6 Preparing modules for installation
6.1 Recommended preflight procedures
For any sound system, certain checks made at the installer’s place of business can prevent
expensive on-site delays. A short-list follows, and sets the stage for proper array performance:
1. Unpack all loudspeakers in the shop.
2. Check for proper model numbers.
3. Check the overall condition of the loudspeakers.
4. Check for continuity at the loudspeaker inputs.
It is a good idea, once on-site and the loudspeakers are connected, to check again for
continuity at the power-amplifier end.
6.2 Module configuration
While modeling an EVA system in the PREVIEW Loudspeaker Software, you can shade the
loudspeakers with the high-frequency attenuation card in the input cup, or with optional
attenuation modules. You need to perform this shading manually when the system is rigged
and suspended.

Notice!
It is possible to complete shading adjustments and installation of attenuation modules at the
installer’s shop. Make certain that EVA modules are properly identified to avoid misassembly
of the array in the field.
Use of high-frequency shading
An EVA HF shading switch card comes pre-inserted in the “Center = Both @ 0 dB” position,
indicating no shading of either HF element.
To attenuate the top HF element:
– Remove the switch card by drawing it toward you using the central finger hole.
It is possible to remove the switch with the end of a flat-blade screwdriver. Place the
blade end in the switch hole and use the adjacent edge of the input panel as a fulcrum. A
small recess in the edge of the input panel opposite to the hole in switch card facilitates
this operation.
