The OA4200.4PRO 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 setting to the desired HPF

setting 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 setting to 50 Hz and the LPF Frequency

setting to the desired Low Pass setting to block out unwanted high frequencies.

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.

THESE SETTING CAN BE USE ON CHANNELS 1-2 OR 3-4

INDEPENDENTLY OR FOR ALL CHANNELS
