Digital room correction available now @ BD-Audio

[alphatoner]

ok still confused by this, reading up on tape loops. The monitor button (which I have but its not called a monitor button) when selected this plays whatever is going out through in my case taped rec/out. My confusion is that surely this is the signal going INTO the dpeaker ie before it gets processed. If the processed signal is returned to tape play/in, how will the monitor button help?

I don't mean to fill up this thread but just cant get my head round this at the moment. Don't see the point in wasting Jack's time with a demo if I can't even understand what to connect where.

The Accuphase E-305, according to the manual, has pre out/power in phono connectors on the rear.

Otherwise, if you hooked the device up as 'Tape 1' you would set your Input Selector to 'Tape 1' and use the Record Selector to switch inputs. Which looks a bit awkward, but would be sonically preferable.

Yes that's how you would use it.
Don't panic anyway Ian, I'm taking pre orders atm as all the units made to date are sold and we are waiting for them to finish manufacture of the next batch, probably next week before I see them.

[Dave Decadent]

Hello Dave D, would it be possible to use the tape loop and then run your tape deck in to a different input or do you record to tape fairly often?

Just checked the handbook; there's 'monitor' facility on 3 of the inputs so feasible. Now I just have to somehow justify the expenditure

Ok Jack i'll keep an eye on the thread

[bigdur]

No problem guys, just let me know if/when you're ready to order.

Credit/debit cards welcomed.

[bigdur]

Afternoon chaps, I just took delivery of 2 units, unfortunately it will be 2 weeks until any more are available due to holidays their end.

If you would like one of these 2 please don't hesitate to contact me.

BR
Jack

[bigdur]

Still available for free next day shipping.

Large stocks now in the UK, there are growing numbers of Antimode users all experiencing sonic bliss. If you have speaker/room issues drop me a line for a chat.

[Nick1881]

Hi, is there anyway to try one of these at home? I would only need the mono version for my SVS sub in my cinema setup.

I'm intrigued as to what it would do for me.

Thanks

[bigdur]

Hi Nick, been out for the day so sorry I missed your post. Mr Hifiwigwam any idea why the email system is playing up? I don't seem to get notifications on some of my threads any more?
Anyway, I'll drop you a PM to discuss Nick.
Cheers,
Jack

Hello Jack,

Would one of these magic boxes work when the room isn't quite big enough, say going from a 13x12 foot room to a 9x8 foot room. Or have i got the wrong idea about the magic in your boxes.

[bigdur]

Yes Lee, if your speakers are too large for the room and driving large bass peaks etc it will cure this. It will also allow you to move your speakers closer to corners and rear walls which causes bass boom issues normally as it will process and cure the problems.

[purplepleaser]

oh thanks for the info Jack, might need to call and get a try when I move to a new house, smaller music room looms in my future.

[bigdur]

See how you get on, if you feel you have an issue give me a bell, happy to help and it will fix any problems, if not I recommend spending the cash on beer and curry.

[purplepleaser]

ta, this might make the bungalow choices easier on me for room size and stuff.

Sent a screenshot from another customer today.

Hi Jack - firstly, the plots you've shown suggest only cuts in the output, not lifts, is that right? ie, in an extreme case why is there no boost shown here to the sub-50 response?

Secondly - as I ponder the direction of my set-up I'm seriously considering one of these depending on which speakers I get left with.
The use of your labs has sadly been truly overruled by my good lady when I measured up and showed her where they would go, one of them would obscure most of the front window

So it's back to the drawing board - now the LVs are pretty tight and fast down to say 35Hz, but feck all below that, which I miss, I spoke to BK about their XXLS400 which is flat to 20hz in room but the lowest low pass roll off is 40hz so a big crossover bump right where my room complains - they would specially mod a pair for me to extend the roll off freq to 30Hz so that I can integrate them better, but that then leaves me pondering this little device as a cool integration tool.

I am running a SBT via coax into an audiolab MDAC, into a Consonance pre, into Consonance monos. I want to use TWO subs, fed by a stereo signal, ideally to create a flat20 in room. I'm concerned about the point in having a highly regarded DAC in the chain if the antimode is feckin about with the digital signal before the dac even gets to see it. If I understand it right, even placing the antimode in the analgue chain results in a further ADC/DAC loop, right? So by default, you MUST use the onboard DAC from the antimode somewhere in the chain, it's a digital device? So that then becomes the lowest denominator in the system? therefore NO point have a second 'better' DAC further up the chain as it's only got the output from the Antimode's DAC to work with right?

That said, it may well be that the effect of this device far outweighs the differences in DACs...
Given my system above, do I need the specially altered subs?
Would the antimode drive a flat response working out the issues between speaker/subs/room?
The changes are presumably valid only at one listening position as bass response and modes will be completely different depending on where you sit up and down the room?
I'm guessing SBT > anti mode dual core (must be true stereo?)>MDAC (any point..?)>pre>power is the best route?

Sorry for all the questions!
cheers
Steve

[Parkandbike]

As far as I understand the anti-mode does not attempt to boost dips, but some may be reduced when the room modes are tamed.

You can set it up for an average of three listening positions if you wish. I'm selfish and have it set up for my listening position only.

Will you be using a line level-signal or a speaker level signal to fed the subs (that is if they have thier own amps) ? I'm using the antimode to feed a line-level signal to the subs in "your" Duos, that way it cannot impact the critical in the critical mid range (I'm not saying it would, just that I wanted to avoid the possibility)

[steve rb]

I *could* take a split output from the pre and feed one into the antimode then out to the line levels of the subs, but that brings all kid of gain issues with it and still then wont touch the bass in the LVs. I guess therefore it has to go via the high level input and the antimode covers all...
Seems strange that it only works in one direction. That would leave me cranking the subs right up to get the lower end where I want it and letting the antimode hammer away at the resulting huge peaks around 30-40hz, but that means pulling the LVs right down with it...not ideal.

[bigdur]

Hi Steve, I'll type a a detailed post later on today/this evening, unfortunately we're due at a funeral 2pm.
If you run between the Squeezebox and Mdac you run in the digital domain so the Antimodes DAC is unused. The graphs I've been posting are the initial auto correct ones, dropping only peaks though it is possible to manually adjust the EQ wherever needed......
