INSTALLATION INSTRUCTIONS

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!

Lastly, the AH99-8ST stands out with its wide coverage pattern and increased power handling capabilities, designed to distribute sound evenly across larger areas. This makes it an ideal choice for installations where wide dispersion and volume control are key, such as gymnasiums or large assembly halls.

All these speakers incorporate advanced technologies including neodymium magnets, mounting options for flexible installation, and durable enclosures designed to withstand the rigors of professional use.
