Description :
- Low Distortion, Dual CS43131 DAC Chips : Each of the two CS43131 DAC chips used by Link2 Bal has a higher resolution and greater decoding capability. You don’t have to worry about background noise when using most earphones because they have SNRs up to 127dB to guarantee a clear and clean sound. To further lessen distortion and output floor noise, the decoding chip, amp, and digital reception chip are all powered individually.
- Release The Potential of Earphones With 270mW High Power : With a conversion efficiency of more than 85%, the Tl LM27762 chip, utilized by Link2 Bal to supply ultra-low noise electricity, powers the amp circuit with a current output of up to 250 mA, enabling high precision and high output current drive capabilities to assure dynamic output and recover hearing.
- High Resolution & 3.5mm/4.4mm Dual Output : LINK2 BAL supports up to PCM32bit/384kHz and native DSD256, maximizing the power of your dynamic driver headphones whereas ordinary mobile phones can only decode audio at 16bit/48kHz. With good headphones, it will shine even more. Link2 Bal includes a 4.4 balanced output and a 3.5 unbalanced output, so you can use it with a variety of headphones without the use of adapters.
- High-end Workmanship and Quality : Link2 Bal uses 2.5D double-sided glass and a CNC technology to create a seamless, elegant body with no seams or screws visible on the surface. The body’s surrounding surface is sandblasted, pigmented, and has been oxidized; it has a straightforward appearance and a delicate feel. The Type-c wire port is snugly seated and prevents dust from entering the connection.
- Compact and Lightweight for Any Occasion : Link2 Bal just weighs 28g, making it simple to carry and use in any situation. You may carry it wherever you go in your pocket because it is as small as a USB drive. You may play on the Switch with greater sound quality because it is also compatible with popular multi-platform or scenario applications for computers, tablets, iPhones, and Android phones.
