The M7CL series is a digital live-sound console that carries on the digital evolution from the acclaimed PM1DV2 and PM5D consoles. This package includes 48 channel digital live console with built in EtherSound ports & internal PSU with Meter Bridge & 3 x SB168-ES Stage Boxes.

Where the original M7CL-48 has 48 analog inputs, the M7CL-48ES has a total of three EtherSound ports: two for connection to as many as three Yamaha SB168-ES EtherSound stage boxes in either daisy chain or ring configuration. The 3rd port allows permanent connection to a computer while the stage boxes are connected in ring mode.

To set up a basic daisy-chain system all you need to do is connect the M7CL-48ES to the SB168-ES stage boxes via appropriate cables and turn on the power. The ESMonitor software is not required. Everything is configured automatically, and you don't even have to set or worry about the order of the ID numbers of the SB168-ES units used. Switch a few settings and setting up a ring network is just as easy.
