Input Expander
EXi8 input expanders convert analog microphone/line audio to digital and transmits the signal using Yamaha's YDIF format. The EXi8's preamps can be controlled remotely from MTX/MRX series processor via Ethernet cable.
Output Expander
EXo8 output expanders feature 8 channels of DA converters that produce high quality analog audio by converting digital output from MTX/MRX series processors via YDIF.
