8. tly selected channel is emphasised Tone control adjustments apply equally to both channels The room calibration function of the P 3000 HV PA 3000 HV consists of three equalizers per chan nel The program calculates the effect of the equalizer setting beforehand so that you can directly see any change to the settings Before adjusting the equalizer See next section you should therefore either carry out the loudspeaker calibration process or load an existing frequency response curve The individual equalizers can be adjusted once the curve has been loaded or recorded the first stage is to determine the points where there are significant peaks or troughs The exact frequency can be found by moving the cursor line to the appropriate point using the mouse the frequency is shown above the line If you wish to alter the equalizer settings you must first remove the tick at Room calibration off The values for frequency Hz and level dB can be in creased or reduced by means of the arrow buttons in the appropriate window Adjust the three equalizers in such a way that the frequency response is as smooth as possible When you have optimised the frequency response you can transfer the equalizer settings to the P 3000 HV PA 3000 HV If the device is connected using a network cable the values can be trans ferred by clicking on the Set EQ button If there is no network connection the values must be entered manually
