17 - TUTORIAL - Using the notch filters, and the HPF and LPF II. Editing the filters graphically 1 Press the [DISPLAY] key until you see a screen similar to the one here. (It comes immediately after the SWEEP screen.) The actual settings on your screen will probably be different to the ones shown here. 2 To select a filter for editing (if it's not already selected), press one of the notch or filter selectors. The indication in the top left corner below the "Lch" or "Rch" indication shows the filter that is currently selected for editing. It will either show NOT1, 2, 3 or 4, HPF or LPF. NOTE If you wish to see and hear the effects of the filter while you are editing it, make sure the indicator above the filter selector is on. If not, press the selector. 3 Use the F rotary encoder to move the filter up or down the frequency band. 4 For the notch filters, use the Q rotary encoder to alter the Q of the notch. As you adjust the filter parameters, the F (and Q if you're not editing the HPF or LPF) will be shown numerically at the top of the screen. If the filter is turned on (the appropriate indicator is lit), the screen will show the frequency response of the filter settings. Notice the extra width of the notch on the left, with Q of 0.5. III. Editing the filters numerically 1 Press the [DISPLAY] key until you see a screen similar to the one below. (It is the second of the two filter screens.) The actual settings on your screen will probably be different to the ones shown here. 2 To select a filter for editing (if it's not already selected), press one of the notch or filter selectors. The corresponding "NOT", "HPF" or "LPF" indication on the left side of the screen will become highlighted, and a cursor will appear beneath the parameters for the currently selected filter (either the F or Q parameter will be underlined). For any filters that are off, a dash ("-") will appear in the second column of the display. For filters that are on, this is replaced by a small symbol representing the filter. NOTE If you wish to see and hear the effects of the filter while you are editing it, make sure the indicator above the filter selector is on. If not, press the appropriate selector to turn it on. 3 Use the F rotary encoder to alter the frequency of the filter. 4 For the notch filters, use the Q rotary encoder to alter the Q of the notch. The figure shown is adjustable from 0.5 to 10.0 (10.0 is the narrowest). Of course, the HPF and LPF shelving filters do not take Q values. YDG2030
