More details on the Russound BTA-2

Mark G.

Product Research


Bluetooth A-BUS Module: The BTA-2 is a wall-mounted local input Bluetooth module for the purpose of streaming audio from sources such as smartphones, tablets and computers, etc. with Bluetooth capability, to a Russound A-BUS distribution hub (sold separately).

Bluetooth 4.0 w/ aptX: The Russound BT-A2 incorporates Bluetooth 4.0 with support for wireless audio streaming (A2DP) and wireless audio control (AVRCP). In addition to supporting the standard Bluetooth codec (SBC), the BTA-2 also supports aptX audio encoding for a higher quality audio signal whenever an aptX-enabled Bluetooth device (many Android and Mac computers) is utilized as the music source. The Russound BTA-2 has a wireless Bluetooth range of up to 50' (depending on the surrounding environment and conditions).

  • Whenever a Bluetooth signal is received, the BTA-2 will automatically switch the active audio source to the Bluetooth device, making it simple and easy to use. This local connection will remain until pairing is disconnected or the Bluetooth device is out of range for longer than 3 minutes.
  • The audio output level from Bluetooth enabled devices can vary from brand to brand. The BTA-2 has been adjusted to be equal to the output of most Bluetooth devices; in some cases the level may be higher. Most devices have their own adjustable volume level and it is recommended that this is used to adjust the output level to match the main audio source's volume level.

RJ-45 Connectivity: The BTA-2 is connected to the CAT-5/CAT-6 cable line (no longer than 150') between the Russound A-BUS hub and the Russound A-BUS keypad using RJ-45 connectors. It also can be wired in series with other local input modules along the CAT-5/CAT-6 cable. The local input module closest to the room's Russound A-BUS amplified module, will be the master.

Note: The BTA-2 is connected from its output socket to any A-BUS hub with an input or Expansion Input. It can also be inserted in a main source CAT-5 cable between input module and hub, overriding the main source when paired.

Room Identification: The BTA-2 is identified by an individual code number beginning with the prefix AB (ABxxx). The identification code can be replaced with individual room name identification (eg. Bedroom, Study, Patio, etc,) prior to installation. Visit Russound's website to download the renaming software onto a Windows PC and connect the BTA-2 with the included miniUSB-to-USB cable supplied and follow the on-screen prompts. For installations where more than one BTA-2 is desired, this same Windows software application can be used to custom name each Bluetooth module.

Note: When pairing for the first time, a security code is required. The default code is 1234. The four digit number can be changed or switched off in the room naming software. Individual room naming and discrete security pairing code, must be changed with the renaming software prior to installation.

Mounting Options: The Russound BTA-2 installs easily in a 1-gang box and will also require a decor plate.

Will this work with my CAA66 system?

We have not received any answers from other customers on your question. I would recommend reaching out to an Advisor by phone (1-800-324-9695) or online chat. They should be able to help answer your question.

Does this work with the CAA66 system?
[ Michael  Apr 07, 2020 ]
1 answer
No, this only works with Russound's A-Bus system. Russound has a BSK-1 that will work with any audio system that has pre-amplified inputs. There are many products like the BSK-1 out there, the biggest problem is getting the Bluetooth receiver in range of the room you're looking to use it in. Bluetooth is usually only good for 30ft.

I have a Russound AH-484 hub with 4 A-K3 keypads around the house with each connected to two speakers in the ceiling. How do I connect the BTA-2 to control and come out of all 8 speakers?
