The Series II Synergy added a set of output transformers to the original Synergy to lower distortion, perform impedance matching between preamp and amp, and decrease noise significantly, and also included a second set of Main Outputs and Record Outputs to allow for bi-amplification and multiple tape or recording systems. The additional outputs are connected in parallel to the original outputs and cannot be controlled separately or independently. The Series IIi Synergy replaces the original amplifier board within the Synergy and Synergy II with a new, surface mount designed amplifier board and green or blue displays and indic
