Model D SERIES-A2
Audio Output Panel

The D SERIES–A2 audio panels are audio output accessories from Radio Design Labs offered in Decora® plates. The D SERIES panels are finished in
RDL’s grey/white color, black or in stainless steel. These output panels are intended for installations demanding the ultimate in professional styling combined
with durability, longevity and value.

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

APPLICATION:

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

The -A2 fits directly into back boxes, available from RDL, to fit cabinets, US or European walls
(RDL WB-1U). It may also be mounted directly into cabinets or most standard US single gang electrical
boxes.

Wherever style, performance, and value are required for wall or cabinet mounted audio outputs, the

-A2 is the ideal choice. Use them individually or in conjunction with other RDL products as part of a
complete audio/video system.
