No, you are mixing signals... (BD-Design)

Compare both pictures

The lower one (note the changed values) is were the filter is using the signal similar as going to the Fostex drivers (high gain). This is usually needed because the used filter principle is reducing gain a lot and AMP2 for the FW208N is "boosting" the lost in gain. With an attenuator you should adjust the gain for that amp.

You could also use a separate output of your pre-amplifier but then the filter should not be connected to the output of AMP1 at the same time as in your picture. The pre-amplifier should have its own dedicated buffer to "drive" that filter for the bass and you should be able to adjust the gain going to AMP1 seperately (reducing gain)

If both outputs of the pre-amplifier are simply connected in parallel then the filter is doing its things on both the main amps (crossing at 200Hz).

Ciao,

Bert
