LDAC 24bit96kHz Bluetooth transmission
The Topping E70 has the certification of Hi-Res Audio Wireless and LDAC. It uses the newest QCC5125 chipset to support LDAC/AAC/SBC/aptX/aptX LL/aptX HD/aptX Adaptive protocol by Bluetooth 5.1.
To get even better sound quality from Bluetooth, we abandon the buit-in DAC QCC5125 and connect its digital signal to ES9028PRO to decode.

Newest XMOS XU136 USB processor
USB input of Topping E70 has a wide range of compatibility: Windows 10, Windows 11, MAC, Linux, iOS, Android and it is plug and play. Only for Windows ASIO applications, you need to install the driver and set it up. The USB hardware is based on the newest XMOS XU136 and Thesycon custom driver (applicable to Windows; other systems are driver-free), which is stable and reliable.

Coaxial and Optical (Toslink)
The optical and coaxial input of Topping E70 supports up to PCM24bit192kHz and DSD Dop64 audio, which is suitable for digital turntables, disk players or game consoles.

Auto On/Off function
The Topping E70 has an automatic On/Off function. That means that it will automatically turn on and set to the input whenever a valid signal is provided. When the signal of the active input is not active for 1 minute, the Topping E70 will turn off automatically.

12V Trigger interface
The Topping E70 is equipped with a 12V Trigger interface, which has both active control and passive control. With a 3.5 mm to 3.5 mm cable, the Topping E70 can bue turned on and off synchronously with other devices equipped with a 12V Trigger interface. This is really convenient, especially when used with amplifiers, like L70.

Selectable XLR+RCA output options
The Topping E70 has balanced XLR output and single-ended RCA output ports. You can easily choose “XLR only”, “RCA only” or “XLR+RCA” output. The level of the XLR output can be changed from 4V to 5V and RCA output can be changed from 2V to 2.5V.

Preamplifier function
In addition to the DAC mode with a fixed output level, the Topping E70 also has a DAC+preamplifier mode. In this mode, you can control the output volume from -99dB to 0dB by the knot or by the remote control.
