2669  ½-inch Microphone Preamplifier

Price: 269 euro

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.1/2" Microphone Preamplifier Type 2669 is a Falcon™ Range product for making precision acoustic measurements with Brüel & Kjær's wide range of condenser microphones. You can connect 1/2" microphones directly and 1", 1/4" and 1/8" types using adaptors.

The preamplifier, cable and its connectors all fulfil EMC requirements.

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

The preamplifier's low output impedance allows the use of long extension cables without problems.
