Eventide H8000 (Unknown Years)

A programmable, multi-channel effects processor with FireWire connectivity, sold as an Ultra-Harmonizer for professional audio.

Overview

The Eventide H8000 is a multi-channel effects system for high-end studio and live use, sold under the Ultra-Harmonizer name. It handles complex audio routing and connects to computer-based setups over FireWire. It is programmable and mounts in a 19-inch rack in a 2RU steel enclosure.
