Soyo wireless power amplifier module solution>>> Description:1). Frequency: 2.400--2.483GHz2). Channels: 203). 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@16bit*2, Frequency response: 20--20KHz; HDCD Sound effect; Two digital number display 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 circuit9). Small size and highly integrated.10). We have the lowest latency (<0.5ms), and good quality of surrounding11). 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 display17). Flexible design supporting custom functions18). Indeed convenient to use and easy to handle.>>> Applications: 1). Wireless speakers2). Wireless headphones3). Surround speakers4). Channel-surround sound boxes being wireless.5). Wireless microphones 6). Wireless Guide Speaker7). CD/DVD players or other musical facilities.8). wireless eavesdropping9). Wireless Simultaneous interpretation System10). Wireless megaphone11). Wireless Loud-speaker12). Supporting facility of wireless audio transmission in sound system13). Supporting facility of wireless audio transmission in monitoring projectPCB boards:Certificates:NO.DescriptionTransmitter moduleReceiver module1Work voltage3.6- 6V DC2.5 - 3.6V DC2Work electric currentMax 120mAMax 35mA3Work temperature-15 – 65 degree-15 - 65 degree4Frequency response2400 - 2524 MHz2400 - 2524 MHz5ModulationGFSK6Baud rate2Mbps2Mbps7Channel space4MHz4MHz8Stabilization of frequency+/-156KHz+/-156KHz9Work frequency range2400 - 2483 MHz2400 - 2483 MHz10Work channel20 CH20 CH11Channel space of module4MHz4MHz12Output power0-20 dBm13Receiver sensitivity90dBm14Input powerMax 1.0Vrms15Input impedance10k Ohm16Input modeTwo input modes: 1.
