The shape of the KT curves isn't far off when the bandwidth is turned all the way "broad". The shape is far too broad when the bandwidth is all the way "sharp". The lack of the right number of taps makes the frequency different than a passive EQ with the right inductor. I would ASSume KT are changing cap values so the frequency should be right but the bandwidth (by using the same inductance value) will be different. Pultec did this too with the EQP-1R. As far as I have seen Pultec does this in the EQP-1A where 10k and 12k share the 33mH tap.

Funny enough John...I was recently thinking about how Scott Liebers, Dan Deurloo and myself came and hung out with you a bunch of years back. We brought the ML's for you to hear and we were all blown away. You bought them and I think sometime thereafter sold them because...that's what you do! Well, I DID buy a Sumbus. Yes you did! <3

Can you use them as a line level source to track synths and drum machines thru? Sounds like you can if people are mixing with them. I plan to do both. Yes absolutely you can. FYI, I am low on faceplates and L-brackets for the ML2's. I literally just placed an order but expect them to be 6-7 weeks out before fab is done and screen printing etc.

We haven't officially announced the details yet but Coil Audio, Roswell, Pulse (Pultec), Placid, Stager, PatchRat and myself will be cohosting our summer NAMM bash at The Tracking Room on Saturday July 20th 4pm to 10pm. Always a good time to for an RGO hang!

How much do you think Jeff wants for that $500 mic? Well, maybe if you add a 2 in front of the 5 and add a zero LOL

People play fast and loose with what they call mics these days (like calling an ioaudio MK67 a "U67", it's close but it's not) hence my not being positive about the era of mic used. It was a real Telefunken ELA M 251. We started out with the one at Sheryl Crow's studio, but when we moved over to Sound Emporium and to my studio we rented one from Blackbird. We had to try out 4 or 5 of them to find one that matched. If you and Kacey wanna checkout my Dolly 251 I'd be down. It's spectacular. I think it must be the magic spitle Dolly blew into it

Johnkenn, you should give Jeff Hedback a call. He does phone/remote consultation. He could for sure help you flatten out the bottom end. Jeff is an awesome guy. He designed my room and has done stuff for dandeurloo, drbill, BradM and many more. He's the acoustician for the blue collar man.

....I used to work at a Studio that had two different API desks and I was even taught the supposed “Aerosmith guitar trick” of diming all three bands by a pretty established engineer. Sounds amazing.... Can you elaborate on this? Just curious.

So is my understanding correct that, though the 16x2 version comes with 16 input cards ready to send signal to 4 busses (A Left, A Right, B Left, B Right), it only comes with one ACA card (hence, 16x2 instead of 16x4) for the A bus and that you must purchase a second ACA card to take advantage of routing to the second L/R bus (B bus)? In other words, if purchased as is, would selecting the B bus on the input cards of the 16x2 version basically result in the signal going nowhere? If so, what is the cost of purchasing a standalone ACA card to insert in the B bus? I don't think I've seen where that is individually available for sale, but maybe I just missed it. That is correct. It’s an add on. jsteiger Yes correct you are kemosabe. We have a few different B Bus options here capi-gear.com/catalog/index.php?cPath=217_219_221

Yeah, the code seems to work on everything else I've tried but the Coil CA70. What will be next.. jsteiger can i order ML2s somehow??? I need to update the ML2 PCB layout and reorder boards. I've been meaning to do that for many months now but something is always getting in the way. The past few days its been a layout for a headphone amp module. Really good sounding one that'll make your ears bleed if you want them to. HPA500...coming soon.

Very nice to meet you in person and chat a while Jeff. I hope you had a successful show. Also great to chat a bit and meet you in person Keith!! We had fun at the show. Hopefully it will be at least somewhat fruitful!

Thanks Jeff, I am an AES member and this promo code worked for me. Any idea how I can register a friend to attend with me? The AES website tells me I'm already registered and won't allow me another one. I think you can just send him that link. It should be free for anyone.

Anybody planning on going this year? I’ll be there all day on the 16th - let me know who is planning to go so we can all go bother Jeff at the CAPI booth! 🤗 Sounds good! The show starts on the 17th though...

bartacusad the VP28 channel isn't quite the same as the master fader on the mix bus. On the VP28 in line mode you're padding the signal down 35dB, then raising it up through the input transformer, the first op amp, and the output transformer. That feeds the 'channel fader' which attenuates a fixed gain 325 style line amp (I'm guessing +6 dB on the op amp, and +6 dB on the output transformer). So with the fader wide open, you're doing no attenuation before the +12 dB of the second stage. The +12 dB is always there, though. On Jeff's ACA Booster card, the summed signals come into the ACA at -2 dB, the ACA op amp combines them for a 4.5 dB loss, and then adds +6 dB across the output transformer to bring the whole thing to a nominal -0.5 dB. (I think this is where the SumBus box "ends".) In the ACA-BO card, this goes into the master fader which works the same as the stepped attenuator in the VP28, but in the console booster the op amp is set to nearly unity and the final +6 comes from the output transformer. Without transformer insertion loss you have a nominal +4.79 dB output for a +4 line input, which hits the program bus at -2 dB. So - using the VP28 at unity from the SumBus is taking a nominal -0.5 dB signal, padding it by 35 dB, bringing it back up 35 dB through the mic pre (~17 and 6 from the input and output transformers and I suppose ~12 dB from the op amp) to come back to -0.5 dB. Then, bringing the fader to +12 does no attenuation before a second round of +6 and +6 from the op amp and second output transformer respectively. (If you pull the fader back you're actually dropping the signal again, only to boost it again at the line amp by 12 dB). Long way to say, the closest way to approximate the booster on a console is to get a 325 (or a API 535-LA) and set it to +6 dB. Or, get a CAPI card and rig it without the input transformer as a unity line amp with +6 on the output transformer. Not that y'all are doing anything wrong! If it sounds good it is good! Just that there's a lot going in the VP28, even at unity. These numbers are not exactly right. The output of the SumBus is 6dB down so -2dBu nominal. Also, the SumBus outputs are strapped 1:3. The gain staging is of course different when using a VP28 or any of my other 2 stage preamps but the idea is to get as much of that vintage console character as possible. The VP28, VP28-Platinum or Heider FD312 are the best ways I know of to do that. Noise? Sure since we are knocking it down and boosting it back up there is a slight increase in noise but it is for sure nothing to be concerned with and absolutely well worth the effort. bartacusad has been mixing major label records in Nashville for decades. He's mixed on every large format console there is. He has GREAT ears and I trust them fully. If there were a noise problem by following my recommendations he would be the first one to tell me.
