The Soundcraft DPS-3 is a dedicated external power supply unit engineered to deliver stable, reliable, and clean DC power to specific models within the Soundcraft GB and Live series of professional audio mixing consoles. These consoles, used extensively in live sound reinforcement, broadcast, and recording applications, require robust and consistent power to operate their analog and digital circuitry, microphone preamplifiers, and onboard processing. The DPS-3 is designed as an external unit, separating the heat-generating power conversion components from the sensitive audio electronics within the console itself. This design improves thermal management within the console, potentially enhancing longevity and reducing noise, while also allowing for easier serviceability and redundancy in mission-critical setups.

Constructed with a heavy-duty steel chassis, the power supply is built to withstand the rigors of touring and fixed installation. It employs a high-quality toroidal transformer, known for its efficiency and low electromagnetic interference, which is crucial for preventing hum and noise from being introduced into the audio signal path. The unit provides multiple DC output voltages required by the console, such as +/- 16V and +48V for phantom power, all regulated and protected against over-current and short-circuit conditions. Status indicators on the front panel provide immediate visual feedback on power and fault conditions, allowing technicians to quickly diagnose issues.

The DPS-3 connects to its compatible console via a multi-pin, locking cable and connector, ensuring a secure and error-free connection. For touring applications, its robust design helps it endure the physical shocks and vibrations of transport. For fixed installations, its reliability ensures the console remains operational for continuous, long-term use. By providing a dedicated, high-quality power source, the Soundcraft DPS-3 is an essential component that underpins the consistent performance and sonic integrity of the mixing console it serves.
