Whirlwind pcUSB 2-channel Active USB / PC Direct Box

2-channel USB-in/ Analog-out Direct Box

Transform Your Portable Device's Audio Into a Balanced Analog Signal

Convert the digital audio from your USB-equipped device into a quality analog signal with the Whirlwind pcUSB. This direct box takes the audio on your laptop, smartphone, or tablet and transforms it into a balanced, transformer-isolated analog signal that you can connect to a PA or console. Experience great sound that's free of noise and distortion, thanks to a ground lift and pad. The 2-channel pcUSB runs in both stereo and mono.

Transforms your portable device's digital audio into balanced analog

The pcUSB's USB input is compatible with nearly any laptop, smartphone, or tablet, and operates at 16-bit/32kHz, 44.1kHz, and 48kHz sample rates. The pcUSB is also bus-powered, receiving power from the host device.

Eliminate hum and noise with the flick of a switch

If you experience hum or noise while using the pcUSB, move the GND/LIFT switch to the LIFT position. This disconnects the ground between the circuit and the XLR outputs' pin 1 to reduce the offending sound.

Runs in both stereo and mono

Signals are routed to their respective outputs when the pcUSB's STEREO/MONO switch is in the STEREO position. If the switch is placed in the MONO position, the left and right inputs are summed into a mono signal that's fed to both XLR outputs.

Built-in pad for taming distorted audio

At Sweetwater, we're serious about our sound. That's why we appreciate the pcUSB's PAD switch. If you experience unwanted distortion, move the PAD switch to the PAD position to attenuate your signal by 20dB.

Connect your device to a PA or console

The pcUSB's dual XLR outputs provide low impedance signals suitable for PA systems and consoles. This direct box's maximum output is -3.4dBV, balanced with a digital 0dBfs input signal.
