New Belton BTDR-ABE Reverb Brick?

[frequencycentral]

@frequencycentral  ,, out of interest what price were they selling at ?

23.80 EUR

[Mr. Lime]

It was like 23€..

- Anyone know what that third IC is? The 16-pin QFN? The numbers on the top aren't pointing me to anything useful.

A serial programming interface chip of some sort, maybe?  What's that connector outline next to it?

Edit:

Tag-Connect TC2030-MCP-NL

Yep, the legend next to it appears to say "PGM".

Here is Belton's datasheet:

I will order for stock ASAP.

That price doesn't seem too much - it's a bit of a game-changer. I like that the stereo chorus has 90deg LFO phases rather than 180deg although the synth brigade might prefer a 180deg version like the Juno chorus.

[Mark Hammer]

180-degree countersweep can get tiresome and distracting.  90-degree won't feel as strongly periodic.  Mixed down to mono, countersweep isn't so bad.  My love for the Boss DC-2 is deep.  But when things go stereo, strong wide countersweep isn't necessarily a recipe for aural pleasure.  One doesn't have to spend much time with an Ibanez Flying Pan to recognize how headache-inducing the overt back-and-forth of 180-degree countersweep can be.  That said, countersweep is still better than sum-vs-difference outputs.

I'm trying to make up my mind on how this could be better than a fv1 with an eeprom....

10ms to 1000ms.......delay, with tap tempo,  yup i'm in......

[bluebunny]

If you're interested in a delay, Rob, I will happily big-up Tom's Digidelay.  The delay time control is a simple CV, which could doubtless be made to wobble with a bit of (one of Tom's) LFO (chips).  (In fact, all the parameters are CVable.)

That's not taking away from this new Belton gizmo, of course.  (Do both!)  Thanks for posting the datasheet, Steve.

I will order for stock ASAP.

I will order at least one and start a run of PCBs ASAP

[Kipper4]

Has anyone tried these? or even seen a data sheet for it please guys.
Thanks

Thanks Rob.
Looks sweet might have to trial some.

I wonder whether the LFO on the chorus will be accessible...or replaceable. And whether it would be possible to get 'wet' only signal. How much meddling are we going to be able to do with these things? Or is everything taken care of internally inside the chips?

[anotherjim]

The datasheet implies you only get what's programmed into it. However, it does appear to have a programming port typical of embedded processors. I suspect it's going to be the big customers that get the ability to load or order custom programs.
On top of that, what you can do in the control of your features will also be limited by the fixed number of GPIO pins.

Cool Audio V1000 & V4220

so basically its this, just 'presets' no control?..

I was thinking about this more yesterday, and I think I'm going to go straight for the Coolaudio chips instead of waiting for the module to play with. Everything I do lately is SMD anyway, it wouldn't be that hard to basically make that eval circuit. It looks like there are some upsides and downsides to both ways of doing this. Like the built-in tap tempo and pot hookups is super convenient, you can't get that yourself without coding. But on the other hand you get 16 effects instead of just 4:

- small hall reverb
- big hall reverb
- room reverb
- church reverb
- reverse reveb
- gated reverb
- chapel reverb
- spring reverb
- phaser
- flanger
- echo
- chorus
- early reflection
- big ambience
- stereo delay
- slap-back delay

So you get less control over the parameters of the effects (again, unless you feel like coding), but you get more effects total. So yeah, I'm trying this out. Just ordered a couple V1000 and V4220, I'll get working on a board layout and keep everyone posted

[deadastronaut]

cool, look forward to the results......nice one nathan

[vigilante397]

Finally got around to that PCB layout. I got the chips in last week, so I'll verify my footprints before I order boards, but I expect to send them out in the next day or two. I didn't add much to this board above what was in the reference design, because I wanted to make sure I can get it working before going crazy with it. With the next version I'm planning to add a clean blend so you can control how much effect you're putting in, and I want to add a small OLED display that tells you what effect is running, as well as a momentary footswitch to cycle through the effects (controlled by Arduino of course), and it will all be form-factored for a 1590B. But for now the effect will be set by a quad DIP switch.

Anyway, this is what the board will look like:

Is that programmable?
