Side by Side: On-air Condenser Mics


        Radio on FacebookJoin us on Facebook

Dynamic mics are everywhere. The EV RE-20 and its cousin the N/D-27 are probably the most ubiquitous dynamic studio mics in use. The Shure SM7 (and still sometimes the SM5) are also common. Heil has made inroads as well. Even Neumann has the BCM 705. But there is another option to the dynamic mic. Perhaps it's time to consider a condenser mic in the studio.

There are misconceptions about condenser vs. dynamic mics for on-air use. Some claim condensers aren't rugged enough for jock use. That's not really true any more. The cost of many condensers can be higher than a dynamic, but not by much. Condensers require phantom power, but most preamps and consoles can provide that with no effort.

There are potential benefits for condensers. Condensers usually have a lower self-noise floor and higher sensitivity than dynamics. A condenser's lighter diaphragm (compared to a dynamic) can respond quicker to transient sounds. Condensers typically have a flatter frequency response as well. We selected a few common condenser choices for radio studios.
