The Zoom R8 Multitrack SD Recorder Controller and Interface is everything you need to start recording today! Zoom takes the turbocharged design of the R24 and reduces the footprint for a portable, powerful music production solution. Like its predecessor, the Zoom R8 combines four production tools in one incredibly versatile device. In addition to being a multitrack recorder with 8-track playback and 2-track simultaneous recording using SD memory cards, the R8 is an audio interface, a control surface and a pad sampler.
