Digital electro-acoustic power service life testing platform

Digital electro-acoustic power service life testing platform

DSP Digital electro-acoustic power testing platform adopts high-speed digital signal processing technology to integrate all electro-acoustic signaling sources. Its reliability is far better than the analogue components/TTL electric circuit elements and instruments widely used at home.

DSP Digital electro-acoustic power testing platform already includes following national standards and IEC international standard of audio-signaling sources.

  1. IEC 268-5: international standard
  2. GB 9396-96:National standard of China
  3. EIA 462B:— American industrial standard
  4. AES 2:American acoustic standard
  5. IEEE 219:European electro-acoustic standard(equal to IEC-268-5)
  6. DIN45573: National standard of Germany (equal to IEC-268-5)
  7. JIS C5532:Japanese standard (equal to IEC-268-5)
  8. White: white noise
  9. Pink: pink noise
  10. sweep: sine sweeping frequency signal

DSP Digital electro-acoustic power testing platform consists of a frequency band of 20-20KHz, a continuously adjustable digital filter of 24dB/oct. They can work together with above signaling sources to achieve demanded frequency width signal. DSP Digital electro-acoustic power testing platform adopts DSP technology, can set total working time of 0-990 hours casually, will provide multiple work modes (continuously, 1m/2m,1s/60s, 3h/3h) conveniently. With DSP technology, DSP Digital electro-acoustic power testing platform can monitor and record the working state for 1-40 paths real time, having sound and light alarm and printing functions. DSP Digital electro-acoustic power testing platform can select different types of power output combination according to different enterprises' requirements. It has outputs of single side 5 paths, double sides 10 paths and four sides 20 paths. Also, it can choose independent power releasing and outputting, at most can provide with two sets power releasing cabinets, 20 units power releasing, 40 paths independent output. DSP Digital electro-acoustic power testing platform is suitable for:

  1. Minitype loudspeakers (mobile phone, earphone, microphone, etc.)
  2. Television, multi-media sound box, radio, loudspeaker
  3. Automobile applied loudspeaker

Professional application in:

grand stage, plaza, big-powered PA sound box loudspeaker.

DSP Digital electro-acoustic power testing platform-D series

DSP Digital electro-acoustic power testing platform

DSP Digital electro-acoustic power testing platform-D series indicates that only one load is carried for each path of power release independently; there will also be independent voltage adjustor outputting mode. Inside is built the mainstream standard all-digit signaling sources currently for both domestically and at home. It is testing platform suitable for carrying out testing of service life span on bigger-powered (more than 25w) loudspeaker. Different quantities of power-release cabinet will be organized at random for customer's different requirement, including 4 (single-type) cabinets, 20 (double-type)cabinets, with 40 (three-type)cabinets at most, Max. (500W × 40)electro-acoustic power service life testing.
