½-inch microphone preamplifier, tapered, incl. cable, 7-pin LEMO connector

This ½" microphone preamplifier operates over a wide range of temperature, humidity and other environmental conditions.

USE SCENARIOS

• Sound measurements with Brüel & Kjær 1/2" (1", 1/4" and 1/8" with adaptor) and compatible microphones
• General-purpose preamplifier and high-impedance input probe for Brüel & Kjær measuring instruments

FEATURES

• The preamplifier, cable and its connectors all fulfil electromagnetic compatibility (EMC) requirements
• Compact LEMO connector at preamplifier. Connector: lemo 0B 7 pin & lemo 0B to lemo 1B
• Patented charge-injection calibration technique for on-site calibration of the whole measuring channel including the microphone
• Wide dynamic range
• Very low inherent noise, high input impedance
• Low output impedance and high output current allows use with long extension cables
• Wide working temperature range

The preamplifier has a very high input impedance presenting virtually no load to the microphone. The high output voltage together with an extremely low inherent noise level gives a wide dynamic range. The preamplifier’s low output impedance allows the use of long extension cables without problems. You can connect ½" microphones directly and 1", ¼" and 1/8" types using adaptors.

You can verify the condition of the microphone, preamplifier and cable on-site using its patented charge injection calibration technique.
