Getting Delayed with A/DA
Harley Hexxe:
Okay Gang,
Rather than posting these conversations in the G.A.S. thread, I'm starting a new topic to continue the discussions about the ADA delays here.
Just to bring this into a little more focus, I'd like to start with the Digitizer 4 and it's connections regarding a "Stereo" setup. In the manual, they refer to this as a stereo setup, yet from my understanding, it more of a phase inverted mix if you use output connections A and B.
Output A is the output mix of dry and wet delay signals while output B is a mix of dry and phase inverted delay/effect. Now, I've always looked at this as a physical connection to get a phase inverted effect from the Digitizer 4, since it doesn't have an "Invert" button on the front panel like the S-1000, or the "i" series delays before it. If you use the Invert on any of the older delays, your signal is all midrange with no highs or lows, and has a very Lo-Fi quality. Wouldn't this be the same effect you would get from the Output B of the Digitizer?
Since the manual doesn't touch on this subject at all, how would you do your physical connections with this setup? Keeping in mind that the D4 was the current delay ADA was making at the time the MP-1 was introduced, and the MP-1 only had a Mono effects loop, how would you get your "Stereo" (or dual Mono) effect from that? Hooking one output to the loop and the other direct to the 2nd channel of the power amp?
On the other hand, if you're using the Classic or the MP-2, would you return the Output B to the 2nd loop return, or go again, directly to the power amp?
Let's see what we can come up with.

Hey Harley :wave: , good topic :thumb-up: . If you take outB to the poweramp, you'll loose the preamp stereo-ness and particularly chorus (but would work). But hey they released it back then, how did they intend it to work ? Easiest solution IMHO is us a desk, mono send stereo return, easy to mix and match, run unit full wet, and then assign the returns to the reverb (as well as the dry)..... (part of the reason I've always used a small desk in my rig). With MP-2 you could use send 1 and both returns (it's good that way) you can also plug your MP-1 into the MP-2 returns and just pick up the cab sims.
Some thoughts on inverted signals, which is also how the ADA preamps do pseudo stereo (as I understand it), obviously when you invert a signal it is now totally out of phase with the original. So when you combine them they will cause quite allot of phase cancellation (particularly the bottom and top end as you said earlier (unless you can keep it full wet and mix it in)), this is probably more "surgical" while it's still electrical (ie within various units), when it's in the air (inside and outside cabs) it's probably a bit less :dunno: . If you go with hard L/R pan (and keep them separated electrically (ie strick L/R signal paths)) and let them combine in the air outside the cabs, and keep the cabs "at least" their own width apart (stops infinite baffle coupling (and more cancellations)), then it can work well and sound great :crazy: anyway my 2 cents worth

Hey Richard,
Yes, they do mention using the D4 in a mixing console with the stereo setup in the way you described just now, and of course that would be great for live mixing or recording in that sense. My question was more geared toward using it in my guitar setup with the MP-1.
I'm sure I can mix the signals back in the Classic and the MP-2 through the loops to get the full preamp effects, but the manual didn't go into any detail about how to use it with a live rig like that, so some experimentation will be in order.
When I referred to the midrange tone I got, that was in direct reference to how it sounded when I had the S-1000 in the loop, and pressed the "Invert" button on the front panel. It sort of made me think of how my rig would sound through a telephone call.
I have no earthly idea how ADA intended it to be used with the MP-1, in a stereo configuration. This is why I was speculating about the 2nd channel going direct to the power amp. At the time, I believe only the B200S was available with the MP-1.
At the time when the MP-1 came out, the only effects processors that were being made by ADA was the Digitizer 4, the Pitchtraq, and the MQ-1 Programmable EQ, ( I'm not sure if the MQ-1 was using MIDI yet, I think that came later).

The MQ-1 is midi compatible, it even has the same "midiboard" as the mp-1.

I remember years ago seeing a few auctions on Ebay for those that were described as non-MIDI. Maybe the first few didn't have it? :dunno:
