4. With the green circuit board on the
right, place the attenuation module
in the pocket provided for it on the
left with the lead wires from the
module pointing toward you.
5. Secure the EVA-AM mounting ears
to the four input panel bosses
with the four #10 screws provided.
Carefully tighten the screws evenly
in an X-cross pattern to avoid
warping the plastic input panel.

7. Reconnect the 10-pin connector from the crossover and reinstall the input panel.
EVA-AM must be on the enclosure center-line to maintain horizontal center of gravity.
Do not install input panel backwards!

8. Apply the new label (supplied) over the input connectors.

9. Connect one end of the blue wire (supplied) to the terminal marked “Select”. Set the
attenuation level for the module by connecting the other end of this wire to either the
-3 dB, -6 dB or -9 dB terminal, as determined by EVADA.
10. Connect the input lines to the module at the (+) and (-) terminals the same way you
would a standard non-attenuated EVA loudspeaker. The EVA-AM attenuates ONLY
the loudspeaker in which it is installed.
Important Note: Once an EVA-AM is installed, an attenuation level MUST be selected. (See step 9.)
If this wire is not connected, the entire loudspeaker in which the module is installed
WILL NOT FUNCTION!

Tighten all unused connector screws to
prevent rattles!
