Can support Android phones, but not all, because of some software system versions, manufacturer hardware design, chip incompatibility, OTG, etc. Support system: 1: WIN7, WIN8, WIN10, (need to install the driver we provide). Note: XP is not supported. 2: Native MacOS uses the system's own drive Supported sample rates: PCM: 16/24/32 bit 44.1/48/ 88.2/ 96/ 176.4/ 192/ 352.8/ 384KHZ. DSD: 64/128/256QSD256 required version FB2000 support) Power and signal input:Type-C interface Volume adjustment:Computer adjustment, volume button adjustment Analog output:3.5MM headphone illustrate in detail: 1: PCB is designed with double-layer immersion gold technology to good current and current Pass performance 2: Crystal oscillator 3: Have their own development program, complete chip optimization, signal integrity Better, less signal distortion 4: Dual op amps are used, and the op amps are powered by positive and negative power supplies. 5: Product size 100 x 31.5 x 10mm decoding, The ES9038Q2M is a high performance 32bit stereo audio D/A converter. Using the 32-bit Hyperstream architecture and time domain jitter canceller, it provides DNR up to 129DB, and +N of 120DB. Supports synchronous and ASRC modes. USB solution, USB digital control chip, support 32-bit 384Khz and native DSD256 (Native DSD), in the , when using ASIO output, can support DSD256. The OS system is driver-free and the output is 32bit 384Khz, plug and play. Op amp power amplification output, The pre-stage voltage amplification uses a low-noise, low-power precision audio operational amplifier OPA1612 that TI has been selling for many years. The latter current amplification is a more classic AD8397. Color: Black Material: Metal Package Contents: 1 * Decoder Only the above package content, other products are not included. Note: Light reflection and different displays may cause the color of the item in the picture a little different from the real thing. The measurement allowed error is +/- 1-3cm.
