The MI-3110 is a low-cost preamplifier for use with a 1/2-inch condenser microphone, featuring constant current operation, with a BNC input, thereby improving its ability in connection.
When disturbing the sound field would be a problem, an optional extension rod can be connected to the MI-3110 to prevent disturbance. (The maximum measurable sound pressure level will be 135dB when combined with MI-1233/1234/1431/1432.)
