after 35 years in that business you must know that 9v alkaline battery go down by voltage and finish its life when it 6 v under load , That's why all the equipment which use these or 1,5 v or any other have dc to dc converters and regulators , what in simple words for you, only the minimum voltage to power the circuit is what matter .
Not quite. Alkaline's are considered out at 5.4V. And you are right the minimum needed to power the circuit is what counts. Most old school 9V wireless mics for instance (with your 35 years you must remember them) wont work at all on standard rechargeable 9V because they start out at 7.2V. And no many devices don't use DC to DC converters and none did a few years back. In most cases there isn't really the need. Everything but the phantom power is easily powered from the streight batt power and one can get the 48V (though some don't bother with going all the way to 48V since that is not the spec but just the most common #) with voltage multiplying circuits. And again, depending on the circuit, battery powered boxes don't often need voltage regulators. So the question is, as you said what is the minimum needed to power the box. Traditionally, as you know, 7.2 has not been high enough.
----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------
I don't really give a shi* about old wireless or your annoying stories about the 5.4 v . we are talking about minimum voltage which in the case of shure is about 11 v
so 2- 7.2 v is 14 v more then enough .
now about mix pre which use allot of dc to dc converters and regulators to deal with minimum 1.7- 2v ( 2 dead alkaline ) and make it 15 for powering the electronics and 48 for microphones
the waist of power to supply accurate dc in % is huge , the lost may come to 20-25 % of the battery capacity . and probably one of the problems to supply enough to schopses which may take 9 ma ( cmc 4 ) or earthworks which take 10 , sorry not enough juse , never happened with any other I used
and 35 years is your experience , my is only 25 , but as it seems my is in the fields , yours in the studio

also its good you to know after 35 years that ni mh do not change drastically it voltage under heavy load ,in other words the battery which was 8,4 when it was fully charged will finish it life as 7v , still more then the alkaline . so what really matter is the capacity which 400 ma average in alkaline and about 250 in nimh .
Not sure where these numbers come from. First off the 8.4V is for the iPower 9V that you incorrectly say starts as 9V. virtually all other rechargeable 9V batteries start at 7.2 (there are some freak NiMH that start at a bit higher). The iPower (as stated in their spec sheet) start at 8.4 and end at 6.4. I'm guessing your talking mAH (since mA would be meaningless in this context). Alkaline 9V (under twice the load that iPower tested at) get about 300mAH. NiMH 9V are rated around 325 mAH.
--------------------------------------------------------------------------------------------------------------------------
my bad , i tough they are 3 cells , so they are 2 cells only ) 4.2 v maximum per cell , not change anything .
7.2 v is the minimum voltage for ni mh - 6 cells battery - each 1.2 v . maximum 1.3.1.4 so it charges for 8+++ and drops slowly
and here is no freak 8.4 , these are 7 cells batteries with lower capacity , what really matter is the total wattage of the battery ( v x ma )
know that alkaline usually rated for 400-450 ma for normal tests
-----------------------------------------------------------------------------------
325 ma for nimh -7.2 v - show me that , i will buy immidiatly
-----------------------------------------------------------------------------------------------------------------------------------------------------------------------------
BUT that is pretty misleading because as I think you were trying to say Alkaline batteries don't like big power draws and tend to discharge more linearly whereas NiMH batteries tend to stay close to the nominal voltage and then drop like rocks. So you get more usable life out of NiMH than an alkaline. Lithium batteries also act this way.
--------------------------------------------------------------------------
you don't have to repit what I said , , I see that you got it
If your trying to say that NiMH and lithium ion are better choices than Alkaline I don't think you will get much of an argument.
But my "35 years" doesn't have much to do with that. NiMH and Lithium ion batteries didn't exist (at least to the public) for most of that time. ;~)

who cares

but it good you to you to know after 35 years in that business that i power us batteries are lithium ion rechargeable which are 11.1 v with regulation to 9v and they have 500ma of capacity which make them much better choice and much cheaper for heavy load usage , not to mention cold weather where \are they outperform alkaline for 200 % of time running .
Not according to iPowers web site. 8.4V to 6.5V. Lithium also has a problem with heat. A number of devices specifically forbid using lithium batteries because of the possibility of heat damage. Also you are limited in the number/ size of lithium bateries that are allowed when traveling by plane. Since lithium bateries didn't exist in the consumer market when the FP33 was made one should probably check to see if there are any problems. Also the iPower 9V's are shorter than a normal 9V so that could also be an issue. Since your suggesting this use I assume you have used the FP33 with iPower batteries and have checked that heat isn't an issue.
------------------------------------------------------------------------------------------
tell I to 1000 of users who use power and millions of cellphone uses
number of batteries you can take have with total of lithium in grams inside battery - you can take 40 ipower instead 1 160 w camera battery - don't insult me with your luck of knowledge .
shorter , who care , it works

about my experience with sd mix pre - i have quit allot of experience with to make decision i don't like it , not for it sonic characteristics but as limiting device for normal work , at least for people who work eng films and not people like you who mostly take it to feed 2 channel of ambiance or make one mic interview .
Actually you have my experience a bit wrong. I do a LOT of FX recordings, also concerts and some run and gun ENG work. The MixPre has worked well for me in all of those situations. But I think you point is, and I agree, that the MixPre does what it does and if it fits your needs it is a good box. If you need a real mixer you won't be happy.

good , eventually you got it

I agree with some of the above. I have not found the MixPre power hungery. The "motorboating" thing is an issue IF you are trying to power a mic that needs 48V with the phantom power set to 12V. If you set the phantom switch to 48V it is not an issue.
-------------------------------------------------------------------------------------------------------
wrong - chocks on schoepces and eartworks , motorboating with sankens and akg s with 48 v

MS is not an issue for me because I hate MS recordings, but that is more of a personal taste thing so IF you need M/S that is an issue.
-------------------------------------------------------------------------------------------------------
you are not in eng /documentary business , probably you never been there for real
--------------------------------------------------------------------------------------------------------
I'm not sure what you mean by the pots and comfort, I don't find them uncomfortable but I would like to be able to make them harder to change and or lock them together. But that's because I do a lot of stereo recordings.
_________---------------------------
try other mixers , you will get it , start with wendt -
-------------------------------------------
Don't know exactly why one would output a mixer to a wireless transmitter but it would have been nice to drop to mic level once or twice.
---------------------------------------------------------------------------
stupid to carry another cable if you can do it in a moment with switch . I see you not relay in documentary as alwais
--------------------------------------------------------------------------------
Line in would also be nice at times but with only two channels it doesn't really come up much. this would be an issue if it were more of a mixer but since it is fundamentally a mic preamp if you have line levels to go to your recorder it's pretty simple to go direct to the recorder. I have a hard time coming up with a situation where someone would want to mix a line level with the mic in, and if your not mixing those signals then going direct to the recorder really shouldn't be an issue.

I would not call it "limiting" any more than I would call a shotgun mic limiting because you shouldn't use it to record in side. It's a tool designed to do certain kinds of work. If you use it for what it was designed for then it's great. If you try to use it for something it's not designed for it's a problem. Try to put an SSL in a bag over your shoulder and do Run and Gun. You would find it also "very limiting" ;~)
