Summing Two Mic Signals


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…)

Audio Technica ATM230–a New Standard in Tom Mics?


If you’re in need of some tom mics, check out the Audio Technica ATM230. These relatively new mics are getting rave reviews, and receive favorable comparisons to many classic tom mics, including the Sennheiser MD421 and e604, Shure SM57, and Audio Technica’s own ATM25 and ATM23HE. One forum post commented that based on the specs, the new ATM230 is “…basically an ATM25 in an ATM23HE housing”. The ATM230 normally sells individually for $139, or can be purchased new in a 3-pack for $349. Zzounds even has a steal of a deal on a warehouse resealed 3-pack for only $220! Each mic includes a zippered storage pouch and a drum rim clamp.

Tom Mic Shootout Revisited

A few years ago, I blogged about a tom mic shootout that I conducted between two very popular mics for toms: the Sennheiser e604 and the CAD M179. At that time, I had been using the e604’s for recording my tom tracks and really wasn’t too thrilled with them. Meanwhile, I had been reading many positive reviews about what a great tom mic the CAD M179 made, so I ordered a pair to try them out. (more…)
