Amplifier Considerations
Consult your amplifier owner’s manual to confirm power output at the rated impedance.
15" models: AH5040S, AH9040S, and AH6565S and other models used in 8Ω configuration. Each model exhibits an 8Ω (nominal) impedance.
(x2) AH models paralleled will present a 4Ω load to the amplifier.
(x3) AH models paralleled will present a 2.66Ω load to the amplifier.
(x4) AH models paralleled will present a 2Ω load to the amplifier.
ATLAS SOUND speaker system specifications list RMS power handling.
As a reference peak power = RMS x 1.414.
These ratings should be considered in selecting the best amplifier to power the speaker system.
For general use, amplifier output should match or exceed the RMS rated power of the speaker system: (250 Watts for the 15" AH models, 200 Watts
for the 12" models and 100 Watts for 8" models). For increased headroom and dynamic reproduction, the amplifier’s output should match or exceed
the peak power rating of the speaker system (354 Watts for the 15" AH models, 283 Watts for 12" models and 141 Watts for 8" models). In situations
where experienced professionals are operating the speaker system with proper limiting and frequency control devices inserted into the signal path
and adjusted properly, amplifier output may meet, but should not exceed 2x the RMS power rating of the speaker system (500 Watts for the 15" AH
models, 400 Watts for 12" AH models, and 200 Watts for 8" AH models). Utilizing the Atlas Sound model CP700 power amplifier will allow you to
easily match required power ratings for lmost any installation. Visit www.AtlasSound.com for more details on this product.
