where less gain would be required from the Console’s Input TRIM control. Use the +4 setting for all pro recording and live reinforcement
applications unless otherwise asked by a Engineer to provide a lower level signal. However, even in a pro environment, it is wise to
start with the MASTER controls in the Channels zero-ed out (all the way down) or if that is not possible due to critical stage levels or
acheiving a balance between the Channels, the STANDBY in the “0” position (switch down) to avoid surprising signal level accidents.

MESA FTSW

This 7-Pin DIN jack accepts the MESA JP-2C Custom Footswitch cable or any other standard 7-Pin DIN style Cable

should you misplace the included cable. The JP-2C Footswitch allows instant access to the three Channels, the two
Graphic EQs and the REVERB. It comes in very handy for those players who don’t use Midi to control their stage or studio
set up and also provides easy demonstration of the sounds and Features of the amplifier in Dealership environments.

NOTE: DO NOT connect any Midi devices to the Midi INPUT jack when using the MESA FT.SW. jack!!

To use the JP-2C Footswitch; Connect the 7-Pin Din Cable to the MESA FTSW jack on the Rear Panel (left most DIN jack when fac-
ing Rear Panel) making sure to line the pins up correctly with the guide on top and the pins on the bottom. Do NOT force the cable
into the jack! When the pins are aligned it will fit easily though snugly, into the jack.

Connect the other end of the 7-Pin DIN cable to the similar jack on the JP-2C Footswitch. The STORE LED will illuminate briefly
and at least one of the footswitch LEDs should light up upon connection of the JP-2C Footswitch. If not, unplug the cable and try
connecting it again making sure the pins are properly aligned. Check the amplifier connection as well to be sure the cable is seated
all the way home there also.

Use the JP-2C Footswitch to access the Channels, EQs and REVERB.

NOTE: You cannot use the JP-2C Footswitch and a Midi controller at the same time. Choose one or the other to control your amplifier
and DO NOT CONNECT THE JACK that corresponds to the switching method YOU DO NOT INTEND TO USE.

MIDI THRU/OUT

This 5-pin standard Midi jack is the THRU/OUT for the Midi control portion of the JP-2C. As you might guess,

any standard 5-Pin DIN cable will connect to this jack, though albeit, some fit more snugly (with difficulty at times) than
others due to the thickness of the plastic housing surrounding the Pin area of the cable.

Depending on your set up and whether the JP-2C is the first (only) device receiving Midi commands from a controller
in your system, or the one of many “downstream” in a chain of devices receiving Midi commands, the information will
either be from the master unit or a slave passing information on to the next in the chain. Either way, the JP-2C sends

all pertinent Midi information on as either THRU or OUT via this jack.

MIDI IN

This 5-Pin female DIN jack accepts standard 5-Pin Midi cables and passes all incoming Midi commands to the JP-

2C’s processor for interpretation. Whether from a Midi Footcontroller, Sequencer, Librarian Software or DAW, all Midi
messages sent to the JP-2C will be received here and, if pertinent, appropriate action will be taken by its processor.
The JP-2C can respond to Midi Program Change, Control Change and SysEx messages, but all Midi messages and/
or commands will be passed on via the THRU/OUT jack.

NOTE: DO NOT connect a footswitch to the MESA FT.SW. jack when using the Midi INPUT jack!!

MIDI CHANNEL

This mini detent pot allows selection of a specific Midi Channel among the 16 Standard Midi Channels. Set

the Midi CHANNEL pot so that it receives on the same Midi Channel as that which your Controller is set to send on. If it
is a guitar specific rig using Midi commands only for calling up Channels and Features on the amplifier, often players will
only ever use Channel 1 or Channel 16. This is easy to remember and stays out of the way for them, while leaving ample
room to grow a system that might get more complex sometime in the future. If it is to be used in a more expanded Midi
set up, you may have need for a specific higher Midi Channel number to isolate the data stream used to control different
instruments or a Computer used as a sequencer
