Interconnecting Made Easy.
Audio Bridging With Interoperability Gateways
Ensuring organizations can meet the demands of modern command and control, the 619 range of audio bridges provide a uniform way to interconnect radio equipment from different manufacturers and in different bands. Having a reliable means of connecting people is essential for a number of industries, and Omnitronics have developed the equipment to bring people together through efficient communications.
Typically, audio bridges are used to interconnect multiple repeaters together at a remote site, and to provide multiple paths within a radio network for ultimate interoperability. The ability to connect multi-site networks is paramount to the mission of all organizations that are involved in providing a service to our communities.
619EI
Designed for organizations with less comprehensive requirements, the 619EI is a highly reliable and robust six-port audio bridge that is remarkably easy to install and configure. That simplicity of implementation isn’t reflected in the range of applications, however – the 619EI is an ideal choice for HF/VHF/UHF radio networks, audio bearer systems, data, model splitters/combiners and public safety address systems.
619DSRI
The more sophisticated option in Omnitronics’ range of audio bridges, the 619DSRI is an eight-port digital bridge providing the highest level of functionality available. The powerful features can be easily integrated into your dispatch system, using dynamic configuration to increase the effectiveness of radio networks.
Typical applications for the 619 range of Interoperability Gateways:
- Cross-banding disparate radios – Increasing interoperability is the core application of audio bridges. Connecting multi-site networks, whether they carry equipment from different manufacturers or on different frequency bands, is the most common usage scenario. Radios in any band are able to be interconnected, including HF, VHF, UHF, Airband, Marineband, P25 and Trunked.*
- Rebanding and narrowbanding – Many organizations have faced challenges with new regulations requiring the rebanding of radios onto a narrower frequency. Using an audio bridge simplifies this process, allowing you to install new equipment over a period of time rather than all at once. The audio bridge lets new and legacy units run in parallel, meaning there’s no downtime in the changeover.
- Network reconfiguration on demand – Some radio networks require reconfiguration, however traditionally the process has been somewhat complicated. With an audio bridge, it’s possible to preconfigure various link paths that can easily be activated over an RF link or IP network.
- Linking pagers to modern radio protocols – While they may not be as common as they once were, in some organizations pagers are still a popular and efficient means of communication. Interoperability with modern radio technologies isn’t assured with the ageing devices, but an audio bridge can connect them easily.
- Automatic steering – Audio bridges can be configured to re-route incoming transmissions based on a defined event. For example, in hazardous environments where a failed network could present a significant danger, audio bridges can automatically steer communications to a backup system.
- Fast link keying – Designed to eliminate long delays in CTCSS-controlled multi-hop links, a fast CTCSS mode is incorporated into the 619DSRI for input signals.
Interoperability Gateways provide a means of creating a wide variety of network connections to facilitate interoperability across frequency bands, making sure your organization can communicate efficiently. Both the 619EI and 619DSRI are built for reliability and durability, with a number of Omnitronics’ clients operating the devices for over 20 years.

Audio Bridging: Real-World Applications
Audio Bridging provides a uniform way of interconnecting radio equipment from different manufacturers and in different frequency bands. Typically this is done at the repeater remote site to provide multiple paths within a single radio network. However, with advances in technology a vast array of additional applications are possible.
