The Zoom H4essential is a portable four-track audio recorder that combines advanced recording technology, versatility, and intuitive operation in a compact, lightweight design. Whether capturing music, podcasts, or audio-for-video, its 32-bit float recording ensures flawless sound quality without the need for manual gain adjustments. Dual onboard X/Y microphones handle up to 130dB SPL (equivalent to the volume of a live Rock concert) while two XLR/jack combo inputs with locking sockets and phantom power accommodate condenser mics and line-level signals. A 3.5mm mic/line input adds flexibility for lavalier microphones or other sources. Recordings can be saved in WAV, BWF, or iXML formats at resolutions up to 96kHz, and stored on microSDXC cards up to 1TB. Weighing just 226g, it offers flexible power options: Up to 19 hours on two AA batteries in two-track mode (eight hours in four-track mode), USB-C bus power, or the optional Zoom AD-17 adapter. For enhanced accessibility, selected menu functions can be read aloud - an invaluable feature for visually impaired users. Optional accessories also enable timecode synchronisation via Bluetooth. The Zoom H4essential's colour LCD and tactile controls further simplify operation, allowing users to focus on their task with ease.
At the heart of the Zoom H4essential is its 32-bit float recording technology, which allows pristine audio to be captured and eliminates the need to set gain levels, ensuring distortion-free recordings with an exceptional dynamic range. The X/Y microphones capture everything from delicate whispers to thunderous performances, while the XLR/jack combo inputs - complete with phantom power - support professional condenser microphones. Dual A/D converters read billions of amplitude values, allowing adjustments in post-production without compromising audio quality. Peaks can be tamed, quieter sections amplified, and all nuances preserved. Whether recording in the field or streaming live, the USB-C connection turns the H4essential into a high-speed USB 2.0 audio interface, supporting both live and studio applications.
The H4essential caters to the diverse needs of musicians, podcasters, and streamers. Musicians can record - in stereo and on the fly - live performances and rehearsals in the loudest environments and even split a couple of extra tracks off the mixer, if required. The two XLR/jack combo inputs support any combination of microphones, including lavaliers and canon mics, while the line output can connect directly to a camera to synchronise audio with video. Podcasters can create interviews with a stereo ambiance track to use at the editing stage, and streamers can take advantage of the H4essential's 4-in/2-out USB audio interface, streaming 32-bit float audio and simultaneously recording it to an SD card. Quick reference playback is possible thanks to the built-in speaker, and a dedicated headphone output ensures accurate monitoring. With these powerful features, the H4essential appeals to a wide range of content creators across many disciplines.
Founded in 1983, the Japanese company Zoom manufactures a variety of audio equipment, including a range of portable "handy" recorders as well as multi-effects processors, effects pedals, drum machines, and samplers. Over the past thirty years, the company has built a reputation for producing innovative yet affordable products based on original microchip designs. Since the Zoom-9002 (an ultra-compact multi-effects processor that can be attached to a guitar strap) was introduced in 1990, Zoom has become one of the leaders in digital audio processing.
Compact, durable, and designed for portability, the Zoom H4essential thrives in both studio and outdoor environments. Its onboard X/Y microphones capture detailed soundscapes, ideal for interviews, nature recording, or live events. The 3.5mm mic/line input provides additional flexibility for lavalier microphones, while the optional BTA-1 adapter enables Bluetooth timecode synchronisation, streamlining audio-video integration for filmmakers. A threaded mount fits easily onto any camera rig or stand, and optional accessories such as the Zoom HRM-7 holder and the WSU-1 windscreen further expand functionality. The H4essential's flexible power options include USB-C bus power, the Zoom AD-17 adapter, or two AA batteries for up to 19 hours of operation in two-track mode, ideal for extended recording sessions.
32-bit float recording technology
Who hasn’t experienced a perfect take being ruined by digital clipping? This is where 32-bit float technology redefines recording, offering two key advantages: Its extended dynamic range, which reads up to four trillion amplitude values (i.e. 33% more than traditional 24-bit technology), captures both the softest and loudest signals without clipping, ensuring that recordings remain clean, even under extreme conditions. Peaks can be reduced, quieter sections amplified, and audio quality is preserved entirely for post-production. There is no need to adjust gain levels either - the user simply presses record, and the H4essential ensures that every take is captured with precision and clarity.
