Qing2 is our latest entry-level decoder. Due to our mature and advanced design, the Qing 2 is able to provide excellent performance at a relatively friendly price. Due to the cost constraints required for entry-level products, we have chosen to limit functionality while minimizing performance limitations. By removing some less commonly used features, users can obtain products with sufficient performance and functionality that can meet most application scenarios at this price.

Qing2 has the following characteristics:

1. Compared to the optional PCM or DSD versions required for Qing 1, Qing 2 has both PCM and DSD source decoding capabilities. The DAC module of Qing 2 has 4 sets of networks on the front and the same 4 sets of networks on the back, forming a fully balanced structure of 8 sets. Among them, four sets of networks constitute DSD decoding, which we call "vector stepper resistance network", and four sets of networks form an R2R structure for PCM decoding.

2. Compared to the DAC module of Meihequan 3, Qing 2 has eliminated the dynamic linear compensation circuit. Due to our mature and advanced technology, even after eliminating the dynamic linear compensation circuit, we can still achieve performance with SINAD of 106dB and DNR of 127dB. This performance is already very high for R2R, comparable to Quan 1 and Quan 2. For users who have a sufficient understanding of the industry's R2R indicators, they should know what these numbers mean.

3. The USB interface adopts our new generation high-performance USB interface equipped with L1 and L2 from Quan 3, with ground wire isolation function. DSD supports up to 1024, and PCM supports up to 1.536M. Our USB interface has been well received on Quan 3 and Mei, and users can rely on this built-in USB interface to achieve quite high sound quality requirements without considering adding an external USB interface.

4. The internal frequency up function has been removed, and only the widely acclaimed NOS mode has been retained, providing a natural and realistic listening experience. If customers prefer upscaling, high-quality software such as HQplayer can be used for upscaling. Due to the USB interface of Qing2 supporting DSD1024 and PCM1.536M, it is very suitable for software upscaling use.

The digital inputs of Qing2 include USB, I2S, coaxial (RCA), AES, and fiber optic. When the user inserts one of the digital signals, Qing2 will automatically recognize and lock it to that digital input. The analog output of Qing2 consists of one RCA single end group and one XLR balanced group. Please refer to the manual for specific parameters.
