Description

RIVER spree

USB-C to studio and stage.

Feed audio from a laptop, smartphone or tablet directly into a mixer, stagebox or PA system. The Palmer SPREE is an active stereo USB-C media DI box designed exactly for this application.

It converts USB-C audio into two balanced XLR signals for direct integration into professional audio setups. D/A conversion with up to 32-bit / 192 kHz ensures high-resolution signal conversion, while the galvanically isolated XLR outputs help prevent hum and unwanted interference. A switchable Mic / Line output level allows easy matching to different input stages, and the ground-lift switch provides additional noise control in demanding environments. A 6.3 mm TRS headphone output allows direct monitoring or can be used as an additional signal output. Status LEDs for SIGNAL, SYNC and POWER provide quick visual confirmation during setup and operation.

The SPREE can be powered either via USB-C or via the included external power supply. When the external power supply is used, USB-C power pass-through allows the connected device to be powered at the same time. This is particularly useful for setups with smartphones or tablets.

With its robust metal housing, the Palmer SPREE is ready for touring and stage use. Engineered in Germany.
