A: After scanning songs from a USB drive or hard drive, the default view is the song list. Tap the second icon in the upper-right corner, the music-note icon, to switch to folder display mode. Tap it again to switch back to song list mode. You can switch between the two display modes at any time.

A: By default, the username is root and the password is root.

A: Recommended order: OTG > SMB > HTTP.

The differences are as follows:

1. OTG transfer (fastest and most stable): connect the phone and computer directly with a USB cable. This provides the fastest transfer speed, up to USB 3.0 speed, with the lowest latency. It is suitable for transferring large batches of files. Operation steps will be added later.
2. SMB connection (most recommended on a local network): access device files through SMB while both devices are on the same LAN. Transfer speed can exceed 100 MB/s, making it suitable for medium and large files without a USB cable. Operation steps will be added later.
3. HTTP connection (local network use): also requires both devices to be on the same LAN. It is easy to configure through a browser or HTTP tool, but is usually slower than SMB.

Summary: for daily use, SMB is recommended because it is fast enough and does not require a cable. For large batch transfers, use direct OTG. For remote access scenarios, use HTTP.

A: The device cannot directly access an external-network NAS. If you need to access external resources, consider using WebDAV or HTTP access instead.

A: Yes. In File -> Scan, tap the second icon in the upper-right corner to switch. When it changes to the music-note icon, songs can be displayed by folder.

A: Files beginning with ._ are usually hidden files generated by macOS. They are not real audio files and may cause recognition or playback issues. Delete all hidden files beginning with ._ from the USB drive on your computer, then scan and play again.

A: First check the device system version and upgrade to the latest firmware. If the issue remains after upgrading, contact after-sales support to confirm whether it is a known hardware compatibility limitation.

A: Check the network environment first. If you are playing over Wi-Fi, test with a wired network or restart the router. If you are playing local files, close unnecessary background apps and check whether the M.2 SSD or USB drive is reading reliably.

A: This is normal and is not a device fault.

DSD512 is a high-bitrate, high-load audio format. Playback requires higher decoding and data processing performance. To ensure stable playback, smooth operation, and sound quality, the device prioritizes audio playback itself when playing DSD512 tracks. Therefore, the spectrum effect and VU meter display are automatically disabled to reduce extra system load.

A: Baidu Netdisk online playback and loading speed depend on account membership and network conditions. Please confirm whether your Baidu Netdisk account has an active membership, and use a wired network whenever possible.

A: CD-ripped files are usually saved under: File -> Storage -> Internal shared storage -> Download -> cD_Import.

A: Go to Player Settings -> General and turn on the remote-control switch. Then press and hold the OK and Back buttons on the remote at the same time until the LED flashes quickly and enters pairing mode. Next, search for STREAMER-REMOTE6 in the player’s Bluetooth settings and connect.

A: Follow these steps in order:

Step 1: Check whether the device is overheating

• Touch the top cover and check whether it feels noticeably hot.
• Check whether the device is placed in a well-ventilated area. Do not place it inside a closed cabinet.
• Check whether the room temperature is too high. Keeping the room below 25 C is recommended.
• If the device is overheating, power it off, unplug it, wait about 30 minutes for it to cool down, lower the room temperature with air conditioning, and then restart it.

Step 2: Clear background apps

• Exit unused streaming apps such as NetEase Cloud Music and Apple Music.
• Go to Settings -> App Management and clear app caches.

Step 3: Restart the device

• Long-press the power button or unplug the power to restart.
• Restarting usually fixes most temporary lag issues.

Step 4: Check the firmware version

• Go to Settings -> About Device and check whether the firmware is up to date.
• If it is not the latest version, upgrade the firmware and test again.

Step 5: Restore factory settings

• Use this only if all steps above do not solve the issue.
• Go to Settings -> Factory Reset.
• Note: this will erase personal data and installed apps.
• If the device is still lagging after reset, contact customer service.

A: This is a typical sign of USB interface instability. Please check as follows:

1. Open the local player app and check whether the spectrum is moving on the home screen.

• If the spectrum is moving, the streamer output is normal and the issue is not with the streamer.
• If the spectrum is not moving, no audio data is being output.

1. Check the output port setting and see whether it has automatically switched to optical or HDMI. A brief USB instability can sometimes cause misdetection.
2. Identify the symptom:

• The progress bar moves but there is no sound: high-sample-rate playback may have triggered USB drop-out.
• Master quality selected from the mobile app is also silent: this may indicate a USB hardware issue.

Root cause: the USB interface is unstable. High-sample-rate playback can trigger USB enumeration or drop-out, causing the system to switch automatically to optical output.

Solutions:

• You can request a replacement if the device is within the 7-day return or replacement period.
• Upgrade to the version with external USB 3.0 flash for improved stability.
• The current software version includes USB abnormality prompts.
• Try a higher-quality USB cable.

A: Open App Center, long-press the corresponding music app, go to App Info, select Storage and Cache, clear storage, then reopen the app and log in again. This method applies to NetEase Cloud Music, QQ Music, and similar apps when playback is abnormal, buttons do not respond, or playlists behave incorrectly.

A: Some tracks in Apple Music may fail to play due to official copyright and regional licensing restrictions. Audio resource access may be blocked by the platform. This is a normal platform limitation.

A: Check whether Crossfade is enabled in Apple Music on your phone. If this function is enabled, the device may become silent when the next song starts. On iPhone, go to Settings -> Music and turn off Crossfade.

A: EQ only supports songs with a sample rate of 192 kHz or lower. When playing songs above 192 kHz, EQ is automatically disabled. This is a normal product limitation.

A: This is a software compatibility issue between the device and the DAC. It is not a device fault.

• First check the model name on the DAC nameplate.
• If you know the model, contact customer service and provide the model so that the technical team can make a compatibility adjustment.
• If you do not know the model, we recommend sending the DAC to the company for compatibility adjustment.
• If sending it in is inconvenient, contact customer service to discuss other options.
• We recommend using official Kaiboer DAC products with Kaiboer streamers for better compatibility.

A: Try unplugging the USB drive, or switch to another USB output port and test again. In some cases, the issue may be related to USB power supply, port occupation, or device recognition.

A: Follow these steps in order:

Step 1: Check the cables

• Confirm that the audio output port on the streamer, such as RCA, XLR, optical, coaxial, or USB, matches the input port on the amplifier.
• For example, if the streamer uses RCA output, the amplifier must be switched to the corresponding RCA input channel.
• Make sure the cable is firmly inserted and is not connected to the wrong port. Many users accidentally connect output to output or input to input.

Step 2: Check volume and output settings

• Go to Settings -> Audio and set the main volume to maximum.
• Confirm that the correct output port is selected. If USB is connected, do not select optical or HDMI.
• Play a song in QQ Music and turn up the device’s volume knob.

Step 3: Restart the device

• Keep the cables connected and restart the streamer directly.
• Many cases recover after a restart.

Step 4: Test with music on a USB drive

• If the first three steps do not solve the issue, insert a USB drive and play local music.
• If there is sound, the streamer output is normal and the issue is likely related to streaming apps or the network.
• If there is still no sound, the streamer may have a hardware issue. Contact customer service.

Note: Do not skip the order. Most no-sound cases can be solved in the first two steps.

A: Restart the device directly while keeping the cables connected.
