Analog Delay racks???
Anyone know of any current production analog delay rack gear???
Klark & Teknik DN36 Analogue Time Processor.
I done got me one of these:

This is the DN36. There is also a DN34 which has less features but still sounds good, from what I've heard. I'm inclined to believe it since the 36 & 34 share much of the same components.
The 36 allows for cross-channel feedback. The delays on Channel A can feedback to Channel B and Vice Versa.

The DN-36 is stereo while the DN-34 is mono. The DN-34 uses SAD-512 BBD chips and is only capable of short echoes up to about 75 ms.Kent wrote:I done got me one of these:

The DN-34 has two separate delay lines that can be run in series or parallel. You can invert the polarity of each dl and mix them together to create phase cancellation effects.
There is a separate modulation depth-control for each dl, plus an external mod input on a weird tuchel connector round the back. I keep meaning to wire up a cable for mine but never seem to get around to it ...

Actually, I now think it's a 6-pin DIN connector (not a mini-DIN). Does anyone know the pinouts for this connector, or have the service manual? I'm going to try emailing Klark Teknik for the info, but I don't hold out too much hope...Ranxerox wrote:There is a separate modulation depth-control for each dl, plus an external mod input on a weird tuchel connector round the back.

Actually I'm gonna eat those words - Klark Teknik got back to me post-fucking-haste with a .PDF of the manual - superb service.
The 6-pin DIN connector gives you:
-Separate delay-time modulation CV inputs for the A and B delay lines (10v swing);
-Modulation CV output from the internal LFO (7v swing);
-0v, Pos 15v and Neg 15v power from the internal rails (? Up to 20 mA - This is probably enough to run a few MOTM or MU modules from, hmmm)
Now I just need to wire up a break-out box or cable...

The DRS-78 is awesome, actually all that old Dynacord stuff is cool. They did an amazing echo unit called the SRS-56 which I believe could do cross-channel feedback and primitive reverb-type effects. Not sure if it was analogue or not.MicroFi wrote:I've got a Dynacrod DRS-78 which I like a lot!
A bit noisy maybe, but it sounds soooo grungy and dark 8_)
There are some great old digital delays around as well - Eventide H969, Bel BD80, Deltalab Effectron II, Roland SDE, Korg SDD-2000 etc. I have a BD80S which is crunchy 12-bit, sounds great on synths.

agree with Ranxerox, those old Dynacord effect units just rock.

i can just recommend 80's VRS-23 - it's a "vertical" (whatever it means) delay and echo device, 2U rack space. delay mode is mono, and echo is fake stereo (but sounds really wide). it has also some inner LFO circuit for modulation. seems there were 2 generations of this device and it's reasonable to get them both as they behave quite different:
older one, with black front panel - you can force the endless feedback very easily - the unit becomes a great noise source itself. rumours are they die suddenly due to some ageing element inside.
another version has a white front panel, it won't make feedback but sounds much cleaner and act more stable. i use it almost every session.

It has trigger-ins, which makes you able to change between 3 different delay settings.
Perfect to use in combination with the modular

I have the old version and same shit here ....mantiwhore wrote:i have the white version VRS-23 and can't force it to feedback :(
Gladly my unit isn't noisy

I have also an Ibanez UE405...
This unit has less controls than the VRS-23 and the VRS-23 does has less controls than Dynacord SRS-56 or TAM-21. The SRS-56 and TAM-21 does have a cv input for the regeneration.
The SRS-56 and TAM-21 are both on my wantlist

I owened a SRS56 and found it not very interested against my VRS23 which has endless feedback. Sometimes i´m using my EHX Polychorus as a delay but since i have an Eclipse and a Timefactor all these old units are only slightly in use. You can tweak every parameter of the timefactor via CV or trigger!
If your system doesn't sound good enough, you haven't spent enough

Scaff, you just saved me a few bucks - found an SRS56 on Craigslist today at a great price, but I already own and love the VRS23. So no need to rush out and buy this heavy piece of echoes.

Does this mean the cv input controls the feedback level? Definitely not the rate?SMS303 wrote: The SRS-56 and TAM-21 does have a cv input for the regeneration.
I'm wondering whether any of these rack analog delays have cv control of rate. Because I want to use my analogue effects with my modular (Roland PH830 phaser is great for this)
I know the Boss DM300 does, but I'm wondering if any others do.
Anyone know?
