Flagship ESS9038Pro USB hard solution femtosecond clock fully balanced Bluetooth 5.1 decoder Product Description 1: The flagship chip ESS9038PRO has powerful sound quality and amazing resolution. 2: Bluetooth 5.1 lossless playback, LDAC high-definition bit rate transmission. Supported formats: SBC/APTX/APTX-LL/APTX-HD                      APTX-ADAPTIVE/LDAC Sampling rate: 24bit/96KHz 3: USB decoding Italian interface, support DSD512 PCM24bit/384KHz 4: There are as many as 7 kinds of filtering methods, with different op amps, so that the timbre can be varied. 5: Femtosecond clock crystal oscillator, a VCXO femtosecond crystal oscillator is used as the main clock of 9038PRO, which can make the sound quality more round and full and durable. 6: Independent amp module, with amazing separation, full of dynamics and stronger thrust. 7: High-precision regulated power supply module, the sound is more delicate and soft. The power supply is a cornerstone in the audio system. If the power supply is done well, then the distance Good sound quality is half the battle, we use high-precision linearity designed with fully discrete components Regulated power supply, single instantaneous output power can reach astonishing 10W, no matter it is big dynamic, Or heavy bass can be easily controlled, and the overall effect is improved compared to ordinary power ICs 50%, the sound is full and thick, the sound field is wide but not scattered, there is a degree of relaxation, and it can be retracted freely 8: Three fever op amps, MUSES02*2 + pottery seal AD827*1. After the comparison of more than 20 combinations of op amps by enthusiasts, the vocals are sweet, Wide sound field, rich details, high resolution, suitable for listening to pop music, human voice, Symphony and other styles of music 9: TCXO temperature compensated crystal oscillator (standard version) The DAC working crystal oscillator adopts TCXO temperature compensation crystal oscillator, which has low phase noise, low jitter, and high temperature compensation stability. Excellent performance indicators make the sound density high and the sound quality better. 10: The headphone outputs a large thrust, and supports large headphones up to 600Ω impedance. 11: Optical fiber coaxial connection to CD player/player, can solve DSD128, powerful performance, listen to a different music world. 12: The knob controls all output volume, which can be used as the current stage. Instead of using the volume IC method, we directly use software to directly control the volume of the DA decoding chip. This unique technology will not affect the sound quality at all. Product parameters Function support: Bluetooth, USB sound card, optical fiber, coaxial Output interface: RCA, 3.5mm headphone jack, XLR balanced Mode switch: short press the volume knob Bluetooth chip: QCC5125 (support sbc/aptx/aptx-LL/aptx-HD/aptx-Adaptive/LDAC) Bluetooth version: 5.1 USB Decoding Chipset: Amanero Italian Digital Interface USB parameters: up to 24bit/384KHz                     Support up to DSD512 (hard solution) Optical fiber decoding parameters: support 24bit/192KHz Coaxial decoding parameters: support 24bit/384KHz/DSD-DOP128 DA decoding chip: ESS9038PRO Op amp chip: MUSES02*2/Teramic seal AD827*1 Amp output: 800mW@16Ω/60mW@600Ω RCA maximum output level: 6Vrms Size: 230*200*56mm Q: Can I change my order info?
