AI001 Multiple Features
The AI001 Multiple is passive, so it requires no power. (It operates using the voltage from its inputs.)
The top four jacks form channel 1, and the bottom four jacks form channel 2. A signal patched into one jack is distributed to the other three jacks in that channel.
When nothing is patched into the 5th jack, channel 1’s signal is also distributed to jacks 6, 7, and 8. When a cable is inserted into the 5th jack, that signal is distributed to jacks 6, 7, and 8, and the module functions as a 2x4 multiple.
Included Accessories
- Screws
- AI Synthesis sticker
