Blue Bird U3 PLUS Hifi Portable Headphone Amplifier DAC Class A Amplifier Two OPA2604 Single Op Amp

Blue Bird U3 PLUS Hifi Portable Headphone Amplifier DAC Class A Amplifier Two OPA2604 Single Op Amp

Description:
It integrates current expansion primary amplification, current supply automatic control, power supply part optimization, earphone protection system, smart charging, and protection circuit. Support listening to music while charging.

The back is the main component layout surface, the components are more processed and the layout is more perfect. Modular design, independent layout of different functional modules.

The threshold current of Class A circuit is further improved, and 6 more heat dissipation holes are added to ensure good heat dissipation and better temperature consistency. The sound is more stable and smooth.

Optimize the layout, the signal-to-noise ratio is better than that of U3 MINI. The noise level is almost inaudible, and the layout is balanced. The heat dissipation of each module is even, ensuring a good working temperature. Working for a long time, it can also ensure that the overall temperature will not be very high, about 40°C to 50°C.

U3 PLUS:
- U3 PLUS uses 2pcs OPA604 single op amp. Each channel is sampled and amplified independently, the overall music separation is better, and the instrument positioning is more accurate
- Endurance time: 9-11 hours
- Compared with U3 MINI, U3 PLUS has better noise level control, a more reasonable layout, reduces interference between various components, has good heat dissipation, and is more stable in long-term working conditions. Compared with U3 MINI, U3 PLUS mainly improves the power supply part, with larger capacitance. With better energy storage, greater thrust, better control over sound, better thrust, stronger control over the sound unit of your headset. Therefore, in large dynamics, the sound is not blurred, the high-frequency sound has no glitches, and the overall sound is clear and transparent
- Use special socket for Foxconn laptop, can be plugged and unplugged tens of thousands of times without deformation
- U3 PLUS audio coupling input adds 2pcs laser version audio coupling capacitor for WIMA, which has a better improvement on the overall tone, and the softness of the sound is significantly improved

Features:
- Accessories: 3.5 recording cable, 2 straps
- Battery capacity 2200MA
- The body is made of all-aluminum, grade 2 oxidation treatment, laser screen printing, permanent color
