Shanling UP4 Dual ES9218P Portable DAC/AMP
>Compact, affordable, yet high-performance, the Shanling UP4 is a DAC combo and portable symmetrical headset amplifier with Bluetooth 5.0 connectivity. It will accompany your smartphone or DAP to reveal its full potential, wherever you are.
>Ultimate Connectivity - The UP4's high-performance Bluetooth 5.0 connectivity is compatible with the standard AAC and SBC codecs, as well as the high-definition codecs aptX, aptX HD, aptX LL, HWA LHDC and LDAC. These last codecs enable high-quality audio transmission that can match or exceed CD quality in wireless applications. The UP4 benefits from the dual certification of Hi-Res Audio and Hi-Res Audio Wireless.
On its front panel, an LED indicator displays in real time the transmission codec used.

>ES9218P Dual DAC / Amplifier - At the heart of the Shanling UP4 are two ESS Sabre ES9218P chips. The latter, which are responsible for both digital/analog conversion and signal amplification, provide a clear and detailed reproduction, while developing considerable power with a low output impedance. One chip is used for each channel. In addition, the UP4 can also be used with a computer in USB DAC mode. Once connected via its USB-C connector, the UP4 becomes a very good sound card.
>Balanced Output - Connect your headphones or earphones to the balanced 2.5mm jack output to enjoy the full potential of the two ES9218P chips. This balanced output provides more power, more detailed sound reproduction, and better channel separation.
>Gain Control and Digital Filters - The UP4 allows you to simply select a gain level (Low, High and Dual DAC/Boost) and one of four digital filters available. It is thus capable of adapting to your listening and your equipment in an instant.
>Dual DAC Mode - Dual DAC mode allows the UP4 to use its two ES9218P chips to get more output power, even with standard headphones and on its unbalanced 3.5mm jack output.
