Lexicon PCM91 Digital Reverb Processor

Digital reverberator offers highest quality reverbs in compact, affordable package with powerful interface which allows both easy access and wealth of programming capabilities for the sound designer. All of the features of the acclaimed PCM 90 are included, plus full AES/EBU I/O, Dual Reverb algorithms, and presets with dynamic spatialization effects for 2-channels. One of the stunning advances in the digital reverberator is the ability to create incredibly realistic small spaces. For both music and film sound, it is often vital to have the ambience of a phone booth or very small drum room. In the digital reverberator you can create them with a reality never heard before from any processor other than a Lexicon.
