The Voiceprism is the second product of a collaboration between TC Electronic of Denmark and IVL of Canada; IVL being the vocal processing specialists who made the original Vocalist range of auto harmony products for Digitech. It draws together TC's expertise in effects processing and IVL's pitch shifting wizardry to provide the live or studio vocalist with a one box solution combining a voice channel (preamp, EQ, dynamics), intelligent four voice harmony generation, and vocal effects.
Voiceprism is a 2U rackmount processor with a slightly raked front panel for ease of access. There is a large LCD display, with four 'soft' knobs below it relating directly to on screen parameters. A pair of Menu Tab buttons navigate between menu pages.
The metering for the input is located to the left of the LCD screen, where there's also a clear, numerical readout of the patch number. Processing within the machine is all digital, following the analogue mic/line preamp, and, in addition to harmony generation, the signal path of the unexpanded Voiceprism includes compression/gating, two one band equalisers and two effects.
