USB digital analog converter and Bluetooth receiver in one. The manufacturer Qudelix has developed a very special piece of technology here.
Rarely have we added such a well-rounded device to our portfolio.
The Qudelix 5K is a perfect symbiosis between good usability and technical feasibility at the highest level and at an unbeatable price-performance ratio.


The highlights of the Qudelix 5K


audio codecs

The Qudelix-5K is the world's first Bluetooth DAC/AMP that supports all current codec technologies including aptX Adaptive, LDAC, AAC, aptX HD, aptX and SBC.


QCC512x

Qualcomm's new low-power Bluetooth SoC series QCC5100 is designed for advanced Bluetooth applications. The breakthrough SoC series is designed to reduce power consumption by up to 65 percent for both voice calls and music streaming compared to the previous CSR8675 solution. It is designed to drastically reduce power consumption and offers enhanced processing capabilities.

Qudelix-5K is the world's first Bluetooth DAC/AMP designed with the QCC512x chipset. The ultra-low power consumption of the QCC512x and the most powerful DSP capability enable the Qudelix-5K to sustain high-bitrate LDAC streaming more securely and longer.


buttons and LEDs

The 5K has four buttons and two LEDs. The volume keys are equipped with a red LED, the multifunction keys with a blue LED. You can easily recognize and distinguish the left and right buttons by the LED color.


RF antenna

The highly sensitive 3-dimensional LDS antenna is printed on the bottom of the case and is located around the red LED button. The Qudelix 5K offers the best RF performance for most use cases. However, for best performance, keep this area away from metal surfaces.


PCBA

In order to improve the reliability and durability of the PCB, we filled the delicate BGA components with epoxy, but this incurs additional costs. These parts are joined twice by soldering and epoxy underfills.


battery life

Only use a standard 5V charger or PC USB. (Use NO quick charger or Apple chargers)

Any permanent damage caused by using a fast charger will void the warranty.

Battery life varies by codec, sample rate, performance profile, and output mode. The sensitivity of the connected earphones/headphones and the output volume can also increase or decrease the battery life.


USB DAC

Qudelix has tried many DACs and amplifier ICs and concluded that the ES9219C is the best option for the best performance and sound. Besides the sound quality, the main advantage of the ES9219C is that the built-in amplifier delivers a maximum output voltage of up to 2V RMS. It also supports 1V RMS option with the same sound quality to save power.

The software and the app have been developed in such a way that you have full access to all internal options of the ES9219C.

The 5K supports:


full control

You can simultaneously charge and stream the device with your PC or laptop while maintaining the Bluetooth connection with a smartphone and controlling all the functions of the Qudelix-5K via the accompanying mobile application.


headset function

Any incoming sound or call from your smartphone is automatically routed to the 5K, even if you're listening to music through the 5K USB DAC.


Suitable for almost any headphone

For highly sensitive IEMs the noise figure of the amplifier is most important. The high-sensitivity IEM is so sensitive that it converts any electrical noise or thermal drift into audible acoustic sound, typically white noise.

High impedance headphones require a more powerful amplifier. These headphones tend to have low sensitivity and are free of white noise, which is affected by the noise characteristics of the amplifier. Instead, they require more power at the amplifier output to deliver enough volume and headroom.


volume control

Qudelix 5K offers 2-way associative volume control for optimal sound quality. The fully scaled audio stream is always maintained and guaranteed over Bluetooth or USB. Either way, you can control the volume from the smartphone source volume or the 5K device volume with no leaks.
