THIS DUAL CHANNEL AMBIENCE PROCESSOR CAN BE ADDED TO MOST ORGANS TO ENHANCE THE LISTENING AREA TO SOUND LIKE A LARGE CATHEDRAL. ONE UNIT SHOULD BE USED PER TWO  ORGAN CHANNELS. ADJUSTMENTS FOR HALL SIZE AND AMOUNT OF REVERBERATION. Perfect companion to the stereo Traveling Wave Generator TM. Adding a 2nd DSP in series for the antiphonal organ produces realistic large cathedral time delays. No programming is necessary, simply change jumpers to change the pre-set reverb algorithms. Only 1.25" high X 5.5 inches wide (4.25 without mtg flanges) X 4" deep!

Here is a testimonial:
"Stan--
Just wanted to follow up. The installation was very easy-- I used audio cables that are long enough to allow me to put the unit on top of the organ for easy adjustment. When I get time I'll do a more permanent mounting under the manuals.
 The DSP has improved the sound of my Allen more than I dared to hope. It really sounds like a very good organ installed in a large church with live acoustics--even with the headphones. It makes classical organ literature far more playable, and it makes my practice time much more effective because it sounds so much more like the pipe organ at church.
 Thank you very much for your advice and for the great product! I'll know of at least a couple of churches with similar organs and dead acoustics; I'll be recommending the same modification for them.

Hi Stan,


Your welcome.

I received the DSP Ambience Processor last week and did the installation on Friday afternoon. The installation was quick and went very well because of the small size of both devices. I installed both devices inside the organ near the top right-lid area where I could access them easily and make adjustments to both units without having to pull off the back of the organ panel. To access both devices for adjustments, I just pull the organ lid up and perform the adjustments and pull the lid back down; quite easy for me. 

With the newly installed DSP Ambiance Processor and the Traveling Wave Generator, I am able to fine tune both devices, and the Allen T15A never sounded better. The Allen T15A organ's voices now sounded much richer, fuller and grander than they did before. I just couldn't believe the richness of sounds I was deprived of all these years. I now practice on it everyday; thanks a million for inventing such awesome products for the analog organ and with easy installation.

In regard to the MIDI system, I received my Tech Manual for the Analog Allen Organ on Tuesday afternoon along with your good news. The connections' points for the MIDI seem very easy and straight forward. However, my one question is: Will the Allen pedal board connection be included along with the two manuals/keyboards and stop connections on the new MIDI board?
Sincerely,
Barry
