This time we did it better
DX? Pro+ uses ESS SABRE ES9038PRO, with 32bit Hyper-stream architecture, achieves ultra-high performance in the audio field. Each channel of the DX? Pro+ will be arranged in parallel by 4 conventional balanced channels. This makes the performance of DX? Pro+ even better.
Brand new IN conversion
A brand new IN conversion circuit is designed for better quality audio reproduction. The unique circuit design provided lower distortion. lower A brand new IN 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 the limit of physics so that we are able to squeeze out the last bit of performance of the DAC chip.
Close to physical limits
The ability of DX? Pro+ to restore music has reached to THD+N<0.00006%.
That means more and clearer details you can hear.
Brand new design
The new family-style design that has won IF, reddot, and Goldenpin awards on DX5, combined with aluminum precision CNC technology, makes DX? Pro+ a better part of your desktop.
Built-in NFCA Headphone amp
The new DX? 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.

|---|---|---|
| 320, THD+N<1% | 3000, THD+N<1% | SNR |
4.PIN.XLR 4.4mm and 6.35mm
DX7 Pro+ has 3 output headphone 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. 
Step volume control
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 problem.
Multiple output Model
By double-clicking the volume knob, you can choose from four output modes:
“Headphone Amp”, “Headphone Amp + Line Out”, “DAC”, and “Pre-amplifier” to
adapt to more application scenarios.
| Output channel | Display | AMP output | RCA output | XLR output | Volume control |

Selectable OutPut
DX? Pro+ has balanced XLR output and single ended RCA output. You can choose “XLR only”, “RCA only” or “XLR+RCA” output for different applications.
IIS input supports up to DSD512 native
When there is a better interface, you can use the HDMI cable to directly send
the IIS signal into the DX7 Pro-E’s ESS9038PRO for better decode. IIS input
can support up to PCM32bit768kHz & DSD512native. The IIS input provides phase
settings, DSD channel settings, and DSD indicator pin selection settings,
which are compatible with most digital interfaces on the market that use the
HDMI interface to output IIS signals. 
This function uses only HDMI interface to transmit IIS signal instead of the standard HDMI signals. Thus it cannot be used for HDMI interface of the PC, TV, and set-top box.
Plug and play turn your PC into a HIFI source
DX7 Pro+ has a wide range of compatibility: Windows 10 and above, MAC, Linux, 10S, Android can be plug and play. DX7 Pro+ uses 2nd generation 8 core XMOS XU208, USB supports up to PCM32bit768kHz and DSD512 native.
LDAC 24bite Bluetooth transmission
DX7 Pro+ 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/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.
Sound Simulation
According to the unique harmonic performance of tubes and transistors, we
added the sound simulation function of tubes and transistors to the DX7 Pro+,
so that you can hear 3 different performance.
12 V Trigger Interface
The DX? 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 DX? Pro+ can be turned on and off synchronously with other devices equipped with a 12V Trigger interface.
