Jim Dunlop MXR MC403 CAE Power System
The MC403 powers more types of pedals and electronics at one time than any previous power supply.
The MC403 Power System-a collaboration between Bob Bradshaw and the MXR design team-is truly the ultimate power supply. The MC403 powers more types of pedals and electronics at one time than any previous power supply unit available. High quality, high performance toroidal transformers ensure quiet operation with superior performance capabilities. Designed for maximum flexibility, the MC403 can be used on pedal boards or rack mounted in a single rack space with the front mount bracket (included). All multi-tap outputs are completely isolated, linear regulated, and shortcircuit protected. Enclosed in a heavy-duty housing, the MC403 is designed for years of rugged road or studio use.
DIRECTIONS
(1) Set the red AC 115/230 input selector to your local AC voltage.
(2) Plug the included AC power cord into the AC IN jack.
(3) Connect the AC cord into a wall outlet.
(4) Flip the ON/OFF switch to the ON position. A red LED on the rear panel will light
up to indicate the unit is active.
(5) Read the OUTPUT GUIDE on the following pages to make sure you are using the
correct output jacks and cables.
(6) Connect pedals to the MC403 using supplied cables. The red LED above
each output jack will light to indicate that power is being supplied to the
connected pedal.
(7) An AC THRU jack is located next to the AC IN jack to provide auxiliary power
to another device. DO NOT EXCEED 200 WATTS on AC THRU device!
OUTPUT GUIDE
Before plugging anything into the MC403 Power System, check that the power
requirements of the device match the output capabilities of the MC403.
Specifically, you should check:
(1) The device’s voltage requirement to match the MC403 output voltage.
(2) Whether the device uses AC or DC.
(3) The current requirement to not exceed the MC403’s MAX CURRENT spec.
(4) The polarity when using DC power.
The cables provided with the MC403
support the industry standard positive (+)
barrel and negative (-) center polarity.
If you are unsure about what power your device requires,
DO NOT PLUG THE DEVICE INTO THE MC403! The following list provides usage
examples for each of the output types available on the MC403.
ADJUSTABLE DC OUTPUTS – Use 2.1 x 5.5mm black cables.
Push the red button IN for the high voltage (10.5-15V) setting.
Push the red button OUT for the low voltage (6.5-10.5V) setting.
Rotate the black adjustment knob to fine tune the value.
To simulate a dying battery tone on a transistor based distortion/fuzz/overdrive,
set the red button OUT and rotate the adj. knob until desired tone is achieved.
Radial™ Tonebone™ pedals requiring 15VDC, 400mA can be used with the red
button IN and the adjustment knob rotated fully clockwise.
9VAC OUTPUTS – Use 2.5 x 5.5mm red cables.
Line 6® Stomp Modeler and POD® units (excluding Pocket POD®)
9VDC OUTPUTS – Use 2.1 x 5.5mm black cables.
