Hey speakerplaners :) hope everyone's well !
I'm gonna be using two different dsp units for a gig ! I need to find out the inherent delay caused by the AD and DA conversion in the dbx driverack pa + and also the Behringer dcx 2496?? So I can accommodate into the delay settings for the rig ! If anyone knows , let me know :) cheers |

unless you need 12 outs just daisy chain one unit into the other and you still have 10 outs and no problem with different delays

Hey mate , yeah that won't work as you will still have an extra bit of latency from the second dsp , only on the outs on the second dsp !!

Measure it with rew or other software

+1 or you could use the dcx's built in delay finder function...... with a little hack..... |

I meant use the first unit for the tops, use two outs to connect to the other and use the six outs on that to run kicks and subs. or vice versa. left and right will be identical. any latency gets accounted for by auto-delay function.

Which rig are you doing with this?
Using one dsp for subs only is ok because the group delay of the subs will surely be lot bigger then the dsp latency.

Thanks for your help guys ...
I have a wide spaced stereo stack using jbl 4675 c 4lf cabs ... Then I'll be using two jbl 4675 d 4lf as a mono infill !! Stereo stack will be sitting on two Meyer twin 18" reflex subs each side ... Then mono centre infill will be sitting on one twin 18" reflex ! System will be run from 3 labgruppen 10,000 q amps ! The dcx will be picking up master outs from the mixer ! Output 1 for subs / output 2 (mono sum ) sent to the driverack , split into both inputs / Output 3/4 , jbl 4675c mids/ output 5/6 jbl 4675 c comps ! Then the driverack will be the mono proccessing for the biampd jbl 4675d mono infills ! It was actually quite handy feeding the dbx from the dcx as the dbx won't mono it's inputs so that solved that ! Also it allowed me more bands of parametric eq on the 4675d cabs , that the dbx doesn't support ! Only difference between the 4675d and the 4675c is the horn on the comp! In reality it means you need different delay settings and slightly different eq ! Crossover has been carefully selected to work for both ! Iv come to the conclusion that the extra delay in the 4675d cabs that are running through two dsp rather than one is relatively negligible.... Being the mono infill they will want to be delayed some to the stereo stack anyway ! |
