BDI GPM-300-8 Crosspoint Switcher

Low-Cost Broadcast Audio Routing In One Rack Space

The BDI GPM-300-8 is a general-purpose audio matrix (crosspoint) switcher built to route stereo audio where you need it, fast. It’s designed for broadcast and professional audio plants that need dependable source selection, backup switching, and flexible routing without filling a rack with single-purpose boxes.

8x8 Analog Stereo Matrix Switching For Real-World Plants

Configured as the “-8” model, this unit provides 8 stereo analog inputs and 8 stereo analog outputs, letting you route any input to any output for studio feeds, control room monitoring, distribution to codecs, or plant-wide source sharing. It’s a practical fit for radio stations, TV facilities, houses of worship, and production racks where clean audio switching and clear routing control matter.

Automatic Silence Detection And Failover You Can Rely On

Every output includes its own silence sensor, so the switcher can automatically flip away from a dead or quiet source to a backup feed when trouble hits. That’s a big deal for unattended operation, automation chains, network joins, and emergency workflows where dead air isn’t an option. When the primary audio returns, auto-revert can switch things back so you’re not stuck babysitting your routing.

Switcher-Within-A-Switcher A/B Presets For Instant Backup Control

Beyond basic crosspoint routing, the GPM-300 platform supports an A/B-style workflow where each output can have preset “A” and “B” inputs. That means you can treat the unit like multiple independent A/B switchers inside one chassis—ideal for redundant sources, shared services, or “normal vs backup” routing that operators can manage quickly.

Front-Panel Control Plus Remote Integration Options

Routing and configuration can be managed at the unit, and the design is intended to play nicely with broadcast control methods for remote selection and status monitoring. This makes it a solid choice for facilities that want both on-site control and the ability to tie switching behavior into automation, GPIO-style logic, and larger plant control strategies.

Built For Broadcast Use Cases Like EAS And Emergency Sharing

If you’re building around EAS sharing, network feed distribution, N+ backup studio requirements, or emergency studio sharing, this switcher is aimed directly at those workflows. The combination of matrix routing, A/B presets, and silence-triggered switching is the kind of tool that keeps a plant sounding professional even when a source fails mid-show.
