Removes the hum!

By Julian
Rated 5 out of 5
Date: 2024-07-19

I've used this device on an older Tascam recorder and simply put - this devices removes the hum that it produced and now I'm able to use the recorder with confidence. This set up is very simple. It serves as the middleman between the mic and the recorder and/or device being used. On top of it being a small devices it's also all metal which feels rugged like it can take many years of use and still thrive. Also, it does not require power - which is a plus. If you have a device that has a hum, this transform will remove the hum while also not taking up too much space if you're a mobile filmmaker like me.

Did the job for me

I have a home recording studio and there is a synth (Korg 01/WFD from the 1990’s) that always gives me a slight hum noise. The humming is faintly low but enough to bother me, especially if I’m recording; for example, if I’m just playing the piano nice and mellow, instead of an entire sequencer with multi tracks in a song, I can still hear that hum. I have a small Mackie mixer, nothing fancy, but it’s very sonically clean as far as audio output. Connecting the XIT-600 in the mixer’s XLR output solved that annoyance on that particular scenario and now that hum background noise is gone and took care of 1 channel. I only have one of these. Now I need to get a second XIT-600 as I record in Stereo. I also recorded / tested the output audio from my mixer to a Tascam DR100 MKII and a professional field recorder such as the Sound Devices Mix Pre-6, which is an unit that is utilized by many boom operators to record audio in many movies. If you deal with more pronounced hum or ground looping issues, since I can’t reproduce that kind of nightmare in my studio, I can’t comment on that.  Like I said, for reasonable, typical humming issues, the XIT-600 will do just fine. But loud humming, bad cables or what have you, it could be anything causing that hum.  If the XIT-600 doesn't solve the problem, you might have to get something bigger and more expensive perhaps. This one worked for my needs. [I have received this product in exchange for my honest review].
