Frequently asked questions
Which microphone works better for capturing a drum kit or acoustic piano?
The PZM30D is purpose-built for drums and piano when placed on a surface; its switchable brightness setting is optimized for those instruments. The CM311 is designed for voice isolation and is not ideal for acoustic instrument recording.
Which one isolates the speaker's voice from audience noise?
The CM311's cardioid pattern and shock mount are engineered specifically to reject ambient noise and mechanical interference, making it ideal for lectures, theater, and broadcast where voice isolation matters. The PZM30D picks up sound from all directions and is not designed for rejection.
Can I use either one for worship/church applications?
Both are listed for worship use but serve different roles. The PZM30D works well for capturing choir, organ, or ambient room sound from a fixed surface. The CM311 suits a pastor, worship leader, or praise singer who moves around the stage and needs voice isolation.
What is the key technical difference in polar pattern and why does it matter?
The PZM30D uses a hemispherical pattern to pick up sound equally from all directions around it. The CM311 uses a cardioid pattern to reject sound from the sides and rear, focusing capture on what is directly in front of it. Hemispherical suits ambient/room pickup; cardioid suits isolated voice capture.
