What’s on the body.

Six controls you’ll actually use, nothing you won’t. Every one works with gloves on.
01

Rotatable X/Y capsules

Matched cardioid pair that clicks between 90° for focus and 120° for width.
02

1.9″ daylight OLED

Levels, timecode and battery at a glance, readable in direct sun.
03

One-press record

A recessed button with a two-step lock, so a bag can’t start or stop a take.
04

Multi-function dial

Scroll menus, set monitoring level, or nudge a channel without looking.
05

Four combo inputs

Locking XLR/TRS on the sides, each with 48V phantom and a pad.
06

USB-C everything

Power, file transfer and 4-in/2-out audio interface mode on one port.

Why 32-bit float.

A fixed 24-bit file stops at 0 dBFS — anything louder is flattened for good. A 32-bit float file keeps going. The KT-4 records both converters at once and stitches them together, so the loud part survives and the quiet part stays clean.

24-bit fixed
Clipped
Peaks above full scale are cut flat. No plug-in can bring them back.
32-bit float
Recovered
Same take, pulled down 3 dB in post. Every transient is still there.
