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.
Built-In Studio Quality PMEQ/ATE Presets:-
Lotoo’s PMEQ and ATE Equaliser presets were some of the best things with the Paw S1. The Lotoo Paw S2 brings more additions to the PMEQ and ATE presets, The PMEQ has ACG-1, while ATE has added Vinyl LP and Cassette presets.
New Longer OTG Cables:-
Lotoo has included new OTG cables with the Paw S2. They are available in two different lengths, 65mm and 800mm, so that users can use as per their requirement.
