Feature

●Bluetooth 5.0 & LDAC Transmission: The DX3 Pro+ is equipped with a newly developed QCC5125 Bluetooth chip that supports audio encoding such as LDAC/AAC/SBC/APTX/APTX LL/APTX HD. It transmits audio wirelessly and decodes with ES9038Q2M for a higher sound quality
●High Performance DAC Circuits: Adopts ES9038Q2M, meticulous design and attention to detail, the DX3 Pro+ achieves THD+N 0.00015% and faithfully reproduces the sound quality of the studio
●Plug & Play to make PC HIFI Source: The Dx3 Pro + uses a 2nd generation 8-core XMOS XU208, and the USB supports PCM32bit/768kHz and DSD512 native. Compatible with various HIFI systems. And all inputs are low jitter, so you can enjoy music more freely
●(Applications of NFCA Circuit and Decoding Amplifier) The DX3 Pro+ has a built-in NFCA headphone amplifier module, which is far superior to the industry and has low noise and low distortion. Connect the digital signal and earphone to the DX3 Pro+ and use it as a decoder + earphone, you can enjoy the details of your music


Description

Topping DX3Pro + Decode Headphone Amplifier
Features:

The DX3 Pro + provides two gains, +6dB and +19dB which greatly expand the range of earphones.

External high performance digital broadcast/mobile/tablet decoder

Headphone Amplifier/Preamp, Total 4 Output Modes

Connect Bluetooth to DX3Pro + and connect the amplifier, active speaker, or earphone to the output, it becomes a Bluetooth amplifier/Bluetooth decoder.

The DX3 Pro + has a simple preamp function that can be used to adjust the volume.

When you set the DX3 Pro + output to DAC output mode, the screen will show the current sampling rate and the volume remains 2rms output.
