Troubleshooting and Important Notes
To ensure optimal performance and avoid common issues, please consider the following:
- Subwoofers/Passive Speakers: We do not suggest using this product with subwoofers or passive speakers that exceed 150W. If the power of the subwoofer exceeds 150W or if used with passive speakers without an additional amplifier, the sound output will be too low or non-existent. An additional amplifier is required for high-power subwoofers or passive speakers.
- TV Size and DVD/CD Players: This product is not suitable for TVs larger than 86 inches or for use with DVD/CD players. Using it with these devices may result in audio distortion and degraded sound quality.
- Musical Instruments: We do not recommend using this product for electric guitars or electric pianos, as it may cause excessive audio delay and poor sound quality.
- Router Interference: Do not place the transmitter or receiver too close to a Wi-Fi router (2.4G/5.8G). Proximity to a router can cause transmission slowdown, increased delay, and degraded sound quality due to interference.
- Cable Usage: Always use the provided RCA to 3.5mm audio cable. Using an RCA to RCA cable may cause excessive delay and distortion.
- Surround Sound/Rear Speakers: This product is not recommended for surround sound setups or for connecting rear speakers, as it may not meet the specific requirements for these applications.
