RDL D-A2 Line Output Assembly - RCA jacks, Terminal blockThe D SERIES A2 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 D SERIES A2 circuit design provides a high degree of audio isolation if a user accidentally feeds a consumer level source into the D SERIES A2. The attenuation
