Feafures：

1.True diversity receiver which of dual channel independent inquiry system for Minimize off frequency

2.The frequency can be synchronized between receiver and transmitter via infrared. Noise technique, PLL synthesized technique and digital pilot technique.

3.LED display indicates the system volume, battery, channel of A/B switch, work frequency, receiving distance gear and the system locked key etc.

4.Display showed a red voltage alarm when the transmitter battery voltage low. Dual channel AFS frequency automatic search function in dependently.

5.Automatically search for the cleanest channel.

6.There are 3 * 10 LEDs in the A/B channel which indicate RF signal strength of A/B channel, level signal strength and working state.

7.System adopts electronic volume control so that higher precision and put an end to the resistance of the potentiometer noise.

8.Adopt audio reference companding technique .Excellent dynamic response and excellent sound quality.

9.The SR - 66A true diversity wireless system is designed for touring and fixed installation application designing, and provide many different sound property of cartridge replaced. Its reliability is higher, sound quality and transmission more stable.

10.Receiving distance HI/MD/LOW can be adjusted.
