SOYO ANNOUNCE OVERALL 2.4G HI-FI DIGITAL WIRELESS MICROPHONE SOLUTION

SOYO Technology Development Co. Ltd. has officially issued its 2.4G wireless microphone overall plan
    SOYO Technology Development Co. Ltd. officially issued its 2.4G wireless microphone overall plan based on its  2.4G digital wireless audio transmission module (Model: SOYO-WM24G02)in its headquarters in Shenzhen on December 12, 2008 , relevant samples of which were shown and tried  at the scene. The guests were all very satisfied with the audio-visual effect.

 The above mentioned 2.4G wireless microphone overall plan has the following characteristics:

1st, supporting infrared remote control function, which consequently realizes the true wireless control function: It may conduct the switch of the infrared remote transmitter, the digital volume fluctuation, the channel fluctuation and so on.

2nd, supporting nickel hydrogen rechargeable battery and the lithium rechargeable battery, and able to provide the built-in charge module, which works continuously for over 30 hours once it is recharged fully.

3rd, low voltage protection function: Supporting low voltage protection. When the battery voltage is lower than the normal threshold voltage, it enters the protection condition, and initiatively prompts the user to replace battery.

4th, to achieve high-fidelity sound quality, the overall plan provides as high as the 64K sampling frequency, meeting HDCD sound quality standard, which is presently domestic highest target in the field of wireless audio frequency transmission

5th, currently the products developed with the help of our overall plan by our former partners are practically seen on the domestic market and used in a number of large karaoke ok houses, filling in the gap of zero wireless microphone karaoke ok application. It turns out to be the best wireless microphone application.

We sincerely welcome customers both from home and abroad to develop the wireless microphone and the wireless microphone broad market with us.

Note 1: The sampling rate is the parameters which have been actually achieved by SOYO Technology Development Co. Ltd. rather than those which are mentioned in some publicity, such as: 96k at highest(but not actually achieved)but in reality, only 32 k/44.1k/48k sampling rate of products are actually available to customers. This note is just to remind you of that.

Note 2: About sampling rate

Sampling rate refers to the sampling frequency of the sound (analog) being transformed into digital signals. That is the number of the sampling points during a certain period of time. Each point has eight bits or more.

The sampling rate is similar to the number of dynamic images. For instance, movie's sampling rate is 24 HZ; the PAL pattern sampling rate is 25 HZ; the NTSC pattern sampling rate is 30 HZ. When we replay some sampled static pictures at their sampling rate, what we see is continuously moving pictures. Similarly, when we reply CD at the speed of 44.1KHZ, the same as the sampling rate of its being recorded, we can hear a continuous sound. And when HDCD is broadcasted at the speed of 64KHZ, the same as the sampling rate of its being recorded; it can become a sound of high quality and high fidelity. Obviously, the higher the sampling rate is, the more coherent the sound and pictures become. Certainly, resolution sampling rate of man's sense of hearing and the organ of sight is limited, and the sound sampled at 64KHZ is the limit for most people; the vast majority can hardly perceive the difference.

And the number in sound, similar to the number in the color of a picture, indicates each sampling data. The greater the data is, certainly, the more accurate the playback sound is. The sound of a boiling kettle won’t be confused as the train whistle. The same is true in the case of screen images, which may be clearer and more accurate, and blood can not be taken for tomato sauce at all. However, due to the restrictions of man’s organ function, 16 sounds and 24 pictures are basically the greatest to ordinary people. And greater data can only be distinguished by the instrument. For instance, the telephone is 7 sounds sampled at 3KHZ; CD 16 sounds sampled at 44.1KHZ; HDCD 16 sounds at 64KHZ. Therefore CD is clearer than the telephone, and HDCD is better in sound quality compared with CD. In principle, the higher the sampling rate is, the better the sound quality is. The different sampling rate and the bit rate will affect the fidelity of the digital audio equipment.
