ICOM SP-AT1 Surveillance Earpiece
Description
Discreet Listen-Only Audio
The SP-AT1 delivers received radio audio directly to one ear without using the radio or speaker microphone’s external speaker. The transparent acoustic tube keeps the setup less noticeable and helps limit radio traffic from being heard by nearby people.
It is suitable for:
- Security and surveillance teams
- Event and venue staff
- Hospitality and retail operations
- Dispatch and coordination personnel
Quick-Disconnect Acoustic Tube
The coiled acoustic tube can be disconnected from the cable assembly. This makes it easier to clean or replace the tube and earpiece without replacing the complete accessory.
3.5 mm Audio Connection
The SP-AT1 uses a right-angle 3.5 mm single-pin plug. It connects to compatible ICOM radios or remote speaker microphones equipped with the appropriate 3.5 mm earphone jack. Compatibility should be confirmed for the specific radio or microphone before purchase.
Reinforced Cable
The cable is Kevlar-reinforced to provide added resistance to pulling and everyday wear. The acoustic tube measures approximately 9 inches when at rest.
