• Q

  I've connected all the cables, so why is there no sound output?

  A

  Check if the device is powered on, if the wiring is correct, and if it has been switched to the appropriate input mode.

  Check if the volume is too low. If so, turn the encoder knob to the right or use the remote control to increase the volume.

  If both of the above are normal, check if the audio input device is paused, muted, or at a very low volume.

• Q

  Why do drivers sometimes become unrecognizable on a computer after being installed for a period of time?

  A

  Changes or updates to computer systems, software/hardware, or antivirus software can sometimes cause drivers to be lost. You can try reinstalling the drivers and see if that helps.
• Q

  Why can't I find Bluetooth devices?

  A

  Short press the encoder knob to enter the menu, select the input mode or the "SELECT" button on the remote control to switch to Bluetooth input mode (the "BT" character will flash), then turn on Bluetooth on your phone, search for "SUCA AUDIO DAC-Q11 PRO", and click to connect and pair.
• Q

  Why is there noticeable background noise/current hum, playback stuttering, or even disconnection when using Bluetooth mode?

  A

  Check if the machine's antenna is installed correctly and if the Bluetooth connection distance is too far (greater than 15 meters).

  Are there any obstructions or interference (such as common WiFi routers/cordless phones/FM radios, which may cause interference because these devices may be on the same frequency band as Bluetooth)? In addition, inductive loads such as electric fans/refrigerators/air conditioners in the home can also cause some interference.

• Q

  USB connection to phone not working, is driver needed?

  A

  The phone connection is driverless. You should confirm that both the phone and the cable support OTG function. Some phones require you to enable the OTG option and set the output device in the settings.
• Q

  Why can my computer only display 24-bit/192kHz from my DAC decoder?

  A

  Because some computer systems can only display up to 192kHz, but in reality, FOOBAR ASIO can play DSD512/PCM 768kHz from source.
• Q

  Is the playback volume of DSD lower than that of PCM?

  A

  This is normal; DSD is 3dB quieter than PCM.
• Q

  My computer can recognize the USB DAC, but the driver won't install?

  A

  This is usually because the computer system lacks a digital signature patch or the USB DAC has been disabled by the antivirus software. Please disable your antivirus software and reinstall it.
• Q

  Why is there no sound from the fiber optic input?

  A

  Confirm the connected device and whether the fiber optic cable is for output or input (e.g., connecting to a TV with fiber optic output). You will need to set the output mode and sampling rate on the TV (there is usually a PCM output mode option).
• Q

  There is static when playing DSD music, and the music volume is very low.

  A

  Please adjust your computer's system volume to 100: Click the speaker icon in the lower right corner of your computer - Playback devices - double-click the USB device, and adjust the volume to 100.
• Q

  Do Apple computers need drivers installed?

  A

  No, the macOS system is driverless and can be used directly. The macOS system supports up to DOP256.
• Q

  Why is it that sometimes the VU meter swings very small at high volumes, but very large at low volumes?

  A

  The device has a built-in VU meter gain automatic adjustment device. When the signal is low, the system automatically switches to high gain, and when the signal is high, the system automatically switches to low gain to ensure that the VU meter has sufficient swing at all volume levels.
