Switchable dual DAC chips: Pioneering the world's first DAC chip switching technology, backed by a proprietary patent, adopts 2pcs of DAC chips – ESS9038Q2M and AK4493. The groundbreaking design enables users to enjoy the robust dynamics of the ESS9038Q2M or the refined tones of the AK4493, vastly enhancing personalized audio experiences and pioneering new frontiers in the HiFi realm. High-performance: Offering an exceptional SNR (≥117dB) and ultra-low THD of 0.0003%, ensuring the high-quality conversion of audio signals. PC-USB input supports 32Bit/384kHz transmission and DSD256 playback, suitable for users who pursue ultimate sound quality. Multiple inputs and outputs: Support Optical, Coaxial, and PC-USB inputs, compatible with audio sources such as mobile phones, computers, and digital players. With 2 sets of RCA and 2 sets of AUX outputs, providing users with a wide range of connection options, facilitating integration with various audio sources and playback devices, and adapting to different usage scenarios. Dual OLED display & Large volume knob: 2 PCS of OLED screens can display real-time sampling rates, volume levels, and decoding chip statuses, enhancing user convenience. Designed with an easy-to-use large-sized volume control knob, ensuring that users can make delicate and precise volume adjustments to meet personalized listening preferences. Exquisite and charming appearance: The top is designed with a glass window, showcasing the internal structure and augmenting visual effects. Equipped with remote control for easier operation; adopting CNC technology for integrated molding, combined with anodizing process treatment, meets modern aesthetics and a commitment to premium quality. The optical/coaxial inputs of Q11 utilize SPDIF protocol and do NOT support DSD formats due to transmission protocol limitations. Warm tips
1. For Win7, PC-USB only can be recognized when the driver is installed. For other systems, the driver is only required when playing DSD files.
2. Stereo RCA and 3.5mm AUX output can work at the same time, and the volume of the outputs is controlled simultaneously.
3. There are 3 working modes with 2 different sound effects, supporting simultaneous output of AK4493 or ESS9038Q2M to groups 1 and 2, or AK4493 output to group 1 and ESS9038Q2M output to group 2.
