REAR PANEL:

PHANTOM POWER:

The coax power jack above the A.C. line cord can provide power to a Midi foot controller, through the 7 pin Midi

Midi Out jack on the foot controller. This negates the need for a clumsy power adaptor on the stage.
NOTE: 7 -Pin DIN cable will not fit into 5-Pin DIN jacks. Check to see that your foot controller accepts 7-Pin DIN cables and is wired
to accept Power in this manner...and of the proper voltage match to TriAxis' phantom power output.

SWITCH:

Switch Jacks 1 through 4 provide "Tip to Ground" function switches for controlling or activating external devices such
as the "Switch-Track" voicing features that are incorporated into MESA/Boogie Switch Track power amplifiers. They will also control

IN jack. This is accomplished by connecting an external A.C. to D.C. power
adapter of correct voltage and polarity for whatever type of foot controller
you are using to the coax jack on the rear panel of TriAxis.
The MESA/Boogie Abacus foot controller requires the following power
requirements: 12 Volts @ 500 ma, Tip = Ground and Sleeve = Positive.
Connect a 7-pin DIN cable between the Midi In jack on the TriAxis and the
the Abacus or similar foot controller. Then connect the next device's Midi
In jack to TriAxis Midi THRU jack.
TriAxis' Midi "THRU" and Midi OUT jacks mirror all incoming Midi mes-
sages. The "THRU" jack will not send Data Dump or other similar command
information. Use the Midi "OUT" for all such commands. The "OUT" also
sends Midi program change messages when the Program keys are used
on TriAxis' Front Panel.

that do not use momentary logic. If they do not
control a device that you own, we suggest calling
that devices manufacture for specific voltage re-
quirements, as TriAxis may not provide "ground"
needed to control the particular device.
