Triggering the Dual-Zone Crash and Hi Hat Cymbals
The Smartrigger crash and hi hat cymbals use what is commonly called a “Head/Rim” or
“Piezo/Rim-switch” type of triggering system. This means that the first “zone” or sound can be
triggered by activating the piezo trigger (which is mounted inside the small black housing
underneath the cymbal) and the second “zone” or sound can be triggered by activating the
piezo trigger and the rim-switch at the same time. The “rim-switch” is the 180 degree gold
colored band under the cymbal. This is also the “choke” switch that causes a ringing cymbal
sound to be “choked” off or stopped, by striking the cymbal then grabbing the choke switch.
To trigger the Head sound, strike the cymbal’s surface with the tip of the stick.
To trigger the Rim sound, strike the cymbal’s edge with a glancing blow
To choke the crash cymbal sound, strike the cymbal then grab the edge of the cymbal.
