The Eclipse V4 from Eventide is a compact multi-effects processor that offers a wide range of depth in its algorithms. Eventide has provided almost 100 algorithms in the Eclipse, any of which can be routed to the two independent effects blocks and then outputted in stereo or mono. It can process audio at 24-bit and handle 96 kHz sampling rates. Digitally, the Eclipse accommodates AES/EBU, S/PDIF, and ADAT Lightpipe. For analog, the Eclipse features balanced XLR and unbalanced 1/4" inputs and outputs. The 1/4" jacks allow for high-impedance instrument signals. The processor additionally includes wordclock I/O, an external power jack, MIDI in/out/thru, and two pedal ports for live performance triggering.
The Eclipse boasts 11 reverberation algorithms and four plex algorithms, all of which are true stereo in and out. This effects processor additionally offers Micro-pitch-shift technology for improving vocal tuning. With the Eclipse, you get an array of delays, 20 seconds of mono looping, and 10 seconds of stereo looping, which can all be combined using the two independent effects blocks.
The Eclipse's user interface is designed to be intuitive and easy to operate. The layout of the knobs and keypad are similar to the H3000 Harmonizer unit's, but with the addition of hot keys to help speed up the tweaking process of the presets. A dedicated tap button can affect the delay timings, LFOs, autopanner speed, or tremolo, enabling you to easily lock into a live performance tempo. You can make your own presets and save them to a compact flash card or the internal memory. Once your presets are saved, the compact flash cards allow you to easily transfer your data from one Eclipse to another, if needed.
