![]() ![]() When the audio source is turned off but the TV Connector is on, the distinctive noise is still quietly audible. In other words, I think it might have helped, but the problem is not resolved… maybe I could tell on an oscilloscope or waveform display. The results from this change were mixed: if there was a change, it’s likely close to the threshold of audible perception. In theory this could contribute to interference as the wireless protocol Phonak’s TV connector uses might not be entirely immune to nearby wifi devices (or conversely, the IoT switch might be poorly designed from an interference perspective). I removed the IoT switch from the power path. The power bar for my home theatre was connected to a wifi IoT switch (used to track power consumption). Second, I considered the power situation again looking for potential sources of noise. This did not resolve the issue, so I switched back. I am on the verge of seeking a replacement under warranty via my audiologist but wanted to check/report this here both to potentially benefit from others’ experience as well as to share my experience with others.įirst, I switched to analog input instead of optical (feeding from the headphone out of my reciever). Also, no such noise is evident in the audio output from the 5.1 speakers so I don’t think it’s an issue with the TV. It might be electrical noise (I need to try powering the TV connector from a USB power bank to eliminate this possibility). I can’t eliminate it by taking the splitter out of the signal path or by trying another optical cable. This isn’t present with my other Phonak accessories, with Bluetooth, or at other times using my HAs. However, I am noticing some annoying digital compression (or some other kind of noise, perhaps related to the wireless protocol) that seems to me coming from the streamer when the TV sound is quiet or silent. Actually, that’s a huge understatement… I’m amazed by how great it is and will always want this type of accessory in the future. ![]() Now that the splitter has arrived, I’m pleased with the results. Other HA brands have a pass-through optical port to provide this feature built-in but Phonak appears to have prioritized making the smallest possible device. It took me a while to start using my Phonak TV Connector, as I needed a toslink (fibre optic) splitter to ensure audio goes to both the streamer and to our existing home theatre audio system. ![]()
