The professional Zoom F8n Pro multi-track field recorder comes kitted out with eight microphone/line inputs and two SD card slots able to handle up to 1TB of data storage, supporting 32 bit float recording and a near-infinite dynamic range whether working on set or on location, and whether capturing action or folie. A stack of features, functions and post-production tools come built in, including a high-pass filter per channel, polarity inversion, and instant M-S to L-R stereo conversion. The Automix function is another highlight, especially if you're recording multiple speakers, each with their own microphone, since it will automatically adjust the channel volume and mute channels whenever someone stops speaking.
