6.7 Bandpass2 72
Typical Use
To ensure a good signal/noise ratio and avoid distortion due to excessive loudness, the Audio Out
is often used in conjunction with a Volume and a Level.

Note: There must be an Audio Out in your patch if you want to hear you instrument. See also
Stereo Audio Out.
6.7 Bandpass2
The Bandpass2 module is a second-order band-pass filter (-6dB / octave). Its
one input is the signal to be filtered, and its one output is the filtered input signal.
Tuning the filter
The center freq knob tunes the center frequency of the filter to the desired level.
The resonance button is used to adjust the resonance of the filter around the center
frequency as shown in Figure 6. Note that as the resonance is increased, the am-
plitude of the filter response increases while the bandwidth of the filter decreases.
Typical Use
Bandpass2 filters can be used to make a parametric equalizer as in the patch of Figure 33. The
response of the resulting filter is shown in Figure 32.
The default value of the following parameters is set during construction
• Center Frequency: middle frequency of the passing band.
• Resonance: resonance around the center frequency.
