Radial Sb-48 Dual Phantom Power Supply

The SB-48 utilizes a non-radiating charge pump circuit to create a stable, ripple-free 48 volt supply for active direct boxes and condenser microphones. It is powered by a single 15VDC 400 mA supply (included), with XLR inputs and outputs for each channel. Simply connect your microphones or direct boxes to the XLR inputs, and feed the outputs to a set of preamps or a PA system. This allows you to use your favorite powered microphone or active DI on stage, even when the venue doesnt have a reliable phantom power source.Provide phantom power for condenser mics48V or 12V power for specialty microphonesDual XLR inputs and outputsPowered via external 15V power supplyRadial Item No. R800 0149 00Get yours today; with the security of our many decades of experience and Sam Ash Music's efficient order processing, your satisfaction is guaranteed!

The Radial SB-48 Dual Phantom Power Supply is a compact and efficient solution designed to provide 48V or 12V phantom power to condenser microphones, active DI boxes, and other audio devices that require external power. This rugged and portable power supply is ideal for stage, studio, or field use, offering clean and reliable phantom power in a highly compact form factor. Below is a detailed description and a comprehensive overview of its features, design, and technical capabilities.

Dual Phantom Power Output (48V or 12V): The SB-48 features two selectable phantom power outputs: 48V and 12V. The 48V setting is the standard required by most modern condenser microphones and active direct boxes, while the 12V setting accommodates devices that require lower voltage. This flexibility makes the SB-48 versatile enough to work with a wide range of microphones and audio devices, ensuring optimal performance regardless of the power requirements.

The SB-48 is a dual-channel phantom power supply, meaning it can power two devices simultaneously. This is particularly useful for stereo microphone setups, two-channel recording configurations, or powering both a mic and a DI box at the same time. Each channel has independent power circuitry, ensuring clean, isolated power to each device.

Like all Radial Engineering products, the SB-48 is designed with portability in mind. Its small, rugged enclosure makes it easy to carry in your gear bag or mount in a rack for permanent installations. The compact size is ideal for mobile recording setups, live sound engineers, and musicians on the go. Despite its small size, the SB-48 is built to withstand the rigors of touring and regular use.

The SB-48 uses a high-quality, low-noise power supply to deliver clean phantom power without introducing hum or buzz into your audio signal. This ensures that your microphones and DI boxes perform at their best, with no degradation in sound quality due to power interference. The low-noise design makes the SB-48 ideal for critical recording situations where audio clarity is paramount.

Built to Radial's exacting standards, the SB-48 features a 14-gauge steel chassis that protects the internal components from physical damage and electromagnetic interference (EMI). This rugged design ensures that the SB-48 can handle the wear and tear of live performances, studio sessions, and on-the-road setups. It is engineered to last, making it a reliable tool for professionals who need dependable equipment.

The SB-48 is designed for straightforward, plug-and-play operation. It features two XLR inputs for connecting microphones or DI boxes and two XLR outputs for sending phantom-powered signals to your mixer, audio interface, or preamp. The device is powered by an external 15V power adapter (included), and operation is controlled by a simple on/off switch for convenience.

Each channel of the SB-48 has its own LED indicator, which lights up to confirm that phantom power is active and operating correctly. These indicators provide visual feedback, ensuring that you always know when phantom power is being supplied to your devices.

The SB-48 is ideal for a wide range of applications, from powering studio condenser microphones to providing phantom power for DI boxes on stage. Its versatility makes it suitable for broadcast, podcasting, live sound, studio recording, and field recording setups. Whether you're recording vocals, instruments, or dialogue, the SB-48 ensures that your equipment gets the power it needs for clear and accurate audio reproduction.
