BDI GPM-300 Series General Purpose Matrix /AES Synchronous Audio Switcher

GPM-300 Series General Purpose Matrix /AES Synchronous Audio Switcher

The GPM-300 Series matrix switcher is a cross-point 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 configrations. 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 cross-point switcher functionality is also available for emergencies so that any input can be routed to any output. Uses include EAS system sharing, network join sharing, emergency studio sharing for N+ backup studio requirements. Each output has its own silence sensor for automatic switch over in case of primary feed failure. An auto revert feature allows the switcher to return to the primary feed when audio has been restored to the failed channel. The GPM-300 series switchers provide flexibility and value for any broadcast or professional audio plant.
