Bring Home The Power Of AKM DAC Chip:-

AKM Technologies is a worldwide renowned brand, mostly known for its high-performing DAC chips. Lotoo has equipped the Paw S2 with AKM’s trusted AK4377 DAC chip. It decodes high-resolution 32-Bit/384kHz PCM as well as DSD128 natively with ultra-low distortion and high SNR ratings ensuring a clean, noise-free sound output.

MQA Decoding Support:-

Lotoo Paw S2 supports 4x MQA signal decoding. MQA(Master Quality Authenticated) is the latest standard for high-resolution audio recordings. Paw S2 has received the required certification, it decodes MQA signals by unfolding them up to 4 layers. Be prepared to get the best sound quality experience with your smartphone and Paw S2.

Based on High-End DAP Architecture:-

Lotoo has designed the Paw S2 similar to their high-end digital audio player systems. The Paw S2 features Blackfin DSP, advanced 2×8 layers of HDI PCB design. The analog board here employs a low-noise, low-temperature drift metal film resistor of millesimal accuracy.

High-End Phase Locked Loop Architecture:-

Lotoo has implemented AK8142, a programmable clock generator IC with an integrated highly-accurate phase locked loop. It is a highly accurate jitter clock that effectively reduces USB and SRC interface jitter ensuring a high-end performance with the device.
