Help with differences between BFD 1100/1124/PRO

Hey all,

I decided late last night to pick up a BFD off eBay and give it a go with my SVS SB12+. I was the lucky guy who had russ.will come round with his SMS-1 to help me set it up and I remember there being quite a big null in the mid-bass, so I thought I'd give it a go.

Unfortunately I put a bid on last night in a hurry and didn't quite think things through. Seems I've got the older model DSP1100 and not the PRO model at that. I've had a look but can't find any differences between the non-PRO and PRO models. I realise that the 1124 has 24-bit precision but is there anything else? Am I going to be ok with the DSP1100 or should I stick it straight back on eBay and get a DSP1124P?

Ta.

I believe the only difference is 24 bit processsors rather than 20 bit in the 1100,
lots of people happily use the 1100 as otherwise it is no different and I gather that for subwoofer taming the difference in processor makes little or no difference, without having any understanding of why I hasten to add :D

How did you get on with the 1100?
Thinking along the same lines and wondering whether to get an 1100P off ebay or a new 2496.
Quite happy to go second hand if it will do the job and work OK with REW.

Edit: Just read up on this on HT shack so can confirm that IronGiant is indeed totally correct :D

I was studying the 2496 specs quite closely as
a) it's the current model with a higher spec and is only about £95 new

b) the 1124 and 1100 are not for sale via retailers in Europe (as they do not have WEEE approvals), and frequently go for more than the 2496 on ebay

The only disadvantage I can see with the 2496 is that it doesn't have User Presets, so you cannot save various profiles, but it does have 20 PEQ filters/channel. I cannot determine from the manual whether it keeps its settings through a power-cycle though - any owners confirm this??

The 1100 has plenty of dynamic range - transparent for sub use.

"b) the 1124 and 1100 are not for sale via retailers in Europe (as they do not have WEEE approvals), and frequently go for more than the 2496 on ebay"
Or half the price if you have "luck". (Recent ones were £32 to £53, and I see 3 at the moment. )

"The only disadvantage I can see with the 2496 is that it doesn't have User Presets, so you cannot save various profiles, but it does have 20 PEQ filters/channel."

Presets can be very useful. I use 3. The number of filters could be an issue, but I think very very rarely.

The main thing is to get one of them!

I own an 1100P. Did they actually make a non-pro version? hmmm...

The bit depth affects the dynamic range of the system:
16bit - 96db
20bit - 120db
24bit - 144db
32bit - 192db

that, in combination with a bandwidth of 46khz would mean that your subwoofer would have to go from 0db to 120db (20bit) and say that meant an excursion of 25mm at 32hz then the BFD would give you an accuracy of 2hundredths of a millimeter... more than overkill. :D

Would I be right in assuming that as there is so little difference between the 1124 and the 1100 Pro that the REW & MIDI stuff would work OK with the older model?

Sorry, hadn't seen all these posts.

I got my BFD DSP1100 and have had some success with it. You can see my post about REW for an idea of how I got on.

Unfortunatly I didn't have a MIDI interface so had to set each filter the slow way. :thumbsdow

Yeah that 30 odd seconds can be a real killer :rolleyes: :D

Hey watch it! :lesson:

I spent a good 15 hours playing with this damn thing and at least a 3rd of the time was spent fiddling with knobs and buttons.

Ooh, doesn't sound bad when put like that. :D
