BDI GPM-300-7 Crosspoint Switcher

Audio Routing And Switching In One Rack Space

The BDI GPM-300-7 is a compact crosspoint matrix switcher designed for broadcast and pro audio routing, letting you quickly assign any available input to any output when your studio, rack room, or transmitter site needs fast, dependable switching.

Analog I O For Broadcast Signal Paths

Built around balanced analog audio workflows, this configuration provides an 8 input and 4 output layout that fits common program, preview, utility, and backup routing needs, making it a practical tool for day to day plant routing without a full size router frame.

Silence Detection With Automatic Backup Switching

Each output includes its own silence sensor so you can respond to a lost feed automatically, set your preferred thresholds and timing, and keep audio on air by switching to a designated backup source, with auto revert available when the primary channel returns.

Switcher Within A Switcher For A B Source Control

The switcher in switcher mode allows each output to have pre assigned A and B sources that can be changed instantly, which is especially useful when multiple rooms share common feeds, when you want easy redundancy, or when you need several small switchers inside one chassis.

Remote Control For Engineering And Automation Systems

Control the unit from the front panel, via GPIO, or over Ethernet for network based management, and integrate it with broadcast automation through RS232 or RS485 for straightforward switching, monitoring, and remote site operation.

DSP Based Architecture For Flexible, Consistent Operation

The GPM-300 platform uses DSP architecture to support flexible routing features in a single rack chassis, helping broadcast facilities handle emergency routing, shared resources, and reliable program switching while keeping the system compact and service friendly.
