Zoom’s team of engineers are musicians, and they designed the R4 with the needs of fellow musicians in mind. The R4 boasts a dedicated ‘bounce track’ and 32-bit float recording, making it the perfect tool for capturing yZoom’s most ambitious compositions.

Record, Bounce, Repeat
With the R4, you can record up to fZoom’s tracks, mix, and bounce them to the dedicated ‘bounce track.’ This lets you free up additional tracks to keep adding layers. What's more, you can choose to do a quick bounce or mix and bounce in real-time. Plus, the R4 allows you to undo yZoom’s last bounce if you're not satisfied with the results.

32-Bit Float Recording
The R4 captures perfect audio with every take, without the need to set gain.

Combo Inputs
The R4 features 2 XLR/TS combo inputs with legendary Zoom preamps. You can plug in microphones, instruments, keyboards, and more.

Track Effects
Each track features a 3-band EQ, pan, echo, and reverb to refine yZoom’s mix.

Input Effects
Apply effects to input A, such as amp simulations, delays, distortions, and more.

Built-In Microphone
The R4 also features a high-quality built-in microphone, perfect for acoustic guitars, vocals, or capturing a quick reference recording.

Much More Than A Metronome
The R4 comes preloaded with a rhythm section of over 80 different drum patterns to play along with. Genres include rock, hip hop, funk, heavy metal, and more.

Every Take Is Saved
Tracks that you record are automatically saved individually, even after they have been bounced.

32-Bit Float Audio Interface
The R4 is also a powerful 2-in/ 2-out USB audio interface with 32-bit float technology. Connect it to either yZoom’s computer or smartphone.

Control and Create
With a fader for each track and dedicated hardware buttons for the most used functions, you won’t need to menu dive to record yZoom’s music.

Powered For YZoom’s Ideas
The R4 can be powered by 4 AA batteries or through its USB-C port.
