Topic: SP-SPSB-11 roll off setting help

[yawnfactory]

i usually get a good amount of bass, but it seems the "wrong" settings killed the mid tone of the guitar for certain bands (nebula, as an example)
so here we go trying it the right way today, with no roll off. will see what happens. hopefully i get there early and can test
it out on one of the openers.
i did email sound pros about the frequencies, but didnt get an answer. perhaps they too are waiting for an answer.

You'll save yourself a lot of aggravation by permanently forgetting the roll off and learning how to do it in post (if necessary).

sorry to get this old one high, but i am pretty unsure.

is this set up right for 69 khz bass roll off (1, 4)?



thanks so much for any help!

QFT.

I never use roll-off anymore just in case what I'm hearing versus what the mics are hearing differ (which is quite often different).  It's easier to do this in post after the fact as fmadejr said.   Somebody on here once told me that it's easier to roll off unwanted bass after the fact but you can never add it back in to a tinny-sounding (lacking bass) capture.   Hope this helps.

Yes, according to the seller, but it will only be true if your recorder's input impedance is 10 Ohms. If your are going mic in to an R-09 for example (20 Ohm impedance) your roll off will only be 69 x (10/20). Just another reason many off us don't use a battery box with a roll off.

Your desired Roll-off Frequency
These switches set to the “open” position (assuming 10 Ohm recorder input impedance):
16Hz (no roll-off) 2,3,4
69Hz 1,4
95Hz 1,3
107Hz 1,3,4
160Hz 1,2
195Hz 1,2,4
888Hz 1,2,3

1st What a great place 

A few questions on this subject.
1) on these battery boxes which is better to get the hardwired output cable or the removeable output cable and why?
2) after reading this discussion is it better to get the sp-spsb-10 w/o the roll off then the sp-spsb-11 w/ roll off
3) if i get the box w/o roll of what software are you using in post. production
my setup would be
sp-cmc--2 > battery box > sony pcm-m10
any other input would be great.
thanks in advance
happy jack

Resurrecting an old thread to save me posting the same stuff again.

@fmaderjr You mention the 20 ohm impedance of the R09 which I also use, so if I set the roll off to 69khz what roll off am I actually getting?

Is it better to go with no roll off and set it to 16khz?

The mics I use are either SP-CMC-4U cards or CA-11 omnis.

I'd suggest getting the removable cable because if that cable breaks you can replace it. If a hard-wired cable gets loose or staticky, there goes the battery box. Of course, you do need a reliable cable and you have to make sure it's plugged in.

Don't spend the extra $$ on bass roll-off. Bass roll-off used to be helpful--maybe, possibly, though I never saw the point--on recorders like minidisc units that would distort with big bass. But  recorders now can handle the whole spectrum better (assuming you have levels set sanely) and bass roll-off on the battery box is crude at best. Better to get the best fidelity your mics can provide and tweak later (if necessary, probably not) than to get a recording you can't restore. It's like a photo--you apply the Instagram effect after you shoot the photo, not while shooting it.

As has been repeated here, you can do any bass roll-off with software--even software as basic as Audacity, which is free, has lots of equalization options. You can also do it with the EQ in whatever you are using to play back the music.
