Hi ... Thanks to the forum's help I now own an Ashly 4001 crossover.
The first thing I noticed was that each channel is controlled separately.
Is there a way to accurately balance right and left speakers without creating crosstalk? Thought a LED circuit could be wired into each speaker pair to null. Zene
Follow Ups:
If you dont have a device to give you a pink noise signal then
try getting a test CD from www.stereophile.com that has a pink
noise track on it and other test signalsJust set repeat on the track on your cd player for continual output
If you dont have a decibal meter then you can go to Radio Shack
and purchase a digital DB meter, or find one online.The scrap shack one will work for what your doing and is affordable
Simply run pink noise and set your levels accordingly
You can do it through each loudspeaker and compression driver
on each side to match levels or however you want to do it
You can throw the db meter up on a tripod from a central location
to set output or you can place the meter in a close proximity to
each loudspeaker or driver to get output.
As an example...1meter (3.3ft) and in the same position in
front of each driver you are comparing
Stuart ... Thx, but if you read my second post you will see that I have all that equipment as well as TrueRTA and know well how to set levels. Not everyone here, asking questions is a rank amateur.
But each time I just touch a crossover knob or a volume knob it upsets the balance. I need to quickly input a tone and reset the left and right levels with some kind of a null meter. Takes about 15 sec to run over to computer and input frequency. There is no other way to do it fast. A switch back to cd and I'm listening. Rem: the Ashly is not a stereo x'over, it's dual mono.
Thought someone in Pro would have the technical ability to come up with a quick circuit that would work, or direct me to someone? It would be as simple as a center zero or digital AC meter with the right circuit. As I said, it would be in system permanently. Hope I clarified better? My forte is babbling with my hands flailing, not typing. Zene
Do you have a generator and a SPL meter? There is an accurate method to set your crossover with those tools. Without a SPL meter, it is still possible to set your system, although it's trickier.Which is your case?BTW crosstalk is not something you have to worry in this case.
However, first you should set the crossover frequency to the same value on both channels.
Not doing that (and /or not using the same kinds of speaker boxes on each channel, in this matter) would likely jeopardize some of your stereo imaging, but it is in no way crosstalk.
Jacques .. Thx, but you really need to READ my most recent post. SPL meter and generator went out with high button shoes for my needs. I know I'm asking for a lot, but that's why I'm here. I know it's doable but I'm not an ET.
Thanks, Zene
Jacques ... Thx. Yes, I can always set them manually, but I want something ongoing. My system is a changing lab. Not a set and forget. It is quad amped and soon to be oct-amped, one amp per speaker. I experiment with the setup and speakers frequently.
The only individual volume controls are in the crossover and they are not linked, no volume controls on the amps.
The only master stereo volume controls are on the preamp and soundcard. Hope I've explained better. Above is why I need an electronic null device.
The other reason for needing one is to have an electronic equivilant centre detent. Fine tuning means that one speaker might be set to a different level depending on room acoustics so I can get back to zero quickly. Perhaps someone can suggest an electronic forum that deals better with these kinds of problems. Zene
