Question: How many devices can it pair with Simultaneously?
Document: Connect the RCA cables to an audio input in the receiver and plug in the power and you are ready to go. To pair a device press the button on the front of the adapter and turn on blue-tooth on your device. Then just tap on the name of the adapter and you're ready. We've been able to stream music from TuneIn, Rhapsody and files from throughout the house (1100 sq ft) including upstairs. There is some skipping but we've noticed a difference depending upon the device used. Our iOS devices never skip and our android often skip quite a bit.
Everyone knows that the biggest problem with Bluetooth speaker systems is that the range is often too short. Go to another room with your device and often you find you lose your connection and are forced to re-pair your device. The Amped Wireless Speaker Adaptor looks to solve that dilemma by proving you with an antenna that will amplify the Bluetooth signal to double your range. It&#8217;s quite simple to use; just plug in the adaptor to your stereo system or speaker with the included cable and pair up your device.
This device worked well with my Android tablet- decent range and sounded fine, but did suffer some drop-off issues every 15 minutes or so where there was a few seconds of audio on and off. In comparison to being plugged in, it seemed like some mid to low end frequencies were missing when streaming over bluetooth.I spent quite a bit of time trying to get it to work with my Windows 7 computer. I was able to pair it, but not stream audio. The instructions included in the package and referenced on the support site are only for Windows 8.
Set this up, paired my Motorola Droid Razr Maxx, played music. Till I went to change the volume on my phone the audio cut out. Pause the song and hit play again, audio would only come through very faint regardless of volume level set on the phone. Only way I could get it to play again was to un-pair and re-pair. GS4 worked flawlessly, so did an iPhone5. iPhone4S couldn't find the device to pair. Called tech support, was told to return the device and get a new one.
Great BT audio receiver! Connects instantly with paired devices within range. I use it most often to transmit from my iPod, tablet or laptop to my home audio system. Excellent product!
If you want it to work with another device, it may or may not work. It definitely does not like working with my HP and Apple computers. I have to presume that contrary to statements on the website to the contrary, this unit is not fully compatible with all Bluetooth standards.For what it is worth, my laptops connect and work just fine with several other Bluetooth devices including Sennheiser and Bose.
I have tried other units from Logitech, Belkin, etc. They all sucked. This one works!I have this unit sitting in my media closet on the first floor of my house. It is connected to a Russound media controller for whole house audio. I can stream from my laptop, tablets, phones, etc with ZERO dropout from any room in the house including the 2nd floor and the basement!The BT setup was a snap and automatically reconnects when entering the house.The device shows up in the list of BT devices as &#34;Amped BTSA1 F09.&#34;  While you cannot rename the device, I have confirmed with Amped that the devices have different name suffixes.
The Amped Wireless Adapter did ok for about 40' away which was okay but not as good as the Miccus. One additional note (which was the deal breaker for me...FOR WHICH I COULD NOT GET A GOOD EXPLANATION FOR...even after calling Amped Customer Service). The Miccus worked great with all devices...The Amped worked fine with my wifes phone (Blu Life View & my Samsung Tab3 7.0 but I could not control the volume with my Motorola RAZR Maxx..(It would either go from mute or low volume..when you raised the volume rocker with the phone it made no difference....even though the range was already better with the Miccus this bugged me & I wanted to find an explanation...NEVER FOUND IT....The Miccus works superb...easy choice for me!
The unit includes both 3.5mm audio and RCA outputs which is very convenient. I had it up and running and playing music in just a couple of minutes. It really is that easy!I had no problem taking my phone into another room, down in the basement, and even out on the back patio without dropping my connection. Granted all of those ranges have been within 40 &#8211; 50 feet but it&#8217;s still nice as I have had many Bluetooth speakers that will drop when in the same room.
UPDATE: 21 April 2014I contacted Amped Technical Support via e-mail and they had me return the unit to them. Of course, it was at my own expense and they recommend that I have tracking since they are not responsible for any returned items that do not show up. It took me a couple of times to get an RMA from them, but I finally got one and I returned the unit ($12). They sent out a new unit to replace the one I sent in and this one appears to work.
Answer: This unit can only be piared/connected to one source at a time.
