ADAU1701 minimum signal processing delay

I have a question:

I would like to use the ADAU1701 for a simple multiband equalizer processing of a stereo signal. I need 2 different equalizers for the signals, and I need 2 analog inputs, and 2 analog outputs. I would like to know how much is the delay from when the signal is received on the input pin, and when this signal is processed and putted out on the analog out pin. I think it depends on the sampling frequency, and Pll settings, but also on the ADCs/DACs conversion times... How can I calculate it, and also reduce it, if possible?
