The Clockaudio PSU-1205 is a universal, switched-mode power supply unit designed to provide regulated DC power for professional audio equipment, particularly condenser microphones, boundary microphones, and other peripherals that require phantom power or a specific low-voltage DC input. This power supply is engineered for reliability in both fixed installation and broadcast environments, featuring a wide-ranging input voltage capability that allows it to operate from any mains supply between 100 and 230 volts AC at 50 or 60 Hz. This auto-sensing input makes it an ideal companion for international touring or installations where power standards may vary. The unit converts the AC mains voltage to a stable, low-noise DC output, ensuring that sensitive audio electronics receive clean, consistent power free from fluctuations that could introduce hum or affect performance.

The PSU-1205 is constructed with a robust metal enclosure that provides electromagnetic shielding and helps dissipate heat generated by the internal switching circuitry. Its design prioritizes safety and longevity, incorporating protections against over-current, over-voltage, and short-circuit conditions. The DC output is delivered via a locking connector, commonly a 4-pin XLR or a proprietary plug that mates with Clockaudio microphone models, ensuring a secure connection that won't be accidentally dislodged. An LED indicator on the front panel provides a clear visual confirmation that the unit is powered on and operating correctly. The power supply is designed for continuous operation, making it suitable for 24/7 use in conference rooms, courtrooms, houses of worship, and broadcast studios where microphones are always active.

Installation is straightforward, with the unit typically designed for desktop use or optional rack-mounting with an accessory kit. Its compact form factor allows it to be discreetly placed near the equipment it powers. By delivering a dedicated, regulated power source, the Clockaudio PSU-1205 eliminates the dependency on mixer-provided phantom power, which can sometimes be inconsistent or insufficient for powering multiple microphones or units with higher current demands. This ensures optimal performance and reliability for the connected audio devices, contributing to a clean, professional audio signal chain.
