    I know this has something to do with the Low end, but what is it? What does it do? What should the DIP switch settings be?

    Are you sure it isn't an Allen Digital Reverb?

      I don't know - I'm new. I assumed since it is after the Low Pass Matrix it has something to do with that.

      Digital Reverb makes sense. How do you adjust it? What are the DIP settings?

        The DIP switches have something to do with reverb length, as I recall. The pots are marked and their function should be self-explanatory. Adjust to taste, but make sure the reverb is not being overloaded or you'll get digital distortion and clipping.

          Hey, here's a crazy thought: drop a line to Allen in Macunge, PA!

            The DIP switches control the length of reverb and whether is front or back reverb. Changes do NOT take effect until the reverb tab has been cycled off/on. I don't have my manual handy, so I can't say which ones do what.

            The low pass filter prior to the reverb is to cut the highs from coming into the reverb unit. This matches what physically happens in an acoustic space, where highs are readily absorbed and reverb happens in the bass and midrange domains.

              Having a bad hair day Jan? You are very well educated in most all things organ and usually quite helpful. Please don't scare off the newbies. We need someone to take care of our charges after we're no longer here. Smile....Bill

                Search, what are you talking about?

                  I think that Search was perhaps implying that those of us that respond should have at least a small amount of information in our response beyond a simple reference to look elsewhere. He also acknowledged excellent responses in that vein from the past and the expectation of even more in the future. I thought it as tactful a "suggestion" as organ folk are capable of.

                    I fail to see how suggesting he contact the (still extant) builder of that organ can be construed to be scaring off the newbies.

                    If he was asking a question about a Wurlitzer feature, would I be criticized for suggesting he contact Morelock's?

                      Thanks Kurz, but I believe Jan is still in the prankster mode. That's ok, he'll be back with us soon.....I hope!

                      Anyway, if we could all solve our problems, or perhaps build the perfect instrument just by referring to the manufacturer, why would we need this forum? Or any of the many talented people who contribute here?

                      But, we can't....and we do. So, please purchase a ticket and hop back on the train with us. K?
