3.5mm + 4.4mm balanced dual headphone output

Link2 Bal has 4.4mm balanced output and 3.5mm unbalanced output, no need for adapters even if you have a variety of headphones.

Independent amp circuit, bigger output power

Using the TI LM27762 chip with a conversion efficiency of more than 85%, it provides ultra-low noise electricity, and the current output of up to 250mA is used to power the amp circuit, thus providing high precision and large output current drive capability to ensure dynamic output and restore the sense of hearing.

Low noise, low distortion

Link2 Bal uses two CS43131 as DAC chips, the chip S/N is130dB, and the unit S/N is 127dB to ensure a clean and clear sound, rejecting noise and interference, and the decoding chip, amp, and digital receiving chip are all powered separately to further reduce Distortion and noise floor of the output.

High SNR

The SNR up to 127dB, with most earphones, you don’t have to worry about the existence of background noise.

*The earphone sensitivity is expressed in dB/mW.

High resolution, more brilliant with high-quality headphones

*Ordinary mobile phones can only decode 16Bit/48kHz audio.

*LINK2 BAL supports up to PCM 32Bit/384kHz and native DSD256.

Dual DAC chips, true balanced architecture

Link2 Bal adopts two DAC chips, which each channel has better decoding performance and high resolution, which greatly improves the sense of hearing. The true balance circuit architecture.
