Description
Features:
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.
