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 M-10 is designed to be used with professional power amplifiers providing the following power outputs:

M-10

600W/channel into eight ohms

It is good practice to use an amplifier 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.

Cabling

The M-10 supplied with Neutrik Speakon

NL4 connectors, wired pin 1+/1- with 2+/2- as link-through. It is

recommended that the resistance of your cable is less than one tenth of the nominal system impedance. Given

below are the recommended maximum cable lengths for different cross-sections and impedances.

A small power amplifier working too hard is more likely to damage a loudspeaker than a large power amplifier

working within its operating range!
