Description

Long-Range Megaphone with Emergency Whistle Function

The Toa ER-520W Megaphone with Whistle is a professional communication device designed for situations requiring both voice communication and emergency signaling. Featuring a powerful whistle function that projects up to 315 meters alongside a 250-meter voice range, this megaphone provides versatile communication capabilities. With 10-hour battery life for voice operation, it’s ideal for extended events, security operations, and emergency response situations where both clear announcements and attention-grabbing signals are necessary.

Dual-Function Design for Professional Applications

This megaphone combines clear voice amplification with an effective emergency whistle in one compact unit. The whistle function serves as an emergency alert signal that can be heard at greater distances than voice (315m vs 250m), making it particularly valuable for crowd control, emergency alerts, and attention-getting in noisy environments. Powered by 8 AA batteries, it delivers reliable performance throughout long shifts or events.
