Overview
The 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 of such reverse signals is sufficient for most installations. Active RDL modules are available for complete isolation if required. The D SERIES-A2 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 D SERIES-A2 is not intended as an audio input panel.
The D SERIES-A2 fits directly into back boxes, available from RDL, to fit cabinets or US or international walls (RDL WB-1U). It may also be mounted directly into cabinets or most standard US single gang electrical boxes.
Features:
- Wall Mounted Consumer Level Outputs
