Whirlwind pcUSB

The Whirlwind pcUSB is a versatile 2-channel active USB direct box designed to convert digital audio from USB-equipped devices into high-quality, balanced analog signals. This allows seamless integration with professional audio systems such as PA setups and mixing consoles, making it ideal for live sound engineers, presenters, and musicians. Supporting 16-bit digital audio at sample rates of 32 kHz, 44.1 kHz, and 48 kHz, the pcUSB ensures clear and accurate sound reproduction.

It features dual XLR male connectors for transformer-isolated, balanced analog outputs, minimizing noise and interference during transmission. The device includes a stereo/mono switch for flexibility in signal routing and a ground lift switch to eliminate hum and ground loop noise. An input pad attenuates high-level signals by -20 dB, preserving audio integrity and preventing distortion. Powered directly from the connected USB device, the pcUSB requires no external power source, enhancing its portability and ease of use.

Designed for live sound reinforcement, presentations, and recording applications, the pcUSB ensures high-quality audio integration with analog systems. Its compact, durable design and professional-grade features make it an essential tool for any audio professional needing reliable interfacing between digital and analog audio environments.
