How do I know if my Synergy is a Series I, Series II, or Series IIi with the new Amplifier Board?
The original Synergy had a red volume display and simply had the words "SYNERGY PREAMPLIFIER" printed on the back panel. The Series II version of the Synergy had a red display and the words "SYNERGY PREAMPLIFIER SERIES II" printed on the rear panel. The majority of Synergy IIi preamplifiers have the words “SYNERGY PREAMPLIFIER SERIES IIi” laser engraved on the rear panel.
The Synergy IIi units with the new amplifier board can be identified by the green or blue volume display.
