From the Manufacturer
The Bricasti Design Model 10 remote console is a dedicated hardware remote controller for use with the M7 stereo reverb processor. Following the same design criteria as the M7, the M10 casing is manufactured and milled from solid anodized aluminum, for an enduring design and long life. The M10 is also designed to be simple to use, and easy to interface; utilizing a standard RS422 serial interface. In application, it can be very useful when using more than one M7 or when there is a need to be more in the sweet spot when making adjustments in a large mixing environment.
