop is in
or out. provided the effects in the loop are set for unity gain.
Follow this general procedure:
1. If you are using an effect with only one level control, set your effects device to
unity gain. You can test for unity gain by connecting the EFFECTS SEND to your
effect input, and running the effect output directly to your amp. Adjust the level on
your effects device so that you have the same volume when the effect is in or out.
2. Set the EFFECTS LOOP LEVEL at the highest possible setting without clipping
your effect's input.
3. If you are using a line level effect with two level controls, set your EFFECTS
LOOP LEVEL control to 1 o'clock (0 dB gain). Adjust the input level on your effect
to the highest possible setting without clipping, and set the output level control on
your effect to achieve unity gain in your effect. You can test for unity gain as
described in step 1.
4. Check for distortion and excess noise. If your effect is clipping, turn your
EFFECTS LOOP LEVEL control counterclockwise.
3.6 LOAD PRESET PROGRAMS
There are 29 factory preset programs (1-29) that can be loaded into the internal program
memory via the front panel. These can be loaded at one time, or they can be brought into the
MP-1 's working register one at a time (level 2 software). To load all 29 programs, press the
STORE button. The STORE button will blink. Press BANK, and while holding it down, press
1. Display reads "LP" (Load Programs). Programs 1 thru 29 will be erased and written over
by the preset programs. Reference section 6.0 MEMORY PRESET SETTINGS for
description of factory presets. To load just one program (level 2 software), press BANK, and
while holding it down, press CHORUS RATE. "P" will be displayed, indicating that a preset is
being recalled. Now select the preset you want by using
^ V. You may use or edit this
program without erasing any of your own programs, or you may save it by using the Store
sequence.
