DX7 Pro+ uses ESS SABRE ES9038PRO, with 32bit Hyper-stream architecture, achieves ultra- high performance in the audio field. Each channel of the DX7 Pro+ will be arranged in parallel by 4 conventional balanced channels. This makes the performance of DX7 Pro+ even better.
A brand new I/V conversion circuit is designed for better quality audio reproduction. The unique circuit design provided lower distortion, lower noise while occupying less space. the new circuit is pushed close to limited of physics so that we are able to squeeze out the last bit of performance of the DAC chip. 

DX7 Pro+ has 3 output headphones jacks of 4-PIN-XLR, 4.4mm and 6.35mm to meet different usages. Besides, with the help of 2 gain setting, DX7 Pro+ could reach even wider adaption of different headphones. 

The encoder makes the step volume control more accurate and convenient. Even if the volume is adjusted to a small volume, there will not be any channel balance problems. 

DX7 Pro+ has the cerification of hi-Res audio wireless and LDAC. It uses newest Qcc5125 chipest to support LDAC/AAC/SBC/aptX/aptX LL/aptX HD/aptX adaptive protocol. To get even better sound quality from Bluetooth, we abandon the built-in DAC of QCC5125 and connect it's digital signal to ES9038PRO to decode.

The DX7 PRO + is equipped with a 12V Trigger interface, which can be set to active control (Trigger out) or passive control ( Trigger in). With only one easy-to-obtain 3.5mm to 3.5mm cable, the DX7 Pro+ can be turned on and off synchronously with other devices equipped with a 12V Trigger interface.
