for those interested, I confirm that the filters in the EQ section are 12dB and that the response received and posted by "mbbx5aw2" is correct, except for the difference between the two EQ section filter types.
Please read the details below:
Type II reacts to Q-factor and can be adjusted to a very high resonance, Type I reacts to Gain, with a rather subtle resonance. That is for compatibilty reasons. Type II was introduced with StudioEQ. Type I is the old Channel-EQ.
For small values of resonance they can be set to be (almost) identical, for example:
Type I Highpass: Gain 0 dB, 1 kHz, Q 1
Type II Highpass: Gain 0 dB, 1 kHz, Q 4.1
Hope this helps.
