Product Description
RDL RU-BTLA Bluetooth® Line-Level Audio & Format-A Interface
Overview
The RU-BTLA is a Bluetooth audio receiving module with three sets of audio outputs: Balanced line-level XLR jacks, unbalanced
line-level RCA phono jacks, and RDL® Format-A twisted pair RJ45s. Format-A outputs are at a fixed level and may be configured mono or stereo on a recessed front-panel slide switch. The line-level outputs are all controlled by a single adjustable LEVEL attenuator on the front panel, configured mono or stereo on a recessed front-panel slide switch. All outputs may be used simultaneously. The RU-BTLA features studio-quality circuits and analog filters to provide audio performance exceeding expectations from consumer interface technologies.
Pairing is initiated by a front-panel pushbutton. Pairing status is displayed on associated LEDs. A rear-panel terminal block allows the RU-BTLA pairing functions and status to be remote controlled by one or two separately available RDL remote controls. Pairing may be remotely initiated by dry contact closure.
The RU-BTLA can be sequentially paired with an unlimited number of Bluetooth devices. The most recently paired seven devices are retained in memory for re-pairing. Upon pairing to a new device, the oldest stored device is automatically deleted.
When paired with a compatible Bluetooth-enabled device, the module receives stereo audio from the Bluetooth source. The stereo Bluetooth audio feeds the line outputs. The stereo signal is also sent through two Format-A pairs to any RDL Format-A receiver (available separately). 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. All audio outputs are muted when the RU-BTLA is not paired.
With stereo operation selected, an additional Format-A source (set to Pair A) may be daisy chained with the RU-BTLA to a three-pair Format-A receiver. With mono operation selected, up to three RU-BTLA modules may be daisy chained to a single three-pair Format-A receiver. Connections between Format-A modules use standard CATx cable with RJ45 connectors.
The RU-BTLA modules may be powered from a Format-A receiver or from an external 24 Vdc power supply (available separately). When external power is applied to the RU-BTLA, power is sent out the Format-A jacks to other connected devices. The installer can customize the module name and programming password through the Bluetooth connection using a smartphone, computer or tablet terminal program. The RU-BTLA was designed to support the unique requirements of commercial installations, including the ability to enable/disable PIN pairing, define the pairing PIN and customize the broadcast name of each RU-BTLA.
Configuration is straightforward using RDL Console 3 (available at rdlnet.com) which communicates with the RU-BTLA over Bluetooth. PIN pairing support has been verified on Apple, Samsung and Windows 10 devices. Support for this feature on other devices is dependent upon implementation by the respective device manufacturers and cannot be guaranteed by RDL.
High performance, simplicity of operation and efficiency of installation make RDL the best value in professional Bluetooth interfaces.
