POWER-UP

When the amp is turned on, the default channel (CH2) is selected, all other functions are off, as is the STORE
LED. After half a second, the channel and other functions will be selected as per the toggle switch settings, and the STORE LED
will illuminate briefly.

MESA FTSW

NOTE: DO NOT connect any Midi devices to the Midi INPUT jack when using the MESA FT.SW. jack!
MESA FT.SW.: 7-pin female DIN jack accepts a male DIN cable, connect the Footswitch here.
When a JP-2C Footswitch is first connected, the amp's STORE LED and all of the Footswitch LEDs will illuminate briefly.
When a button on the JP-2C Footswitch is pressed, the STORE LED will flash quickly, indicating a button has been pressed.
The JP-2C Footswitch has a built-in cable check feature which is activated when the Midi Channel rotary DIP switch is set to Channel
1 (position '0'). So, if the JP-2C Footswitch cable is damaged at anytime, or there's a communications failure with the amp, all of the
JP-2C Footswitch LEDs will blink steadily, assuming it is still receiving power from the amp of course.
NOTE: EMERGENCY FAILSAFE FOR LOST JP-2C FOOTSWITCH CABLE!!! If the supplied 7-pin DIN FTSW cable is lost, a temporary
(for emergencies only) solution is to use a standard Midi cable, which must have all 5-pins connected as per the Midi specification.
The JP-2C Footswitch LEDs will blink five times when the JP-2C Footswitch is first connected to the amp, indicating there's a cable
issue, and the LEDs will remain off, but the buttons will still operate normally, allowing channel and other functions to be selected.
CONTROLLING MULTIPLE JP-2Cs: Controlling multiple amps with a single JP-2C Footswitch is easily accomplished by connecting
the JP-2C Footswitch to the MESA FT.SW. jack on one amp, and connecting the Midi THRU/OUT from this amp to the Midi INPUT on
a second amp. For a third amp, connect the Midi THRU/OUT from the second amp to the Midi INPUT on the third amp, and so on...
When controlling multiple amps as indicated above, only the amp with the JP-2C Footswitch connected should be set for Midi Chan-
nel 1, all the other amps should be set to any other Midi Channel. Additionally, the Front Panel toggle switches should be positioned
identically, from one amp to another.

MIDI INPUT

NOTE: DO NOT connect a JP-2C Footswitch to the MESA FT.SW. jack when using the Midi INPUT jack!
Midi INPUT: Standard 5-pin Midi DIN jack. Connect a Midi Footcontroller output or the Midi OUTPUT of another device to send Midi
commands to the amp, here. Phantom power for a Midi Footcontroller or any other device is not provided.

MIDI THRU/OUT

through this jack, unchanged, and can be sent to other Midi devices. It also acts as a Midi OUTPUT when sending a User Preset
Dump.
Midi THRU/OUT: Standard 5-pin Midi DIN jack. Any Midi commands received at the Midi INPUT are passed
