U606 Pro Mini Portable Headphone Amplifier MC33078P Op Amp No Low Noise HiFi Audio Amplifier
Functions:
- Low battery indicator function: The power indicator light flashes for 0.5S when the battery is low.
- Delay the headphone output by 2 seconds when powering on (to ensure stable power supply in the circuit before turning on the headphone output, to avoid damaging the headphones instantly when powered on).
- Equipped with headphone protection, the headphone protection works when there is a circuit fault, cutting off the headphone output and the power indicator light flashes 0.2S - Fault Reminder.
- Fully symmetrical power amplifier power supply circuit: capable of providing high current positive and negative power supply, improving the bandwidth and dynamic response of signal amplification, supporting simultaneous audio input and USB charging for computers and other devices.
- The new solution further enhances power efficiency (battery life: >9 hours, generally 9-12 hours, depending on different usage situations)
- Adopting an IC socket and replaceable operational amplifier design (supporting standard DIP-8 dual operational amplifiers), it has high playability (and supports ceramic packaged operational amplifiers).
Features:
- The sound is sweet, and with this headphone amplifier, you can feel a significant increase in sound field, better resolution, and highlight better vocals and layering.
- When the volume knob is turned to the maximum (when silent), the background noise is basically not turned on.
- Small in size and easy to carry. The weight is only 120g.
- Ultra thin laser shell, simple and clear, has a strong sense of technology.
- Standard MICRO USB 5V power supply: Connect the charger, the red light will turn on, and after about 3.5 hours of charging, the red light will turn off. It can play while charging, and the machine has an overcharge and discharge protection function. When fully charged, it will automatically stop charging.
