BDI GPM-300-6 Crosspoint Switcher

BDI GPM-300-6 Crosspoint Switcher

The Broadcast Devices (BDI) GPM-300-6 is a 1RU general-purpose matrix audio switcher built for broadcast routing and AES3 digital audio switching. This model is the all-digital 8-input/8-output AES configuration, designed to route any AES3 source to any AES3 destination with synchronous switching for clean, glitch-free transitions.

AES3 8x8 Routing For Studios, EAS, And Backup Feeds

If you’re wiring a radio plant, TV facility, or network operations rack, the GPM-300-6 handles common routing jobs like studio-to-transmitter path selection, network join routing, EAS generator sharing, and emergency source switching. The “Switcher In Switcher” A/B logic lets each output behave like its own dedicated A/B selector when you need fast, predictable fallback behavior.

Silence Detection With Automatic Switch And Auto Revert

Each output includes its own silence sensor, with programmable settings such as threshold and time delay, so the router can automatically switch away from a failed or silent feed. When audio returns, auto revert can bring you back to the primary source without operator intervention, which is ideal for unattended redundancy and transmitter protection workflows.

Sample Rate Conversion On Every AES Input

On the AES side, each digital input supports sample rate conversion for better compatibility when different studios, codecs, or playout systems don’t all run the same clock settings. This helps keep digital audio routing stable and predictable across mixed-source environments.

Remote Control Via GPIO, Serial, And Ethernet SNMP

For integration, the GPM-300 series supports remote control over parallel GPIO and RS-232/485, plus Ethernet connectivity for SNMPv2 and BDI GUI options. That makes it a strong fit for automation systems, engineering remote control, and centralized monitoring where you want routing control and status without living in the rack room.

Rack-Ready DSP Architecture Built For Continuous Duty

The GPM-300 platform is a DSP-based routing solution in a standard 19-inch, single-rack chassis intended for always-on audio plant operation. If your goal is straightforward, dependable AES3 crosspoint routing with silence-sensing safety nets, the GPM-300-6 is the dedicated 8x8 AES version in the line.
