Bluetooth 5.0 LDAC. Hi-Res Audio Wireless and LDAC are supported with a Qualcomm QCC5152 chip. Unlike other DACs that decode Bluetooth codecs with the Bluetooth chip, the DX3 Pro+ uses the ESS ES9038Q2M chip for decoding for even better performance. _ Plug and Play. Simply plug the DX3 Pro+ via USB into your PC or Mac to enjoy all the benefits of a high-end DAC without the need for drivers. Only higher-end ASIO applications on Windows 10 require a driver. _ Low Noise NFCA Circuit. An optimized NFCA circuit provides powerful, distortion-free performance: 1800mWx2 @32Ω, 0.00015% THD+N. _ High / Low Gain Settings. Two gain settings (+6dB/+19dB) make it easy to adjust for the varying impedances of IEMs and full-sized headphones. _ Four Output Modes. Adapt to every listening situation with the DX3 Pro+’s four output modes: headphone amp, headphone amp + DAC, DAC, and preamplifier. _ Features : ESS ES9038Q2M DAC chip LDAC audio DSD512 PCM768kHz XMOS XU208 Built-in NFCA headphone amp Remote control _ Specification : Bluetooth 5.0 : Qualcomm’s QCC5125 Chip Bluetooth Codec : AAC, SBC, aptX, aptX LL, aptX HD, LDAC Decoding Chip : ES9038Q2M THD+N @1kHz (A-wt) : THD @20-200kHz (90kBW) : SNR : 122dB DNR : 122dB Output level : 2.1Vrms @0dBFS Noise (A-wt) : Channel crosstalk @1kHz : -137dB Channel balance : 0.3dB Output impedance : 20Ω
