SYSTEM SET-UP
Safety Considerations
Loudspeaker systems are potentially dangerous objects if used incorrectly. Please ensure that you read this
section fully, and contact EM Acoustics or your local dealer should you be in any doubt over correct operation
procedures.
Professional loudspeaker systems are capable of producing damage-inducing sound pressure levels, and hence
care should be taken when setting your system up, particularly when it comes to loudspeaker placement within a
venue. Damage to the ear can result from levels above 90dB under prolonged exposure.
Cabling and Amplifier Selection
The i-Series products are designed to be used with professional power amplifiers providing the following power
outputs:
i-8
600W/channel into four ohms
i-12
2000W/channel into two ohms OR 1000W/channel into four ohms (dual 4-ohm mode)
It is good practice to use an amplifier with a power equal to the program power rating of the loudspeaker – so as
to retain sufficient headroom and good dynamic range. Care should be taken during operation to avoid amplifier
clipping – as this can cause serious damage to your loudspeakers. If in doubt, please contact your dealer who will
be happy to assist you in correct amplifier choice and setup.
A small power amplifier working too hard is more likely to damage a loudspeaker than a large power amplifier
working within its operating range!
