Decoder TOPPING D70S MQA 2 * AK4497 Bluetooth 5.0 32 bit/768 K DSD512 DAC musicale Hi-Res Hi-Res con telecomando

TOPPING D70S MQA Decoder 2*AK4497 Bluetooth 5.0 32Bit/768K DSD512 Hi-Res Hifi Music DAC with Remote Control
Please note: The DAC's side has Voltage selector switch,115V is for AC 100V-120V 50/60Hz, 230V is for AC220V- 240V 50/60Hz. Before power on the DAC,please remenber choose the correct Voltage.
Features:
High Resolution Music
Support Native DSD510 PCM 32bit768kHz
 
Dual AK4497
We use one AK4497 working for one sound channel in D70. So thesound and channel separation will much better than the situation of using only one piece of AK4497.
AK4118 Receiver 
A44118 is the jitter lowest S/PDIF receiver at present.It has good compatibility which used to receive optical,coaxal, AES signals up to 24bit/192kHz.
 
Various Input Ports
D70 has various inputs: AES, USB, Optical, coaxal which all support up to 24bit192K input. And both USB and IIS support 32bit768k & DSD512 input. It' s worth mentioning that D70 is able to be compatible with the most of IIS signals by setting in the menu.
 
Selectable output port
D70 has both balanced XLR and single ended RCA output.It can be set as XLR output only, RCA output only, or both XLR and RCA output, which are much more conveniently for your usage in the multiple systems .
 
Voltage selector switch
115V for AC 100V-120V 50/60Hz, 230V for AC220V- 240V 50/60Hz.
 
D70 use 2 x ACCUSILICON femtosecond crystal to make the Jitter lower.
 
4 x 3300uF nichicon FW capacitance provide energy reserves for the AK4497, and 8 x nichicon Muse capacitance are coupling output signals of it.
 
The Ultralow-noise low- dropout linear regulators TPS7A4701 and TPS7A3301 provide power for D70, bringing you "a darker background".
 
The output circuit is built up with L ME49720 OP-AMP ,Vishay high precision resistor and WIMA capacitance,which providing you a better performance. 
 
DAC&Pre-amp
D70 has an internal volume controlling function which can adjust the volume from -99dB to 0dB. Thus you can connect D70 to amplifier, multicenter amplifier, or power speaker to enjoy the music with the remote control.
 
DAC Application
Volume controlling function also can be shut off.Then D70 keep the max output at 4Vrms(XLR)&2Vrms(RCA)output, it works as a native DAC.
