Type 2691-A-0S2 (Microphone)

Overview

Type 2691-a is described as a single probe intensity conditioner and the model code [-2691-A-0S2-] is listed as NEXUS 2-ch Intensity Conditoner. The NEXUS concept is based on a single mainframe with configurable input/output channels and different filter options, and it can accommodate acoustic and vibration inputs in the same mainframe with one, two, three, or four independent input channels. Microprocessors are used for control, display, and interfacing while the signal path is maintained analog to obtain optimum signal/noise ratio and the lowest possible distortion, and the system supports transducers with TEDS according to IEEE 1451.4; it can be reconfigured and updated with auxiliary modules including A-, B-, C- and D-weighting filters or integration. Number of inputs: 2. Input: 200V condensor microphones. Output: Voltage (+/- 10V). Interface: RS-232. Degree of protection: IP43. Housing: Standalone. Real-time capabilities: None. Accuracy class: ---. The product is specifically suited for automotive use and was developed in association with major car manufacturers for high-quality field and laboratory measurement systems. It is used with charge accelerometers, hydrophones, force transducers, condenser microphones, CCLD accelerometers, CCLD preamplifiers, voltage input, and sound intensity probes, and it is used for field recording of vibration and acoustic signals.
