Palmer RIVER SPREE – active stereophonic DI-box multimedia USB-C Palmer RIVER SPREE is a professional device designed for seamless integration of USB‑C audio sources with professional sound systems. Thanks to its active stereophonic multimedia DI‑box, it enables direct sending of sound from a laptop, smartphone or tablet to a mixer, stagebox or PA system without extra adapters or intermediaries. The unit merges a high‑quality digital‑to‑analog converter with isolated XLR electromagnetically powered outputs, ensuring a pure and interference‑free signal even in the most demanding stage and studio environments. Product Features Palmer RIVER SPREE stands out with a range of functions that make it an indispensable tool for sound engineers and musicians: Conversion of USB‑C audio signal into two symmetric XLR signals – direct connection of digital sources to professional audio equipment Digital‑analog processing up to 32 bits / 192 kHz – highest conversion resolution ensuring faithful reproduction of every sound detail Isolated XLR electromagnetically powered outputs – effectively preventing hum and unwanted interference Switchable Mic / Line output level – easy matching to different input stages of mixers and PA systems Ground‑Lift ground disconnect switch – additional control over noise in demanding working conditions Headphone output TRS 6.3 mm – direct listening or additional signal output LED indicators SIGNAL, SYNC and POWER – quick visual verification during configuration and operation Power via USB‑C or external power supply with power pass‑through – flexible power options in any situation Professional Capabilities for Your Creativity Palmer RIVER SPREE is a device created for those who need a reliable and high‑quality link between the world of digital sound sources and professional audio systems. Its active stereophonic multimedia DI‑box converts the signal from a laptop, smartphone or tablet into two symmetric XLR signals, enabling direct connection to a mixer, stagebox or PA system. Digital‑analog processing at 32 bits / 192 kHz ensures the highest possible conversion resolution, so every nuance of sound – from subtle vocal details to the full acoustic spectrum of instruments – is transmitted with full fidelity. One of the key advantages of the device is the isolated XLR electromagnetically powered outputs, which effectively eliminate network hum and electromagnetic interference. This feature is especially important in stage environments where numerous electronic devices and cables can generate unwanted noise. Thanks to Ground‑Lift the user gains additional control over removal of unwanted disturbances, allowing crystal‑clear signal regardless of conditions. The switchable Mic / Line output level allows immediate matching of the signal to the requirements of a specific receiving device. Whether you connect the DI‑box to the microphone input of a mixer or the line input of a stagebox, the switch lets you quickly and precisely set the appropriate signal level. The TRS 6.3 mm headphone output serves a dual function – it acts as direct playback listening from the source device, and also can be used as an additional signal output, increasing configurability. Palmer RIVER SPREE offers two independent power sources: it can be powered directly through the USB‑C port or via an attached external power supply. When using an external supply, the power passing (USB‑C power pass‑through) function allows simultaneous powering of the connected device. This is especially useful in configurations with smartphones or tablets that often have limited battery capacity and require continuous power during long events or recording sessions. The LED indicators SIGNAL, SYNC and POWER provide immediate status overview, greatly speeding up setup and making troubleshooting easier.
