UB01 User Manual

Product Introduction

This product is an all-in-one decoding earphone amplifier that receives input via

HIFI Bluetooth/independent USB chip and outputs PO/LO through the earphone

port.

I. LDAC Bluetooth ensures lossless sound quality

1-1.LDAC Bluetooth Codec Technology: This earphone amplifier is equipped with

Sony's top-tier HIFI LDAC Bluetooth codec technology. This technology significantly

enhances the audio quality of Bluetooth wireless transmission, allowing for up to

three times the data transmission rate of ordinary Bluetooth technology, achieving

Hi-Res level audio. LDAC works like an expanded bandwidth, significantly improving

the sound quality of Bluetooth wireless audio, providing users with a more delicate

and rich musical experience.

1-2. Independent USB Chip for Input Reception: In addition to Bluetooth connectivity,

this earphone amplifier also features an independent USB chip for input reception,

supporting high-speed and lossless audio data transmission. This ensures that every

bit of musical detail is perfectly preserved, allowing users to enjoy high-quality audio

even when using a USB connection.

II. Philips decoding triple DAC chip restores the charm of music

2-2. Philips Charm Decoding Chip: The smooth timbre and excellent musical

expression of the Philips decoding chip have won the recognition of numerous audio

enthusiasts. The UB01 features three Philips charm decoding chips, renowned for

their powerful mid-frequency appeal, making it especially suitable for listening to old

songs, slow songs, and vocals with exceptional clarity. It unlocks the deeply hidden

emotions and layers within music, restoring the original charm and nuances of the

music. Every listening session is a reinterpretation of the art of sound, inviting your

ears to indulge in an unprecedented musical feast.

III. High Voltage Operational Amplifier

3-1. Texas Instruments High-Voltage Audio Amplifier: Equipped with the Texas

Instruments high-voltage audio amplifier, renowned for its low noise and low

distortion, this amplifier further enhances audio quality, delivering purer and more

natural sound.

3-2. PGA2310 High-Voltage High-Fidelity Volume Control Chip: Breaking free from

the constraints of mobile phone volume adjustment, we have specially incorporated

the Texas Instruments PGA2310 high-voltage high-fidelity volume control chip. This

chip not only improves the fine precision of volume adjustment but also avoids

potential audio quality loss caused by digital volume control on mobile phones

through its analog volume control method. It is recommended to set the volume of

your mobile phone or computer to the maximum and then adjust the volume using

the UB01's volume knob for further enhanced audio quality.

3-3. Dedicated Headphone Amplifier Chip for Audiophile Headphones: Equipped with

the same dedicated headphone amplifier chip as Sony's premium headphones priced

at 60,000, this chip is specifically designed for over-ear headphones. It fully unleashes

the potential of your headphones, delivering richer and more powerful sound quality.

IV. Power Supply and Protection Mechanism Guarantee

4-1. Intelligent Power Supply System: For headphones that are difficult to drive, if you

feel the loudness is not enough and want to increase the driving force, simply

\"double-click\" the button after turning on the device to activate the analog power

supply with a positive and negative voltage difference of approximately 28V, similar

to that of desktop audiophile equipment. This design enhances audio quality.

4-2. Multiple Protection Mechanisms: Equipped with multiple protection mechanisms

including DC protection, power supply abnormality protection, software low-voltage

protection, and repeated secondary hardware low-voltage protection, it

comprehensively ensures the safe and stable operation of the earphone amplifier and

its internal hardware, preventing audio quality degradation due to power supply

issues or hardware failures.

4-3. Long-lasting Battery Life: Featuring a 7600mAh (3800mAh x 2) high-capacity

battery and supporting TYPE-C fast charging, it is easily compatible with mobile

phone and computer chargers. With just 3 hours of charging, you can enjoy up to

15-20 hours of continuous playback. Whether on a long journey or for daily

commuting, music will accompany you without interruption.

4-4. Freedom in One Device: Supporting Bluetooth/USB dual-mode input, it is
