attenuator cable = minimize bass?

[dajmno]

I just purchased the core sound attenuator cable (20db).

I've been getting some good recordings using:

Core Sound Binuals > Batter Box > RH10

I don't believe the bass roll off (it's the switchable battbox that is sold on core sound) on the battery box works with the RH10, so I simply use it as a power source, and run the microphones to the "line in" on the RH10.

My recordings, like I mentioned before, do sound pretty good, but it wouldn't hurt to get a recording with a tad less bass.

I know the attenuator cable brings the "signal" down, but does it in the process also reduce the bass? Once, I receive my attenuator cable, I'm planning on taping my next show with the csbs and attenuator cable, via "mic in" without the battery box, and see what kind of capture I get.

Also, is csbs > batt. box> attenuator cable > "line in" a viable option?

Thanks

oh, and you can hear samples of my recordings on http://www.dajmno.com

Without external power supply / battery module, the attenuator reduces the already small enough bias voltage (plug in power) from the recorder's mic-in and thus the mic's dynamic range. High SPL handling abilities will be reduced, S/N decreases. All frequencies get equally attenuated, there's no roll-off effect. You're better off to continue using battery module -> line-in without any attenuation - the line input requires no further attenuation. The low frequency amount can be corrected precisely via software afterwards instead of having to use a fixed 6dB/oct filter/roll-off.

good info

thanks!

I didn't know you can separate the csbs from the battery box. Can you?

[dajmno]

you can, there is a mini xlr plug that is in the middle of the cord that goes hooked up to the batt. box, then at the end of the mic cord the regular mini 1/8 stereo plug.

I imagine, they would still work even though the mini xlr plug isn't hooked up, not sure however.

my setup:

i just did a quick trial, in which I EQed the bass down on one of the tracks to my recording via soundforge, sounds good!

In any case, be sure to keep a copy of the unedited original file. You might change your mind about post processing later.

Where do you place the mics when recording?

[dajmno]

usually just clip them to the collar of my jacket (chest-high), sometimes will clip them on my eyeglasses.

I do a lot of recording on shirt-collar tabs, shoulder-high. Chest-high might muffle highs and bring out bass. Do you hear any difference when they're up on your eyeglasses?

[dajmno]

little difference, when I'm up on the eyeglasses the sound tends to be clear and crisper, I'd say the amount of bass is the same, maybe a tad less. I prefer the sound that I get when I have them on my eyeglasses, but can't always use that option.
