IMPORTANT NOTICE
There are two versions of the IRS Epsilon system
The following part numbers were changed to reflect this:
EPSILON LOUDSPEAKER (Early) - IF30003
EPSILON SCU (Servo Control Unit) (Early) - IF80008
EPSILON LOUDSPEAKER (Later) - IF30003A
EPSILON SCU (Servo Control Unit) (Later) - IF80008A
The two components cannot be "mixed", i.e. the early version loudspeaker cannot be used with a
later SCU, or vice versa. Damage may result to the Epsilon System or to the customer's power
amplifiers if this is attempted.
