Zoom F6

I use this to record live music in multichannel to mix in the box post event.

32 Bit float allows me to focus on mic setup and placement and not have to worry about setting levels or gains on the device as in the DAW it is magical to see peaks which look clipped but when normalised are absolutely perfect.

Simply cannot go back to 24bit recorders now :/ This tech should be in everything that records audio!

One personal negative issue is that 6 inputs is just not quiet enough for my use-case. Really wish Zoom made a 12 XLR input version of this. It would be end-game for sure.

So to get around the 6 input issue, I now use two of these in a master/slave relation so hit record on master and both start recording so no sync issues in post! If you want to do this.....use the Timecode input/output port for the master using a TRS cable and then use a TRS to Mono converter on the slave port. Adjust the settings in the menus for the slave to accept timecode from the port and then watch the timecode sync to the master and hit record and see the red lights on both go on ^^....you're welcome.

I will list the good and bad aspects of the Zoom F6 but will note that overall I think this is a great device. For context, I am coming from a Zoom F4 but I have experience with most of Zoom's devices.

Good:
- Amazing amount crammed into a tiny package. In particular the six XLR inputs.
- 32-bit float
- Very quiet and transparent mic preamps. These seem to be the same as those that are in the F8n Pro and the F3. The ones in the F4 seemed to be slightly different at 192 kHz (although this might be more to do with the anti-aliasing filters).
- Battery life of 4 x AA batteries is surprisingly good. I am coming from the Zoom F4 which uses 8 AAs and have found the efficiency of the F6 much improved. As an example, I recorded 2 x Lewitt LCT540s large diaphragm mics (phantom power at 3.6 mA) at 192 kHz and 32-bit float for over 3 hours before the batteries gave out. If you reduced the sample rate you could expect to record for much longer. I was using 4 x Energiser rechargeables rated at 2300 mAh each.
- Built-in NPF/L-series battery caddy avoiding the need for external powerbanks connected via cables. It can still be powered by USB and a powerbank if you prefer though (no hirose). As the performance is so good on AAs, you might still consider that option if only recording for a few hours. If you have multiple powering options attached, the device is smart enough to swap between them automatically if one becomes exhausted.
- Can be bus powered, unlike the F8n Pro and F4.
- USB-C. The Zoom F8n Pro still uses mini USB; maybe there's a reason.
- Minijack headphone socket. While the 1/4" socket on the F4 and F8n might be regarded as professional, I would occasionally find myself in the field without the adapter.
- Rugged build. Lots of metal and the top and bottom panels extend out to protect the dials from damage and accidental movement. No sharp edges.
- Additional useful features such as trim linking, stereo linking, MS decoding and Ambisonics modes.

Bad:
- The user interface and interaction with menus and parameters is pretty horrible. This is to some extent unavoidable on account of the physical size of the device and the limited panel area. However, swapping the positions of the dials and the buttons so that the buttons were on the edges would facilitate operating using the thumbs, which would undoubtedly be an improvement.
- Navigating the menus with four buttons is slow and unintuitive. Regular use of the device is required to get used to this. A combo jog-wheel and button as in the H4n might have offered improved interaction. Perhaps the six dials could have also functioned as press switches to serve as menu shortcuts.
- In interface mode, it is not possible to use the physical dials to adjust trim levels. To adjust trim levels you have to dive through several menus and adjust each individually using the two tiny up/down buttons. This has been made slightly less of a problem now that firmware 2.0 allows operation at 32-bit float in interface mode, but having the dials as trim controls in interface mode, at least as an option, would greatly increase the versatility of this device.
- This one is quite niche, but I was trying to use the F6 as a sound file player with some music tracks I had created elsewhere, but it would only read certain files. Even after investigating formats and file naming I could not surmise its rationale. This issue has been raised by others and Zoom's response was: the Zoom F6 is not intended as a sound file player.
- No jack inputs. The connectors are XLR only, not combo XLR/jack inputs. For line level input you need to use XLR and make the change in the device's software. Admittedly, combo connectors wouldn't fit with the battery block in the middle of the device.
- SD card slot on the bottom, underneath the L-battery (if attached) so changing the card involves removing this battery. Again, this is somewhat understandable given the small size of the device, but I would happily have sacrificed the Bluetooth dongle socket to have the SD card slot on the side!

