HerfairLINGLING ONE IR Receiver Cable – 10FTInfrared Remote Control Extender Repeater Cable with 3.5mm Jack Plug for HD DVR Cisco Explorer Verizon FiOS and Other STB Set Top Boxes - 2 Pack

I have a Russound TVA2.1 amplifier fed by optical output from the TV. The original IR receiver stopped working. Could get this next day and it has the same plug configuration. Thought it would be a winner. But, it's not working either. The amp works "except" I cannot adjust volume.Will search for something else. Maybe call the OEM.UPDATE: HERFAIR contacted me due to return. Top notch! I have found my problem is likely the receiver, not the IR receptor. I changed rating from 1 to 5 due to their outreach and the problem isn't with their product.

This IR remote sensor works very well by connecting and pluging to the IR In Port of the Tonewinner AT-300 AV Preamp Processor. It is very sensitive and functions well to the IR remote control in the 7.2.4 Home Theater.Highly recommended to buy.

Entra muy bien y recibe a la perfeccionla orden del control remoto

This is the one you want for the Micca Speck 4k Ultra. It's much more sensitive than the internal sensor. The remote doesn't have to be pointed exactly at the Micca box as before. With the remote sensor just sitting on top of the TV stand, you can point the remote at any wall or ceiling and it works perfectly. When I first got my Micca Speck 4k Ultra, I thought I had slow or no response problems. This all cleared up after plugging in the remote sensor.

Love em'. Do exactly what you want. The cables is better quality than the one that came with my old Motorola DVR. A Plus.
