Pope Flexcore preamp

[thepontif]

Or even just a little black tape on the back of the board if in doubt...or on the surface of the wall in questionable spots. The 16mm pots were a choice I made because they are tough and withstand some abuse...especially with the boards hanging off of them. But they do take up some space. I felt longevity and reliability should be the priority. You know engineering...sometimes you can't have it all.

That's exactly what I did.
Here I come with another question. My second flexcore configuration is the following:
Mike Pope Flexcore - Core 2.2
2-Pickup, 5-Knob*

Master Volume control, with push-pull for active/passive
Pickup Blend control
Treble/Bass stacked control
Hi Mid control
Lo Mid control
According to the description added I should have the following possibilities:
Switchable Frequencies:
The preamp has provisions for 2 different frequency centers for each of its bass, lo-mid, hi-mid and treble controls with the bass and treble control selectable via included jumpers in the cavity and the mid frequencies selectable via jumpers or optional switches.

Treble: +/- 15dB @ 6kHz or 10kHz
Hi Mid: +/- 15dB @ 1kHz or 1.8kHz
Lo Mid: +/-12dB @ 330Hz or 473Hz
Bass: +/- 12dB @ 46Hz or 90Hz
The different pots which were send to me do not have any jumper contacts and btw. no gain trimpot like I had on the EQ-board on my first flexcore (4 knobs 2.2)
Sorry for bothering again.

For the mid boards, the jumpers go on the pins of the green connector. 2 jumpers per connector...only one way to get 2 on there.

The gain trim pot is a mystery. You SURE it's not there? If it's not, it almost would have had to have been broken off at some point. Because I test them all before they ship out of here, and it won't work without the trim pot.

I've received these modules:

and how do you switch the center frequency for the mids with this configuration?

On the stacked low mid / high mid pot is only one green plug?

Mike,
Is the default center freq for the treble 6kHz or 10kHz?

Thx,

I thought about black tape, but I worry about a wire end poking through it. I think about black helicopters, too.

I guess that I should read slower ......

I see in your adobe file that you state to LOWER the bass or treble freq. install the jumper(s).
I would interpret that to mean that no jumper on treble = 10kHz

That's the way I understood it too and I put the jumper as recommended on the bass frequency only. Sounds great!

I did the same thing - I put the jumper on the bass frequency and now it BOOMS !! Way better than any other onboard EQ I've ever used.

I may try the jumper on the high frequency, too to see how it sounds.

The first picture shows everything EXCEPT the EQ board. The stacked mid board and the EQ have the same kind of pot on them, so they look similar but are not the same.

[thepontif]

I ship them with the Bass frequency set low, and treble set high, as that seems to be a more widely applicable setting.

Adding jumpers lowers frequencies.

You're right, there was a problem, it was shipped to me without the EQ-board.

I can differentiate the different pots. My question was, since there's only one green connector in the stacked low- and high-mid modul, how I could change the center frequency by adding jumpers. It's the one on the right side on the picture.

There's a green connector, which you can see and a purple connector, which you can not see on the picture. So far I understood you, I would have to add two jumpers on the single pot systems (as also described in the flexcore manual). How to deal with the stacked pots is not mentioned.

That link was no good. I'm really confused, though. Because you said that the EQ board for the second preamp didn't have a gain trim on it. Now you're saying it didn't come with an EQ board. Can you clarify for me?

As for the mid jumpers, on the stacked pots, the green connector is for Lo Mid, and the Blue is for Hi Mid (intuitive to the shaft positions)...just so there wouldn't be two connectors on the same board that had different functions and were the same color. The oranges are the same because it doesn't matter which one goes to which orange on the EQ board, and they're both used all the time anyway.

Sorry my mistake. I named it EQ board because I had the idea, that the one in the middle had to be the EQ board, since there were beside of this one, a volume, hi mid, low mid and the balance pots. In my first preamp the stacked bass - treble pot was on the EQ board.

On this picture you should see what was shipped to me. Sorry for being confusing...

[thepontif]

Again, the link is no good. Sorry!

And now?

[thepontif]

Hmmm. I don't see an EQ board. From whom did you buy these?

You're right, there was a mistake when the preamp was prepared for the shipping, and the missing part should already be on it's way to me. At least I didn't ask questions for no reasons.
I don't want to blame someone publicly for this minor error (I hope you agree, don't you?).

[thepontif]

Cool. Mistakes happen. A good company just takes care of it. I don't think anyone would hold it against them.
