Title: Soundprofessionals SPSB8 bass roll-off
Post by: dkarDaGobert on December 02, 2006, 03:38:35 PM

I´ve a question to the soundprof spsb8 owners!

I looked at the Soundprofessionals manual page, and don't see a manual for the SPSB-8 battery box.

http://www.soundprofessionals.com/cgi-bin/gold/category/manuals

But the other SPSB manuals all show the following settings:

desired Roll-off Frequency    These switches set to the “open” position
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

I hope this is helpful.

On my battery box, the numbers 1, 2, 3, and 4 are at the top.  Below the white control switches, it says "open." 

So, if I wanted to use 16 khz rolloff, it would be your picture # 1 (your picture is blurry, so I am assuming that the 1, 2, 3, and 4 are at the top of the picture).

in your pic it looks like you have them reversed too
#1 it looks like is set at 16 #2 is set the in reverse
#1 has 2, 3, 4 open
#2 has 1 open
or so it appears to me

yes I THINK #1 is set at 16
if yours is built like mine AND the info above is correct to the box THEN yes #1 is set to 16

I wonder what would happen if you use the reverse of the 16 Hz roll off. A treble roll off ?
