User Manual

The output level from the KP90 can be raised by turning the level adjuster q clockwise and vice-versa. Be sure to adjust

this level to best suit the strength with which you strike the pad, your desired dynamic range (i.e., the difference between

loudest and quietest volumes), and the type of DTX Series drum trigger module being used. If the level adjustment knob is

turned all the way up but the output level is still low, raise the DTX Series Drum Trigger Module’s input level using the Gain

parameter from the trigger area.

If playing fortissimo (ff) passages with the KP90 connected to a DTX Series drum trigger module, the gain level

on the module’s trigger setup screen should be adjusted to between 90% and 95% of the displayed input level.

For more details, refer to the Owner’s Manual that came with the drum trigger module. Excessively large output

levels can have unintended consequences such as a reduced dynamic range and double triggering (where a sin-

gle strike produces two distinct sounds).

No sound is produced or the volume is too low.

 Ensure that the KP90 is correctly connected to a DTX Series drum trigger module using the stereo phone cable pro-

vided. (See Making Connections.)

 Check the pad’s output level. If this level is too low, use the level adjuster to increase it. (See Adjusting the Output Level.)

 If no sound is produced when the pad is struck softly, lower the setting of the Minimum Level parameter from the mod-

ule’s trigger area.

 Check that the base’s position is adjusted so that the beater hits the center of the pad correctly. (See Assembling the

KP90.)

Two or more sounds are produced in response to a single strike (i.e., double-triggering).

 Check the pad’s output level. If this level is too high, use the level adjuster to reduce it. Note that triggering of two or

more sounds occurs when the output level is excessively high due to the fact that the signal being input into the drum

trigger module remains large for a relatively long period of time. (See Adjusting the Output Level.)

For more troubleshooting tips, refer to the Owner’s Manual that came with the DTX Series drum trigger module. If

you still cannot find the information you need to resolve a problem, please contact your Yamaha dealer or the cus-

tomer support center indicated at the end of this manual for assistance.
