*If the tweeters used are supplied with passive crossovers which have
protection circuits built in, keep these crossover in-line to maintain 
protection from burn out..
Because a dedicated tweeter amplifier is being used this system the Frequency
Multiplier switch must be set to 20x. If you are using passive crossovers on the
tweeters, it is not necessary to set the switch to 20x.
