GFB Whistling Trumpet (suits all valves)The 5702 can be used in place of the standard trumpet on all GFB valves, and will make the whistling sound more readily than the 5701 (high boost and RPM is required to get the whistle from a 5701), and at a slightly higher pitch.? Like the 5701 however, it is necessary to run the valve so that all (or most) of the air vents through the trumpet ? Respons valves will typically not generate the velocity required to whistle when set to 50 50 venting.

I added a center channel speaker, and it was partially blocking the remote sensor. This solution works like a charm and has an easy setup. One end points towards the existing IR, and the other end goes where you are going to point the remote to. The only suggestion is to include a USB connector with the product, so I don't need to find one.

Very good signal repeater

Style: 1 to 1 IR Repeater

Fantastic product! I have a center channel for my surround sound that blocks the infrared sensor on my Sony Bravia TV that never works. I always have to get up to turn the TV on or off as well as other functions. So I purchased this product and it worked like a charm. Very simple to install, took less than 5 minutes . I didn’t have no compatibility issues. It was plugged play . Simply stick on the transmitting sensor by the receiving sensor on the TV and then the extended sensor for receiving from your remote control put where you would like it, lastly plug in the USB plug into any 5V power block and you’re done. Now I have no issues with range with controlling my TV, which is great.!👏🏼. Definitely a good product. I would highly recommend…

Easy to Set up

Style: 1 to 1 IR Repeater

Works great. Have Sonos playbar mounted behind TV and it does not support eARC, only IR, for use with AppleTV remote. This solved problem.

Works just as advertised!

Style: 1 to 1 IR Repeater

Super east to set up. Haven't had any issues in our very long living room so it must work at around 25ft
