Review on Wireless Audio Transmitter for Smart TVs - WiSA SoundSend | 8 Channels Uncompressed 24-bit 48/96 kHz Sound | Auto-connects to WiSA-Certified Speakers (Sold Separately) by Kartik Starks

I'm one of the first users of this technology. I'm also a retired engineer. I have worked with WISA to fix issues with the earliest devices and the product has continued to improve. Many more features are planned and in development. As with many wireless devices, there is a delay of approximately ½ second when first starting a streaming source or when changing streaming sources. The device must recognize the format (Bitstream, Dolby Digital, Dolby Atmos, etc.), apply the correct decoder to the stream, and sync the stream to all speakers. There is a handshake that happens to any speaker whose receiver contains a manufacturer information table telling it what it wants in its data stream. All of this takes time to process. If the source is interrupted, e.g. B. When a Netflix stream is paused due to Wi-Fi issues between the TV and router, it takes about 1/2 second to receive sound after the stream resumes. After establishing a constant stream from the TV, not a single speaker turned off. I started testing with the Platin Monaco this January and I bought SoundSend to use with Klipsch speakers when I returned the Platin Monaco system (I didn't like the sound of the speakers from the small speakers but the device worked). Good). I have worked with WISA across multiple updates in both the IOS app and device firmware and have seen continuous improvements with new features. I also tested the Klipsch RP-Hub1, the Enclave transmitter and the Axiim Q-UHD. They all worked well with the latest firmware from each vendor, but the SoundSend is best supported by continuous improvements, the only one to support eARC and it's the most cost-effective device. In fact, I was so impressed with this technology that I decided to design a standalone receiver for use with powered speakers and a monoblock amplifier with built-in receiver for use with high-end passive speakers. I built a receiver prototype and 3 different amplifier prototypes. High quality 250W 4 ohm monoblock with Hypex Ncore amplifier. I've added some photos for your enjoyment. They are not ready for the market yet, as I still have to do more tests and the final packaging is not yet complete. I also have a smaller 30 watt unit that velcro attaches to the back of the speaker. the speakers I wanted in my system. There are no prices or units available for sale. My goal is somewhere in the next 2-3 months. Rest assured I would not have poured thousands of dollars of my retirement savings into this project if the technology wasn't reliable and the best audiophile quality available. a few words about the wireless environment. Where you place the transmitter is important. This is a high frequency radio frequency signal, so placing it behind a television or metal structure can weaken the signal. If it finds that it has lost connection to the speaker, it will try to reconnect until it is successful. This is the only dropout source anyone should ever come across. The speakers must be within 30 feet of the transmitter. While it can work with speakers in another room, dropouts are possible if the signal needs to be routed through walls. My farthest speaker in the test is 25 feet from the transmitter. My transmitter isn't in an ideal location (it's on the floor in my ship's clad fireplace) and I haven't had a signal drop out in 6 months. I hope this review helps you. UPDATE: I've had a chance to test version 2.6 now and it fixes some if not all of the complaints posted. Audio start delay when switching sources is now 5-10ms compared to 500-1000ms before. This is a big improvement. I haven't had any issues so far and will keep updating this review as I've had more time to test it further. Update 7/7: There is now another firmware update, version 2.7. This update fixes an issue where your TV only supports ARC (not eARC) and you are using Dolby Digital and Dolby Atmos. The company continuously improves the product. I spoke to the product manager and they are constantly adding features and additional improvements. WISA is used by a growing number of high-end audiophile companies due to its many additional features and capabilities, especially when compared to WiFi or Bluetooth wireless systems.
