Features:
- Details for MQA. It can get original music signal in recording studio. When the signal is recorded, it will "fold" the music signal to obtain a file size suitable for network transmission. This is called "Music origami". File for MQA can reproduce sound quality higher than CD on almost all devices. When used with the decoder for MQA, it can replay the original recording effect. Full Decoder for MQA. D70s uses the current highest level technology for MQA Full Decoder, which can fully expand the file for MQA to provide the highest sound quality of the file. At this level, you can accurately restore the artist's original recording in the studio.
- AK4497: SNR 122dB at 1kHz. Dynamic range 127dB at 1kHz. D70s measured distortion 0.0001% (-120dB), which has exceeded the official data -116dB.
- 2xAK4497 decoding chip. D70s uses an AK4497 for each channel, which achieves better channel separation and higher density sound than a single AK4497. At the same time, the indicator also broke the upper limit of a single AK4497.
- Bluetooth 5.0LDAC HD transmission: D70s is equipped with CSR8675 Bluetooth chip, for LDAC/AAC/SBC/APTX/APTX LL/APTX HD and other audio coding, so that high-quality audio can also be transmitted wirelessly. We even abandon the internal decoding of CSR8675, and connect the digital signal to 2xAK4497 to decode to obtain better sound quality. D70s therefore obtained Japanese Hi-Res Audio Wireless certification and for Sony LDAC certification.
- DSD512 & PCM768, improve effects. D70s uses the second-generation 16-core processor XU216 for XMOS, which brings USB input 32bit 768kHz PCM and DSD512 native high-resolution audio support. With the German driver for Thesycon (for Win 7 and higher), it is handier to play ASIO for Windows. MAC does not need to be driven. USB also supports full decoding for MQA, calmly coping with the new trend of high-resolution online playing.
- AK4118 receiver: AK4118 is currently the lowest jitter S/PDIF receiver with good compatibility. It is used for D70s fiber, coaxial, and AES reception. These interfaces all support 24bit/192kHz.
- CPLD. D70s joins programmable logic chip CPLD, focusing on clock processing and signal optimization. CPLD cooperates with femtosecond crystal oscillator to bring a lower Jitter effect than when only using femtosecond crystal oscillator; CPLD coordinated processing of digital signal optimization, effectively improving signal quality and stability.
- Rich input interface. AES, USB, Bluetooth, optical, coaxial, IIS input. Among them, USB and IIS support 32bit 768kHz and DSD512 native input, USB also supports for MQA decoding; AES, optical fiber, coaxial support 24bit 192kHz input; Bluetooth got certification for Sony LDAC and has 24bit 96kHz transmission capacity for LDAC.
- IIS input is highly compatible. The D70s HDMI IIS provides phase setting, DSD channel setting, and DSD indicator pin selection setting, which can be compatible with most digital interfaces with HDMI IIS interface output on the market. Note: Press and hold the SEL button to turn on the system to enter system parameter setting. IIS PHASE, IIS DSDR, and DSD FLAG are the parameters of the IIS LVDS interface. The IIS LVDS interface is not a universal interface. There is no unified standard in the industry. For compatibility, you need to check the definition of front-end IIS LVDS; in addition, this interface does not support computers, TVs and other standard HDMI output devices.
- Output can be selected individually. D70s has balanced XLR and single-ended RCA output, adapting to common transmission interfaces. It can be set to "XLR output only", "RCA output only" and "RCA+XLR output at the same time". It is more convenient for you to use when combining multiple systems.
- Supply voltage can be switched and the global voltage can be used. AC100-120V 50/60Hz uses 115V gear, AC220-240V 50/60Hz uses 230V gear.
- Use CPLD for clock management to reduce clock jitter and optimize digital signal quality. For XMOS XU216 provides high-resolution USB, and expand the file for MQA. OPA1612 op amp is responsible for I/V conversion and LPF, taking into account sound quality performance. For ACCUSILICON femtosecond crystal oscillator provides high-precision clock. It adopts two-stage voltage stabilization and a total of 8 voltage stabilization power supply structures. AK1110 low noise and low ripple voltage regulator chip supplies power for AK4497.
- DAC filter mode: D70s provides 6 filter modes under PCM decoding, and 2 filter modes under DSD decoding to realize fine-tuning of details. Attention: Not equivalent to tone function.
- Bluetooth decoder application: Connect the Bluetooth of your mobile phone, tablet, laptop to D70s, and D70s will become your Bluetooth decoder. You can easily enjoy the high sound quality and convenience brought to you by Bluetooth 5.0. If your device supports for LDAC transmission, you will get better sound effects.
- Decoder + preamp application: D70s has a built-in volume control function that can adjust volume from -99dB to 0dB, so you can directly connect D70s to power amplifiers, pure amps, and active speakers, and control the volume on D70s via remote control/button. Enjoy music more comfortably.
- Pure DAC application: D70s can also turn off volume control function and maintain full-scale level output, so D70s works as a pure DAC.

Package Included:
- 1 x Set of Decoder

Note:
- It is assembled and ready to use.
