Supply LMS4.5 Speaker Tester

LMS, LX500, horn speaker tester LMS measurement system based on the speaker test system consists of a PC ISA expansion cards, RS232 cable access products, Windows applications, and a calibrated microphone M31 (standard) components. QC tests are available for the speaker, speaker design and development, as well as a variety of common electro-acoustic measurement. Its rich graphical user interface makes the system easy and functional operation greatly enhanced. Is a very high cost of electro-acoustic analysis system that provides high-quality data suitable for practical application of electro-acoustic engineering, and powerful computer-based, with particular emphasis on meeting the unique requirements of development and QC testing speakers, a professional sound system, ideal tool for home audio systems, car audio, sound engineering acceptance. Support any brand printers. Libraries can save 99 curve curve compared with the average. Curve can be transferred directly to the LEAP-5 for analysis. Multi-curve copy / paste transfer. Accurate speaker argument deduction. Speaker simulation parameters. Powerful export function chart. Manual frequency scanning. Scanning accuracy up to 800 points. Test the macro editor. Edit microphone parameter file created. Curve color, background, thickness of any modification, convenient overlap, print, compare. Edit curves, create, modify. Powerful post-processing and directional polar diagram display. Hardware: LMS from low-distortion sine wave oscillator, bistable adjustable tracking filter, microphone preamplifiers, gated peak / average level detection circuit. Including a group of line-level output, balanced line inputs and the active microphone input. Optionally four methods for measuring, external microphone preamplifier can be used for level calibration, the test frequency range from 10Hz to 100KHz, and 16-bit digital audio dynamic range of 90dB. The system has a high resolution, 10Hz each allow up to 200 logical spatial frequency data points, each pixel on the screen corresponds to one data point. Dual trace filter can be flat, low pass, high pass, band pass and band stop several response measurement. Measurement accuracy and flexibility comparable to other costly system several times, for novice and experienced veteran, are easier to set up and operate. System Software: eight kinds of measurement modes: voltage, SPL, impedance, RT60, inductors, capacitors, voltage, pole figures. All hardware functionality of LMS can be controlled and modified by the analyzer parameters dialog, but also save the file in the future as a quick call to the control panel setting parameters on disk for. Any frequency within 10Hz to 100KHz sweep point range, precision scanning points selectable from 2-800 points. All figures are in a WYSIWYG fashion drawing board design. Screen display and printouts same. Users can perform a variety of design elements graphic full control, including the type of font, color and line. The system also provides input project name, personnel, and custom graphic file name of the company, which also comes with a graphical layout and precautions comment zone area. Using any standard Windows printer driver, can support high-resolution full color printing
