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.Main Features:Bluetooth Audio Input for Installed Sound SystemIntuitive Single Button Pairing with LED Status IndicationSpecial Software Not Required for Module SetupCustomize the Module ID Name and Programming Password through the Bluetooth ConnectionSends Received Bluetooth Audio to RDL Format-A ReceiversMono Summed or Stereo Audio Input Mode is Switch-Selectable on Rear PanelRear-Panel Switch Selects which RJ45 Pair (A, B or C) is Fed in Mono Summed ModeDaisy-Chain up to Three D SERIES-BT1A modules to One Format-A Receiver in Mono ModeRemotely Powered through Twisted Pair CableSignal and Power Pair Pass-Through on RJ45 JacksRequirements:To complete a Bluetooth setup using the D SERIES-BT1A Wall-Mounted Bluetooth Audio Format-A Interface, at least one compatible Format-A receiver and its recommended power supply must be used.Specifications:Output: RDL Format-A (RJ45)Format-A Input: RJ45 LOOP INFormat-A Signal Pair Used: A, B, or C (summed mono mode, rear-panel switch-selectable); B and C (stereo mode, pair A pass through)Frequency Response: 20 Hz to 20 kHz ( 0.5 dB)THD+N: < 0.1%Noise below -20 dBFS: < -70 dBCrosstalk (channel to channel): < 70 dBAudio Operating Levels: -20 dBFS = +4 dBu (balanced), nominalAmbient Operating Environment: 0 C to 40 CPower Requirement: 24 Vdc @ 100 mA (through RJ45)Dimensions: 1.73" (4.39 cm) W; 4.11" (10.44 cm) H; 1.62" (4.11 cm) DPackage Type: Cardboard BoxPackage Dimensions: 3.625 x 4.625 x 2.125 in.Shipping Weight: 0.45 lb.WEEE weight: 0.29 lbs.Tariff code: 8543.70.9100
