MXR MC403 CAE Power System

The MXR MC403 CAE Power System is a premium pedalboard power supply designed in collaboration with custom rig legend Bob Bradshaw and MXR. This rugged, all-in-one unit is built to handle the demands of professional musicians, offering the flexibility and reliability to power an entire board or rack full of effects and electronic devices. With 16 fully isolated, linear-regulated outputs, the MC403 delivers clean, quiet power to a wider variety of pedals and devices than any previous unit, ensuring superior performance both on stage and in the studio.

Whether you need straightforward 9V and 18V DC, adjustable output voltages for vintage fuzz tones, or even 9V AC for power-hungry multi-effects, the MC403 has you covered. The heavy-duty construction, short-circuit protection, and versatile mounting options make it the go-to solution for serious pedalboard setups or rack systems. If you demand maximum flexibility, ultra-quiet operation, and bulletproof reliability, the MC403 is the ultimate choice for powering your creative rig.

Unmatched Flexibility & Versatility

With a total of 16 isolated outputs, including adjustable-voltage DC options, the MC403 is designed to handle everything from classic stompboxes to modern digital processors. You can power multiple pedals requiring different voltages and current draws, all from one central hub, eliminating the need for multiple wall warts and reducing cable clutter. This makes it ideal for complex pedalboards or studio racks where versatility is a must.

Ultra-Clean, Reliable Power

The MC403 uses high-performance toroidal transformers and linear regulation on all DC outputs for whisper-quiet, stable power. Each output is fully isolated and short-circuit protected, minimising noise, ground loops, and risk of pedal damage. Whether you’re using vintage analog or modern digital pedals, your effects will sound their best every time you power up.

Adjustable Voltage for Creative Tone Shaping

Two dedicated adjustable outputs let you fine-tune voltage between 6.5V and 15V, perfect for simulating dying battery tones with transistor-based fuzz, overdrive, or distortion pedals. Simply adjust the knob and selector button to tailor the voltage for classic, sputtery sounds or high-headroom clarity, unlocking new tonal possibilities from your favourite effects.

Built for the Road (or Studio)

Enclosed in a robust, heavy-duty chassis, the MC403 is ready to withstand years of touring abuse or regular studio use. The unit can be securely mounted on your pedalboard or rack-mounted using the included bracket, adapting to any rig configuration. With simple operation and clear LED indicators for each output, you’ll always know your pedals are powered and ready for the show.
