3. Key Considerations for Choosing a PA Amplifier

3.1 Power Requirements and Wattage Considerations

Wattage matters! Consider the size of your venue and the number of speakers you plan to use. If you’re hosting a neighborhood bingo night, you won’t need a powerhouse amp that could power a rock concert. On the other hand, if you’re rocking the main stage at Coachella, you don’t want your sound drowned out by the crickets. Find the sweet spot that matches your power requirements.
