When a Pro Tools system is operated at 44.1KHz or 48KHz sampling rates, the highest signal
frequency is limited to around 20KHz. However when centre frequencies above 20KHz are
selected, the EQ maintains a response that is accurate for any portion of the curve that lies
within the legal bandwidth limit of the system.
