Reviews

Rolls HE18 Buzz Off Hum Eliminator Balanced/Unbalanced Converter
Rolls HE18 Buzz Off Hum Eliminator Balanced/Unbalanced Converter is rated 5.0 out of 5 by 1.
Rated 5 out of 5 by 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.

Rolls HE18 Buzz Off Hum Eliminator Balanced/Unbalanced Converter

Hi in my karaoke system my mic keep having feedback is this my solution and how do i hook it up to elimator the feedback.thank you

Asked by: Phong
No this will not help with feedback, this only helps with ground a signal humming issues. You will need an actual feedback destroyer, we have quite a few available. For the price, the Behringer Shark model is probably your best bet.http://www.parts-express.com/behringer-fbq100-shark-automatic-feedback-destroyer--248-6676
