Our take on the Niles® 12-Volt DC Adapter

Plug this adapter into a switched AC outlet on your receiver or preamp to send component on/off status signals to compatible Niles IR extender systems. See individual IR system pages for compatibility.

This replaced a defective transformer for my MU480. The new transformer and a new MU480 work well.
