    Bruel & Kjaer 2669 Pre-Amplifier:
    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 and its connectors all fulfill electromagnetic compatibility (EMC) requirements
    Compact LEMO connector at preamplifier. Connector: lemo 0B 7 pin
    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 2669 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 2669'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.
