Xover
The crossover of the iAMP essentially enables you to
separate high and low frequency audio between the
two output channels, enabling you to better utilize the
amplifier's power for subwoofers or two-way speakers.
In addition to the crossover, there are also low pass and
high pass filters available on channels 1 and 2 respectively.
The low and high pass filters essentially allow you to select
a frequency at which signals will begin to be cut, whether
to remove noise and interference or simply improve the
overall efficiency of the amplifier.
The crossover frequency itself can be selected through
the "X-FQ" option. The crossover frequency is the point
at which the high and low frequencies will be separated
and sent to their respective outputs. The actual type of
crossover used is selected using the "Order" option. There
are 12dB/octave, 18dB/octave and 24dB/octave options
available. Each of these becomes gradually steeper, with
12dB/octave being a slight decline and the 24dB/octave
option being a much sharper decline.

Delay
Adding a delay to your outputs can be useful when using
multiple speakers over large areas. A delay time of one
millisecond per foot (or 3 milliseconds per meter) that the
speaker is away from the stage is the general rule of thumb
in this application (your mileage may vary). Thankfully the
iAMP DSP also offers distance settings to help take the
guess-work out of the setup.
Like most of the aforementioned functions, the delay
function offers a link and on/off options.
In addition to this, there are 3 different ways to adjust the
delay time of this function. You can choose to change the
delay in feet, meters or in milliseconds. For feet and meters,
the distance should be that between the speaker and the
stage. While any of these 3 options are adjusted, the other
2 will be adjusted automatically. This being the case, you
can adjust the delay in meters and then immediately go to
the mSec option to check the actual delay time.
FACTORY RESET
The iAMP can be returned to the factory settings by simply
holding the "SET/ENTER" button while turning the unit on.
During the start-up process the unit will be reset to the
factory settings.
