Шо тебе сказать, за эти границы... у самого родичи в Волгограде, хоть через нет общаемся.
По делу, нашел еще некоторые свои записи. 1-я о ресете, 2-я о том как убрать хорус из-за задержки прямого сигнала, может поможет:

Is there a way to perform a hard reset of the MPX 1?
------------------------------
Yes, but this procedure will erase all user registers and
restore the factory default settings.
Turn MPX 1 off
Press and hold STORE and turn the unit on.
You should see a small case "d" in the display; release
the STORE button.
Press EDIT
You should now see a "0" in the display.
Turn the ADJUST knob clockwise until you see the
number "2" in the display.
Press STORE.
The unit will cycle through its reset


MPX 1 has a constant phasing sound ?
------------------------
Dry signal passing through the MPX 1 is delayed by
slightly under 2ms. When combining the dry signal
passed through the MPX 1 with the source signal there
will be a flanged effect. If you are using the MPX 1 with
a mixing console there is no reason to pass the dry
signal through the MPX 1, so it should be set up as
follows: Press SYSTEM and go to SYSTEM:MODES:MIX
and set for GLOBAL. Press MIX and set MASTER MIX to
100%. Your phasing problem should now be gone.
