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.

QX-Over Earphones
QX-Over
QX-Over is an active digital crossover with Qudelix's proprietary DSP technology. Qudelix-5K automatically detects QX-Over Earphones, processes the stereo input, and outputs Stereo Low and High band independently to earphones units through 4-channel DAC/AMP.
Multi-Driver vs. Single-Driver
Earphones and Speakers can be designed with a single speaker unit or multiple speaker units. It depends on, but practically, a si
