To provide high purity signals for speakers attend an audition. Low distortion rate of scanning is Hyun-THD ≤ 0.15%, 20 Hz-20KHz, the most suitable for testing speakers, electro-acoustic components of the unusual sound.
Table shows that the word voltage and frequency table: All figures show that voltages and frequencies to meet the requirements of precision, than the traditional meter more durable Pointer
Sweeping the few: either manually or automatically on a few Sweep, sweep since / So just need to follow any frequency range set
Easy to learn and use: key function is simple and clear, non-professionals will also be used, with three short-circuit protection circuit, will allow the output short-circuit a long time, it will not damage equipment
Voltages are coarse and fine-tuning set-button: resolution of 0.001 V voltage form, supplemented by rough-and fine-tuning of the volume adjustment buttons can be easily transferred to the required voltage. The receiver and headphones for precision low voltage value, easy to set
Excellent reliability: a low failure rate, high stability, defying the continuous use of all-weather
Fo values can be manually test, the frequency can be fine-tuning
Figures show that the frequency table, complemented by fine-tuning the frequency button, it can be accurately measured, such as Speaker of the value of the minimum resonant frequency Fo
There are 20 W, 40W, 60W, 100W options
