What Are Some Techniques To Properly Balance The Levels Between The Subwoofer And Satellites; Specification Questions; Are The Evid Full Range Speakers Protected Against Excessive Input Power; Can The Evid Models Be Use Outdoors - Electro-Voice Premium Surface Mount Speakers Installation Reference Manual

In mono systems (with the inputs of the subwoofer paralleled), the amp views the loads
hooked up to the Left and Right satellite outputs as being in parallel with each other.
Make sure the amplifier can run loads of less than 4 ohms in this situation.
What are some techniques to properly balance the levels
between the subwoofer and satellites?
The required sensitivity balance between the subwoofer and satellites varies by the
musical requirements of the application. A sports bar or health club for example might
require much more bass content than does a low level background music system.
Sensitivity of the satellite section varies depending on the particular satellite model
chosen, the number of speakers employed and the wiring configuration. Higher satellite
sensitivities result in less relative subwoofer level.
It's generally best to position the subwoofer after the rest of the system is installed,
changing its location to achieve the optimum bass level. The acoustic volume level of the
subwoofer can be raised or lowered by moving its position within the room. Beginning at
a corner junction in the room you can enhance bass output by moving the subwoofer
closer to the ceiling or floor; you can reduce apparent bass output by moving it out onto
the center of a wall. You can decrease bass output further by suspending it in the middle
of the room.

Specification Questions

Are the EVID full range speakers protected against excessive
input power?
Yes, protection circuitry is included inside all the 8-ohm models. This circuit gives full-
range protection including the woofer and tweeter. The "t" versions are current-limited
and fully protected by the transformer.

Can the EVID models be use outdoors?

Yes, the full range models are all "weather resistant". They pass MilSpec 810 and are
IEC rated as "splash proof" (IEC529 rating of IP-x4). If possible, it is best to install the
units under an overhang maximize long term performance.
Although not always needed, further moisture protection can be obtained by using the
weatherized terminal covers when the EVID 4.2 and 6.2 units are used outdoors. These
covers are simple-to-use and protect the input terminal panel. The cover installs over the
existing input cup, providing a sealed gland-fitting entrance to further protect the input
panel against the elements. The cover is available in black and white and can be painted.
How are the EVID full range models tested for weather
resistance?
All EVID full range loudspeakers feature weather resistance design criteria which allow
them to pass MilSpec810 and IEC529 specifications. These specifications provide tests
to determine outdoor capability in severe climates. Five separate test sessions are
