High-End DAP Architecture
Lotoo has designed the Paw S2 like they design 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.

Highly-Accurate Phase-Locked Loop
Lotoo Paw S2 uses AK8142, a programmable clock generator IC with an integrated fractional N PLL. They had previously implemented the same clock in their high-end digital audio players. It is a highly accurate jitter clock that effectively reduces USB and SRC interface jitter ensuring a high-end performance with the device.

Powerful Output With Standalone Headphone Amplifier
Lotoo Paw S2 features a standalone headphone amplifier that provides a powerful output of up to 150mW @ 32Ω through the 4.4mm balanced headphone output. With the 3.5mm single-ended headphone output port, the Paw S2 outputs up to 125mW @ 32Ω of load. The Paw S2 has extra output power in comparison to the former model. The Paw S2 has two gain levels, high-gain and low-gain. Users can easily switch between the two gain modes by using the “fn” key on the side.

Media Control Keys
Right below the “fn” key on the side, Paw S2 also has three media control keys. While two are just for volume and menu navigation, the center key can be used to play/pause the music playback.

Built-In Studio Quality PMEQ/ATE Presets
