BT Box S2 HD

Bluetooth 5.0 audio receiver

Audiophile wireless streaming now in high resolution!

The BT Box S2 HD is our next generation, high-definition Bluetooth receiver, using latest technologies like Bluetooth 5.0 and aptX-HD for elevating your mobile Bluetooth listening to true Hi-Fi stereo levels. Leveraging the increased Bluetooth 5.0 range and transmission bandwidth the new and advanced aptX-HD codec sounds crisp, detailed, dynamic and excellent at all times, even if the Bluetooth connection quality momentarily drops. This avoids typical lossy compression artifacts of other codecs. Drawing on Pro-Ject Audio System’s decades long experience in designing and manufacturing analogue turntables and Hi-Fi electronics, the dedicated high-quality analogue output buffer stage in the BT Box S2 HD ensures that the connection to your amplifier and loudspeakers is as robust and solid as it can possibly get. It is the ultimate fusion of cutting-edge digital and traditional analogue design principles.
