Ashly for 4343?

[pyonc]

Hi, friends,

Please enlighten this novice audiophile on XOVER and its relevance to woofer.
The other day I obtained Ashy XR1001 for biamping 4343.
As you might know, the built-in frequence range for this 4343 LOW is 300Hz,
but this Ashly has 400Hz as the starting point. :blink:
So, does this higher XOVER point (400Hz) have any effect on 4343's 300hz woofer,
more or less bass sound? If so, what's the best solution?
I have a Behringer XOVER (kindly loaned by our mutual friend Paul), and JBL M552, for both XOVERs,
I can control the frequency button close to 300Hz, fortunately. I know the best thing is to trust your ear, but I still want to know any relevance out there. Any idea? Thanks a lot for your input and suggestion in advance.

I don't have one, but I happen to have a manual downloaded because I was looking at acquiring one.

There is a divide by 10 switch on the unit (the LED is let when active). Which changes the crossover range frombetween 40 to 800 and between 400 to 8000 hz.

You can download the manual from the web if you don't have one.

Let us know how it works, because I thought this might be an OK way to go.

Flip the switch and go from there!

Works fine with my 4341 system - got the button on the Ashly set in the divide by 10 range and set on (approx) 290cps errrr Hz ... does the job.

As you know, I use this Ashly in a 2-way stereo, where the crossover point starts 400Hz.
But if I want to do as you suggest, I have to push the mono 3-way button. Is this what you mean?

Thanks for the suggestion. In that case I have to push the mono 3-way button to switch to the frequency range between 40 and 800. Right?

[brett_s]

The divide by 10 dip switch and the 2way/3way button are independent from each other.

Leave it in 2way, find the divide by 10 dip switch, and all should be fine.

Again, I don't have one, only the manual. So take what I say with a grain of salt.:eek:

It should work fine. The "recessed Range switch" requires you to push it in with a small probe. The button you're pushing is recessed behind the hole where indicated. The lights will indicate whether you're on the inner ("normal") band on the Crossover Frequency knob (400Hz to 8kHz, green light) or the outer (÷10, 40Hz to 800Hz, yellow light).

Works great on my 4345s.

This applies to my XR1001. If you have the later XR-1001 (possibly made in China), I can't be sure that's how yours works though the manuals make it appear the same with the word "Crossover" missing from the knob label on the later version. ;)

Sorry for the blur - the flash made it worse, and its not well lit in that corner of the room at night. Best I could do on short notice.
Anyway - Ashly XR1001 - note the recessed hole with the push button inside for "RANGE" - note the RANGE light is on when its in divide by 10 mode ...

Each of the 2 channels has this setup

Go forth and do likewise

Press the RANGE switch so that the yellow LED lights up which will indicate that you are the 40-800Hz range. Dial the CROSSOVER dial to somewhere between the markings 2K and 4K (which is now 200 - 400 Hz) and all should be fine.

Thanks so much! I just did so, and the RANGE light is on.:applaud:
Now I think I have to try Ashly afresh, and feel the difference.

Thanks a lot. You're super!:applaud: I pushed the inside button (RANGE swtich), and the green light is on. I reset the XOVER dial between 2K and 4K, as you suggested. I'm going to try this newly set Ashly for any difference from other XOVER brands like JBL M552.

Bravo! Thanks for your nice explanation. Novice like me couldn't notice something like RANGE switch inside the hole. By the way, I've just confirmed it's made in USA, with production identificatin Q2-02. :)

If the GREEN light is lit, you've set it to 3,000Hz (3kHz), not 300Hz! Push the button again until the YELLOW light comes on. Here's my setup:

Ooops! Thanks so much for correcting me! I just did so.:applaud:

[BMWCCA]

Ooops! Thanks so much for correcting me! I just did so.:applaud:So how did it sound the other way? Like a 4333 with a bad horn? :eek:

[pyonc]

So how did it sound the other way? Like a 4333 with a bad horn? :eek:

Yes, the sound is louder and clearer.:D
With JBL M552, I think I get a little louder sound, compared with Ashly, though.
I'm not sure which is the better one at this point, though Ashly produces a sharper and more even sound on both speakers to my ears.

