HUM Pervasion 8GB WM8741 28nm A9 WiFi Bluetooth Dual-Core HiFi Music Player

Description

HUM Pervasion is designed for the music lovers , which let the enjoyment and indulgence pervade .

Wolfson flagship audio codes WM8741

WM8741 is widely used in high performance home audio system, while Pervasion is the first portable music player using one.

Power supply

WM8741 relies on 5V and 3.3V power supply respectively for the operation of analog and digital signal processing. The performance of step-up and LDO IC is of great importance as they are directly correlated to sound quality.

The 5V step-up efficiency of Pervasion reaches a high standard of 95%, top notch among the industry, while the 3.3V LDO power supply control noise to the lowest level possible .

Low-pass filter(LPF)

In line with KEMET’s high frequency capacitor as low-pass filter, TI’s op-amp LME49720 guarantees low noise and low noise and low distortion for lineout signals.

Analog & digital dual vol. control

Due to noise generated from DAC’s signal processing, genuine ALPS potentiometer is implemented to limit noise and to enhance signal to noise ratio (SNR),together with WM8741’s digital vol. control good channel balance at low volume will be ensured .

High voltage amplifying stage

Pervasion has implemented a high efficiency yet stable power supply structure, providing+/-8V voltage, an excellent working environment for LME49720 and TL072.promising good driving power on the go without an extra amp.

Excellent energy supply system

Pervasion has taken another special approach, aside from the most important audio circuitry, high stability gains ICs and electronics parts. From WIFI modules, DC-DC for DDR to LED driver are carefully picked, all of these formed a perfect power supply structure for the player.

0.5ppm TXCO crystal oscillator

Environment factor and heating up of the player will affect stability of the oscillator, a low phase noise and jitter, high accuracy 0.5ppm temperature compensated crystal oscillator is embedded to compensate such error, ensuring high accuracy of signal.

Masell Li-ion battery

Clean and efficient power source is the key to good signal processing  , the masell li-ion battery used is highly durable and consistent in voltage, capacity and impedance, through nanotechnology si-based anode, the battery capacity is 20% higher than common ones , spot test result has revealed its stunning low internal resistance~40-50mΩ.with the 20awg*30 pure cooper battery connection wire, the resistance after hooking up and heat produced during high output can be greatly reduced, facilitating a great foundation to efficient, stable and safe power supply
