Chapter 6 Component Guide Programmable LPF The low pass filter passes frequencies in the signal that are lower than the specified frequency, while attenuating higher frequencies in the signal. With the programmable low pass filter you can set the filter type and the slope between the frequency band that is passed and the band that is cutoff. There are two types of programmable LPF components: mono channel and stereo channel. Mono channel programmable LPFs have one input and one output. Stereo channel programmable LPFs have two of each. Double-click a component to display the component editor for it. The parameters are the same for mono channel and stereo channel components.

Reverses the phase of the input signal. Sets the LPF cutoff frequency. Sets the attenuation for each octave and the filter type. [THRU] turns off the filter. When [AdjustGc] (Adjustable Gc) is selected for [Type], this sets the gain for the cutoff frequency. Turns bypass ON. Sets the output signal level. DME Designer Owner's Manual 427
