    Rick • 12/17/2019, 2:17:43 PM I have 2 pairs of the WR150 in my backyard. However, one of the pairs has failed. Since there speakers are no longer available, I'm looking to upgrade to the BTR150 Bluetooth speakers. Like I mentioned above, I have 4 speakers total being controlled with a single remote and module. How will this work with Bluetooth speakers? I have a large backyard and require 4 speakers!

    Hi Rick: Unlike the Wireless versions which can have both pair of speakers be driven by a single transmitter the BTR speakers can only sync up with a single pair at a time unless you have one of the newer smartphones which sync up to two receivers at once. What you might consider is purchasing our new BOM4.1 which features our OM SUB 200 8.0" Outdoor Powered sub woofer with an internal 4.1 amplifier with four powered output wires so you can drive 2 pair of speakers. You could use the 2 satellite speakers from your current WR-150 rock speakers (the ones connected to each of the master rock speakers by speaker wire). I am assuming the receiver is no longer working in one of your master rock speaker but the satellite should still be good.You can purchase a pair of RX150 rock speakers and connect them as the second pair. This would give you the two pair plus a complimentary sub woofer for better fill for your back yard. That would give you your two pair matching the WR150 plus adding an 8.0" sub. Let me know if you need further clarification. TL/4974
    Bill • 12/17/2019, 2:17:43 PM Just purchased your rock speakers from Australia, can I plug it straight into our 240 volt outlets and if not can you advise if I need an adaptor of some sort. Regards Bill
    Customer Service • 12/17/2019, 2:17:43 PM
    Hi Bill: The power supply is multi voltage 110V to 240V so should be no problem. TL/4894
    Sam Barney • 12/17/2019, 2:17:43 PM I just received the BTR150 Bluetooth speakers and have them connected to a Yahama RX-670. The problem I have is, there is no volume control on the speakers through the Yahama unit. Any ideas as to what the problem may be? FYI my order number is 275315. Thanks, Sam
    Customer Service • 12/17/2019, 2:17:43 PM
    Hi Sam: The volume level is controlled by the Bluetooth enabled device (the source). In this case, you need to make sure you have the Bluetooth Transmitter enabled in the Yamaha and then you should be able to control the volume at the Yamaha Receiver (maybe with the remote control for the Yamaha). Try connecting the BTR1500 with your smartphone to certify they work. If they work with the smartphone than it is an issue with the Yamaha. And I believe the Yamaha has both a Transmitter and Receiver option depending on your application. TL/4982
    Linda • 12/17/2019, 2:17:43 PM How many batteries do they take?
    Customer Service • 12/17/2019, 2:17:43 PM
    Hi Linda: These are AC powered only from the waterproof Power Supply that comes with the unit, and around 20 plus feet of connecting cord. There is also a 25-foot speaker wire included which connects the master speaker to the passive Satellite Speaker. The Master Speaker has the built-in Bluetooth Receiver and Power Amplifier. The previous version of the BTR150 had a Battery option. Sorry about that... TL/5049
    Ron • 12/17/2019, 2:17:43 PM Are these speakers truly wireless
    Customer Service • 12/17/2019, 2:17:43 PM
    HI Ron: All of our Bluetooth outdoor speakers consist of a master and satellite speaker. The Master speaker has an AC Power cord connected to it to power both the Bluetooth Receiver and 2 Channel Digital Power Amplifier. One of the channels is connected to the internal speaker of the master unit. The second channel is connected to the Satellit unit by a two conductor speaker wire (+/-). Technically the only wireless connection is between the Bluetooth enabled device and the Bluetooth Receiver built into the Master unit (either Rock, Frog, Planter or Patio speaker). The limitation to these kits was the fact you could only sync up to one pair at a time so you could not add a second matching pair. That is why we created the BOM4.1 which is an outdoor subwoofer with built-in Bluetooth Receiver and 100-watt amplifier for the internal sub and four 60 watt amps to power any two stereo pairs of speakers. Not only you now can have two pairs of speakers but have a subwoofer to boot connected to Bluetooth, you guessed it... wirelessly. TL/5051
