Wanted to know what the recommended crossover setting to use for a dbx PA+ to use for a nightclub. Running a pair of JBL PRX415M with a Crown XTi 4002 amp and one JBL JRX218S Sub with a Crown Xs500 amp.

    That single sub will have a hard time keeping up with the 2 tops, so a lower than normal x-over point should be used to allow the sub to focus output on a smaller band.

    Sub:
    50hz BW18 - 80hz LR

    Tops:
    80hz LR

    You can play with the 80hz to find what works best.

    Hi Dra, you've mention to set the Sub at 50hz BW18 - 80hz LR. What is the setting for LR? Is this setting suppose to be set at 24? Also I notice there is two setting for the low. The second page shows a gain db. Is this where 80hz LR setting should be set or should this be 50hz BW18? Thanks again for your help.

    Sorry. Yes, the LR should be LR24.
    Yes, 2 settings for the lows. A HI-PASS filter (low cut) of 50hz, and a LOW-PASS filter (high cut) of 80hz.
