- Page 11 When a Link switch is enabled, the Channel Input’s unbuf- fered source signal is transmitted in parallel to each linked Channel Output. This causes the Channel Input’s imped- ance (normally 10 kOhms for one MM-4XP) to be reduced for each linked Channel Output. For example: Galileo 616 ■...
