The Eartec 4-User SC-1000 Two-Way Radio System with Monarch Inline PTT Headsets is a complete system that consists of 4 of the company's Scrambler SC-1000 UHF radio transceivers, each with its own Monarch Inline Headset with Push-to-Talk activation.

The SC-1000 system allows for crystal clear voice communication to production teams on the move. This wireless transmitter operates in the simplex mode, which means that when one person in a group transmits, the message is received by everyone. An unlimited number of transceivers can operate at the same frequency and the system can also be utilized as a dual-channel intercom with switching.

This transceiver features a full watt of transmission power at a distance of up to 1 mile (1.61 km). It utilizes UHF high-band frequencies that can penetrate concrete or steel surfaces. This makes the SC-1000 a cost-effective sound solution for schools, churches, community theatres, or any on-location venue where users need to communicate between buildings or through walls. This unit operates with a rechargeable lithium polymer battery (included). It also comes with a military belt clip for convenient carrying.

The Edge Inline Headset with Push-to-Talk activation is a versatile headset accessory for the SC-1000 radio transceiver. Each Edge headset includes a streamlined inline PTT button and clothing clip as well as a 2-pin radio plug. This allows you to clip the radio to your belt as well as send and receive voice messages through the headset.
