Zoom H1 XLR 2-Channel 32-Bit Float Audio Recorder

The Zoom H1 XLR is a compact two-channel recorder designed for capturing microphones, instruments, mixer feeds, and other audio sources away from a studio. It provides two locking XLR/TRS combo inputs alongside a 3.5 mm stereo mic/line input for flexible source connection. Its portable format suits musicians, filmmakers, podcasters, and creators who need a dedicated recorder with professional-style input options.

32-bit float WAV recording and dual A/D converter circuits are central to the H1 XLR design. This approach gives recordings broad usable dynamic range and removes the need for conventional input-gain adjustment on the XLR/TRS inputs. Recording is available at 44.1, 48, or 96 kHz in stereo or mono.

Its two combo inputs accept XLR or 1/4-inch TRS connections, with individual hardware mic/line level switches. The recorder can accept microphone-level sources or professional line-level feeds up to +24 dBu in line mode. It also supplies +48 V phantom power for compatible condenser microphones and 2.5 V plug-in power through its stereo mini input.

The 128 x 64 OLED display includes a real-time waveform view to help monitor recording activity. A built-in mixer allows adjustment of each track's input level, while the 3.5 mm phone/line output supports headphone monitoring or connection to a camera. An onboard speaker provides quick playback reference without requiring headphones.

The H1 XLR records directly to compatible microSDHC and microSDXC cards, with support up to 1 TB. Its USB-C connection also enables a 2-in/2-out USB audio interface for computers and compatible mobile devices, including simultaneous SD-card recording. Power can come from two AA batteries, USB bus power, an external USB battery pack, or the optional Zoom AD-17 AC adapter.

Design & Installation

The H1 XLR is a handheld recorder with a 128 x 64 OLED display, physical controls, locking combo input connectors, and a built-in 20 mm by 30 mm elliptical dynamic speaker.
