Radio Design Labs DB-A2
Line Output Assembly

OUR PART #  DB-A2


RDL's DB-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 DB-A2 circuit design provides a high degree of audio isolation if a user accidentally feeds a consumer-level source into the DB-A2. The attenuation of such reverse signals is sufficient for most installations. Active RDL modules are available for complete isolation if required. The DB-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 DB-A2 is not intended as an audio input panel.

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

  • Wall Mounted Consumer Level Outputs
  • Single or Dual Outputs from Mono Source
  • Gold Plated Phono Jack Outputs
