Pairing a Sound Bar to a Bass Module
Overview
The sound bar RF ID is stored in the bass module. Once the RF ID is stored, the sound bar will only communicate to the bass module it has been paired with. If you are testing a customer soundbar or bass module with a test soundbar or bass module, it is necessary to pair the customer device to the bench test device. If you pair a customer soundbar or bass module to a test device, provide the customer instructions to pair their system when returned. A maximum of four paired sound bar and bass modules can operate in close proximity.
Wired Connection
If using in an application such as a hotel or areas where RF interference might occur, a SMB wired connection should be used. When using the wired connection, the sound bar will pair automatically with the bass module. 331731-0010 : 4 meter SMB to SMB Coax Cable (used for end user wired connection) 345328-0010 : 1 meter SMB to F Coax Cable (two used for wiring up to 100’)
1. CineMate 1SR End User Pairing Instructions
1.1 Unplug the Acoustimass module AC power cord.
1.2 Remove the door on the end of the speaker array.
1.3 Press and hold the ADAPTiQ button for 3-4 seconds until the status indicator starts slowly blinking orange.
1.4 Plug the Acoustimass module AC power cord in the AC outlet.
Pairing is complete when the Acoustimass module status indicator becomes solid orange and the speaker array status indicator turns off.
2. Lifestyle 135 End User Pairing Instructions.
2.1 Using the system cable, connect the soundbar to the control console.
2.2 Apply power to the console, soundbar, and bass module.
2.3 Press the Setup button on the control console and select the “Reconnect Acoustimass” menu item..
3. Pairing using a SMB cable
3.1 Connect SMB cable, part number 331731-0010, to the sound bar and bass module.
3.2 Connect power to the soundbar and bass module.
3.3 A solid orange LED on the bass module indicates paring is complete.
3.4 To avoid the soundbar or bass module from pairing with another system in the repair area, remove power from both components before removing the SMB cable.
Setting The Region Variant – CineMate 1SR Only
1. Setting the Region Variant - CineMate 1SR Only
There are 4 variants of the CineMate 1 SR sound bar (US/AIM, EURO/UK, Asia Pacific, Japan) that have separate AdaptiQ language lists. When replacing DSP PCB in a US, Asia/PAC, and Japan variant, the variant needs to be set to present the proper AdaptiQ language selection list. The UK/EURO variant does not need to be set. The US, Asia/PAC, and Japan version use the same version of a programmed IC containing the language list. The EU/UK version uses a programmed IC that contains just the EU/UK langue list.
1.1 Issue TAP commands.
1.2 Enter the TAP command TN 65 ON, to turn on the sound bar.
1.3 Enter the appropriate TAP command from the table below to set the variant
US TN 33 1
Asia/Pac TN 33 3
Japan TN 33 4

2.3 Sweep the audio generator form 200 Hz to 2 kHz.
2.4 Listen for buzz, rub, or extraneous sounds.
Localize and repair any buzz. Replace any transducer that rubs or produces extraneous sounds.
2.5 Issue the TAP command VO CB 20 to set the volume level.
