analog and back again. To use the S/PDIF
inputs, the Input Select switch must be set
to allow the iA equalizer to accept the signal.
The output sampling rate is selected using the
Output Select switch. This feature is available
on the iA231FD only.
15. Sampling Rate Switch (iA231FD only)

crossover frequency can be selected between
15 to 250 Hz by the small control located next
to the output.
19. Analog Inputs and Outputs
The female XLR inputs are for the addition of
external analog signals to the iA equalizers,
whereas the 3-pin XLR outputs are for the
connection of external devices to receive the
equalized signal. There are also input and
output operating level switches, which allow
users to adjust the iA equalizer to suit either
pro and semi-pro audio equipment, as well as
consumer level audio products. Set at +4 dBu
for professional audio products, and -10 dBV for
consumer products.
