Full Synchronization Technology
PLL+TCXO
Low temperature drift, low frequency drift, ultra low phase noise, frequency stability is lower than 1ppm. With the full synchronized clock, the distortion is even lower and sound reproduction is more realistic.
Full Balanced Output
Differential operation amplifier is used on each channel with fully balanced output design.
2.5mm balanced, with true mirrored architecture the distortion and crosstalk is lowered.
The New Mango OS
The new Mango OS is still based on Linux, but it has been greatly minimized, optimized and dedicated for playing music. The GPU has been implemented for the UI to lower the CPU burden. With the Open GL real-time rendering, the UI response has been greatly improved.
The DX120 uses DMA to process background I/O tasks. This frees up the CPU, and allows the CPU to work better and more efficiently for decoding. This also enhances the response speed of the entire audio path increasing real-time functions allowing for close to instant real-time. Use of the DMA lowers the process burden of the CPU.
The Lowest Distortion AK4495 Player
The DX120 development focused on obtaining the most out of the AK4495 DAC chip. The specifications for the AK4495 show a THD+N of -105dB. In real practice obtaining this THD+N can be very difficult. However our engineers, through hard work utilizing intelligent design and research, have reached a THD+N of -111dB!
The Former Flagship DAC AK4495
THD+N: -105dB (Analog Block Power Supply 7V) DR, S/N: 123dB (Mono mode: 126dB）5.6MHz DSD Input Support
XMOS XU208 USB Receiver
With Thesycon driver, a full function USB DAC.
TI BQ25890 MaxCharge
Support for Qualcomm &MTK PE+ dual quick charge.
PLL+TXCO
Phase Noise ≤−145dBc/Hz（Offset 100kHz）Period Jitter ≤35ps rms
Frequency stability is 1ppm
The full synchronization technology has also lowered the phase noise.
Gold-plated PCB. Shielding for the digital section and analog section. Symmetric topology.
Dual Quick Charge & USB Type-C Port
The DX120 has both of the QC2.0 and the MTK-PE quick charge solutions. This supports 12V, 9V /1.5A quick charge and compatible with 5V USB charging. A full charge takes only 2 hours with quick charge.
In form and function the DX120 is like a fine sports car, fast, responsive, sleek of line with power to spare. The Output power of the DX120 is up to 400mW with 32ohm load. It is plenty of power.
