Bluetooth 5.0 LDAC transmission : DX3Pro+ has the certification of Hi-Res Audio Wireless and LDAC. It uses newest QCC5125 chipset to support LDAC/AAC/SBC/APTX/APTX LL/APTX HD protocol. To get even better sound quality from Bluetooth, we abandon the built-in DAC of QCC5125 and connect its digital signal to ES9038Q2M to decode.
NFCA circuit : The new DX3 Pro+ has the NFCA circuit optimized for this unit, giving the ultra low noise and distortion. It pairs with high sensitivity IEMs and power hungry high impedance headphones nicely.
Pre-amplifier function : Adapt to different usage scenarios, DX3 Pro+ has 4 output modes: Headphone Amp, Headphone Amp+ Line out, DAC, and Pre amplifier.
PA3s is the best power amplifier for DX3 Pro+: PA3s has RCA+TRS balanced inputs. When used with DX3 Pro+, the TRS balanced input can be used to input other audio sources. The output power of 80W x 2@4Ω, 10%THD+N, 65W X 2@4Ω, 1%THD+N can be adapted to most situations where speakers are used.
Bluetooth headphone amp / Bluetooth DAC application: Connect the Bluetooth of the phone, tablet or notebook to DX3 Pro+, and connect the power amplifier, active speakers or headphones to the DX3 Pro+'s output, then DX3 Pro+ becomes your Bluetooth Headphone amp / Bluetooth DAC. If your device supports LDAC transmission, you will get even better experience.
