central station: phasing(?) when using both monitor A + C at the same time

central station: phasing(?) when using both monitor A + C at the same time

just hooked up my central station last night.... it seems to run OK... but, when i engage both monitor A and monitor C outputs at the same time, i get some sort of weird, phasey mix .... most definitely not a clean signal from both sets of monitors..

basically, using 2 sets of monitors at the SAME TIME is not possible.. as the quality of that phasey screwed up signal isn't worth listening to.

anyone else experience this?

i bought the CS second hand.. so i'm not sure if it has a problem or not.

thanks

Sounds normal to me. You're hearing the phasing due to the acoustic phasing of the two sets of speakers. It's not a flaw in the CS, it's just physics. Why would you try to listen to both sets of speakers at the same time?

yeah, i won't use both sets at the same time ... good point, however, my Big Knob did NOT have this "problem"... although now i'm remembering its because i was listening to a THIRD set of speakers that was not near the other ones, so there was no phasing really...

if what you say is true (which it sounds logical to me)....

becuase right now, monitor A (adam A7) are sitting on top of a crappy pair of KRK. (monitor C).. when i play A+C at the same time, i hear the phasing.. and that's maybe because the monitors are right on top of each other, so the signals are coming at me from almost the exact same location.

i need to hook up monitor B (genelec 1030) which are in a different location in the room... and see if i get phasing when playing B + C... which maybe i won't, becuase they're in 2 different room locations.

sound right?

but, ultimately, yeah, i won't be using them at the same time.. i just wanted to know if it was a defect from my 2nd hand unit, which arrived in pretty bad shape! (i had to open it up and reattach the VU meters.. and someone had sawed off the rack ears!!!!)

The "C" output is meant for a subwoofer.

This is the second thread today starting out asking if a Central Station was defective, and it turns out it is something else.

well, according to the manual, the C *could* be for a subwoofer, but doesn't have to be...


i have 3 sets of monitors.. i should dump one anyway!

adam A7, 1030A, some $300 pair of KRK.....
