The Yamaha EAD20 is an electronic acoustic drum module that combines microphones, cables and mixing in a single unit. It runs on the SWX100 sound engine, the same processing chip used in the Yamaha EAD50, and offers 512-note polyphony. It has 2,203 voices, 252 digital effects, and onboard looping and sampling.
A sensor unit clamps to the bass drum hoop. It contains a stereo condenser microphone built around Japanese-made custom capsules, which captures a stereo image of the whole kit. A built-in kick trigger turns each bass drum strike into a trigger signal, so samples can be layered in time with acoustic playing.
The module has six trigger inputs, with room for up to nine triggers using splitters. It works with single-zone, dual-zone, three-zone and multi-piezo pads, including non-Yamaha gear. An 8-in/10-out USB audio interface records multitrack audio to a computer, and MIDI out connects to a DAW. LED rotary faders and assignable Kit Modifier knobs adjust the sound while playing.
