Graphic EQ operations Graphic EQ operations About the graphic EQ The LS9 lets you mount a GEQ in racks 1-8 and patch it to the insert-out/in of a channel. You can use the top panel faders and [ON] keys to operate the amount of boost/cut for each band. The following two types of GEQ are provided. ● 31 Band GEQ This is a monaural 31-band GEQ. Each band is 1/3 octave wide, the adjustable boost/cut range is ±15 dB, and the amount of boost/cut for each of the thirty-one bands can be adjusted. If a 31 Band GEQ is mounted in a rack, one channel of input and output can be used for that rack. INPUT Rack OUTPUT 31 Band GEQ Inserting a GEQ in a channel The LS9's GEQ units can be patched to the insert-in/out of any channel except the ST IN channels. Here's how to insert a GEQ into the selected channel for use. 1 As described in steps 1-3 of "Mounting a GEQ or effect in the virtual rack" (→ p. 158), mount a GEQ in a rack. The GEQ/EFFECT field shows the approximate settings and input/output levels of the GEQ. A rack in which a Flex15GEQ is mounted will show information for two GEQ units (A and B). ● Flex15GEQ This is a monaural 15-band GEQ. Each band is 1/3 octave wide, and the adjustable boost/cut range is ±15 dB. The Flex 15GEQ lets you adjust the boost/cut amount for any fifteen of the same bands as the thirty-one bands of the 31 Band GEQ. (Once you've used up fifteen bands of adjustment, you won't be able to adjust the boost/cut amount of another band until you reset a previously-adjusted band to the flat setting.) A rack for which the Flex15GEQ is selected will have two Flex15GEQ units (shown as "A" and "B" respectively) mounted in that rack, and will allow two channels of input and output. If you mount a Flex15GEQ in each rack, you'll be able to use up to sixteen GEQ units simultaneously.

This will let you link the two GEQ units later. 17 Graphic EQ and effects 2 Use the INPUT button to open the OUTPUT CH SELECT popup window where you can select the input-source for the rack, and choose the insert-out of the desired channel. The insert-out will be assigned to the input of the GEQ. (For details on the OUTPUT CH SELECT popup window → p. 159) HINT • If you select the Insert Out of a certain channel as the input source, the Insert In of that same channel will automatically be selected as the output destination for that rack. For details on Insert Out/In, refer to "Inserting an external device into a channel" (→ p. 101). LS9-16/32 Owner's Manual 161
