Brett • 12/17/2019, 2:17:43 PM I accidentally ripped the end off the RCA speaker cable that runs between the two speakers. How do I order a replacement, and is there a longer option than the cable that came with it?
Customer Service • 12/17/2019, 2:17:43 PM
HI Brett: Try contacting customer Service directly and ask for the RMA department. They will be able to help you out. Good luck TL/4599
Joey Resendez • 12/17/2019, 2:17:43 PM Can the speakers work with Yamaha MusicCast?
Customer Service • 12/17/2019, 2:17:43 PM
Hi Joey: According to the Musiccast information I looked at including Owner's Manual for Pre am and main speaker they both Receive and transmit Bluetooth. So as long as you can Transmit as Bluetooth signal from the Musiccast you should have no problem. TL/4712
Deb • 12/17/2019, 2:17:43 PM I have the speaker plugged in and I turned it on. The green light is on. Is the unit charging currently? The owners manual gives no indication of how the speaker charges (does it need to be turned on or does it charge when it is turned off?) or how long it takes before it is charged enough to connect to Bluetooth.
Customer Service • 12/17/2019, 2:17:43 PM
Hi Deb; The BTR 150 comes with a power supply that provides instant full power. It has nothing to due with battery operation. So when the unit lights up your ready to go. Batteries will run down and need to be replaced if you are using Alkaline. If you are trying to use Re chargeable batteries you will have to remove and re charge separately. Note Re chargeable batteries are only 60% of the power of the Alkaline when fully charge so will not give you the same time as a Alkaline.non rechargeable battery life. TL/4721
Greg • 12/17/2019, 2:17:43 PM Can you pair with Echo (Alexa)
Customer Service • 12/17/2019, 2:17:43 PM
Hi Greg: According to AMAZON: Connects to speakers or headphones through Bluetooth or 3.5 mm stereo cable to play music from Amazon Music, Spotify, Pandora, iHeartRadio, and TuneIn. Play music simultaneously across Echo devices and speakers connected via cable with multi-room music. It is referring to connecting with Bluetooth Speakers (BTR150) or Headphones which would feature built in Bluetooth Receiver that should sync up with the dot.. So I am pretty sure it should work, you might want to check with AMAZON to verify how it works. TL/4789
John • 12/17/2019, 2:17:43 PM How do you control the volume?
Customer Service • 12/17/2019, 2:17:43 PM
Hi John: You control the volume on your Bluetooth enabled device. When you sync up you will see your device has a volume up/down that is used to control the volume on most of our Bluetooth speakers. TL/4858
