    What's on your mind?

    Bob • 12/17/2019, 2:17:43 PM I have a 3-4year old audio receiver that is hardwired to the 2 speakers mounted over a deck. The receiver is blue tooth enabled and works well while sending music to it via blue tooth cell phone. My question is, will there be a problem running the wireless Bluetooth rock speakers as an extra pair of speakers at the back of the yard? Distance about 40-50 feet from the receiver that is in the house behind the wall facing the back yard where the wireless speakers will be placed. Will the wireless speakers sync well enough to blend in with the hardwired speakers, ie no delay in the sound to the wireless speakers?

    HI Bob: The way Bluetooth works with our Bluetooth speakers it syncs up with a Bluetooth enabled device. Your device will only sync up with one receiver at a time so it would sync up with either the Bluetooth enabled Receiver you have or the BTR-150 but not both at the same time. The only solution is to hard wire a pair of Rock speakers to your Bluetooth enabled Receiver which I am assuming has the ability to drive a couple pair of speakers. Most of our Bluetooth Rock and patio speakers work the same way where you have main/sync speaker that has the built in Bluetooth Receiver and stereo power amplifier. The second or satellite speaker is hardwired from the Main/sync speaker with the speaker wire that is included in the kit. Note: You will also have to run AC power to the main/sync speaker to power both the Bluetooth Receiver and Stereo amplifier. The only true wireless signal is between the Bluetooth enabled device and the Main/sync speaker. So if you are able to hard wire another pair of speakers to your existing Receiver you will have many more choices of either rock, patio or omni speakers. And you will be able to connect more than a pair to your Bluetooth enabled Receiver. I hope that helps TL/3826
    Rich • 12/17/2019, 2:17:43 PM How long is the plug in cord on the main speaker?
    Customer Service • 12/17/2019, 2:17:43 PM
    Hi Rich: Both the BTR-150 and BTF-525 (frogs) have the same Power Supply where the AC plug is part of the module. The cord is 26 feet from the Power Supply module that plugs into the AC outlet. TL/3868
    phil • 12/17/2019, 2:17:43 PM How long is the wire from the power supply box to the first speaker?
    Customer Service • 12/17/2019, 2:17:43 PM
    Hi Phil: On the BTR-150 The power Supply block plugs directly into your AC outlet; it has a power cord that is 25 feet long that you plug into master speaker. The speaker wire which is terminated at both ends(with an RCA connector) is just under 13 feet long. We recommend placing the speakers 8 to 12 feet apart for proper stereo separation. TL/3900
    Lawson • 12/17/2019, 2:17:43 PM How long does the battery life last
    Customer Service • 12/17/2019, 2:17:43 PM
    HI Lawson: We have used AA Lithium Ion batteries powering our BTR150 for three days (playing about 8.5 hours during the day) in the offices. Lithium may last 2x longer than Alkaline batteries. TL/3958
    Dick • 12/17/2019, 2:17:43 PM If using batteries, do you need to turn the unit off when not in use...or does it go to a hibernate default if not in use?
    Customer Service • 12/17/2019, 2:17:43 PM
    Hi Dick: We would suggest when using battery power versus hard wire you should turn off the unit when not playing music. TL/4018
