What is Bluetooth DAC/AMP?
Bluetooth DAC/AMP receives the digital audio over the Bluetooth link and performs Decoding, D/A Conversion, and Amplification with its hardware. Many use USB DAC for upgrading PC or Laptop Sound Quality. For smartphones, Bluetooth DAC can be the best option to upgrade Sound Quality. Although Bluetooth Audio Codecs are all lossy codecs, SONY LDAC, aptX-HD, and AAC provide good enough perceptual audio performance, enabling the built-in DAC/AMP reproduce the best Sound Quality.
Qualcomm QCC5124 - The new Qualcomm Low Power Bluetooth SoC QCC5100 series is designed for advanced Bluetooth application. The breakthrough SoC series is engineered to reduce power consumption by up to 65 percent for both voice calls and music streaming, compared to previous CSR8675 solution. It is designed to reduce power consumption dramatically and offers enhanced processing capabilities. Qudelix-5K is the world 1st Bluetooth DAC/AMP designed with QCC512x chipset. QCC512x's ultra-low power consumption and the most powerful DSP capability enable Qudelix-5K to maintain high bitrate Bluetooth streaming more secure and for a longer time.
Embedded Pro-Grade Equalizer - 5K is the only Bluetooth DAC/AMP, which provides a pro-grade 64-bit double-precision parametric equalizer for every input source. It processes every incoming source audio from everywhere: Youtube, Apple Music, Spotify, iOS, Android, PC, Bluetooth(all Codecs), and USB. It provides accurate and precise filtering performance, keeping original sound quality and resolution.
Qudelix is an audio system engineering company. We deliver a portable and affordable high-end audio solution for everyone. Based on our R & D team's highly extensive background and experience, we design and implement the cost-effective high-end audio system. System-on-Chip (SoC) is one of the most important keys to the best digital audio system. We always keep up with the latest semiconductor technology and build the application with optimized software and hardware. We are an Official Partner of Sony's LDAC, and provide our LDAC solution to the other set makers.

QCC5124 Quad-Core Processors
QCC5124 architecture is engineered for high performance with low power consumption. Power consumption can be reduced by up to 65 percent compared to our previous technology for both voice calls and music streaming, and devices are optimized to support longer audio playback in virtually all operating modes. |
ES9219 x 2
The ES9219 SABRE HiFi SoC delivers audiophile-grade sound quality and output power, allowing the ES9219 to drive the most demanding headsets and provide a real line-level output to match professional audio equipment. The heart of the ES9219 ESS's award-winning SABRE DAC technology, with a HyperStream II modulator. This is the same architecture that is used in the world's finest audiophile equipment. |
High-quality Bluetooth codecs
5K supports the latest high-quality audio codecs, including aptX Adaptive, SONY LDAC, and AAC. Android 8.0 or higher supports LDAC by default. *iOS works with Bluetooth AAC 260kbps. |
|
2.5mm BALANCED 4VRMS
Balanced: Always Better Within any given audio system, the Balanced provides higher output power, better linearity, and lower noise than the Unbalanced. To the 2.5mm output, 5K works with Dual ES9219 DAC/AMP. *You will need to replace the existing 3.5mm UNBAL cable with 2.5mm BAL cable. |
3.5mm UNBALANCED 2VRMS
To the 3.5mm output, 5K works with Single ES9219 DAC/AMP. The ES9219 SABRE HiFi SoC delivers audiophile-grade sound quality and 2VRMS output power, allowing the ES9219 to drive the most demanding headsets and provide a real line-level output to match professional audio equipment. |
Automatic Battery Care
5K manages the battery for maximum life cycle, not for the time. Furthermore, 5K draws its system power directly from USB when working as a USB DAC. In other words, 5K does NOT draw any power from the battery when charging. It helps keep the battery life longer, and it ensures the same battery charging time even while streaming audio. |

10-Band Pro-Grade Equalizer
The embedded pro-grade equalizer is a vital benefit of 5K DAC/AMP over other similar products. It processes every incoming source audio from everywhere: Youtube, Apple Music, Spotify, iOS, Android, PC, Bluetooth(all Codecs), and USB. For more degree of freedom, 5K DAC/AMP supports parametric EQ in addition to graphical EQ. The embedded DSP cores perform double-precision 64-bit EQ processing, providing accurate and precise frequency response. |
2-Way Associative Absolute Volume
5K always delivers the optimal Sound Quality, whatever source or device volume levels are. Any source volume level or device volume level will eventually control the 5K built-in Hybrid Volume System, keeping the source audio's original bit-resolution. No need to keep the smartphone volume or PC USB volume at the maximum anymore for the optimal Sound Quality. Adjust volume whatever comfortable way you like it. |
iOS/Android App
5K Mobile App enables the user to access every detail; Battery history, charger status, volume, DAC operating profile, DAC LPF filter, Equalizer, USB DAC sample rate, microphone gain, Bluetooth codecs. *5K is the only Bluetooth device that displays real-time LDAC bitrate. |

Silicon MEMS Oscillator
The built-in MEMS audio clock helps ES9219 D/A Conversion perform its best. Silicon is inherently more reliable than quartz. MEMS OSC also provides 3000 times better Vibration Robustness than quartz OSC. |
3-D LDS Antenna
5K delivers the optimal RF performance with high Sensitivity 3-dimensional LDS(Laser Direct Structuring) Antenna. The antenna is printed on the bottom case around the Red LED button. |
Small & Lightweight
The smallest form factor: 52.8(H) x 26.7(W) x 15.6(D) mm (including Clip) Weight: 25g USB-C-to-C, C-to-A Cable included |
