Topping DX7 Pro+ Balanced DAC with Headphone Amplifier & Bluetooth

Topping DX7 Pro+ is a balanced DAC and headphone amplifier that is the upgraded version of DX7 Pro, giving improvement on the performance of the device.

It uses ESS SABRE ES9038PRO DAC and benefits from a 32bit Hyper-Stream architecture, achieving ultra-high performance in the audio field. Each channel of the DX7 Pro+ is connected in parallel by 4 balanced channels, allowing a better sound performance.

Brand new I/V conversion

Topping designed a brand new I/V conversion circuit, to achieve better quality audio reproduction. This unique circuit design provides lower level of distortion, lower level of noise, while occupying less space.

Built-in NFCA Headphone amplifier

The NFCA headphone amplifier has been optimized for the new DX7 Pro+, resulting in ultra low noise and distortion. It also work nicely with high sensitivity IEMs and power hungry high impedance headphones.

4-Pin XLR, 4.4mm and 6.35mm headphone outputs

For the headphones outputs, the Topping DX7 Pro+ offers two balanced outputs (XLR 4-Pin and 4.4mm jack) and one single-ended output (6.35mm jack).

Multiple output mode

By double-clicking the volume knob, you can choose from four outputs modes: “Headphone Amp”, “Headphone Amp + Line Out”, “DAC” and “Pre-Amplifier” to adapt to more application scenarios.

Selectable output

The DX7 Pro+ has balanced XLR output and single ended RCA output. You can choose “XLR only”, “RCA only” or “XLR+RCA” output for different applications.

I2S input

The Topping DX7 Pro+ has an I2S input with the HDMI connector and you can send the I2S signal to the ES9038PRO DAC for better decode. The I2S input supports PCM streams up to 32bit 768kHz and DSD512 native. The I2S input provides phase settings, DSD channel settings, and DSD indicator pin selection settings, making the DX7 Pro+ compatible with most digital interfaces on the market using HDMI interface to output I2S signals.

LDAC 24bit 96kHz Bluetooth transmission

The DX7 Pro+ has the certification of Hi-Res Audio Wireless and LDAC. It uses the newest Qualcomm QCC5125 chip to support LDAC/AAC/SBC/aptX/aptX HD/aptX adaptive protocol.

Tube&Transistor simulation

Inspired by the unique harmonic performance of tubes and transistors, Topping added a function that simulates them, in one single DX7 Pro+, this means that you can have 3 different audio performance: default, Tube Simulation and Transistor Simulation.

12V Trigger interface

The DX7 Pro+ is equipped with a 12V Trigger interface, which can be set to active control (Trigger output) or passive control (Trigger input). Using one 3.5mm cable, the DX7 Pro+ can be turned on and off synchronously with other devices equipped with a 12V trigger interface.
