The Yamaha DTS70 drum trigger system is designed to be the control center for any electronic drum system. The twelve, 1/4-inch trigger inputs on the back can accomodate many different input sources through adjustment of the three-position input level switches on the back, through the internal software, or a combination of the two.

Each input can be routed to sophisticated MIDI circuitry, or its own fast, dynamic trigger output. Once the analog input has been converted to the digital domain, the DTS70's processing power delivers the fastest possible conversion to MIDI, allowing accurate triggering from acoustic drums or electronic pads. As stated by Yamaha in an advertisement, the DTS70 was designed for and tested by leading drummers such as Dave Weckl and J.R. Robinson.
