This Bluetooth XL transmitter is great for if you don’t need to have absolute simultaneous low latency connection to a speaker. Admittedly, this is a rare use case but occasionally this could be true for someone like a DJ or just someone who’s trying to amp up some music at a party or some such type of activity.
Beware, though, if you want this for singing in a live scenario, it is a Bluetooth device with all of the latency at that implies. There will be a noticeable lag between the time when you speak into the microphone and when it comes out of the speakers. The seller is quite upfront about this in the listing though, so I can’t take a point off for this. This is exactly what the device says that it is.
As a complete technical kindergartner, I found this blafili Bicast bluetooth transmitter very intuitive to set up and connect - I simply plugged in it with the provided USB-C cable and it instantly connected with the bluetooth speaker.
Eliminating the need to be connected to whatever output you want to transmit from, you only need to connect this transmitter to your mixing desk or PA system with the XLR connector or your laptop, tablet etc with the USB-C cable, and you can bluetooth audio direct to your speaker or headphones - this is amazing to me as i already mentioned i am “ahem” technologically challenged.
You can see the status and battery levels with the clear LED display, and the battery life seems solid. I was really hoping to use this to connect my bedroom digital TV to a bluetooth speaker, as the audio jack is failing and the TV is not bluetooth enabled. Unfortunately being a not-so-smart TV, while the transmitter and my Bluetooth speaker talked to each other and connected with no issue, I can’t get the TV to talk. This is 100% the TV’s fault. Apparently the multiple high-end codecs should be my way around this so i’m confident one of my techie friends will be able to sort this for me, it’s portable which is another tick ✅ so I’ve already had them confirm it’s an excellent product.
Review from AmazonThis filled a gap I didn't even realise existed. Being able to add Bluetooth to gear with XLR output makes it surprisingly versatile, whether it's a mixer, PA system or other audio equipment. Pairing was straightforward, the connection stayed stable, and the sound quality was better than I expected. The battery also lasted through a long listening session without needing a recharge. It does have a delay, depending on the system you attach it to, but that's to be expected.
Review from AmazonThis Blafili Bicast Bluetooth Transmitter is great!
I've been using the Bicast Bluetooth transmitter with my mixer, and overall it's been a great addition to my setup. The XLR input is what sold me, as it's much more suited to mixers and PA gear than the usual consumer Bluetooth adapters.
Once everything was paired, the audio quality was excellent. The connection has been stable, and being able to stream to two Bluetooth speakers at the same time is really handy. We have had this plugged into our mixer and the cast can connect their device for warm ups and have their music through the system!
The battery life has also been impressive, easily lasting through long sessions without needing a recharge. Also recharge is easy with the supplied USB C cable.
Unit is relatively compact so easy to put in with your tools or bag when travelling.The only reason I'm giving it four stars instead of five is that the initial setup took a little patience. Pairing wasn't difficult, but getting everything connected properly especially with two speakers took a couple of attempts, and the instructions could be clearer.
After that initial learning curve though, it's been reliable and does exactly what it's designed to do. It's a really capable little transmitter that makes wireless audio much more convenient. Would recommend 4 Stars!
The new Bi-Cast is a versatile tool from Blafili. This device allows you to connect two Bluetooth receivers to a single transmitter. Depending on what you are needing to do with the venues, this can link multiple Bluetooth speakers or receivers. I have included a video that helps explain function, features, and expectations. The sound quality is great, the battery life is quite extensive at 6 hours, and it is extremely easy to use!
