9 setting up and using the servo amplifier setting up your servo amplifier is a simple procedure which takes only a few minutes: 1. Remove all packing materials (save them in case of need for future service) and decide where the amplifier is to be physically placed—it can be used free- standing or m...

Appendix e: bridged mono mode (servo-550 only) the servo-550 amplifier provides a rear-panel switch that allows it to be used in a bridged mono mode. When this switch is placed in the “stereo” (up) position, the servo-550 functions as a true stereo amplifier, where both of the two independent amplif...
