Along with your choice in crossover frequency, the PureBand™ Crossover System also provides you with four modes to
choose from:
Crossover Mode (CH1=LPF, CH2=HPF): When selected, this mode enables a LowPass Filter on Channel 1 and a
HighPass Filter on Channel 2 at the frequency that you have chosen.
Note: This mode will automatically put the input mode into "Input Y".
LowPass Mode (CH1=LPF, CH2 = LPF): When selected, this mode enables a LowPass Filter on both Channel 1
and Channel 2 at the frequency that you have chosen.
HighPass Mode (CH1 = HPF, CH2 = HPF): When selected, this mode enables a HighPass Filter on both Channel 1
and Channel 2 at the frequency that you have chosen.
Bridge Mode (either LPF or HPF): When bridge-mono mode is selected, the crossover system still allows you to
select a LowPass or HighPass fi lter at the frequency that you have chosen.
For instructions on setting up the different crossover system settings, please see the "Get Started" section at the beginning
of this manual.
