A new amplifier circuit
Different from the traditional integrated amplification circuit, the XP-2 BAL embeds the new OP+BUF structure allowing a balanced output power pushed to 320mW. Its two onboard chips, the Qualcomm CSR8675 and the XMOS XU208, guarantee the retransmission of clean and deep sounds, whether by Bluetooth or USB type C port.
Bluetooth 5.0 & NFC pairing
The XP-2 BAL supports the latest Bluetooth 5.0 version bringing many improvements in wireless transmission. Thus, the range allowed by this evolution is doubled, and the transmission rate can now reach 2Mbps. As for consumption, nothing to fear since this new version has no impact on this parameter.
This speed allows you to enjoy high quality audio playback and extremely stable transmission. In addition, this version also allows the device to detect radio frequency interference in the 2.4GHz band in order to modify the communication channel accordingly to preserve transmission performance.
It should also be noted that it supports, thanks to the Qualcomm CSR 8675 bluetooth chip, the Bluetooth protocols SBC, AAC, APTX, APTX LL, APTX HD, LDAC,, allowing excellent interoperability with your high fidelity sources as well as an excellent transmission rate and stability for accurate audio reproduction.
Finally, with the NFC pairing function, you can link your devices in one click and won't be bothered by a complicated pairing protocol.
Interface USB XMOS XU208
The xDuoo amplifier / DAC benefits from a high-performance XMOS XU208 USB interface. This works asynchronously and also supports high resolution files up to 32bit 356kHz in PCM and native DSD256. Something to really enjoy your favorite songs, without limit.
