⚡ ⚠️ Important Usage Guidelines
- CRITICAL: Power Supply Requirement! Utilize a stable DC 8-24V switching power supply that consistently delivers ≥5A current. Using an underpowered supply may lead to weak output, distortion, or permanent damage to the unit.
- Heat Sink Necessity! For operation exceeding 30W or during extended high-power usage, attaching a heatsink to the chip is mandatory (available separately). Overheating could trigger protective muting or cause permanent failure.
- Impedance Considerations: This amplifier is recommended for use with speakers of 4Ω or 8Ω impedance. Connecting loads below 4Ω is not advised.
- Proper Connection Sequence: Always connect the power supply and speakers prior to plugging in the audio input signal to prevent unwanted popping sounds.
