Protea 24.24M Matrix Processor
Features and Specs
November 1, 2004
The Protea 24.24M Matrix Processor uses modular expansion cards to provide up to twenty-four channels
of audio matrixing and processing. The base unit offers a four-input four-output confi guration. Each
input and output expansion card has an individual DSP processor allowing you to expand the base unit’s
total inputs or outputs four channels at a time. These cards are easily installed. Matrixing allows you to
route any input
