THE GPM-300 SERIES CROSSPOINT SWITCHER
FLEXIBLE DIGITAL AND ANALOG AUDIO ROUTING
The GPM-300 is an analog and digital crosspoint switcher
The new GPM-300 Series matrix switcher is a basic crosspoint switcher and provides
a low cost solution to your digital and/or analog audio routing and switching needs.
Scalable modular design lets you purchase only what you need with room to expand.
DSP Architecture provides outstanding flexibility and reliability in a single rack chassis. Example application would be one EAS generator (digital or analog source) connected to the GPM-300 series matrix switcher. The GPM-300 can now switch the
single EAS generator source to up to eight studios in your choice of digital/analog
audio, or both.

The GPM-300 can switch between analaog an digital sources depending on the requirement and system ordered from the above configuration chart. The GPM is intended for any application where high quality, synchronous AES switching is required.
Every digital input can accept from 8-96 KHz sample rates and are frame rate converted to 44.1 or 48KHz output sample rate which is user configurable. Call or email
us today with your requirements as this flexible system can be customized to meet
your exacting requirements.
