mdfan Posted March 9, 2004 Report Share Posted March 9, 2004 Im going to try to build my first set of binaurals and battery box, using the diy info on micdiyers website. I have not seen anyone mention how to add a bass roll off for the diy setups. Any advice? Quote Link to comment Share on other sites More sharing options...
Leland Posted March 13, 2004 Report Share Posted March 13, 2004 I think the bass rolloff is determined by the value of the resistors you use for your box. search around for something like that on the web. Quote Link to comment Share on other sites More sharing options...

I have not seen anyone mention how to add a bass roll off for the diy setups. Any advice?You should choose the capacitor (not resistor!) value according to the roll-off frequency you desire. I saved a mesage from the micdiyers list: --- In MicDIYers@yahoogroups.com, joef@a... wrote: >I know I've posted the formula with worked out examples before ... >it ought to be in the archives if you can formulate a search from >the MicDIYer's yahoo page. Here's some pre-calculated values for those of you who are in a big hurry. These just happen to be the capacitor values used in the Sound Professionals battery box, with the rolloff points calculated for the two commonly specified input impedances. For 4.7K Ohms Mic Input: 1.02 uF= 33 Hz .234 uF= 144 Hz .171 uF= 198 Hz .153 uF= 221 Hz .1 uF= 338 Hz .081 uF= 418 Hz .018 uF= 1881 Hz For 47K Ohms Line Input: 1.02 uF= 3 Hz .234 uF= 14 Hz .171 uF= 19 Hz .153 uF= 22 Hz .1 uF= 33 Hz .081 uF= 41 Hz .018 uF= 188 Hz --- End forwarded message --- Hope this helps.
