Zoom R4 MultiTrak Portable SD Recorder Interface

The Zoom R4 MultiTrak is a portable 4-track digital recorder and 2-in/2-out audio interface that brings the spirit of classic cassette multitrack recorders into a modern, compact format. Recording at 48 kHz with 32-bit float resolution, the R4 captures audio with an extraordinarily wide dynamic range, virtually eliminating the risk of digital clipping. This means musicians can focus on performing rather than obsessing over input levels — any adjustments can be made after the fact without degradation. The two XLR/TS combo inputs accept microphones and line-level instruments, while the built-in microphone provides a quick-capture option for spontaneous ideas when external gear is not at hand.

The R4's dedicated bounce track is a standout workflow feature. After recording across the four main tracks, you can mix them down to the bounce track, freeing up all four original tracks for additional layering and overdubs. This technique, borrowed from the analog tape era, gives the R4 effectively more creative headroom than its 4-track spec might suggest. Four physical faders and a color screen with metering provide hands-on control over your mix, while over 80 built-in drum patterns supply rhythmic foundations for songwriting sessions. Recording to SD card keeps file management simple, and battery-powered operation means the R4 can travel anywhere — from a park bench to a backstage warm-up room. As a USB audio interface, it also integrates into DAW-based workflows when you are ready to move a project to the computer.
