Behringer 2600

[KSS]

Interesting thing I’ve been running into- when the have the left and right channels going to my audio mixer, if I have the two channels panned center, the spring reverb cancels out. If I pan the channels hard left and hard right the reverb returns/becomes audible.
The non reverberated/dry signal dosnt seem to be effected when panned or not panned just the reverb sound.
Not a huge deal I don’t think because if I’m running it mono I only need one channel, but kind of weird, like the reverb is out of phase between the two channels (but the dry signal isn’t?).

The reverb tank pickup amp goes to the pair of reverb level sliders and then *is* phase split at the reverb preamp inputs. On an ARP this is on Bd4-2.
These two potentially phase cancelling outputs are fed into the left and right 'main' preamps which are both inverting.

The mixer output is also inverted relative to its input and this result goes to the pan section of the circuit where one side or the other sees more grounding to effect the pan function. From this T the two now pan processed outputs -top of T- join the reverb preamp outputs at the 'main' preamps and mix into virtual GNDs there.

Your conclusion is correct. The reverb is split-phased and the main mixer is not.

Thanks for the info!
Why do you think they chose to make it this way?

[KSS]

For the pseudo 'stereo' effect of the split reverb. As you say the main use is mono. In a stock 2600 there's only one tank and the cancellation isn't an issue when using the mono reverb channel's main reverb output.

B100k. It’s the A3 Type, I assume, as you’d have more even travel. But if you find a shop that carries A2 as well, it wouldn’t hurt to get one too, just in case.

Thanks, I'll maybe get more to make the delivery worth it.

I did a video showing some lead sounds you can do on this thing.

Does anyone know a mouser part number for the LED’s used on the B 2600 faders? Interested in customizing the colors on mine a little.

A few pages back (maybe 10 pages?) people are talking about the effects of LED cables on the Behringer 2600. Well I had to grab some and see whats up. Here's a couple things I found you can do with them. They have significant effect on certain patches. This video also shows some weirdness when plugging into the gate output.

By the end you are getting some killer sounds. Thanks for the inspiration!

Glad you liked it! Someone on GearSpace mentioned if you invert the feedback you can get an even more extreme sound but I haven't tried it yet.

the school i teach in just bought a gray meanie, i've already had a couple of sessions with my students. never had the opportunity to put my hands on a 2600 before. this thing sounds great and is inspirational as fvck! i love how you can exploit feedback and the preamp in various points of the signal chain to saturate, the sample and hold and ring mod are great sources of fun too! i theoretically don't need one (i have a lot in eurorack with which i can do similar stuff) but this thing is REALLY tempting!

I've been messing around with LED cables and output to output patching and getting some interesting results. If you retrigger the synth from the LFO and patch an LED cable from the trig out to the gate out you get a varied trigger pattern. I'm using Producer Tools LED cables to do this but it might work with other brands.

[Bata]

I show what the LED cable does to the LFO retrig in this video around 4:40

So, I kinda recall that many modules makers left out LEDs, or only included the essential ones, as they added noise. But now synths are covered in them, and cables have them.
Did LEDs change? the PSU/filtering? or...?

LEDs changed. They became much more efficient which means they don't affect the power supply as much and they don't affect the circuits as much either.

You can think of it like a litter of kttens or puppies where -in the old days- puppy LED was hungry and pushed everyone else out of the way, demanding to be fed. Now puppy LED is content to have only a few bites and let others enjoy the meal too.

LEDs take about twenty limes less -or even less!- current than they used to.

Not sure if this is well known but if you route the -10V to the S/H clock out it disables the sample and hold. You can also send the -10 to the Ring Mod in DC mode and have an lfo or oscillator etc influence how often the S/H is disabled. I will show this in a video in the next day or 2.

[a100user]

Just want to say Bata that I am loving your videos, inspiring

[Bata]

That's really nice to hear! Thank you!

[Happiness Forever]

Yes, agreed, thank you user BATA.

and a hearty shout out to user KSS for all the truckloads of information you’ve been shipping in.
