In March, Kevin shared his techniques for improving sound quality by using sound absorbers. In this article, I cover two of my favorite microphones for voiceover recording: the Heil PR-40 and the Shure MV51. Each of these microphones delivers high quality sound for eLearning and podcasting applications. There are, however, important differences you should understand to determine which is right for you.
Let's start with the Heil PR-40, a dynamic microphone (meaning that it doesn't need power from a battery, USB connection, or mixer (sometimes referred to as "phantom" power). Dynamic microphones have a downside; they require a good quality microphone preamp to generate adequate recording levels. Without an amplifier, dynamic microphones produce recordings with low audio levels. This means that you may need to boost levels in post-production.
