Producte acabatview
The MXR MC403 Power System, developed in collaboration with Bob Bradshaw and the MXR design team, is an advanced power supply unit engineered for musical pedals and electronic devices. It is designed to power a wide array of equipment simultaneously, offering superior performance and quiet operation through high-quality, high-performance toroidal transformers.
This versatile unit can be integrated into pedal boards or rack-mounted using the included front mount bracket. All multi-tap outputs are fully isolated, linearly regulated, and protected against short circuits, ensuring reliable and safe power delivery. Constructed with a heavy-duty housing, the MC403 is built for durability in demanding road or studio environments.

Característiques principals:
- Powers multiple types of pedals and electronics concurrently.
- Suitable for both pedal board and rack-mounted installations.
- Features high-quality, high-performance toroidal transformers for quiet operation.
- Robust, heavy-duty housing ensures long-term durability.
- User-selectable power input: 115/230 VAC, 50-60 Hz.
- All multi-tap outputs are isolated, linearly regulated, and short-circuit protected.
Configuració i instal·lació
Before connecting any devices, ensure the MC403 Power System is placed on a stable surface or securely mounted. The unit is designed for flexible installation on pedal boards or within a standard 1U rack space using the provided front mount bracket.
Power Input Selection:
The MC403 features a user-selectable voltage switch on the rear panel. Before plugging the unit into a power outlet, verify that the switch is set to the correct voltage for your region (115 VAC for North America, 230 VAC for most of Europe and other regions). Incorrect voltagLa selecció pot danyar la unitat.

Dispositius de connexió:
Connect your pedals and electronic devices to the appropriate output jacks on the front panel. The MC403 offers a variety of isolated outputs:
- Sortides de 9 V CC: For standard pedals requiring 9-volt DC power.
- Sortides de 18 V CC: For pedals requiring 18-volt DC power.
- 9VAC Outputs: For devices requiring 9-volt AC power.
- Adjustable DC Outputs: Two outputs with adjustable voltage (6.5-15.0 VDC) and current (up to 200mA). Use the small adjustment knob and the adjacent switch (HIGH/LOW) to set the desired voltage.
Assegureu-vos sempre que el voltage and current requirements of your device match the output you are connecting it to. Using an incorrect voltage can damage your equipment.
Instruccions de funcionament
Once all connections are made and the voltage selector is correctly set, plug the MC403 into a wall outlet. Turn on the unit using the ON/OFF switch located on the front panel. The indicator LEDs next to each output will illuminate, confirming power delivery.
Sortides ajustables:
The two adjustable DC outputs provide flexibility for pedals with specific voltage needs. To adjust the voltage:
- Ensure the unit is powered off or the specific output is not connected to a sensitive device.
- Use a small screwdriver to turn the "ADJ" knob to fine-tune the voltage.
- Flip the adjacent switch to select between HIGH (10.0-15.0 VDC) and LOW (6.5-10.0 VDC) ranges.
- It is recommended to use a multimeter to verify the exact voltage output before connecting your device.
The isolated outputs prevent ground loops and noise, ensuring a clean power signal to your effects.
Manteniment
The MC403 Power System is designed for minimal maintenance due to its robust construction. To ensure optimal performance and longevity:
- Neteja: Disconnect the unit from power before cleaning. Use a soft, dry cloth to wipe down the exterior. Avoid using abrasive cleaners, solvents, or excessive moisture.
- Ventilació: Ensure adequate airflow around the unit, especially if rack-mounted, to prevent overheating. Do not block ventilation openings.
- Emmagatzematge: Quan no l'utilitzeu durant períodes prolongats, guardeu la unitat en un lloc fresc i sec, allunyat de la llum solar directa i de temperatures extremes.
- Gestió de cables: Keep power cables and patch cables organized to prevent strain on the connectors and accidental disconnections.
Resolució de problemes
If you encounter issues with your MC403 Power System, refer to the following common problems and solutions:
| Problema | Causa possible | Solució |
|---|---|---|
| No power to unit / LEDs off | Unit not plugged in; Power switch off; Incorrect voltage selection; Blown fuse (internal) | Ensure power cable is securely connected and wall outlet is active. Turn ON/OFF switch to ON. Verify 115/230 VAC selector is correct. If still no power, contact support. |
| Device not powering on from an output | Vol incorrectetage/current output selected; Faulty cable; Device malfunction; Output overloaded/short-circuited | Check device's power requirements against the output specifications. Try a different output or cable. Ensure the device is functioning correctly. The outputs are short-circuit protected; disconnect and reconnect the device. |
| Humming or noise in audio signal | Ground loop; Interference from other equipment; Faulty power cable | Ensure all outputs are isolated. Check for proper grounding of all audio equipment. Try different power outlets. Replace power cables if suspected faulty. |
