Palmer RIVER spree Active stereo USB-C media DI box

Description

The Palmer RIVER spree is an active stereo USB-C media DI box designed to connect laptops, smartphones and tablets directly to professional mixers, stageboxes and PA systems. It converts digital USB-C audio into two balanced XLR outputs, providing a purpose-built alternative to using a conventional recording interface in live and touring environments.

High-resolution D/A conversion at up to 32-bit / 192 kHz ensures clean and detailed audio reproduction, while galvanically isolated XLR outputs help prevent hum and unwanted interference. Switchable Mic and Line output levels make it easy to match the SPREE to different input stages, while the ground-lift switch provides additional control over grounding issues. A 6.3 mm TRS headphone output is also provided for direct monitoring or use as an additional signal output.

The SPREE can be powered directly from USB-C or from the included external power supply. When external power is used, USB-C power pass-through allows the connected laptop, smartphone or tablet to receive power at the same time. Status LEDs provide clear indication of signal, sync and power, while the rugged aluminium and steel housing makes the unit well suited to touring, stage and professional AV applications.
