Crown PZM-30D

The PZM (Pressure Zone Microphone) is ideal for recording critical music or voices. The PZM-30D has integral XLR output connector, the PZM-6D has hard wire output. Both have flat or rising response switchable. Phantom power only.

Features

• Pressure Zone Microphone design prevents coloration from surface sound reflections
• Choice of flat response or rising highfrequency response
• PZM-30D uses a rugged detachable cable
• PZM-6D is smaller, lighter, and has a permanently attached cable
• Hemispherical pickup pattern
