INSTALLATION INSTRUCTIONS
AH5040CD INSTALLATION
Amplifier Considerations
Consult your amplifier owner’s manual to confirm power output at the rated impedance. Each AH5040CD
exhibits an 8 ohm (nominal) impedance.
(2) AH5040CD’s paralleled will present a 4 ohm load to the amplifier.
(3) AH5040CD’s paralleled will present a 2.66 ohm load to the amplifier.
(4) AH5040CD’s paralleled will present a 2 ohm 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 AH5040CD).
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 AH5040CD).
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 AH5040CD).
