The rise time is not fast enough to catch the peak of the gunshot, it will catch the trailing end.Josh-PTP wrote:Bendersquint wrote:No that would not be accurate, not fast enough rise.
ok I'm a little db meter dumb... but all the specs seem to be compatible.. what am I missing?

Reading through my old 2209 manual, I noticed that it mentioned that the standard min rise time of 20 microseconds could actually be reduced to as little as 5 microseconds with minor internal alterations, and it suggests contacting B&K to talk with them about it.Bendersquint wrote:The rise time is not fast enough to catch the peak of the gunshot, it will catch the trailing end.Josh-PTP wrote:Bendersquint wrote:No that would not be accurate, not fast enough rise.

It very well may, B&K can probably answer that question.Tony M. wrote: Would it increase measured SPL from a gunshot?
The LD is easier to use than the BK2209.unclemoak wrote:I finally got my 800b in the mail today. Although I haven't yet found the correct mic for it, I must say I'm thoroughly confused on how to use it. Looks like I'll be spending the next couple days reading the instruction manual.
Hopefully the B&K I have on the way is a little easier to use than this thing.
Any tips or pointers to get either unit up and running?Bendersquint wrote:The LD is easier to use than the BK2209.unclemoak wrote:I finally got my 800b in the mail today.

Does anyone think such a modification would actually be beneficial?
Would it increase measured SPL from a gunshot?
Since they won't work on it anymore, see if they will provide a complete set of circuit diagrams so you can have qualified service personnel work on it. That would be incredibly helpful.unclemoak wrote: ...

The concern is that we would go into the unit, modify it and then something else would fail as the 2209 is famous for this issue, (or rather infamous for). My apologies. I wish we could help on this one, but we can’t. Please let me know if there is anything else I can assist you with."
Yes, the LD800B is one of the 2 meters that exist to give mil-spec results.Josh-PTP wrote:What about a Larson Davis 800b meter? Would this be fast enough to catch the peak of the sound? Also what microphone would you need for this?
Thanks for the help.
Neither company will release circuit diagrams or blueprints for their products, even the ones retired decades ago.srs wrote:Since they won't work on it anymore, see if they will provide a complete set of circuit diagrams so you can have qualified service personnel work on it.
