BUILT-IN CROSSOVER
The

and
OA4800.4PRO
amplifier allow you to select the crossover
mode (High-Pass, Full Range or Low Pass / Band Pass) and desired crossover
point for channels 1-2 and 3-4.
For example if you wish to use a 2-way loud speaker on channels 1-2, simply set
the crossover switch to HPF and adjust the frequency se

se
tti
ng to block out any unwated low frequencies.
If you wish to run a subwoofer on channels 3-4, simply set the crossover switch to
LP/BP.You must adjust the HPF Frequency se
tti
ng to 50 Hz and the LPF Frequency
se
tti

If you wish to run a component midrange on either channels 1-2 or 3-4 set the
crossover switch to LP/BP. Then use both HPF and LPF frequency controls to
create the desired band pass frequency range.
