This compact DSP Ambience Processor™ features two Cathedral reverb algorithms along with eight additional high-quality effects, including chorus and Leslie (rotary speaker) simulation.

Building on the success of our original DSP processors, this updated model retains the trusted mix and input level controls while adding a second audio overload indicator LED for better monitoring. Measuring just 3.5” deep × 5” wide × 1.2” high (including mounting ears), it delivers a remarkably natural and spacious sound that far surpasses traditional spring reverbs or most standard digital reverbs.

You can run multiple reverb effects in parallel or in series for even richer results. Additional creative possibilities include the Traveling Wave Generator™, which creates the same continuous phase shift produced by a real organ pipe. When combined with the Cathedral reverb, the results are truly phenomenal.

The DSP Ambience Processor is compatible with virtually any organ or audio system that has access to a 120VAC power outlet (a switched outlet is recommended). It works with early Allen organs (including MOS 1, 2, ADC, and MDC models), newer Allen organs, Rodgers organs, and most other organ and audio systems equipped with RCA connections.
