Using Graphic EQ  Linking the right and left stereo signals You can edit the right and left channels together by linking the right and left stereo signals. In the initial state, the link is set to "ON." Disabling the link allows you to set parameters separately for the right and left channels. 1. Press the GEQ button below the display repeatedly if necessary until the GEQ MODE page appears. 2. Rotate Knob 1 to select "L/R Link", and then rotate Knob 2 to set to "ON." The parameter value flashes. 3. Press Knob 2 while the parameter value is flashing. The screen prompts you to reset the gain. Finding and removing feedback Using the offset gain lets you check the feedback point in advance, and feedback can be reduced by correcting the gain with GEQ. 1. Press the GEQ button below the display repeatedly if necessary until the SWEEP page appears. If the "L/R Link" is set to "ON," the "SWEEP L/R" page appears. If the "L/R Link" is set to "OFF," the "SWEEP Lch" page or "SWEEP Rch" page appears. Frequency 14BandGEQ Offset * Actual gain -4.0dB= -10dB+6.0dB 4. Press Knob 2 again to select "OK," or Knob 1 to cancel. The gain will be reset, and the link setting is executed. The indication on the upper right side of the GEQ EDIT and the GEQ SWEEP screens changes to "L/R." Clearing the link setting 1. In step 2 above, change the parameter value from "ON" to "OFF." 2. While the parameter value is flashing, press Knob 2. The screen prompts you to confirm "Break Link?" 3. Press Knob 2 again to select "OK," or Knob 1 to cancel. The link is disabled. Frequency Flex9GEQ Offset * Actual gain +4.5dB= -1.5dB+6.0dB * Actual gain = parameter (setting) value + offset 2. Rotate Knob 2 to specify the rough offset value. Raise the gain temporarily by using the offset setting to create a situation with no feedback margin, and find the feedback point. 3. Rotate Knob 1 slowly to find the feedback point. You will start to hear feedback when the frequency reaches the feedback point. 4. When the feedback point is found, rotate Knob 2 to lower the offset to a minus value in order to reduce feedback. 5. When the final adjustment has been made, press Knob 2. Offset will be added only to the setting value of the adjusted frequency. 6. Repeat steps 2 -5 as necessary to adjust the GEQ settings.
