PERFORM A FACTORY RESTORE IN THREE EASY STEPS:
1. With the MARK 7 turned o, select CHANNEL 3, and set the EFFECTS LOOP, REVERB, and all
three CHANNEL EQ switches to the ON position, then engage and hold the STORE SWITCH while
powering up the amplifier.
2. Release the STORE SWITCH after the amplifier is turned on. The STORE LED will turn on, and the
Factory Restore will begin.
3. After a successful Factory Restore, the STORE LED will turn o, then it will flash once as the
amplifier’s MIDI Interface is automatically restarted.
A Factory Restore should take no more than 1 to 2 seconds to complete.
If the STORE LED begins to blink on and o quickly after Step #2, it indicates that the integrity of at least one of
the User Presets EEPROM Memory locations is becoming or has become compromised. The Factory Restore
has still been performed and completed, but the amplifier must be powered down and powered up again to
be used.
NOTE: If any switch listed in Step #1 is changed after the amplifier is turned on and while the STORE SWITCH is still engaged,
the Factory Restore will be aborted, and the amplifier will power up normally.
DIRECT ACCESS VIA MIDI CONTROL CHANGE
In addition to supporting MIDI Program Change messages, the amplifier also accepts MIDI Control Change
messages (also known as Continuous Controllers or CC messages).
When using a MIDI foot controller capable of sending MIDI Control Change messages, you can assign buttons
on the MIDI foot controller for direct access to the individual functions on the amplifier, which allows the MIDI
foot controller to act as a dedicated amplifier Footswitch.
Typically, you would use either MIDI Control Change or MIDI Program Change messages, but not both (see
the note below). Using MIDI Program Change messages saves presets in the amplifier’s memory but does not
allow direct access to the channels and other on/o functions from the MIDI foot controller. Using MIDI Con-
trol Change messages saves preset combinations within the MIDI foot controller’s memory and does provide
direct access to the amplifier’s Channels and other on/o functions.
NOTE: If you experience any odd or unexpected MIDI behavior, it is more than likely a result of the amplifier receiving both
MIDI Control Change and Program Change messages at the same time. Ensure this is not the case before contacting us
for support.
