Shanling / UA4 Gold 4.4mm Balanced Portable DAC/AMP

Equipped with the ESS ES9069Q chip, the UA4 provides excellent sound quality with a maximum S/N ratio of 120dB, 768kHz/32bit, and DSD512 compatibility. The dual operational amplifier RT6863 achieves high output (227mW@32Ω), allowing you to experience deep bass and dynamic sound. Compact in size and compatible with gaming DAC mode and MQA, it can be used in a wide range of applications.

■Equipped with ESS ES9069Q High level sound performance
・UA4 adopts the ES9069Q flagship chip in a compact DAC/AMP housing, which has a maximum S/N ratio of 120dB and supports 768kHz/32bit|DSD512. By adopting the ES9069Q, we have achieved stronger D/A performance, lower power consumption control, and improved smoothness, resulting in a sound quality that is more natural and more realistic than previous models.

S/N ratio: 120dB
PCM: 768kHz/32bit
DSD: DSD512

■Dual adoption of full power independent operational amplifier “RT6863”
・UA4 is equipped with a newly designed analog circuit that uses two independent operational amplifiers ""RT6863"". This circuit greatly reduces distortion and boasts a high output of 227mW @32Ω and an excellent dynamic range. Compact and highly portable, it supports a high output music experience. 227mW @32Ω (at 4.4mm balanced output)

■Equipped with 6 small size Hi-Fi quality polymer tantalum capacitors
- The analog circuit section is equipped with six 100uF KEMET polymer tantalum capacitors, which we arrived at in our search for a more powerful and deep bass range. By creating a deeper, thicker, more powerful, and more stable low-range texture as a base, we have made it possible to fully grasp the rich, undulating low range and the cohesiveness and elasticity of the sound.

■3.5mm + 4.4mm compatible dual interface
・UA4 is equipped with a dual interface of 3.5 single-ended + 4.4 balanced connectors, supporting a wide range of connectivity and a high output of up to 227mW@32Ω with 4.4mm balanced output. With stronger driving force, it can be adapted to connect with various devices and greatly improve your music experience with just one unit.

maximum output
3.5mm: 137mW @32Ω
4.4mm: 227mW @32Ω

■High performance compact machine that follows new technology
・UA4 adopts newly developed technology that optimizes power consumption, reducing overall power consumption of UA4 and improving performance when connected. Power can be adaptively adjusted depending on the operating status during playback, the sampling rate of the music being played, etc., and power can be effectively reduced. Compared to conventional models, it consumes far less power, making it possible to listen for long periods of time.

■Low noise floor pure sound design
・The UA4 adopts the noise control technology that SHANLING has inherited in its DAC/AMP, and is equipped with an LDO regulator with excellent low noise performance, resulting in extremely excellent noise control and pure sound. The Hi-Fi design provides an immersive listening experience with excellent layer fidelity without fear of noise interference.

■Free cable selection Adopts replaceable Type-C connector
・UA4 comes standard with a cable that uses 18-core high-purity oxygen-free copper wire, and this matchup provides pure signal transmission and rich sound quality. Adopting a Type-C connector that supports replaceable cables, it is widely compatible with iOS / Android / PC devices, ensuring multi-device connectivity and customizability by users.

■UAC1.0 compatible Gaming DAC Mode
・UA4 supports ""UAC1.0"" and can be connected as a gaming DAC by holding down the center key of the mechanical button and connecting to a gaming console.
The UA4, which operates with ""UAC 1.0"", operates as a USB-DAC/AMP for game consoles such as home consoles, allowing you to play games with high-quality sound and enjoy them more vividly with an immersive and highly realistic feeling.

■APP personalization with EddictPlayer
・UA4 allows you to change settings such as DAC volume, gain, digital filter, etc. to your favorite settings using the dedicated application ""EddictPlayer"" and save your favorite settings.
*EddictPlayer APP is an Android-only application.

■Hi-Res / MQA support MQA 16X compatible
・UA4 supports MQA 16X and supports MQA decoding that can be expanded up to 16X.
It has been certified as ""High Resolution Audio"" by the Japan Audio Association, and its excellent sound quality reproduces rich details that are full of reality.

■Equipped with mechanical buttons to ensure smooth operability
・UA4 uses three mechanical buttons for speedy play/stop/volume control.
You can also access settings such as gain and digital filter, and this button also ensures customization that does not require an APP.
