28. EQ OUTPUT (8 pin circular plug; pin configuration: please refer to Table 9)Connects a proper microphone cord (Optional) for the transceivers9. GroundWhile using this unit, in case of high VSWR with antenna, leakage of coaxial cable, external power supplynoise, external noise, etc., connect a wire between the transceiver and ground terminal of this unit.Please try this when such noise is involved and enjoy communication without any noise.10. POWER INPUT TERMINALMost recent transceivers providing DC 5 - 9 volts for the microphone can power the EQ-2000 by properwiring of microphone cord. However, 4 pin old type transceiver or tube type transceiver does not providepower from the microphone connector. In such case, you can externally power DC 8 - 18V through the DCterminal of EQ-2000 with a battery or low ripple well regulated power supply or AC adaptor.Wiring method for various transceiversPlease refer to the following Table 1 to Table 8, and Figure 1.Method to change the wiring is as follows: 1. Loosen 4Ea of M3*8 nut from top cover; 2. Connect a CON1,CON3, J1, J2, J3, and PCB ground terminal to your microphone after referring to the following Tables.Table 1.
