Klark TeknikAIR LINK DW 20R 2.4 GHz Wireless Stereo Receiver for High-Performance Stereo Audio Broadcasting

UPDATE 4/2025:I now own 2 receivers and a 1 transmitter, and these things work really well together. The stated range is 100ft. Indoors, through walls, you will get less and human bodies absorb a lot of RF. That said, I tested these units with an open line of sight and the reliable range was 230 ft, with the signal breaking up at 265 ft! Not bad for 16 milliwatts (12 dbm)I went ahead and modified all three units with BNC jacks and external antennas. With 6 dbi monopoles, range was roughly the same, 9 dbi monopoles added another 30 ft of usable distance. Switching to a pair of 18 dbi gain Yagi-Uda antennas range jumped to an incredible 1150 ft of solid signal, 1175 ft was the limit with some obstructions. 1250 ft feels possible, but anything over 1000 ft is just great. Maybe Klark can provide a factory external antenna option.ORIGINAL REVIEW: Not sure why this unit is getting bad reviews. I own two and the matching transmitter, and they work perfect. Pairing was stupid easy and I only needed to do it once. I feed 3 speaker systems at a time, one directly and two from these receivers. There is no perceivable delay in the signal to the wireless units.Range is stated as 100 ft and you won't get much further than this line-of-site. Walls and metallic objects attenuate the signal, but this is nothing new for a radio pair. I mount these units up high to keep bodies from diminishing the signal. Honestly it would be great if they used SMA jacks for the antennas so you could fit your only high-gain directional antennas. I planning to mod mine this way to gain some range.Audio quality is great and not distinguishable from a wired balanced cable. Having balanced and unbalanced connectors on the same unit eliminates the need for a separate DI box in the change.

I ready try it wt More of 10 devices. And not even show it in the Bluetooth devices in Apple, or PCs… a complete disaster! Follow every single instruction step by step and nothing. Connectivity 0 of 10

Works well for what we needed. We needed something to connect bluetooth to to play audio as any wiring was visible and our console is in a back room. functions well for about 40-50 ft range behind a wall. sound quality is good with no noticeable lag. You can only connect 1 device to it at a time. Overall, great product.

This unit is a scarce commodity, very hard to find in stock anywhere! I was glad I found it and the seller shipped instantly. It arrived in perfect shape. I would receommend this bluetooth receiver to anyone looking for this kind of connectivity. The Klark Tekink brand makes excellent products and designs them to function well and take a beating if they happen to get dropped. Excellent choice.

I had high hopes for these devices. The large antenna in particular looked very promising. I felt sure that this substantial rugged looking system would outperform the other options. I rely on wireless solutions on stage (generally using Sennheiser products but I’ve used most of them), and thought this product would be a good choice for a 2.4GHz link without batteries. Unfortunately, I find that the range is poor. I can stand next to this device where it’s cutting out, yet at that position my Sennheiser wireless is still operating perfectly. Also, these units have much more latency than I expected. I somehow missed noting that detail in the specs. So basically I now have a solution that is of only marginal utility. I can’t place the gear where it should go from a performance standpoint; I need to put it where coverage is possible, which seems to be nearby and line-of-sight. Oh well. The price wasn’t bad anyway. I’m posting this review on both transmitter and receiver since they’re sold separately.

I am sure the product will do what they say. The problem is that it only looks exactly like what I want… which is to play music from my phone or tablet through a powered pa without using a board. It will not do this, I have just learned. But there are products that do. They look just like this one.

Worked great, no interference with the wireless mics or anything. Just make sure you buy the same ones! (I messed up and purchased a BT receiver and 2.4gh transmitter first so clearly I'm a novist).

This product does not connect to a Bluetooth source such as a cellphone. This receiver only accepts signal from a a Technix transmitter which would need to be hard wired to an audio source. Amazon Refund process gets 5 stars though.
