AWA14604E Preamplifier Specialized Multi-pin B&K or LEMO Connectors

The AWA14604E preamplifier is powered by a constant current source (ICP) and integrates signal and power lines into a single cable. It features a BNC output connector, allowing for convenient connection to the standard BNC inputs of general-purpose measuring instruments using a simple single-core shielded BNC cable—eliminating the need for specialized multi-pin B&K or LEMO connectors—which makes it highly popular among users. Manufactured by our company, the AWA14604E preamplifier is characterized by high input impedance, low output impedance, and low noise. It supports cable runs of up to 100 meters between the preamplifier and the measuring instrument and is designed for use with Φ12.7 mm (1/2-inch) prepolarized measurement microphones in applications such as multi-channel noise analyzers.
