Power
This is a plug for connecting the Alesis Model P3 +9VAC power supply (supplied).
The power supply is then connected to an AC outlet delivering a nominal 120VAC.
The correct power supply must be used AT ALL TIMES. Any other power supply
might create a fire risk and/or permanently damage your unit. This damage would
NOT be covered under your warranty.
Footswitch
This is a 1/4" stereo phone jack which connects to one or two momentary (not
latching) footswitches, either normally-open or normally-closed.
• When one footswitch is plugged into the Footswitch jack, it will function as a
Bypass footswitch. When the Footswitch is pressed, the display will read “bYP”,
the display will dim, and the MicroVerb 4 will stop producing effects. If the
footswitch is pressed again, effects output will continue.
• Two footswitches can be connected if a simple adapter cable is used, similar to
an Insert cable:
When this setup is used, the footswitch connected to the Tip functions as a
Bypass footswitch. The footswitch connected to the Ring functions as a Control
footswitch. For more information, see Chapter 2, “Footswitch”.
