Bruel & Kjær 2693--0S4 Nexus Conditioning Amplifier

The Bruel & Kjær 2693-A-0S4 Nexus Conditioning Amplifier is a four-channel NEXUS conditioning amplifier designed for use within Bruel & Kjær's NEXUS measurement system, providing four independent channels of conditioning with built-in A, B, C and D filters on each channel. It is listed in official product data as a 4-channel CCLD conditioning amplifier within the NEXUS family (Types 2690, 2691, 2692 and 2693) and targets conditioning sensor signals—most commonly microphones—in acoustic and vibration testing, delivering preamplification and selectable weighting/filters before data acquisition. The NEXUS range is modular, and a conditioning amplifier can be updated to another configuration if required to suit changing measurement needs. Setup and control are performed with Bruel & Kjær's NEXUS software (Type 7749), compatible with the 2693 family for configuration of channels, filters, and data paths. While designed for microphone conditioning, the 2693-A-0S4's four channels can accommodate a range of transducers used in acoustic and vibration measurements.
