Qudelix - 5K Bluetooth USB DAC/Amp

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.

DUAL ES9219 DAC CHIP: The ES9219 Upgraded 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 Hyper Stream II modulator. This is the same architecture that is used in the world's finest audiophile equipment.

HIGH QUALITY BLUETOOTH CODEC: 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: 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 4VRMS: 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.

FREE SHIPPING ON ALL PREPAID ORDERS

We usually ship orders on same day if ordered before 2 pm or within 24 hours if ordered later (except on holidays/sunday, where processing times may be higher) from one of our domestic warehouses based out of Delhi. It normally takes around 1 to 5 business days for delivery. We use premium service partners such as Blue dart, DTDC and Delivery for faster and reliable service. A tracking number will be provided upon shipment.

In very rare cases when order is not received after 10 business days of shipment (extended by number of days when the govt. Restricts movement of goods due to factors such as coronavirus pandemic), please contact us and we will provide you a refund.
