1. The USB uses VT1630 producing from Weisheng, a big manufacturer in Taiwan, with stable performance and high resolution, with a wide frequency support range of 44.1K-192K under 16BIT mode and 44.1K-96K under 24BIT mode.
2. The DAC partly uses the fine CS8416 + CS4398, and the ear amplifier chipset adopts OP275 + TPA6120 and DAC+ digital audio decoder, which can generate a shocking music live sound.
3. CS8416+CS4398 as a common feverish chip combination, in electronic magazines and various applications have a detailed record, which indicates the performance and sound quality has been recognized by the majority of music enthusiasts. What we have done is optimize the power supply and use high precision active crystal oscillator to obtain the effect to the limit.
4. The combination of TPA6120+OP275 ear amplifier chip, which is the beautiful sound ear amplifier combination. TPA6120A2 is the current feedback type differential input high fidelity earphone amplifier IC produced by TI Company. With very low distortion, extremely high band width and conversion rate for professional audio applications, is suitable for professional high-end listening earphone amplifiers, professional audio equipment, listening and other equipment. TPA6120A2 has a dynamic range of 120dB with a conversion rate of 1300V / s and a distortion of 0.00014 THD + N. The 120dB signal-to-noise ratio (SNR) adapts to harsh requirements such as DVD audio and the Super Audio CD / CD (SACD), and can perfectly drive 30 ohms to 600 ohms of headphones.OP275 is a classic feverish amplifier chip.
5. Standard input interface: PC / USB / fiber / coaxial (switch with unplugged switch).
6. Standard output interface: 6.35mm headset / line output / standard RCA interface.
7. Output power: 90mw / 600 ohms, 180mw / 300 ohms, 450 mw / 100 ohms, 610mw / 62 ohms, 910mw / 32 ohms, 1000mwr / 16 ohms.
8. The power supply uses a voltage of: AC 100-240V.
9. Power output voltage: DC 12-1A.
Notes
1. When the volume knob is connected with the power amplifier and the active speaker, the adjusting knob is not effective. Only when the earphone is connected, the adjusting knob will work.
2. the system volume can not be adjusted when connect to the computer, because this is a digital signal. Suggest do not adjust the volume on the computer, which will lead to noise. You can adjust the volume on your power amplifier or the volume of the player.
3. Speakers and headphones should be disconnected when switching, without automatic switching.
