Desktop-grade DAC<\/h2>\n

ESS SABRE PRO – Flagship Series ES9027PRO<\/p>\n

Features a fully differential audio architecture with 8 channels in parallel, paired with dual-channel ultra-low noise regulators (ES9312) to precisely match the output of each channel. Optimized power efficiency and reduced clock jitter significantly improve audio signal fidelity.<\/p>\n

*The ESS SABRE PRO series DACs are primarily used in high-end audio systems and professional audio equipment. The latest generation includes the new flagship series ES9039PRO and ES9027PRO.<\/p>\n

<\/h6>\n

6 Ti Audio Operational Amplifiers<\/h2>\n

New Combination – High-Energy Stable Output
\nThe preamplifier uses two low-noise audio operational amplifiers, OPA1692, paired with four wafer-level high-precision matched INA1620s for power amp driving. Based on a specially designed internal layout, crosstalk is significantly reduced, and even under overdrive or overload conditions, it is unaffected by inter-channel interactions, ensuring excellent dynamic range under various load conditions.<\/p>\n

Each INA1620 features:
\n8 0.004% high-precision matched thin-film resistors
\n1 on-chip EMI filter
\n1 low-distortion, high-output-current dual-channel audio operational amplifier<\/p>\n

Patented Desktop Mode<\/h2>\n

Self-Adjusting and Scheduling, Balancing Efficiency and Power Consumption<\/p>\n

Thanks to its new configuration, optimized circuit architecture, and more efficient heat dissipation, the QX13 delivers powerful output comparable to a desktop amplifier in desktop mode, while significantly reducing power consumption. It also features a built-in high-precision power meter that accurately determines the power supply capability of different USB front-ends, intelligently adjusting the headphone amplifier’s power supply, gain, and output power.<\/p>\n

Patent No.: ZL202321946664.8<\/p>\n

Front Type-C Interface: Data Transfer + Power Supply Interface
\nSide Type-C Interface: Dedicated Interface for External Independent Power Supply<\/p>\n

<\/h6>\n

Digital-Analog Separation, Multi-Layer Masking<\/h2>\n

The design separates the digitizer and analog board, equipped with a mask for isolation. This effectively ensures the accuracy and dynamics of signal processing while effectively absorbing and conducting heat for efficient heat dissipation, ensuring the QX13 can deliver sustained high-performance output.<\/p>\n

<\/h6>\n

XMOS XU316 Core, Ingenious Design<\/h2>\n

Professional-grade USB AUDIO performance, high performance, low latency, supporting 768kHz\/32bit, DSD512 (Native) decoding specifications; paired with dual ultra-low phase noise, low-temperature femtosecond crystal oscillators, it stably adapts to various audio sources and sampling rates. A 10-band lossless PEQ adjustment has also been developed based on the XMOS XU316, supporting adjustment via Web* and the Android FIIO Control APP, allowing for easy tuning.<\/p>\n

<\/h6>\n

Professional Audio Architecture, Comparable to Professional Decoding Amplifiers<\/h2>\n

The QX13 condenses the signal processing of mid-to-high-end decoding amplifiers into a small dongle, achieving high-precision conversion from frequency multiplication digital audio to DAC. It also features multi-stage analog audio processing including LPF voltage amplification, BUF current amplification, and parallel enhanced current amplification, delivering sound quality comparable to professional decoding amplifiers.<\/p>\n
