AKG ASU4000 Remote Antenna Power Supply
The ASU4000 is a compact, rugged power supply engineered to support distributed antenna systems in wireless microphone installations. Its compact footprint and waterproof metal housing make it equally suited to permanent studio setups and mobile recording rigs that demand reliability in demanding environments.
Power Distribution & Connectivity
Operating from a 12 V DC input, the unit delivers 8 V to antenna components via 50-ohm BNC connectors, ensuring impedance-matched signal integrity across your wireless system. The lockable DC input prevents accidental disconnection during recording sessions or system reconfiguration.
Coverage & Construction
The 500 MHz to 865 MHz frequency range accommodates modern UHF wireless microphone systems across studio, location, and live recording applications. Rugged, waterproof metal construction and an on/off status LED deliver field-proven durability in environments ranging from controlled studio spaces to mobile recording trucks.
