MODEL 9350C PRECISION ACOUSTIC CALIBRATION WORKSTATION The Precision Acoustic Calibration Workstation Model 9350C is an automated, accurate, turnkey, PC-based system that features cost-effective calibration of 1⁄8 in, 1⁄4 in, 1⁄2 in and 1 in microphone cartridges (open-circuit sensitivity), microphone cartridges with preamplifiers (closed-circuit sensitivity), as well as microphone Frequency Response Function. In addition, the system provides for conformance testing of microphone preamplifiers and acoustic calibrators: this includes pistonphones as well as speakerphone-based calibrators. Under complete software control, the 9350C operates in four modes: • Microphone Cartridge Calibration • Microphone & Preamplifier Calibration • Preamplifier Conformance Test A calibration certificate may be generated and results saved in the software database. • Full Windows 7/Vista/XP • Complies with IEC 61094-6 and IEC 60942 • Streamlined, easy and intuitive operation throughout • Comma Separated Variable (CSV) export of calibration data for integration into an existing database • Easy and fast retrieval of calibration certificates from a model/serial or asset number filtered list • Automatic free-field and random incidence correction curves applied for those types of microphones Customer : TMS Rental 5 dB 0 • Sound Source Calibration (i.e. pistonphone, speakerphone, etc.) F E AT U R E S : ~Certificate of Calibration~ Description: Free-Field Microphone Manufacturer: Larson Davis Model Number: 2620-PM 1007 Serial Number: -5 -10 -15 10 100 Test Results: Sensitivity: Cal.

The lower curve is the pressure response recorded by electrostatic actuator. Sensitivity : The stated sensitivity is the open-circuit sensitivity. When used with a typical preamplifier the sensitivity will be 0.2 dB lower. Polarization Voltage : 200 V Traceability : The calibration is traceable through 822/278767-10. Notes : Calibration results relate only to the items calibrated. This certificate may not be reproduced, except in full, without written permission. This calibration is performed in compliance with ISO 9001, ISO 17025 and ANSI Z540. Measurement uncertainty at 95% confidence level: 0.30 dB. Calibrated per procedure PRD-P204.

System verification procedures function to assure a stable, consistent operating environment and reduce systematic and random errors to a minimum. With easy, user-friendly operation and proven stepped sine excitation method, the 9350C provides fast, consistent, reliable calibrations and excels in efficient, high-volume transducer calibrations, just like the manufacturers do it. The system also allows for easy integration of user-defined logos for customized calibration certificates.