That shouldn't make any difference if you have enough gain to make them both the same level. Assuming you're set at unity gain on the Ashly, just turn up the volume control on your pre-amp!

Got it! By the way, do you have any reason why you set Response volume at 6db in your Ashly? Is it the normal setting?

[hjames]

Its not "Response Volume" - its setting how the low pass and high pass filters interact. How sharp the slopes/cutoff where they cross.

Got mine set at 6db slope as well ... (see blurry pix)

Let me set the same like you. Thanks!

The Ashly manual linked to in this thread is very helpful and descriptive:


5.4 Response
This control, found adjacent to the crossover fre-
quency control, adjusts the damping of the filter affecting
the response shape of the filters at the crossover point (see
drawing). The dial calibrations refer to the amount of at-
tenuation effected by the filter at the crossover frequency,
i.e., a setting of 3dB means that the filter’s high-pass and
low-pass outputs are each “rolled off 3dB at the crossover
point”. This describes Butterworth filter response, or a
gentle 3dB peak at the crossover point when the two filter
output signals overlap. To obtain a flat signal, or
“Linkowitz-Riley” response through the crossover region,
set the Response control to “6”. This attenuates each out-
put of the filter by 6dB at the crossover point (two identi-
cal signals added together yield a +6dB increase). To ob-
tain a notch at the crossover point, turn down the response
control past “6” to best suit your needs.
at unity and controlling system levels either prior to the
crossover or at the output level controls.

Sorry, I don't want to hijack this thread, but I have a question on connecting the Ashly XR1001 and I thought someone on this thread would know.

If your processor as well as your amps have RCA connectors, what is the preferred way to connect to the XR1001?
A. Use a RCA to 1/4" TRS unbalanced connector (Tip and sleeve). adapter cable
B. Use a RCA to 1/4" TRS balanced connector (Tip,Ring, and Sleeve) adapter cable.
C. Use a RCA to XR connector adapter cable.

My first thought is that it is A, because everything would be unbalanced then. However, there is a note in the manual that I don't quite understand. It says:
" If you must use unbalanced connectors, the negative lead of the connector should be tied to the ground lead. Using unbalanced connections could result in chasis ground-loop noise. Alternating the signal/chasis ground relationship in equipment connected to your MQX unit may eliminate the noise." :dont-know:

Can some explain this to me and advise on the preferred hookup method if the processor and amps are RCA connectors.
Thanks,
Brett

[brett_s]

Pyonc,

Do you have any more update on this setup after a bit more listening and adjusting? I'm curious to your thoughts. Are you happy with it?

Also, if anyone has the answer to my hookup question, it would be appreciated.

Brett

Also, if anyone has the answer to my hookup question, it would be appreciated.

I'm essentially using your option A, though I was able to pick up some very nice cables terminated at one end in RCA and the other in 1/4" plugs for pre-amp-to-Ashly—and my amps have 1/4" jacks so that was a no-brainer. :dont-know:

Hi, all,

Thanks for all your great input and kind responses.
For the past couple of weeks, I've A/B'd JBL 552 and Ashly XR1001, with the setting of various gain controls marked at their closest levels. Outcome? With 4343s, I hear crisper, louder and more real live-like from JBL M552, contrary to the dominent opinion in this forum that Ashly beats M552. The CDs and LPs I played to check them were all jazz music. Maybe it all depends on personal preferences, but as of now, I want to give higher marks to M552. Just my little thought on this thread...

I'm not sure it's that black-and-white. I think Scotty did a very nice job discussing the good and bad of the M552 here: http://www.audioheritage.org/vbulletin/showthread.php?20168-Jbl-M552-vs-JBL-UREI-525-crossover&p=203401&viewfull=1#post203401

Absolutely agree with you! It's just my personal taste.
I think I have to try Urei 525 as it has 18db/octave crossover.
Thanks for the info on Scotty's thread.
