Soyo 2.4G HI-FI digital wireless speaker modules solution
model: SOYO-WM24G02

>>> Features:

1. digital transmission
2. lowest latency time
3. strong anti-inference
4. broadcasting mode (point to multi-point transmission)
5. digital wireless speaker module solution

>>> Description:

1). Frequency: 2.400--2.483GHz

2). Channels: 20

3). Two types of input supporting microphones and stereo and UPS On-line real-time switch as well.

4). Digital transmission.

5). Additional 20dB selection can be available with microphone input

(for the high-sensitivity microphone, eavesdropping applications)

6). Sampling ratios: We have the highest sampling ratios in the field: 64k at 16bit*2, Frequency response: 20--20KHz, HDCD Sound effect, Two digital number ldisplay on the Digital Volume and the channel change

7). Digital volume adjustment to 127 grades.

8). The main switch can get rid of the switching noise with noise elimination circuit

9). Small size and highly integrated.

10). We have the lowest latency (0.5ms), and good quality of surrounding

11). Low power consumption for a wide range of input voltage.

12). Audio muting function when receiving weak signals or no signals.

13). Function of auto channel scanning.

14). Selection of TX power: 0--20dBm (Decided when ordering) RF range can be up to 180 meters with the greatest TX power in an open field.

15). For the application of head-phones, the receiver particularly provides no signal standby dormancy function. And the standby current is less than 0.5mA.

16). Interface of Channel display

17). Flexible design supporting custom functions

18). Indeed convenient to use and easy to handle.

>>> Applications:

1). Wireless speakers

2). Wireless headphones

3). Surround speakers

4). Channel-surround sound boxes being wireless.
5). Wireless microphones

6). Wireless Guide Speaker

7). CD/DVD players or other musical facilities.

8). wireless eavesdropping

9). Wireless Simultaneous interpretation System

10). Wireless megaphone

11). Wireless Loud-speaker

12). Supporting facility of wireless audio transmission in sound system.

13). Supporting facility of wireless audio transmission in monitoring project.
