A battery you can replace yourself

A battery you can replace yourself

Two screws and a standard NP-F pack. When it stops holding charge in four years, you buy a battery, not a recorder. Hardware you can open is hardware you can keep.

Five things you notice in the first week.

Knobs you can find in the dark.

WAV and a text log.

Four files and a plain log per take. Nothing to convert, nothing to unlock.

Why 32 bit float

Set the gain wrong and the take still survives.

Two converters, one quiet and one loud, written into one file. Clipping in the room does not become clipping in the file. You stop riding the knob and start listening to the scene.

Full specification

Five things in the box, and nothing you have to buy to start.

No SD card, because everyone has one and nobody wants ours. No manual, because the quick card is two sides and the menu is four items deep at most.

Three people who had one for a month.

Review units went out in September. Nobody was paid and nobody saw the copy before it ran.

“The first recorder in this bracket where I never opened a menu during a shoot. That is the whole review.”

Priya Raman

Field Recording Weekly · October

“Fourteen hours is real. I ran two of them on a five day documentary and charged once, on the flight home.”

Tobias Hein

“Two XLR is two XLR. If you need four you need the Pro, and they are honest about that instead of burying it.”

If we are late

Tooling is finished and the pilot run is done, so March is a date we expect to keep. If it slips, you get an email with the new date and the reason on the day we know, not at the end of the month. If it slips by more than eight weeks, we cancel your order and charge nothing unless you tell us to keep it.
