AM414 is a stand alone line-level combiner which is the ideal choice for requiring the passive, isolated mixing of two balanced line-level audio sources to feed a balanced audio output. 

The input circuits are line-level and are each isolated from each other. Therefore the unit may be used to bridge a balanced stereo source without affecting the stereo separation. 

The balanced output has a Ground Lift switch that is fitted to help combat ground loop.
