Graphic EQ and effects
This chapter explains how to use the built-in graphic EQ and effects, and how
to perform remote control operations via the dedicated protocol to control an
external head amp (Yamaha AD8HR) from the LS9.
The LS9 lets you insert the built-in graphic EQ (subsequently abbreviated as “GEQ”) and effects
into the desired signal route to process the signals.
You can use two types of GEQ; 31 Band GEQ which lets you freely adjust thirty-one bands (fre-
quency regions), and Flex15GEQ which lets you adjust any fifteen of thirty-one bands. You can
also use 48 different effect types.
In order to use a GEQ or effect, you must mount the GEQ or effect in one of the eight virtual racks provided in the screen,
and patch the input and output of that rack to the desired signal route. In other words, the operation is just as though you had
installed a signal processor or effect device in an actual rack, and used patch cords to connect it. Only GEQ can be mounted
in racks 1–4, and either GEQ or effects can be mounted in racks 5–8. [Figure 1]
Up to two channels of input and output can be used for each rack. (However if the “31 Band GEQ” is mounted in a rack,
there will be only one channel each for input and output.) [Figure 2] shows the signal flow for the virtual racks.

Only for GEQGEQ or effects
• In addition to the virtual rack for GEQ and effects, there is also a rack for mounting external head amps
(Yamaha AD8HR). For details, refer to “Using an external head amp” (
→
p. 175).
