Zoom F6

6 tracks in a space so compact. Mid / SIDE monitoring? Some years ago it was unconceivable! This quality recorder is a gem. Very good silent and clean preamps, it runs on various sources of power (including USB-C battery packs) and it can be mounted on top of a tripod or under a camera for light-weight video recording.
Defects? the knobs are tiny and crammed in a small space. Setting up gain levels on the fly without a (sold separately) controller can take time. It can be controlled via bluetooth, but only buying a separate adapter and the app is only for iPhone... and I have Android.
In short: quality? excellent. Ergonomics? may be better. Portability? Yes!

It is well made and a quality recorder.
Zoom's website lists 16.5 hours of battery life and the Youtube affiliates rave about such as well.
Of course you imagine it is the 4 x AA's that you only need to put in to power this F6. Not So. There is a very good reason they give you the option of adding an 'L' battery pack to this recorder.
Truth is with all other channels turned off and using just one mic needing phantom power. You will get not much more than a couple of hours use from the 4 x AA's. So you need to purchase the 'L' battery pack if you want serious recording time or using multiple mics and headphones.
Saying that it is a plug-in and go recorder. The Zoom F6 does everything for you with the 32bit facility. So apart from battery life, you only need to remember to press 'record'.
