- PC-USB supports 24Bit/192KHz. Not for U disk
- ESS9018 decoding chip
- OPA2134 op amp chip
- NE5532 op amp chip
- CM6642 USB chip
- TAP6120 headphone chip

Features:
- HiFi DAC has high resolution and high sampling rate
- Powerful decoding ability to build a desktop music scene. The upgrade adopts ESS9018K2M decoding chip, the resolution is stronger, the sampling rate is stronger, the warm and true details in the sound, and the shocking emotions are played clearly in the ear without reservation. DAC-Q5N can act as a bridge between computers, headphones, power amplifiers, and active speakers, restoring a shocking exclusive concert hall for you.
- Equipped with classic USB chip. The USB chip uses CM6642 to obtain higher lossless decoding capabilities, up to 24bit/192kHz, and compatible with computer systems for Windows/ Mac/Linux. It also supports mobile phone OTG function for decoding. *USB interface does not support U disk or mobile hard disk, system for Android needs OTG adapter. System for IOS requires camera kit (you need to prepare).
- Dual headphone jacks. In order to facilitate indoor desktop use, it is equipped with 3.5mm and 6.35mm interfaces, which can output simultaneously. Headphone amplifier chip TPA6120A2 and professional op amp NE5532P are used together with a protection circuit to ensure high sound resolution, while taking into account high thrust and durable sound quality.
- Imported headphone amplifier chip, which can support up to 300Ω headphones. The circuit design is based on the headphone driver chip TPA6120A2. TPA6120A2 is a current feedback amplifier circuit with a conversion rate of up to 1300W/μs. Distortion is only 0.00014% THD+N, 120dB dynamic range, 120dB signal-to-noise ratio. The driving force of TPA6120A2 is also very strong, with an output current of 700mA, which is enough to satisfy most earphones in the market.
- High-performance low-distortion operational amplifier combination. NE5532P driver chip with low distortion, low noise and high thrust. The low-pass filter part adopts professional audio op amp OPA2134 to ensure high sound resolution while taking into account the durability of the sound; and there is an op amp socket, which is convenient for users to change their own op amp to get a different sound.
- External adapter power supply is safe and secure. The whole machine is powered by a DC12V interface, and a secondary power conversion circuit is designed internally. The front and rear audio circuits are also independently powered. While effectively suppressing the power adapter ripple, it also avoids power supply crosstalk and provides a stable and low-noise power supply for the precision audio circuit.
- Multi-function DAC is compatible with most devices. DAC-Q5N is a multifunctional DAC and headphone amplifier, with PC-USB/optical/coaxial digital signal input. Compatible with most audio equipment, such as mobile phones, computers, TVs, CDs, players, etc. And with stereo RCA/6.35mm and 3.5mm headphone output.
- Using digital volume control, effectively solve the problem of analog potentiometer bias and noise. The metal volume knob seamlessly connects with the embedded aluminum alloy front panel to control your music comfortably. Three blue indicator lights on the front panel can be switched according to the different sound sources, and the vision and hearing are highly unified.
- Exquisite appearance, classic body. All-aluminum body，repeatedly polished by CNC, is added with anodizing and fine sandblasting, which is firm and texture. Four non-slip silicone feet are used at the bottom.
- The sound quality of professional audio architecture is upgraded. Reasonable circuit layout, selection of high-quality components, upgraded fiber base and circuit board. Redefine the high-quality sound of HIFI to ensure product quality and high-fidelity HIFI sound quality. TPA6120A 2+NE5532+OPA2134+ESS9018K2M+CM6642.
