Use Scenarios

Sound measurements with 1/4- and 1/8-inch Brüel & Kjær and other compatible microphones
Sound intensity probes

The high distortion limit together with an extremely low inherent noise level gives a wide dynamic range. You can connect ¼" microphones directly and 1/8-inch types using an adaptor. 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 (CIC) technique.

The low output impedance and high output current capability mean that you can use long cables between the preamplifier and your measuring instrument without loss of signal quality.
