Independently Developed FPGA Module:-
The Aquilla II features a self-developed FPGA module called YULONG JIC(Jitter and Interfacing control). It manages the USB audio signal processing, SPDIF signal demodulation, data FIFO buffering, Femtosecond clocks, and more. These technologies collectively provide an unmatched crisp sound output.
Pro-Grade DAC Chip:-
The Aquila II is equipped with a professional-grade DAC setup from Sabre Technologies, featuring ESS9038Pro. It is a 32-Bit, 8 channel flagship-level DAC from the brand capable of providing the best level of sound decoding and output. The device features dual decoding modes, synchronous mode, an asynchronous mode which you can freely switch in between. Via the USB input the device can decode PCM up to 32-Bit/768kHz, and DSD up to DSD512 natively. If you use other input methods like SPDIF, AES, Optical, it can decode PCM up to 32-Bit/384kHz, and DoP128.
Monstrous Output and PreAmp Mode:-
The Aquila II has monstrous output power, it has a power rating of up to 4000mW @ 32 Ohms through the balanced 4-Pin XLR port. Even its ports give a humongous power of up to 1600mW @ 32 Ohms. You can also use it as a PreAmp and give a fully balanced output via XLR ports. It also features unbalanced PreAmp output via RCA port. The device gives out more than enough output power to power the most demanding headphones with ease.
Multiple Input/Output Options:-
The Aquila II provides its users with a complete versatility to choose the input and output options. You can give input to it via USB, SPDIF, AES, and optical ports. And for the output, you have 4-Pin XLR balanced, 4.4mm, and 6.35mm ports on the front. It also features balanced XLR and unbalanced RCA output for connecting to different amplification systems. The ports have a low output impedance of ~2Ohms, making the device suitable for low impedance rated headphones. It is compatible with Windows, macOS, iOS, Linux, Android Smartphones, so you can connect it to whatever source that you have and enjoy high-quality music output.
IPS Display, Rich Build, Analog Volume Control:-
The Aquila II features an IPS display in the front with wide viewing angles. It shows active input type, active streaming clock, volume, active filter. It shows all the necessary details and also adds to the rich look of the device. The device is made up of high-quality aluminum alloy material.
