The DEITY PR-4 is a compact field recorder built for video and production sound, with 32-bit float recording, internal timecode, and a wide range of power options. In this review, we look at what it offers and how it compares with the Zoom F3, Tascam FR-AV2, and Sound Devices MixPre-3 II. The recorder and accessories were provided free for testing, with no input on the review.
What the DEITY PR-4 offers
The PR-4 records 24-bit, 32-bit linear, or 32-bit float audio at 48, 96, or 192 kHz. It has two XLR/TRS combo inputs, a 3.5 mm stereo input, and support for AES3 and AES42 digital sources. You can link the main inputs for stereo or mid-side recording.
Its preamps also tested quietly. In a self-noise test, the recorder measured an RMS maximum of -128 dBFS at zero gain. Even with substantial gain applied, the preamp noise was not considered a concern for dialogue recording.
For recording media, the PR-4 can write to an SD card and its built-in 64 GB SSD at the same time. That gives crews a second copy of a take without adding an external recorder. It also has a built-in timecode generator, with wired timecode input and output and wireless syncing with compatible DEITY equipment. During a test lasting seven hours and 37 minutes at room temperature, no timecode drift was observed.
Power, controls, and onboard tools
Power is a standout feature. The PR-4 takes a replaceable NP-F550 battery, USB-C power delivery, or four-pin Hirose power. USB-C and Hirose can also charge the internal battery. With two phantom-powered microphones connected, the tested battery lasted 7 hours and 37 minutes.
The recorder includes automix, EQ, a limiter, and up to 6 dB of noise reduction. Early automix testing suggested it could be useful for podcast conversations, especially with close microphones and thoughtful placement, though it struggled when two speakers sat shoulder-to-shoulder. Noise reduction was subtle in testing and did not noticeably damage the dialogue.
The small OLED display has limited touch controls for quick actions, while physical knobs handle the main adjustments. The recorder can also send a stereo mix to a computer over USB, but it does not provide the flexible input and output routing of a full audio interface. For creators weighing recording gear and production workflows, that distinction matters: it works as a convenient USB feature, not necessarily as a desktop interface replacement.
How it compares with other recorders
The PR-4’s reviewed US price was $449. Its optional metal cage adds protection and mounting points, but the recorder’s knobs felt a little loose in testing.
Other drawbacks include a small screen with some hard-to-read color choices and a startup time of about 15 seconds with the SD card used in the review. It also lacks wireless audio monitoring, a feature found on the FR-AV2.
Which recorder makes sense?
The Zoom F3 remains a good choice if you want a small, simple, lower-cost 32-bit float recorder. The Tascam FR-AV2 may suit crews who value wireless monitoring and a larger display. The MixPre-3 II is still a strong option for people who need a tougher recorder, serviceability, a third input, or a more flexible computer interface.
For creators who want timecode, multiple power choices, backup recording media, and built-in production tools in a compact package, the DEITY PR-4 is a compelling alternative.
It does not make the others obsolete, and each can produce strong recordings. The right choice depends on which features will matter on your next shoot.
