How to connect Boom with a Monitor Controller

Boom's Main and Headphone outputs can be connected to any external Monitor Controller with Line Inputs.  Both outputs provide a +4dBu balanced line output level when set the output volume is set to the maximum (0) in the Apogee Control 2 app.  

When an output is connected to a Monitor Controller set the output level to 0 (max output) for no attenuation to this Line Output level.   Then you will adjust the output volume from the monitor controller.

Note - Only one output is active at a time.
