2. Produktet er slutview og nøglefunktioner
The DX5II is a new generation fully balanced DAC and headphone amplifier combo, offering significant upgrades and advanced functionalities for an enhanced audio experience.
Nøglefunktioner:
- Dual ES9039Q2M DAC Chips: Each channel utilizes an independent ESS ES9039Q2M DAC chip for lower crosstalk, improved imaging, 133dB SNR, 133dB dynamic range, and distortion as low as 0.00006%.
- X-Hybrid Headphone Amplifier kredsløb: Features an original triple-stage hybrid amp circuit (discrete input, op-amp gain, discrete output) for high efficiency, improved thermals, and precise delivery. Power output peaks at 7600mW x2 into 16Ω.
- Wide Headphone Compatibility: Equipped with 6.35mm single-ended, 4.4mm balanced, and 4-pin XLR headphone jacks, suitable for low-sensitivity headphones to high-sensitive IEMs with a low noise floor of 1.8uVrms.
- 10-Band High-Precision PEQ: Desktop software allows tweaking 10 independent frequency bands (frequency, gain, Q-factor adjustment). Multiple profiles can be saved, and EQ can be applied independently to speakers and headphones.
- LDAC Wireless Connectivity: Equipped with QCC5125 chip, supporting Bluetooth 5.1 and up to 96kHz/24bit. Fully supports LDAC, aptX-Adaptive, aptX HD, AAC, and SBC audio encodings for high-quality wireless audio.

5. Fejlfinding
If you encounter any issues with your DX5II, refer to the following common problems and solutions:
- Ingen lyd: Check power supply, input selection, cable connections, and upstream devices.
- H/M/L blinks, others are off (Firmware exception): Unplug and re-plug the power cable, then flash the firmware again.
- HML and H/L blinks alternately (Input voltage is high/low): Brug den medfølgende strømadapter.
- HML and M blinks alternately (Positive and negative voltage anomalies): Check power supply, disconnect other devices, and reboot.
- Blinks only the current gain LED (Headphone amplifier circuit outputs abnormal DC voltage): Change the song or turn down the volume.
