Page 7: Cable Requirements
CABLE REQUIREMENTS Output cabling need not be shielded in most cases and should be of sufficient gauge to minimize losses due to the resistance of the wire over long runs (insertion loss). Cable thinner than 18 gauge is not recommended. Long runs require 16 gauge or heavier. In some cases, where the output cable is run in close proximity to unshielded intercom cables, electrical cables, radio transmission antenna or other sources of interference or when the amplifier is being used for paging from a telephone system, the amplifier may require shielded... - Page 8 If Sum Wattage Total is between 217 and 240 Watts If Sum Wattage Total is between 241 and 288 Watts * RMS Amplifier used in conjuction with Speco Technologies’ P-240A Power Booster Amp Speco Technologies 200 New Highway, Amityville, NY 11701 Web: www.specotech.com...
