The EcoFlow Delta 3 Ultra provides a massive 3600W of clean, silent power - enough to run your entire front ensemble audio system, from digital consoles and wireless microphone equipment to high-powered loudspeakers. No more worrying about finding a working outlet at the stadium or running a loud generator near your front ensemble.
The Silent Partner for Your Band:
- Stadium-Ready Output: With a 7200W surge capacity, this unit won't "trip" when your subwoofers hit a heavy bass drop or when you power up multiple speakers at once.
- Whisper-Quiet Operation: At only 30dB, it is virtually silent. You can place it directly inside or next to the sound cart, and it won't interfere with your front ensemble microphones or distract the judges.
- All-Day Rehearsal Power: The 3072Wh capacity means you can power a standard audio system through a full 8-hour band camp day without needing a charge.
