MI-3111

The MI-3111 is an exclusive preamplifier for 1/2-inch back electret-type microphone, which is applicable to CE marking*1. The MI-3111 also conforms to EMC so that it has high tolerance for noise. Featuring constant current operation, with a BNC input, thereby improving its ability in connection. Various types of instruments such as amplifier, instruments and data recorder with CCLD*2 can be connected directly.

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.)

MI-3310

The MI-3310 is a preamplifier for use with a 1/2-inch condenser microphone, accepts both of bias-type and back electret-type microphones. It can be directly connected to an analyzer such as DS-2000 series, CF-3600A / 3800, CF-5200Z series, CF-7200 and covers a wide frequency range of 10Hz to 100kHz. A cable, AG-3300 series, is necessary for connection. (sold separately)
