According to Yamaha…..
A newly developed 7.5-inch rubber Snare/Tom pad with 3-zones and a shape that is compact but easy to hit. Through the experience of developing Yamaha’s well-known DTX-PAD, this rubber pad provides much greater playability. It features a softer head to provide moderate bounce, and the surface is not slippery to give a more natural feeling when playing with sticks. The pad is divided into 3-zones and supports open and closed rimshots when used with a compatible DTX trigger input*. This pad makes a perfect snare upgrade for the DTX400K. In addition, you can assign different voices to different zones (DTX500/700/900/M12 only). This makes highly original performances possible. For example, you can create an acoustic drum sound when you hit the head area, a cowbell sound when you hit the open rim area, and a loop sound when you hit the closed rim area.
Before you purchase a pad, refer to the pad compatibility table to make sure that you can connect the pad to your drum trigger module (tone generator).
Standard-equipped on the following DTX drums: DTX450K
