Product Information:

As a DMR repeater product with ergonomic design, totally digital functionality, the SR-RPTR helps to improve management efficiency and a faster response in emergency situations.


Professional 1U Design

Professional 1U design saves installation space.

Outstanding Heat Dissipation

The unique cooling design combines a built-in heat pipe and four fans design ensuring very efficient heat dissipation, preventing the repeater from over-heating in high output power mode.

Smart Digital-Analog auto detection

SR-RPTR can be configured to analog, digital or mixed mode. When configured to mixed mode, the repeater can dynamically switch between analog and digital depending on the type of call it receives.

Accessory Expansion

SR-RPTR supports third party development via a rear port of the repeater. This is achieved via the pin control through the repeater ports. Sip and AIS protocol supported for easy expansion.

IP Connecting

IP connection is a function which enables repeaters in different areas to switch data, voice and packets over a TCP/IP based network.

LED Indicator

9 LED indicators on the front of panel enables you to identify the repeater status clearly.

Software Upgradable to DMR Tier2 or Tier3

The advanced features can be upgraded to your existing SR-RPTR repeaters by software without purchasing a new one. By software upgrade, the repeater can be used as a DMR Tier2 repeater or DMR Tier3 transceiver.
