LouderSpeaker testing

LouderSpeaker testing 

System introduction

TotalSound is an easy-operating, flexible, powerful electroacoustic testing system, purpose-designed based on PC operating system by SoundFree Limited. TotalSound gives out the real-time results exactly to show you if the results are good or bad, generating reports as your requirement.

It is more accurate and high speed to test louder speaker, it is suitable for production line, we have new power amplifier which integrated with bias resistor, to substitute the impedance box, more easy to setup and ensure the precision, the new format stimulus, conforming to ISO standard, make sure you set the testing time less than 1s, it is perfect for customer.

The TotalSound testing system can use footswitch to start, through RS232, the testing parameters include two items: acoustical and electrical, the two items tested simultaneously, this can improve the testing speed and the efficiency

Testing Field

1)     Labs

2)     Manufacturing lines.

Test parameters as below:

n  Frequency Response

n  THD(total harmonic distortion), THD+ N

n  Rub&Buzz(%), Rub&Buzz Normalized(%)

n  Impedance

n  Phase and Polarity

n  Fo and average sensitivity

Ordering information

1)     TotalSound system

2)     Soundcard

3)     PA100-power amplifier

4)     PS200-microphone power supply

5)     M300-2FL-standard microphone
