XDUOO XQ-50 PRO: Bluetooth Receiver 5.0 aptX-HD CS8406 DAC ES9018K2M

XDUOO XQ50 version PRO is a CSR8675 Bluetooth receiver with an integrated SABRE ES9018 DAC and CS8406 S/PDIF interface. This solution is ideal for using your purely analog devices (preamplifier / integrated amplifier / active speakers ) with your digital sources. The connection can be wired ( USB ) and wireless (Bluetooth 5.0). It also has a digital output for use with SPDIF devices that lack wireless connectivity.

The PRO version now has an OLED screen to display the metadata of your digital tracks during playback. It reads in real-time the active input, Bluetooth protocol, track number, track name, and its bitrate/sampling rate. 

Very practical, qualitative, and affordable, this receiver allows you to stream your music directly from your smartphone, tablet, or any other device with Bluetooth connectivity (transmitter). Its careful design allows it to offer a clean playback of your audio files.

Bluetooth 5.0 & aptX HD

Le XQ-50 PRO uses a Qualcomm CSR8675 Bluetooth chip. This is a major upgrade since the first version since the XQ50 PRO now supports SBC, AAC, apt-X, apt-X Low Latency, apt-X HD, and LDAC. Those protocols ensure fast and stable data transmission and guarantee high-quality Bluetooth audio playback. A Bluetooth antenna improves the maximum transmission distance.


The receiver is also equipped with a DAC ESS SABRE ES9018K2M chip for digital-to-analog conversion. This excellent chip helps to provide the most accurate reproduction possible.

Interface SPDIF CS8406

The output panel has an RCA stereo analog connector, a digital S/PDIF, and a Toslink connector. The digital output stage uses a SPDIF CS8406 interface chip. The device can also function as a USB DAC by connecting it directly via its USB-C port to a computer.
