The D SERIES-BT1A is part of the group of versatile wall-mounted products from Radio Design Labs.  The standard mounting case can be directly fastened in North American electrical boxes or in RDL 
International wall boxes.
APPLICATION:  The D SERIES-BT1A modules are Bluetooth audio receiving modules compatible with RDL® Format-A twisted pair receivers. When paired with a 
compatible Bluetooth enabled device, the module receives stereo audio from the Bluetooth source.  The stereo signal is sent through two Format-A pairs to any RDL 
Format-A receiver.  A stereo/mono switch set by the installer permits summed mono audio to be sent over one switch-selected pair to the Format-A receiver.
If set for stereo operation, an additional Format-A source (set to Pair A) may be daisy chained with the D SERIES-BT1A to a three-pair Format-A receiver.  If set for 
mono operation, up to three D SERIES-BT1A modules may be daisy chained to a single three-pair Format-A receiver.  Connections between Format-A modules and 
Format-A receivers use standard CATx cable with RJ45 connectors.
The D SERIES-BT1A modules are powered from the Format-A receiver. The installer can customize the module name and programming password through the Bluetooth 
connection using a smartphone, computer or tablet terminal program. These modules feature studio-quality circuits and analog filters to provide audio performance 
exceeding expectations from consumer interface technologies.  High performance, simplicity of operation and efficiency of installation make RDL the best value in 
professional Bluetooth interfaces.
