Lexicon PCM81 Digital Effects System
This unit provides effects with uncompromised stereo reverb and several voices of additional effects. A full complement of Pitch Shifters provides doubling, quadruple-tracking, chorus, and pitch correction within a range of up to three octaves (up or down) - in one cent increments, as well as unique special effects. Three hundred presets give instant access to pitch, reverb, ambience, sophisticated modulators, over 21 seconds of delay time, and dynamic spatialization effects for 2-channel or surround applications.
The PCM 81 features two digital signal processors: Lexicon's proprietary Lexichip™, to run the reverbs, and a second DSP engine to handle the other effects. With 24-bit internal processing, a true stereo signal path, balanced analog I/O, full AES/EBU and S/PDIF digital I/O, the ability to mix analog and digital inputs together, and extensive modulation capabilities, the PCM 81 offers an enormous range of studio quality effects.
Pitch FX and Vocal Fix algorithms and presets are built into the PCM 81.
