ABL 100

The ABL 100 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 8×8 or greater matrices.
The possibility of regulating the level of each output means that the ABL 100 can also be used as impedance adapter between non-standard sources and destinations.
