I was setup with my smaart system this morning checking some speakers and wanted to check my 01v96 as well for filter slope on the lowcut and highcut. I had done this before but my pictures seem to have left for never/never land.
First picture is a reference set to 1000khz.
Next is low cut set to 1000hz. You'll see a 3db down point
Next is the measured 12dbs down at 500hz. Looks like the V's low cut filters are 12db per octave.
To use the 01v96 as a crossover taking 100hz and below out I first set the lowcut filter to 100hz. You'll see a 12db down point at 50hz.
Knowing that 2 - 12db filters give you 24dbs down I assigned the channel to a Bus and used that bus masters eq to add another 100hz low cut. (of course assigning the channel to st L/R )
In the pictures you can now see 6dbs down at 100hz 24dbs down at 50hz. 24dbs per octave.
Last I modeled at close aprox. to the filters with just 2 bands of the master eq section.
Low cut set to 200hz. Low-mid set to 112hz with a Q of 1.4 and a +6.5dbs of gain.
This gave a close aprox. of the 24db slope that running 2 100hz low cut filters in series did above.
Just wanted to put these up in case someone wondered what the filter slopes were in a 01v96 were and if they can be used as a 24db low cut filter.
I noted 2 80hz, 70hz 60hz etc low cut filters also yielded 24db slopes and the high cuts showed up as 2nd order or 12db cuts as well.
