Welcome to the official support page for the TempoTec V1. If you encounter any playback errors or streaming issues, please refer to the guide below to resolve them quickly.

1. Storage & Format Compatibility

To ensure optimal performance, please refer to the following specifications for your audio files and memory cards:

• Supported Audio Formats: MP3, WAV, FLAC, APE, WMA, OGG, M4A, AAC, MP2, AIF, AIFF.
• DSD/ISO: DSF, DFF, and ISO (Standard/Normal, non-DST).
• Micro SD (TF) Card Support:
• File Systems: Supports FAT32, exFAT, and NTFS.
• Max Capacity: Up to 2TB.
• File Storage Limits:
• Without CUE files: Up to 5,800 tracks.
• With CUE files: Up to 6,200 tracks.
• Note: The actual capacity for indexing depends on file formats and metadata size. Lossy formats (e.g., MP3) may allow for more tracks to be indexed, while Hi-Res formats (e.g., FLAC, DSD) with large metadata or album art may consume more indexing resources, resulting in a lower total count.

2. Troubleshooting Display Issues: Garbled Text (Mojibake)

Q: Why are song titles or lyrics displaying as garbled text (mojibake)?

A: Reason: This occurs because the character encoding of the audio file's metadata does not match the system language setting of the device, causing a parsing error.

Solution:

We recommend using Mp3tag or similar professional tag-editing software to re-encode the file information:

1. Open the problematic file(s) in Mp3tag.
2. Edit the ID3 tags or lyrics information.
3. When saving, ensure you set the character encoding to your Local Encoding (matching your target language).
4. Save the changes and re-import the file to your device.

3. Playback Error Code Reference

If you encounter an error message during playback, please refer to the table below for quick diagnostics:

4. Frequently Asked Questions (FAQ)

Q: Why do I see a "400 Error" (Bad Request) on Qobuz?

A: This is usually a handshake failure caused by a system time mismatch.

• Solution: Go to Settings > Date & Time. Enable "Network Auto-Sync" and ensure the time format is set to 24-hour. Proper time synchronization is required for secure SSL server communication.

Q: I am receiving an "SAE_IO -13" error. How do I fix it?

A: This code indicates a general read/communication failure:

• Local Playback: The SD card may be corrupted. Try testing with a different SD card.
• External Devices: If using a USB DAC or Bluetooth, verify compatibility and cable connections.
• Streaming: If using Tidal or Qobuz, verify that your Wi-Fi connection is stable.

Q: How can I resolve playback issues with "SAE_RANGE -11"?

A: This indicates that the audio file's sample rate is higher than what TempoTec V1 can decode (e.g., extremely high-resolution DSD files). Please confirm the file specification and ensure it is within the supported range of your device.

Q: My device is giving me a "SAE_USED -5" error. What should I do?

A: This indicates an internal module exception. Please visit our official download center to ensure you are running the latest firmware version. If the error persists after a firmware update, please contact our support team with your current firmware version and a description of the issue.

Q: I am receiving an "SAE_NOTSUPPORT -12" error. What does this mean? A: This error indicates that the file format is incompatible on TempoTec V1. Please check for the following common scenarios:

1. Unsupported DST/DSD Formats: While TempoTec V1 supports DSD (DSF/DFF), it does not support DST-compressed DSD files (often found in certain SACD ISO rips). Please ensure your DSD files are in non-DST formats.
2. DRM-Protected Files: If you have downloaded music for offline listening from streaming services such as Apple Music, Tidal ,Qobuz or other Stream media app, please note that these files are encrypted with DRM (Digital Rights Management). The V1/V3 Blaze cannot decode these protected files. You must use a compatible player app or source your music from DRM-free platforms.
3. General Incompatibility: For other file types, ensure they match our list of supported formats. If the file is a standard format, try converting it to WAV or FLAC using a trusted audio converter (e.g., Foobar2000).

Q: How does the device prioritize album artwork, and what are the recommended file specifications?

A: To ensure your album art displays correctly, the system follows a specific Priority Logic and adheres to certain File Size Limits.

 1. Recommended Artwork Specifications

Please ensure your image files meet these requirements to avoid display errors:

• JPG: No specific size limit (Best compatibility).
• PNG: Maximum resolution of 1024x1024.
• BMP: Maximum resolution of 2048x2048.

 2. Artwork Display Priority (Search Order)

When the device scans for artwork, it searches in the following order of priority. It will stop at the first valid image it finds:

1. Embedded Artwork: Artwork stored directly within the audio file (ID3 tag).
2. Same-name File: An image file in the same folder as the song that shares the exact same filename as the song.
3. "Front" Prefix: An image file in the folder starting with "front" (e.g., front.jpg).
4. "Cover" Prefix: An image file in the folder starting with "cover" (e.g., cover.png).
5. "Folder" Prefix: An image file in the folder starting with "folder" (e.g., folder.bmp).

Note: For all external image files (options 2-5), the system supports BMP, JPG, and PNG formats.
