Broadcast Devices - Digital and analog crosspoint audio switcher

The GPM-300 Series matrix switcher is a crosspoint switcher which provides a low cost solution to your digital and/or analog audio routing and switching needs. Models are available in 4 or 8 channel versions with 10 different I/O configurations.

Digital signal processing (DSP) architecture provides flexibility in a single rack chassis. The GPM-300 also has a “Switcher in Switcher” mode whereby each output can have pre designated A / B inputs which can be programmed from any of the inputs available. This feature is useful for common source sharing or for individual switchers in one chassis. 
The crosspoint switcher functionality is also available for emergencies so that any input can be routed to any output.
