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 antennas or other sources of interference or when the
amplifier is being used for paging from a telephone system, the amplifier may require shielded
output cabling to prevent audio feedback or interference.
