Tapco PRV-1 is a professional sound processing unit suitable for most applications requiring advanced sound control concepts. It has both balanced and unbalanced inputs and outputs, ensuring easy interfacing with other units, and a fully independent switching of reverb and line signals, allowing for great flexibility. The reverb section offers an exceptionally quiet, natural sound, comparable to much more expensive studio reverb systems. The parametric equalizer permits very flexible sound control, featuring two bands of fully symmetrical non-interacting bands. The PRV-1 can be used to equalize the line (dry) signal, the reverb signal, or both - a feature not commonly found in other reverb units. This allows not only for superb reverb capability but also for an extra two bands of parametric equalization for broad band boost or cut or for extremely narrow band equalization for feedback control, hum and noise elimination, etc.
