A verification system for testing production lines that includes rub & buzz noise. Designed for a wide range of use from micro-speakers to large speakers.
With the same operability and familiarity as the conventional ETANI instruments, it adapts to your new environment without stress, and enables you to handle highly specialized tests with extended features.
Allows you to perform a wide range of measurements and rub & buzz tests repeatedly at high speed and accuracy. Distinguishes good/defective samples on time.
The standard model has a built-in 50W amplifier, and also supports the control of external amplifiers via the LINE OUT connection.
S-355 MEASUREMENT CAPABILITY
The S-355 Loudspeaker Test System is an instrument for the production lines that can also measure rub & buzz noise. The system automatically tests all characteristics that are required of speakers in a short time, and performs pass/fail judgments.
Test Items: Windows 10 compatible
Sound pressure level frequency response
Total harmonic distortion / 2nd & 3rd harmonic distortions
Impedance characteristics
Phase characteristics
Rub & buzz characteristics
Sensitivity (S0)
Impedance (Z0)
Lowest resonance frequency (f0)
Polarity(Po)
Isolation test (option)
If the test voltage is identical, multiple items are tested at once. If different, changes for each voltage, and sweeps to measure and process.
OTHER FUNCTIONS
Statistical processing of all test data online in real time. Outputs average, standard deviation, CP, CPK, histogram and Pareto chart, etc. Allows you to create quality control database (option).
The measuring unit has an integrated structure with a built-in 50W power amplifier. It can also be controlled by connecting to an optional external power amplifier (100W output / 0.5Ω ~ 8Ω), via the OUTPUT connection. The entire system comprises a PC, a microphone, an anechoic box, and jigs.
