The Link2 Bal has a 4.4mm balanced output and a 3.5mm unbalanced output. With an independent amp circuit, 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. Compared with the previous generation Link 2, the most direct change of Link2 Bal is the addition of a balanced port. Besides, when it comes to the output power Xduoo is most proud of, Link2 Bal has reached a single-ended 125mW@32Ω and balanced with an amazing level of 270mW@32Ω.
