SPEAKER CABLE RECOMMENDATIONS AND CONNECTION INSTRUCTIONS
Wire Gauges (8 Ohm operation)
For very short distance speaker cable runs (less than 25') #16-gauge, stranded, twisted pair speaker
cable may be used. For speaker cable runs between 25' and 75', #14-gauge, stranded, twisted pair
speaker cable is recommended. For speaker cable runs greater than 75', #12-gauge, stranded, twisted
pair speaker cable is necessary. For runs exceeding 150', please contact tech support for proper wire
gauge or other installation solution using the Atlas Sound AF140 autoformer.
15" models AH5040S, AH9040S, and AH6565S input connections are provided on a convenient recessed
terminal block located on the bottom of the loudspeaker. This terminal block includes a clear weather
resistant cover which should be re-installed after terminating the speaker cabling to prevent corrosion in
outdoor applications.
8" & 12" models include a built-in, high effi
ciency 60 Watt 70.7V transformer. 7.5, 15, 30, and 60 Watt
taps are available on a convenient recessed terminal block located on the bottom of the loudspeaker.
A removable jumper and additional pole on the terminal block is included for 8 Ohm direct coupled
operation. This terminal block includes a clear weather resistant cover which should be re-installed after
terminating the speaker cabling to prevent corrosion in outdoor applications.
Allow an adequate service loop for this connection to allow tilt of the loudspeaker. If the speaker is tilted
above parallel to the ground, the speaker should be installed angled slightly down for water drainage — in
other words, the product should not be installed tilted upwards!
