ALTOBluetooth Ultimate - XLR Equipped Rechargeable Stereo Bluetooth Receiver For Mixing Desk / Audio Mixer Setups and Active PA Systems

First, I would like to address buying a used product from Amazon. I purchased the Alto Ultimate with the condition described as: "Used - Very Good. Item will come in original packaging. Packaging will be damaged."I received a large cardboard box with a small clear plastic baggie containing the Alto. Nothing else except for paper padding. No charging cord, no instructions. By the time I purchased a charge cord I saved a whopping $4 USD. Whoopie!Now on to the product review.... I am an audio professional, with over 40 years of TV broadcast and sound reinforcement experience. I will not bore you with response and distortion specs. This is not a straight wire. It does color the audio. If the intended use involves an area with 500 people, each with a cell phone, then you had better have a backup plan.So what can it do? Well if a performer wants to play tracks from a laptop controlled by the drummer, then that can be set up wirelessly in about a minute. How about a church "Kid-Fest" with a bouncy castle and other activities? You want sound from speakers that cover the area but don't want a bunch of XLR cables that have to be taped down.Specifically, a non-critical activity where you can use very good audio with a bit of latency. I really like having a couple of these in my tool box for a quicker setup and strike.My wish list: Wish there was a clipping LED to make setup even easier. And a way to turn off that ridiculous signal loss beep.In summary, the sound is very good and works great in many situations. Just have an XLR cable ready just in case.

Am a DJ and a bunch of times I just rent out my speaker on it’s own but it’s not Bluetooth it’s just a rcf art 912a speaker so I got this and plugged it into the speaker and it works great easy to use and he sound quality is great I didn’t experience any issues with this so now I rent out my equipment with this it does feel a little junky material but it still works and it’s decently bigger then expected and the only downside is that if you have the volume on the speaker and you disconnect from the device it makes a very loud beeping sound so make sure to have the volume to the lowest then once it’s connected plug it into the speaker but overall works great and does the job for me

A friend had the mono version of this and let me use it to play a track from my phone at a special church service one evening. After this, I just had to have one. I decided on the upgraded version and I have been very happy with it. I use it quite often and have never had an issue. It's very handy for practicing... I can play a track from my phone without needing anyone there running the sound. I can back up and repeat as needed right from the phone. Great little gadget for anyone who needs to get sound from their phone or tablet into the sound system. It's really great when visiting a different church where you are unsure of their sound system capabilities for tracks. You can just plug this into an open XLR jack, do a quick volume check, and you're good to go. Love it!

I have a nice sized basement that doubles as a band room and Karaoke club. So my sound for Karaoke normally runs from my computer through a scarlet solo to XLR into my board. Very little EQ required for nice thumping sound.My goal was to reduce cords required for the Karaoke setup since a lot more people are involved. But I didn’t want to sacrifice sound quality.I tested the sound back and forth between the corded setup and this (going through my board/mixer).Results:Surprisingly good. Some EQ’ing IS needed to get you where you want to be - and most others probably won’t notice the difference (depending on your FOH setup). But the alto comes across a little thin on the bottom end.If you’re an audiophile, you’ll probably want something else, or stay corded. But for everyone else you’ll think this is great.No dropouts. Clean sound.Drop the high frequencies a little. Boost the low end. Subwoofer helps.

So far it’s great. Bluetooth connect everytime and fast charging. Sound quality was awesome no hissing noise it’s as silence as connecting to the wire. Just be sure to turn down the volume or off when you’re disconnecting from your phone cause you’ll hear beeping noise it’s looking for Bluetooth connection. This don’t bother me. All I care was sound quality coming out from my PA system and this thing delivered it. I’ve tried the On Stage and Xvive I returned them both, no good! If you are looking for a Bluetooth connection for your equipment this is it and look no further. I highly recommended this product.

Very good product. Have used quite a a bit with great ease and no problems whatsoever.

I have tried many bluetooth MP3 and this one is the best I have spend over $300 on some and this one has better range and is easier to use also. I have 3 of these already. I have tried to contact manufacturer once but I got no response (due to an older model giving me problems) but honestly the best. I use it professionally 3-4 a week for big and small venues

Use this many times works great
