        • Friendly Solutions Guide

          1. Check Connections & Device Compatibility: --Ensure all audio cables are fully inserted and undamaged. Replace any frayed cables with high-quality shielded ones (recommended: cables with metal connectors).-- Confirm your speakers' power rating (e.g., 50W/100W) and impedance (e.g., 4Ω/8Ω) match the amplifier's requirements (see product manual). If your speakers have an impedance outside the 4-8Ω range, they may not work optimally with the MC331. -- Avoid raising the volume beyond your speakers' labeled maximum (e.g., “Max 80%") to prevent distortion.

          2. Optimize Setup & Audio Sources: -- Speaker Placement: Use high-resolution speakers placed at least 30cm away from walls or corners. Add rugs or curtains to reduce echoes. -- Audio Quality: Play lossless music formats (e.g., FLAC, WAV) on dedicated devices (e.g., music players or updated phones/computers). -- Bluetooth Compatibility: Ensure your device supports SBC and AAC Bluetooth formats. Keep the Bluetooth device within 10 meters of the amplifier and minimize obstacles.

          3. Reduce Environmental Interference: -- Anti-Interference Cables: Use shielded RCA cables with grounding (metal-shell connectors) to minimize buzzing. -- Distance from Interference: Keep audio/Bluetooth cables ≥30cm away from routers, power outlets, or microwaves. -- Troubleshoot Sources: Test the same song on another phone/computer. If the noise persists, contact support for assistance.


        • Quick Tips:

          - Using a Turntable? Ensure it has a built-in phono preamp or connect an external one (required for proper volume).

          - Bluetooth Stability: Check if the antenna is securely installed and keep it away from other wireless devices (e.g., Wi-Fi routers).

          - Power Supply: Ensure you are using the correct power supply (24V 4.5A for 69W output; 24V 8.5A for maximum 105W output).

          - Warm-Up Time: Allow the vacuum tubes to warm up for 10-15 minutes after powering on to ensure stable performance.
