Topic: Zoom F3 Part 2

[grawk]

What are people transferring their files into? Soundforge, audacity?

Basically everything supports 32 bit float these days, so whatever you like.

Ran mine last night with the MK21s and NBox Platinum for Daniel Donato's Cosmic Country set.  Nice rig without metal detectors.

Haven't read too much about 32bit float or this recorder before today.  Reading about this recorder, I get all teary-eyed thinking back to all of the  shows that I messed up when I first started taping back in the early to mid-90s, shows like the Robillard/Bangham years of the TBirds lineup, Luther Allison, Johnny Clyde Copeland (both of whom died in 1997), the Danny Morris years of the Nighthawks, Johnny Winter, and on and on. 

Sooo many of those guys are dead now....what I wouldn't have given to have today's gear back then so that those recordings would have turned out.

what batteries you using - i know you dont like rechargables
fyi for getting in the door i been using your key fob in dish mehtod - i just tell them f3 is my car stereo and they just go ok

so was thinking of the f3 for low profile. I saw some old posts about removing the steel cage. is that an option?

[audBall]

^ Yes, it can be removed fully intact. It sheds half of the total weight. See my post at the top of the previous page.

thanks found it.  so you need to take the f3 itself apart in order to unscrew the front of the cage, and then run bolts through the front faceplate, from the inside, to hold it all together properly? if im understanding correctly

I use engergizer lithiums.  last all day.

If you want to take it to that extent, then yes. It required me to fully disassemble, because the cage is bolted to the inner molded face. That's why I had to add that tiny nut to the face to hold the through-bolt that keeps the 4 buttons/PCB in place - it would normally screw into the metal face.

Another TSer kicked off this effort in a different route (see older posts) that appears to retain a portion of the metal cage still affixed to those bolts.

Please also note that I approached mine in a "quick and dirty" fashion, fully aware of any potential warranty loss. This thing has dozens of tiny bolts holding the innards together, but really only a fraction were required to reassemble to my liking/needs. It's kind of amazing and hard to believe how tiny and light this is. XLRs aside, it could almost fit in a 5th pocket. At least in some old JNCOs.

Bit of a stab in the dark here......
 
Does anyone know the upper frequency limit of the F3 'line out' jack when the device is used at 192KHz sampling? .....  It's not in the manual, and Zoom haven't been able to help so far.

I'm interested in using a Zoom F3 to record ultrasound at around 50KHz......
Zoom have confirmed to me the actual unit frequency response  is +0.5dB/ -1dB @ 60KHz, but  are unable to advise whether that upper limit applies to the line out socket as well...
I can understand the headphone output being upper frequency limited, but hopefully not the line out socket.

I currently use the line out from my Tacam DR100Mk3  to monitor ultrasound recordings in real tme - via a custom heterodyne  monitor device - and that works fine.
I'm hoping the F3 will allow me to do the same.
But that depends on the upper frequency limit of the line out jack........

You could test this yourself by using any number of online test tone generators to make an ultrasonic tone sweep. Put that file on your F3 memory card, play the file, and monitor the output.

EDIT: You can just download the 192 kHz sweep from here:

Thanks for your reply.  Sadly I don't have an F3 to check that.
 
I'm only going to buy one if the 'live' line out response extends to at least 60KHz during recording ( which is what I understand is the upper frequency limit of the F3  @ 192 KHz sampling ).

I suppose you could see if there's somebody else at Zoom tech support who could find out the answer for you. I suspect that they have not tested the line out on this unit very rigorously. On a recorder this inexpensive, they are putting all of their money into the mic preamps and ADC, and the analog output stage is likely comprised of cheaper components.

Looks like neither F3 line out or headphone output are bandwidth limited. First sweep is line out and second sweep headphone out to F6 (the line out clipped the F6 inputs but still shows that the swap file played all the way through).

I do have a second request in with Zoom Support, but they don't currently have the answer ... thanks for you reply.
