The EQ controls are shown opposite. Avid has a well-earned reputation for the highest quality EQ algorithms with an uncompromised approach to design. System 5’s equalizer is much more than just a simple EQ. The four bands are each fully parametric, with additionally switchable peak/shelf selection on two of the bands. Frequencies are not limited to fixed ranges; each band covers the entire 20Hz - 20kHz spectrum, with a gain +/- 24dB and local variable Q control.
The Page key at the bottom of the knobs brings up the Filters. There are two Filters that can each be set to: High Pass, Low Pass, Band Pass or Notch. Each filter has a frequency control. The notch filter includes Q control and a “boost/listen” function, monitoring the audio without the filter in the circuit, to help identify any problematic frequency prior to selection. A 50/60 Hz hum, or other unexpected noise problem can be taken care of without disturbing the program mix or compromising any equalizer settings as with shared designs.
Whenever an equalizer is being adjusted a graphical display appears to illustrate what the processor is doing to the audio at the top of the channel.
