Page 67FT D X 1200 O PERA T ING M ANUALPArAMetric Microphone equAlizer (SSb/AM/FM Mode)The FT DX1200 includes a unique Three-Band Parametric Microphone Equalizer that provides precise, independent con-trol over the low, mid and treble ranges in your voice waveform. You may utilize one group of settings when the speechprocessor is off and an alternate group of settings when the speech processor is on. The speech processor feature is de-scribed in the next chapter.quick point:The Parametric Equalizer is a unique technique for adjusting the signal quality. The three audio ranges may be adjustedso precisely, it is possible to craft an audio response that provides a natural and pleasant sound that you may not haveever experienced before. Alternately, the effective “talk power” can be significantly enhanced.The aspects of configuration that you may adjust on the Parametric Equalizer are:Center Frequency: The center frequency of each of the three bands may be adjusted.Gain: The amount of enhancement (or suppression) within each band may be adjusted.Q: The bandwidth over which the equalization is applied may be adjusted.Setup of the Parametric Microphone Equalizer1. Connect the microphone to the MIC jack.2. Set the RF output power to minimum value viaMenu item “177 TX MAX POWER”, so you will notcause interference to other users while making ad-justments.A dvice : We recommend that you connect a dummy loadto one of the Antenna jacks, and monitor yoursignal on a separate receiver, to prevent interfer-ence to other users. You will have the best chance of hearing the ef-fects of adjustments if you wear headphones(connected to the monitor receiver) while listen-ing to your transmitted signal.3.

Press the [SELECT] button, then rotate the [VFO-B/CLAR] knob (or press the / button) to performadjustments to a particular Menu item.8. Close the PTT switch, and speak into the micro-phone while listening to the effect of the changesyou are making. Because the overall effect on thesound will change with each adjustment, you shouldmake several passes through each adjustment area, tobe sure that you are achieving the optimum settings.9. When you have completed all adjustments, press the[SELECT] button, then press the [MENU] button tosave the new settings and exit to normal operation.If you only press the [MENU] button momentarilyto exit, none of the changes you performed will bestored.A dvice :To roll off excessive bass response in a wide-range stu-dio microphone, try putting a 10 dB null at 100 Hz witha bandwidth of “1” or “2”, do about a 3 dB null centeredon 800 Hz with a bandwidth of “3,” and then put an 8dB peak centered on 2100 Hz with a bandwidth of “1.”These are starting recommendations; each microphoneand user’s voice will be different, often requiring differ-ent settings.enhancinG transmit siGnal Q ualitY[VFO-B/CLAR] Knob[MENU] Button [SELECT] Button[MONI] ButtonTo adjust the Parametric Microphone Equalizer withthe speech processor engaged, press the [///]button to select the “PROC”, then press the [SE-LECT] button to select “ON”.“ON”4.
