QUATTRO Ⅱ is a new generation of multi-function DAC, ES9018S top level D/A chip, XMOS U Series Asynchronous USB interface, LME49600 ultralow distortion headphone AMP and LME49720 ultralow distortion opamp, support up to 32Bit/384kHz PCM and 1bit/DSD256 signal playback. The well-developed upgradeable digital processing platform, the new design dynamic display, full port DSD supported, at meanwhile the built-in preamplifier make it with more perfect sound performance and easier to use.
The newly designed digital system architecture, using MCU+FPGA hardware architecture, client can update internal XMOS, MCU, FPGA firmware through USB port, and easy to add new features to enhance the user experience.
The flexible FPGA for DSD signal decoding processing to make Optical, Coaxial, AES/EBU and USB interfaces support DSD signal playback, easy to connect various digital music player and music server with DSD output function, and support DoP, dCS, ASIO Native three kinds of DSD playback method, extensible platform enables more formats can be added in the future.
Internal preamplifier can be setting through the menu to enable, making XLR and RCA line output gain 10db boosted, with 0.5dB step 128 level precise volume control, when connecting pure power amp and monitor speakers no longer need to access additional preamp, you can get sufficient gain and smooth volume control curve.
Dual Optical input, dual Coaxial input, and the other total of 6 groups digital signal input port fully meet the needs of multi-connected devices. The original Auto Scan mode to quickly confirm the input signal is valid connection without having to select the input channel, achieve plug and play.
The new remote RM2 added separate channel selection buttons, easy to directly select the input channel, ultra-thin aluminum shell to have a good touch experience, drawer-type battery compartment design easier to replace the battery.
