Rated 5 out of 5
from Quality product that works greatI had a 60Hz hum from one of the power amplifiers in in my home studio. After trying numerous fixes that did not help I decided to buy the HE18. It worked as advertised. The hum is completely gone. The unit is very easy to hook up. It did not otherwise negatively affect the audio quality. The HE18 will also convert between balanced and unbalanced lines. Product quality is very good and it is manufactured in the USA. The HE18 uses 1:1 isolation transformers to electrically isolate the input and output on each channel.
