3. Bracketing Filter Operation ED A Bracketing Filter has been incorporated in to the TourBuss suite providing Low and High 12dB per octave filters that attenuate any unwanted frequencies Thus making it simple to remove unwanted frequencies without using the resources that a more complicated equaliser would utilise The most widely used function of a bracketing filter is to remove signals created at high or low frequencies that bleed into the source and can be used for tuning into an acoustic guitar for instance to remove background rumble etc Meter A meter above the key filter controls provides a visual representation of the LF and HF controls showing the full key filter range from 31 2Hz to 22 6kHz As the LF and HF knobs move so do the corresponding pointers on the meter Note that as one filter gets within one octave of the other it also pushes that control The pointers can also be moved by the mouse E H F Cutoff frequency Cutoff frequency Amplitude Frequency Set up correctly and you will have removed all the room vehicle rumble high frequency amplifier hiss etc that any mic may pick up On a snare drum this filter can be very effective in controlling bass drum leak or on a bass drum removing snare rattle Acoustic guitar or backing vocals can be greatly improved allowing you to hear midrange clarity and stereo separation without the need for any additional equalization gt O S O A A o E a S T
