I’ve recently started jamming with some guys around the studio once in a while just for fun, but I ran into a slight problem: I need to keep my drum mics connected to my mic preamps so they’re always ready for recording drum tracks. However, I also needed to connect my drum mics to my live mixer (a Behringer X-Air XR18) so I can use my in ear monitors and add drums to the mix when jamming. So to put it simply, I needed a way to split the signals from my drum mics and send them to a couple of different sets of inputs. (more…)

One of my most popular articles has been The Mono Summing Cable that No One Makes. I’ve been contacted by more readers regarding that article than probably any other that I’ve written. That article details why it’s a bad idea to use a regular Y-cable or TRS-to-TS cable to sum two (usually stereo left & right) line-level signals to mono by simply shorting the outputs together. It’s ok to use such a cable for SPLITTING a signal, but not for COMBINING or SUMMING two signals. That being said, it can work ok on some devices, but on others it can cause distortion, weird phasing artifacts, and possibly even damage the outputs of your gear. However, combining the outputs of two dynamic microphones is a different story, and in some applications it’s ok to do so with a regular XLR Y-cable, as we will soon see. (more…)
