HIFI-Q5 Hifi USB DAC Headphone Amplifier Supports Optical Optical Bluetooth USB Sound Card Input

HIFI-Q5 Hifi USB DAC Headphone Amplifier Supports Optical Optical Bluetooth USB Sound Card Input

Features:
- Hifi audio decoder: high resolution, high sampling rate, cost-effective.
- Powerful decoding ability to build a desktop music scene for you. The DAC adopts the ES9018K2M decoding chip from the United States, and supports DSD256/1bit and PCM 384kHz/32bit. Its resolution is strong, the sound is delicate and round, the extension is very good, and it is shocking! HIFI-Q5 can act as a bridge between computers, mobile phones, power amplifiers, speakers, and headphones, restoring a shocking exclusive concert hall for you!
- Powerful USB sound card chip: The USB sound card adopts Taiwan's SA9227A chip. It has powerful performance and high sampling rate. It can also support DSD256/1bit, and PCM up to 384Khz/32bit! Support system for Windows/Mac/Android, etc., and support laptops/tablets/mobile phones and other devices. It can output DSD source signal, imagine lossless music scene!
- Hifi Bluetooth chip: equipped with American Hifi QCC5125 Bluetooth chip, it supports version 5.1 (compatible with lower versions such as 5.0/4.2). For LDAC/aptX-HD/aptX-Adaptive/aptx-LL/aptx/AAC/SBC and other protocols. For LDAC protocol, its sampling rate can reach 96Khz, allowing you to enjoy the exclusive music scene with wireless, low latency and lossless sound quality!
- Imported headphone amp chip supports 300Ω headphones. It is suitable for mainstream headphones in the market. Using TPA6120A2 chip, in fact, the current feedback circuit, the slew rate is up to 1300V/us, the distortion is only 0.00014% THD+N, the signal-to-noise ratio and dynamic range are up to 120dB, the driving ability is strong, and the output current is up to 700mA, which can fit most of headphones on the markets.
- Dual headphone jacks: In order to be compatible with most headphones in the market, HIFI-Q5 is designed with 3.5mm and 6.35mm headphone jacks. Cooperate with professional headphone amplifier chip TPA6120A2 and op amp NE5532 to ensure high resolution, high thrust and audible sound quality.
- Operational amplifier socket design: The operational amplifier adopts NE5532, which has low distortion, low noise and large thrust. It also adopts an op-amp socket design, which is convenient for music enthusiasts to replace different op-amp chips to obtain a desired sound.
- Digital encoder to adjust volume: digital volume adjustment is adopted, which is uniform and smooth, effectively avoiding the bias and noise problems of analog potentiometers. The one-piece stamped metal knob and the embedded aluminum alloy brushed panel are seamlessly connected to smoothly control the volume. Press the knob at the same time to switch the input channel cyclically, and press and hold the knob to soft power off or power on.
- Premium components: Using German original polypropylene audiophile audio coupling capacitor (for WIMA), it makes the sound even better! Use relays to handle the pop sound when power is turned on and off.
- Professional audio configuration builds audiophile sound quality: QCC5125 + SA9227 + NE5532 + TPA6120A2
