Specifications

Note:
• All specification values are based on using a typical bodypack with 5 V bias input or the RPM400MTQG preamplifier.
When using the RPM400LEMO amplifier, refer to the RPM400LEMO specifications.
• All specifications measured with a 48 Vdc phantom power supply. The microphone operates at lower voltages, but with
slightly decreased headroom and sensitivity.
