Palmer SPREE Aktive Stereo-Media-DI-Box + USB-C

Palmer SPREE Active Stereo Media DI Box + USB-C

Are you looking for a reliable way to feed audio from a laptop, smartphone, or tablet directly into a mixing console, stage box, or PA system? The Palmer SPREE Active Stereo Media DI Box + USB-C was designed specifically for this application and offers a practical solution for studio, stage, and professional audio setups. Via USB-C, the audio signal can be captured directly from the connected device and converted into two balanced XLR signals.

Especially when integrating digital playback devices such as laptops, smartphones, or tablets into an existing audio system, clean signal routing, ease of use, and a low-interference connection are essential. The Palmer SPREE Active Stereo Media DI Box + USB-C combines these requirements in a rugged unit and enables direct routing to professional inputs.

Manufacturer and Development of the Palmer SPREE Active Stereo Media DI Box + USB-C

The Palmer SPREE was developed in Germany and is designed for use in demanding environments. The rugged metal housing made of aluminum and steel ensures a sturdy construction, which is particularly advantageous for touring and stage use. The black powder-coated finish further enhances the device’s durable character.

Included accessories are rubber feet, a label plate, and a USB cable. This makes the Palmer SPREE Active Stereo Media DI Box + USB-C ready for typical setups where organized cabling, clear assignment, and reliable signal transmission play a key role.

Technical Details of the Palmer SPREE Active Stereo Media DI Box + USB-C

The Palmer SPREE is an active stereo media DI box with one USB-C input and two outputs. It processes USB-C audio and outputs it as two balanced XLR signals. The D/A conversion operates at up to 32-bit / 192 kHz, ensuring a high-resolution signal. The frequency response ranges from 20 Hz to 20,000 Hz, within ±0.5 dB.

The XLR outputs are galvanically isolated to ensure low-noise connections. This helps prevent hum and unwanted interference. Additionally, a ground-lift switch is available, which allows for further noise control in demanding environments. The isolated transformer operates with a transformer ratio of 1:1.

Connections and Signal Path

The input of the Palmer SPREE Active Stereo Media DI Box + USB-C is a female USB-C jack. On the output side, there are two balanced line outputs via 3-pin male XLR connectors. In addition, the unit features a 6.3-mm TRS headphone output that can be used for direct monitoring or as an additional signal output.

A switchable mic/line output level allows for adjustment to different input levels. This enables the Palmer SPREE to be flexibly integrated into various audio environments without losing the core functionality of direct USB-C audio integration. Status LEDs for SIGNAL, SYNC, and POWER provide quick visual confirmation during setup and operation.

Power Supply and Use with Mobile Devices

The Palmer SPREE can be powered either via USB-C or via the included external power adapter. When using the external power supply, the connected device can be charged simultaneously via USB-C Power Pass-Through. This is particularly useful in setups with smartphones or tablets when the device needs to be powered during operation.

The operating voltage ranges from 12 V DC to 18 V DC via the external power supply or 5 V DC / 500 mA via USB bus power. Power consumption is 5 W. With a width of 140 mm, a height of 50 mm, a depth of 128 mm, and a weight of 575 g, the Palmer SPREE remains compact yet sturdy.