Things I can't comment on as I don't use them but that may be useful to you:
- Bluetooth operation.
- Timecode
- Automix (useful when recording conferences)
- LR mix recording
- The limiters

In summary I highly recommend this device for travelling field recordists for whom compactness and a large number of mic inputs are requirements. For film-makers and people for whom size and weight are not so critical and better ergonomics and UI are desired, you might consider the Zoom F8n Pro.

We use this soundcard primarily for our acoustic testing projects. We can easily carry this to the field as opposed to my other bulky soundcards and laptop etc. The 32-bit floating is a huge blessing which my other sound-cards can do. We test rooms with balloon pops as a backup measurement along with our other more elaborate measurements. While with my other soundcards I have to adjust the gain every single time, with the Zoom F6 I don't have to, since the 32bit ADC has a higher range of measurements and the audio will not clip!
Moreover increasing the gain later on while processing the audio does not induce a lot of noise thanks to the extremely low self noise.

Pros - Very low noise, 32 bit ADC's, Hit record and not worry about anything else!
Cons - USB interface with PC is quite underwhelming. UI is a bit confusing.

As a single man shooter, the F6 appealed to me straight away with the 32bit float, small form factor and sled at the back for SONY batteries. This means I can shoot all day and not worry constantly about my audio clipping or AA batteries dying on me.

The 6 inputs are very powerful, capable of powering the SHURE SM7B.

Overall it's incredible and you shouldn't hesitate to buy it.

Handling wise has been zero issues. I hear people complaining about the size of the knobs for the inputs but they aer completely fine. I'm 194cm tall with large hands and have had zero issues.

Delighted I bought it, its a joy to use and makes my life so much easier on film days.

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!

considering it's size it's quite versatile. Only The knobs are a bit fiddly, but there is an app or mix panel if you need more robust control. Love the fact that you can record at 32 bit recording in 192 khz, perfect for my foley recordings... and amazing fact for this price range. That with the dual preamps make it so clipping is really no more problem if you run into it at some unexpected moment. 6 inputs is more then enough for most of my cases. I love the fact that there is build in timecode generator, so i can sync it up perfectly with video if i need to. You can buy a jack to BNC cable to drive a professional GenLock system like we did in our studio. Plenty of battery options provided, incl usb C. Menu is easy enough. I did wish they put the full manual in, there was only a 'quick start' with very brief explanations of every function. For every semi-pro this is a no brainer for the cost in my opinion. Hope they bring out an android app as it's only Mac which honestly blows my mind.

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'.

The F6 is a great recorder for the price. The features are many, but it lacks in some fields: the slope signal that can be used for syncing in post can't be automated. It's there, but I can't go in a submenu every time I have to record audio that has to be synced in post. I know it has Timecode, but I can't use it without buying other expensive gear to use with my prosumer camera. Even the Tascam Dr100MkIII has this feature that solves so many quirks and problems that I couldn't justify the fact that is a thing is there but is unusable because can't be automated. The line out can produce an audible hiss in cameras that doesn't support line level input. The only workaround is to use a 35db attenuator cable that is really hard to find in online stores.
Overall the great feature of this recorder is a little obscured by its faults, but is a good starting point to do better in the future, maybe an H6 version of this, more portable, with an automated slope signal and an attenuable line out for prosumer cameras will be a no brainer, an instant best of.

I did a whole a cappella album with this little device. The result was perfectly fine.
The best feature is the ability to record in 32-bit float which gives extremely wide dynamic range and virtually you cannot clip your recordings.

The weakest part is the headphone amp which Zoom did not improve even on their latest F8n Pro edition.

Keep in mind that F6 has 6 mic inputs, but they are only XLR (no combo) therefore it’s not ready to plugin instruments directly via quarter jacks.

Overall, for it’s price and sound quality, this little device is an absolute bargain.
