Setting up xovers and phase alignment.

In this coming weekend, i will try to set up xovers, phase alignment and delay on my system.

BUT, what if i use some other amps with the same DSP and speakers. Will the phasealignment be different, or does the choice of amps not affect the setups alignment?

I would like to make a preset on the DSP that fits my speakers, and not be forced to use the same amps every time (dry hire friendly).

I only use old school HEAVY amps like RAM Audio BUX series, Crown Macrotech series and Crest Pro (the old HEAVYYYY series!)

I will make some DSP settings then :) 

 

SMAART is not the only 1 that has problems finding delay time on low frequencies . That's where the phase display comes in to play .

Set the system as it is right now all on (full range) . Synchronise smaart with auto small/large . Than start alligning each speaker @ the x-over frequency using the phase display .

Getting the delay on each speaker individualy using auto small/large will give you problems because it's band limmited pink noize specially on the subs/ lower frequencies because of the wave lenght / period . It has problems finding the peak .

First i want to do a few articles about cardioide sub array's but after that i'll be writting about a allignment with a line array system where i'll be trying to use as little delay as possible and a lot of phase filters (all pass 1 and 2) . that might take me a while because technical english is rather hard for me but it will be there in the near future .

 

 

There is no problem doing this. I use different combinations of bass and mid/top cabinets as well as just using the mid/tops full range. All the different combinations are saved as different presets. I just select the preset for the required amp/ speaker combination.
