SIX TRACKS. POCKET-SIZED.
PR-4 is a compact, foward-facing recorder for doc, ENG, and video creator workflows—delivering 32-bit float performance, 4 inputs / 6 tracks, wired SMPTE LTC/ATC plus wireless timecode for DEITY’s ecosystem, and Sidus App control for integrated full wireless remote control.
Introducing the ReGain PreAmp™
The PR-4 features the brand new ReGain Preamps™, ultra-quiet microphone preamps that deliver up to 60 dB of gain, providing enough amplification to drive even demanding dynamic microphones without the need for external inline boosters.
Achieving an Equivalent Input Noise of -127 dBV (-125 dBu) represents a significant engineering accomplishment for the PR-4’s preamp design. Measured under A-weighted conditions at 60 dB gain with a 150 ohm source, this level of performance places the PR-4 firmly in professional territory, delivering an exceptionally low noise floor that preserves detail and clarity even with low-output microphones.
Introducing the VoiceAware Automix™
VoiceAware Automix™ intelligently manages multiple microphones in real time, dynamically prioritizing active voices while subtly reducing the presence of inactive channels. By continuously analyzing incoming signals, it maintains a clean and focused mix that minimizes ambient buildup and keeps dialogue clear and intelligible, even in multi-speaker environments.
The result, VoiceAware Automix™ creates a clean, well-balanced stereo reference mix for post-production, giving editors a helpful starting point.

True Dual Media
Using a dedicated recorder like the PR-4 with dual media recording helps protect against some of the most common data-loss scenarios in production. SD cards can be lost, corrupted, or accidentally formatted during a busy shoot or when offloading media at the end of the day. By recording simultaneously to both an SD card (up to 1TB) and the internal 64GB SSD, the PR-4 provides a built-in safety net, ensuring there is always a second copy of your audio even if something happens to the primary card.
We also allow you to record different signals to each media format. Client ask for just a stereo file? You can still record the POLY file as a backup… just in case.
+8 Hrs Battery Life
The PR-4 runs on rechargeable power.
The PR-4 features an internal NP-F550 battery bay that can be recharged via the USB-C port on the side of the unit. It also can just run off the USB-C port if you want, making external power options cheap and readily available.
For the professional looking to integrate the PR-4 into a bigger setup, there is a 4-Pin Push Pull Power port on the other side of the unit that is compatible with the SPD-1, SPD-Mini, or can be fed direct power form the S-95 using the SPD-HRBatt. It too can also be used to recharge the internal L-series battery.
Introducing LiveHit DeNoiser™
LiveHit DeNoiser is designed to prioritize intelligibility in real-world recording conditions by actively shaping the audio signal around the human voice. And it does all that without adding measurable latency to your audio.
It focuses on reducing ambient distractions like traffic, wind, and environmental rumble while preserving the core presence and clarity of the speaker. The result is a reporter’s microphone track that cuts through the mix, helping operators capture usable dialogue even when live broadcast in uncontrolled environments.

World’s First Recorder to Natively Wirelessly Sync A Timecode Boxes & Slate
The goal has always been for the recorder to be the TC master source on a video shot, now it truly is.
The PR-4 is able to act as the master timecode generator for a small production team. Through our wireless timecode protocol, the PR-4 is able transmit it’s timecode to our entire timecode ecosystem of devices:
- DBTX Transmitter
- DXTX XLR Transmitter
- DLTX Lemo 48V Transmitter
- PR-2 Pocket Recorder
- PR-2ii Pocket Recorder
- TC-1 Timecode Box
- TC-SL1 Timecode Slate
And of course… other PR-4 units
The PR-4 also features a 3.5mm TC I/O port. Timecode jam a camera and other gear with SMPTE LTC/ATC.
Accuracy target: <1 frame / 48 h.
Or wirelessly sync using via the Sidus Audio App.

Accessories
Field Audio Bag (Mini)
The Deity Deity Field Audio Bag (Mini) is a compact field audio bag designed specifically for the PR-4 recorder, giving sound mixers a lightweight way to build a portable multichannel recording rig. Built from durable rip-stop nylon, the bag provides the strength needed for location work while incorporating comfort and design details for fast-moving productions.
The bag features an all-around zipper design, allowing quick access to the left and right sides of the recorder for cable routing while also opening underneath the bag to access the SD card slot and NP-F battery without removing the recorder. This layout makes it easy to swap media or batteries between shooting days while keeping the recorder fully mounted in the bag.
Inside the bag, a metal support frame and internal sub-chassis give the bag structure and help separate the recorder from the accessory pouch, keeping gear organized while protecting the recorder during transport and use. The entire interior is lined with soft Velcro-compatible felt, allowing users to customize the interior with hook-and-loop mounted accessories.
Build Different; Think Outside the Audio Bag
When developing the PR-4 we wanted to improve every aspect of the experience, even how it mounts. After years of having items spin in place when screwed into camera cages or on rigs, we knew basic 1/4″ mounts weren’t going to cut it. Under and on top of the PR-4 are dual Arri-Style 1/4″ 20 mounts with locating-pins.
Now when you mount the PR-4 onto a camera cage, you know it will be truly secured to the cage. And when you go to add accessories on top of it, those accessories are budging either.
The cage also features a built-in ORTF microphone layout, allowing users to quickly mount a matched pair of microphones in the correct stereo configuration without needing separate bars or adapters. By integrating these mounting points directly into the frame, the PR-4 can be transformed into a fast stereo recording solution for ambience, sound effects, and field recording. This design keeps setups compact, repeatable, and easy to deploy in the field.
We expect units to start shipping mid~May.
