The stainless steel DS-A2 Line Output Assembly from RDL is a passive audio output assembly that provides one or two unbalanced consumer level audio outputs from a balanced line-level audio source. It may be connected to the +4 dBu line level output of any RDL product, even if that output is simultaneously feeding other equipment. The DB-A2 circuit design provides a high degree of audio isolation if a user accidentally feeds a consumer-level source into it. The attenuation of such reverse signals is sufficient for most installations. The output jacks are transformer isolated from the balanced line input, and the input shield is separated from the case ground to reduce the possibility of induced hum.

The DB-A2 assembly may also be mounted directly into cabinets or most standard US single gang electrical boxes. It fits directly into back boxes (available separately) from RDL to fit cabinets or US or international walls.
