The Show ER-66 25W Hand Mike Megaphone projects audio across 500 to 700 meters with an integrated siren. Its ABS and metal chassis maintains structural integrity during field operations. This version upgrades power from 15W to 25W and adds a 260-second recording loop.
Key Features
- Siren & Whistle: Integrated 110dB signal tones for emergency crowd control. These tones penetrate ambient noise but fail against heavy machinery.
- USB/SD Playback: Digital ports accept FAT32 formatted external media files. This system plays repetitive audio but rejects encrypted files.
- Detachable Coiled Mic: PTT microphone unclips with a 1.5-meter coiled cord. The cord extends reach but requires a manual trigger.
- 25W Power Output: High-gain amplification drives audio signals up to 700 meters. Sound pierces road dust but dissipates in heavy rain.
- 260s Recording: Internal solid-state memory stores 4.3 minutes of looped audio. It automates voice instructions but clears when power dies.
