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.
Cabling and Amplifier Selection The EMS-81X is designed to be used with professional power amplifiers providing the following power outputs: EMS-81X 500W/channel into eight ohms...
– we would stress that the higher the filter, the safer the loudspeaker will be. If you are in any doubt over suitable settings for your EMS-81X, please don’t hesitate to contact EM Acoustics or your local dealer for support and advice.
These fixings allow suspension in any orientation, with the extra point on the rear of the enclosure available for pull-back to obtain the desired rigging angle or as a secondary safety point. The EMS-81X also has four M6 threaded fixings on the rear for use with Omnimount Series 30 or Powerdrive Series 75 installation mounting hardware.
The points on the top of the flying cradle can be used for permanent installations or to secure a hook clamp. Ensure that an M8 eyebolt is secured to the rear point on the EMS-81X enclosure to use as a secondary safety.
Lie the enclosure on its front and remove the four M6 countersunk points on the rear of the enclosure. Position the loudspeaker-side of the bracket as required, reinstate the bolts and retighten. The bracket and EMS-81X can now be mounted using the holes you have pre-drilled.
