Product Description

TPA6120A2 Amplifier The TPA6120A2 is a very high fidelity headphone amplifier. it’s current-feedback AB amplifier architecture delivers high bandwidth, extremely low noise, and up to 128dB of dynamic range. OPA2134 HIFI Operational Amplifier The OPA2134 is ultra-low distortion, low-noise operational amplifiers fully specified for audio applications. Aluminum body A highly automated machining center needs more than 46 processes to make a NX3’s aluminum case. Matte surface We use same surface blasting process as MACBOOK air to get a fine matte effect. All characters was engraved on the surface by laser. Easy to use We design a suitable size for operating the knob and make 2 notch on the side of panel to fit your finger. Toggle switch of gain & bass control are easier to operate and read. Selectable Mega Bass NX3 boosts only mega bass effect to you while bass on. And if bass off, mega bass circuit will be fully cut off, it will not bring you extra distortion and noise. High-quality components NX3 has a good amplifier chip, better components will upgrade it’s performance to be better. That’s why we use ALPS potentiometer, WIMA capacitance, and also gilded the headphone jack, the switch and the PCB. Long playback time Fully charge<4h Playback>25h 30 min charge 5h playback 2400mAh Lithium Ion battery provide >25 hour playback time which needs less than 4 hour to be fully charge. 30 min charge could provide 5 hour playback time if low power. Low battery reminder When the battery is low, NX3’s power LED will turn red to remind you to charge it as soon as possible. After the power LED turns red, the remaining power can provide about half an hour playback time. Adaptive Charging NX3 automatic fits 0.5A current from PC’s USB port and 1A current from a USB charger. It takes less than 4 hour to fully charge NX3 at 1A charge current. Note: For a USB charger which output >1A cuttent, NX3 will use 1A current to charge. 30 min charge for 300 min playback When the battery is low, NX3’s power LED will turn red to remind you to charge it as soon as possible. After the power LED turns red, the remaining power can provide about half an hour playback time. Certification NX3 has CE, ROHS and FCC certification.
