Essential Information About the FLOW 4V Digital Mixer
- 10-channel field recorder and 8-channel digital mixer: designed for sound for picture, documentary, broadcast, and mobile recording.
- 32-bit float recording on SD card and via class-compliant USB audio interface: high level safety and gain recoverable in post-production.
- 4 Midas mic preamps with phantom power and dual-stage A/D conversion for low noise and wide dynamic range.
- Wireless remote control (FLOW 4V MIX app for iOS/Android via Bluetooth LE), plus automix up to 8 channels for clean and stable dialogue.
FLOW Series: a modern recorder-mixer at the heart of a field workflow
The
FLOW 4V is part of the
FLOW Series with a very current approach to mobile sound: reducing adjustment constraints during recording (gain management), securing capture (pre-record, automatic copying), and streamlining integration into a video chain (triggering via HDMI, timecode, mobile control). It positions itself as a compact solution combining
mixing,
multitrack recording, and
USB audio interface, to quickly move from shooting to editing or broadcasting.
A tool tailored for video sound recording, interviews, and multicam
The FLOW 4V targets content creators, camera operators, sound engineers, lightweight crews, and mobile control rooms who need a
reliable recorder and a
complete mixer without bulk. The
4 mic inputs with phantom power allow powering shotgun, static, or lavalier microphones via receiver, while recording
up to 10 channels ensures real flexibility (mix plus isolated tracks depending on workflow). On set, remote control via smartphone is especially useful when the device is mounted under a camera, on a tripod, or placed near talent to optimize cable lengths.
Key features: level safety, advanced mixing, and field-oriented connectivity
32-bit float and dual-stage conversion: clean capture without gain stress
Thanks to
32-bit float recording and
dual-stage conversion, the FLOW 4V limits situations where a bad gain setting ruins a take. The idea is simple: the capture tolerates large level variations, and you can
readjust gain in post-production on float recordings. This is a major asset for unpredictable interviews, reports, or scenes where microphone distances vary. For more classic workflows, the device also offers
24-bit fixed point recording.
Midas preamps, low noise, and high headroom
The
4 Midas mic preamps are designed to deliver a clean, detailed, and usable sound, with
phantom power and an architecture focused on
ultra-low noise and
high headroom. Whether capturing spoken voices, ambience, or more dynamic sources, you benefit from a solid foundation for professional sound recording at 48 kHz.
Complete 8-channel mixer: fine control even in a compact setup
Beyond recording, the FLOW 4V operates as an
8-channel digital mixer with essential tools to shape the signal:
level,
pan,
low-cut,
tone,
high-cut, and
dynamics. You can quickly clean handling noises, tame sibilance or resonances, and stabilize voice levels before headphone send or line output.
Automix up to 8 channels: clearer dialogue without aggressive pumping
The device offers automix up to
8 channels based on a smooth
gain-sharing algorithm. In practice, this helps keep speech in the foreground and reduces ambient noise buildup when multiple microphones remain open-a real plus for roundtables, conferences, filmed podcasts, or multi-speaker interviews.
Field functions: pre-record, backup, and sync
To avoid missing the decisive moment, a
pre-record buffer captures what happens just before pressing REC. Once recording stops, files on SD can be
automatically copied to a connected USB drive to reduce loss risk and speed up transfer. For synchronization, the FLOW 4V can
generate internal SMPTE timecode and has a stereo auxiliary input that can also receive a
SMPTE clock to align the internal clock.
Video integration and remote control
In camera setups, the FLOW 4V can receive a
CEC signal via HDMI to
trigger audio recording from a compatible camera. On the set communication side, it can also receive
Bluetooth audio from a mobile device, useful for
talkback or reference playback. Finally, the
FLOW 4V MIX app (iOS/Android) provides remote control via
Bluetooth LE, ideal for adjusting a mix, checking levels, or starting a take without touching the device.
StageConnect: multichannel audio with ultra-low latency and possible expansion
The FLOW 4V integrates
StageConnect for uncompressed multichannel audio transmission with
sub-millisecond latency via a standard XLR/DMX cable. To go further, the optional
StageConnect FLOW 4VIO adds
4 additional mic inputs,
2 headphone outputs, and remote power, useful when the shoot evolves to more microphones and more returns.
