2670-WB-1419 -
¼-inch microphone preamplifier, integral 2m cable with 7-pin LEMO plug
The preamplifier is very compact and operates over a wide range of temperature, humidity and other environmental conditions. Optimised for airbag measurements.
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. The preamplifier is supplied in an elegant yet strong plastic box made from recyclable materials.
Features
- Full electromagnetic compatibility (EMC)
- LEMO connector for instrument input socket
- 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 allow use with long extension cables
- Wide working temperature range
- Excellent phase linearity
The high distortion limit together with an extremely low inherent noise level gives a wide dynamic range. ¼" Microphone Preamplifier Type 2670 is a Falcon Range product for precision acoustic measurements with Brüel & Kjær’s wide range of condenser microphones. 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.
