Description
Palmer River PSPREE is an active stereo USB-C media DI box designed to connect laptops, smartphones, and tablets directly to professional mixers, stage boxes, and PA systems. It converts USB-C audio into two balanced XLR outputs with high-resolution D/A conversion up to 32-bit / 192 kHz. Galvanically isolated outputs help reduce hum and unwanted interference, while switchable Mic/Line output levels make it easy to match different input stages.
The RIVER Spree features a 6.3 mm TRS headphone output for direct monitoring or additional signal routing, along with SIGNAL, SYNC, and POWER LEDs for quick status checks. A ground-lift switch provides additional noise control, and the unit can operate from USB-C bus power or the included 18 V DC external power supply. With external power connected, USB-C power pass-through can simultaneously power a compatible smartphone or tablet.
Built for professional studio, touring, and stage applications, the Palmer RIVER Spree combines a rugged aluminum and steel powder-coated housing with compact dimensions of 5.51 × 5.04 × 1.97 inches and a weight of just 1.27 lbs. It offers a 20 Hz–20 kHz frequency response, 112 dB signal-to-noise ratio, and up to 18 dBu output level, delivering clean and reliable audio connectivity wherever USB-C devices need to integrate with professional audio systems.
