[NEW] Serge Resonant EQ for Euro by R*S

Post by nordlead » Thu Dec 10, 2015 7:21 am

Hey guys,

when the Serge VCFQ filter was released a few weeks ago, some of you requested a slim version of the Resonant EQ - which I thought was a great idea! :guinness:
So here's the Random*Source adaption of the amazing Serge Resonant Equalizer (EQ) in Euro format - under license and with the kind support from Serge.

The R*S version adds an input mixer with 2 inputs that can be built/used to attenuate or amplify/distort the input signal(s) before they are sent into the EQ and a Feedback section (knob and phase switch) which allows to feed back the output signal or the inverted output signal (depending on the Phase switch). Adding inverted feedback leads to interesting phase cancellation/filter effects - unlike the “normal” feedback, level decreases and the signal thins out.

Here's a simple demo using the Euro version and only very simple (static) wave forms as input:

Currently the Euro version is available as a front panel (screen printed, 18hp) + pcbs kit. Module depth is < 40mm (~1.5").

See the R*S Resonant EQ page for more info - that's also the order page.

Worldwide / international shipping as an Express Letter (signed, insured) is € 9. Here's a picture of the kit contents:

Kits are shipping now :party: - as long as stock lasts.

Fantastic - this one is a definite buy, i've never liked the slider version.

Gonna get it right now...

Can anyone post the Mouser BOM Cart and the link to the other components that Mouser don't sell? I really suck at getting components... :(

Ive got a lot of revision to do for exams, however if i have a few hours spare tomorrow ill make a mouser car and post it here.

Simply because i was going to use Rapid however having a quick look they don't have Burr Browns and theres a few capacitor values i can't find either so i'll reluctantly use Mouser instead.

Well... I expect that those 1k resistors that you can omit connect to the individual outputs (they connect to ten unused holes on the pcb).

Ridiculous.

My Serge panels are getting nervous. If the TWS and WVX come out there might be some upheaval.

Actually, this would be fantastic to know. There is no way I can fit these into my main case, but if some more bits are coming I might just go ahead and revive my little second case just for this line of modules.

That's correct - however, please note that this is untested, for experimental purposes. Also, not sure if the amplitude of some (of the higher) bands is fully in line ...

Many thanks for your feedback, guys! (pun intended ;-)

In general I'd rather not announce anything until it's here and ready to ship (- everything else would spoil the surprise!) However, this time the situation is a bit special - the ResEQ was intended as #4(!), front panels and pcbs for #3 have arrived last week, :party: but pcbs are currently in SMT production queue and it's unclear how quickly they will get back. Here's a hint:

Module #3 is also 18hp (and is SMT again) ...

:omg:

I expect it's a DUSG.

Amazing! I'm probably going to sell my wide Res EQ mk. 2 as I don't really need the individual outs. However, I'm totally going to wait for the Thonk kit this time around. Sourcing the caps and resistors last time was a decently time consuming process.

Congrats on the awesome work on all of these. Removing the wiring pre-requisite really opens up these designs to builders with less time on their hands. Plus, the panel designs are absolutely gorgeous.

any chance of a breakout panel for that in the future?

Sorry to disappoint you! - ... DUSG is a bit further down the list, probably rather in 22hp ...

If you're in the USA, the last time I ordered the polystyrenes, they were from here:

I'd love to sell my mk2 and jump on this. I could use the room in my case and I really like your design aesthetic, but then I remembered how half the time I use my mk2 I'm cutting and boosting four or five bands at a time with the sliders. Can't do that with knobs :[ #realproblems

I'm also for knowing what's coming in the near future. I love a good surprise, but I like knowing to hold off on a wavefolder build because there's a Serge module coming soon even more :hihi:
