Broadcast Audio Router And Switcher For Critical Signal Paths
The BDI GPM-300-10 Crosspoint Switcher is a rackmount broadcast audio routing toolbox built to switch and route program audio quickly and reliably across a facility. It’s designed for engineers who need deterministic routing for on air chains, studio to transmitter links, backup sources, and shared feeds, with switching behavior that supports both daily operations and emergency recovery.
Crosspoint Switching That Routes Any Input To Any Output
At its core, the GPM-300 platform is a true crosspoint matrix switcher, meaning you can route any available input to any available output as needed. This is ideal for broadcast plants that need flexible audio routing without repatching, and it supports fast reconfiguration when formats change, studios swap roles, or a backup path needs to come online.
AES Synchronous Switching For Clean Digital Transitions
For facilities working with AES3, the GPM-300 series is built for synchronous AES switching designed to avoid clicks, pops, and other artifacts that can happen during digital source changes. This makes it well suited for network joins, automation driven switching, and redundancy scenarios where audio continuity matters, especially when multiple sources must be switched under time pressure.
Integrated Silence Sensing For Automatic Backup Switching
An integrated silence sensor per output helps protect your air chain by detecting loss of audio and switching to a designated backup source automatically. Silence detection parameters are typically configurable so you can set threshold behavior and timing that makes sense for your content, and an auto revert style workflow can return routing to the primary feed once audio is restored.
Analog I O Routing For +4 dBu Broadcast Workflows
This version is specified with analog I O, making it a practical fit for plants that still rely on balanced analog feeds for consoles, processors, STL equipment, codecs, or legacy sources. Analog routing in a matrix format is especially useful when you need to share a common source to multiple destinations, create emergency studio sharing paths, or build a simple N plus backup studio strategy.
Remote Control And System Integration For Broadcast Operations
A broadcast audio switcher is only as useful as its control options, and the GPM-300 family is commonly used in environments that require external control from automation systems and facility logic. This makes it a strong match for radio and TV plants where routing needs to be triggered by events, GPIO logic, or centralized control systems rather than manual front panel changes.
