What to Consider When Choosing an Amplifier for Outdoor Festivals
- Power Output
Outdoor spaces swallow sound, so you need an amp with enough wattage to reach everyone. At least 750 watts per channel is recommended, but for bigger events, go higher. - Durability and Cooling
Festivals can be tough on equipment, especially with outdoor conditions like heat, dust, and moisture. Look for amplifiers with strong cooling systems and durable casings to avoid any mid-event hiccups. - Portability
You don’t want to be wrestling with bulky equipment when setting up. A lightweight amplifier can save you time and effort, especially if you’re moving gear between stages. - Sound Control (DSP)
Built-in DSP gives you more control over your sound. You can adjust EQ, crossover settings, and even limiters to tailor your sound for different parts of the venue. - Compatibility
Make sure your amplifier works with the rest of your sound system—whether it’s speakers, mixers, or other equipment. Check the inputs and outputs (XLR, TRS, SpeakON) to ensure a smooth connection.
