The Soundcraft CPS2000 is a dedicated external power supply unit engineered specifically for the Soundcraft MH4 series of professional mixing consoles. This unit serves as the primary power source, delivering clean and regulated DC power to the console via a proprietary link cable. Its external design is a strategic choice, effectively isolating heat and potential electrical noise generated by the power supply from the sensitive audio circuitry within the mixer. This separation enhances the console's thermal management, overall reliability, and sonic performance by minimizing the risk of induced hum or interference. The inclusion of a specific link cable ensures a secure, locking connection that prevents accidental disconnection during critical operations.

Constructed within a robust steel chassis, the CPS2000 is built to withstand the rigors of both touring and permanent installation. It incorporates comprehensive protection circuitry, safeguarding against common electrical faults such as over-voltage, over-current, and short-circuit conditions. This protection is vital for preserving the console's internal electronics from damage due to power anomalies. The unit is designed for continuous operation and features adequate ventilation to maintain stable temperatures. For international use, it often includes a universal input voltage range or a selector switch, accommodating mains power from 100V to 240V AC, which simplifies touring across different regions.

As a replacement part, the CPS2000 package provides a complete solution for restoring a failed power system or serving as a ready spare. For system technicians and rental companies, having this dedicated power supply on hand is crucial for minimizing downtime, as power modules are among the more common points of failure in any electronic system. By ensuring a consistent and filtered power feed to the MH4 console, the CPS2000 plays a fundamental role in maintaining the console's operational integrity and the pristine audio quality the series is known for.
