The ABL100 unit is an appliance that transforms an unbalanced audio signal into a balanced audio signal.

Its configuration with 8 incoming and outgoing stereo signals means it is suitable for use in cascade of 8x8 or greater Matrix Switchers.

The possibility of regulating the level of each output means that the ABL100 can also be used as impedance adapter between non-standard sources and destinations.
