DAAS4 Pro speaker tester
DAAS (Digital Audio Analyrer System ADM Engineering) is a German company specializing in audio manufacturers as a product design, development, quality control, digital audio measurement analysis system based on PC platform and the development of a set of. Divided into DAAS3L, DAAS4Pro (96KHz/192KHz), DAAS4usb three series.
Function IntroductionTechnical ParametersConfiguration Checklist
Engineering Company specifically for audio manufacturers as a design, development, quality control, and development of a measurement and analysis system based on digital audio PC platform. Divided DAAS3L, DAAS4Pro (96KHz / 192KHz), DAAS4usb three series.

Use 40kHz, 24 bit digital / simulation and emulation / digital converter, a signal and perform tests
Frequency and impedance measurement frequency regulator Festival resolution
Frequency and impedance curve with automatic delay correction phase calculation
Acoustic measuring line in addition to the phase correction
In addition to group delay line phase group delay calculation
Transient response and the cumulative spectral attenuation (waterfall)
Young liberal tone frequency response curve correction
Distortion measurement frequency of any internal letter Diao
External signal distortion measure
Distortion and frequency, level assessment
Intermodulation distortion measurements: Tim and Dim
Thiele small parameter calculation
The maximum frequency resolution 0.1Hz
With speaker-aided design software Akabak, CALSOD and supporting the use of LEAP
RT60 and narrowband noise
Automatic test macro editing, Go / No Go judgment
Test drive turntable can be point to point test


It uses 16-bit or 24-bit D / A and A / D converter generates test signals and calculation, and calculated test signal, the test interface consists of graph, the title kind of information like composition, simple and intuitive graphical user testing capabilities menu prompts to make your work easier measurement.


1) DAAS4Pro: PCI4 bit 2-channel A / D, before and after D / A conversion utility card-level control box (with power amplifier MIC phantom power and preamp) Microphone (15V or 48V)
2) DAAS4usb: USB front interface level control box (with power amplifier MIC phantom power and preamp) Microphone (15V or 48V)

DAAS4 pro can buy QC Extension software frequency response, polarity, impedance, harmonic distortion, rub & buzz, average sensitivity of the online quality control functions, and all test results can directly generate Excel reports for quality analysis.
