I. Function & Performance Clarifications

1. Power Output & Supply: The TB10D’s maximum power output is determined by the power supply. With the included 32V 5A power supply, it delivers 100W at 4Ω and 130W at 8Ω. For higher power, a 48V 10A power supply is recommended, which can provide 280W at 4Ω and 300W at 8Ω per channel. The maximum chip power of 600W (300W per channel) requires a 48V 10A power supply. 2. Connections & Compatibility: This amplifier supports RCA input only and is not compatible with Bluetooth. It is designed to connect to a pair of passive speakers or bass shakers, not subwoofers or four speakers. The terminating impedance supports 2 – 8Ω. 3. Accessories & Dimensions: The package includes only a 32V 5A power adapter. No other cables are included. The product dimensions are 5.59×4.13×1.38 inches.

II. Noise – Related Solutions

1. Cable Quality: Use 100% shielded RCA cables to significantly reduce hissing sounds. Ensure all cables are properly connected and undamaged. 2. Power Adapter: Use the original power adapter provided with the product to avoid white noise. Non – original power adapters may introduce additional noise. 3. Audio Source Quality: Use high – quality audio files (FLAC, WAV) instead of compressed formats (MP3). Place speakers at least 30cm away from walls or corners to improve sound quality. 4. Environment & Setup: Avoid using the device in environments with strong magnetic fields. Ensure the surroundings of the device are clean and tidy. Keep the device away from other electronic devices that may cause interference. 5. Volume & Mute Settings: Ensure that the volume levels of both the amplifier and the television are properly adjusted and not set to mute. Set the volume to 50% or below to reduce noise. 6. Speaker Compatibility: Ensure your speakers have an impedance between 2 – 8Ω. Avoid using the amplifier with subwoofers or as a car amplifier.

III. Troubleshooting Guide

1. Power Output: To achieve the specified power output, ensure you are using the correct power supply. For higher power, consider purchasing a 48V 10A power supply.

2. Audio Sound: Use high – quality audio files and optimize speaker placement. Use 100% shielded RCA cables and the original power adapter. Check for incorrect wiring, interference, and ensure audio cables are in good condition. Avoid using a power socket for multiple devices simultaneously.

3. Compatibility: Ensure your speakers have an impedance between 2 – 8Ω. Avoid using the amplifier with subwoofers or as a car amplifier.

4. Function: Ensure all cables are correctly connected, secure, and in good condition. Ensure that the volume levels of both the amplifier and the television are properly adjusted and not set to mute.
