Full-scale implementation of AKM's DAC chip
The Lotoo Paw S2 brings out the full performance of the legendary AKM4377 DAC chip. The PAW S2 provides a clean, high-resolution output signal with ultra-low distortion and a high signal-to-noise ratio to maximize the performance of the connected earphones/headphones, allowing you to listen to your favorite music in a dark, noise-free environment with vivid detail.
High-end DAP architecture
Lotoo designed the Paw S2 as if it were designing a high-end digital audio player system: the Paw S2 features a Blackfin DSP and an advanced 2x8 layer HDI PCB design. The analog board uses low-noise, low-temperature drift metal film resistors with millimeter precision.
High-precision phase-locked loop
The Lotoo Paw S2 uses the AK8142, a programmable clock generator IC with an integrated fractional-N PLL. The company had previously implemented this clock in high-end digital audio players. This clock is a high-precision jitter clock that effectively reduces jitter in USB and SRC interfaces, ensuring high-end performance of this device.
Powerful output with a standalone headphone amplifier
The Lotoo Paw S2 features a stand-alone headphone amplifier that delivers a powerful output of up to 150mW @ 32Ω on the 4.4mm balanced headphone output jack.The Paw S2 provides a load of up to 125mW @ 32Ω on the 3.5mm single-ended headphone output jack. The Paw S2 has two gain levels, high gain and low gain. The Paw S2 has two gain levels, high gain and low gain, and the "fn" key on the side allows you to easily switch between the two gain modes.
Media Control Key
Just below the "fn" key on the side, the Paw S2 has three media control keys: two keys are used for volume control and menu operations, while the middle key is used for playing/pausing music.
Built-in studio-quality PMEQ/ATE presets
Lotoo's PMEQ and ATE equalizer presets were among the best in the Paw S1, and the Lotoo Paw S2 adds more PMEQ and ATE presets. ACG-1 for PMEQ and Vinyl LP and Cassette presets for ATE.
New OTG cable
Lotoo Paw S2 is pleased to announce the release of a new OTG cable in two different lengths (65mm and 800mm). This product is a high-purity cable made of pure OFC copper combined with copper shield net and aluminum foil. In addition, the black TPE shield makes the cable both flexible and strong.
