It’s freaking 2010 and we’re still using IR, WTF? Oh well… if you are looking to find the most reliable IR Sensor to connect to your IR connection block (used in applications where you want to put AV components in a remote area but still have control), I highly recommend the new Niles MS220. I have used different units by Xantech, Russound, even Niles and the MS220 is the most reliable. How do I know? For starters, all the others I have used you needed to choose between CFL/Plasma friendly and not. You’d get weird noise (the LED on the sensor would flash) from stray “IR” signals. The MS220 utilizes a “smart” electronic circuit to filter out noise and works with all IR formats. Check out Niles Audio for more information.
