If the loudspeaker has two connectors for the same mode of operation, they are wired in parallel
so you can “daisy chain” multiple loudspeakers together to a single amplifier channel.

L o u d s p e a k e r C a b l e
To minimize power losses and provide a sufficient damping factor (DF) for low frequency drivers,
use loudspeaker cable with conductor sizes per the following chart. For cable lengths over 200 feet
at 8 ohms and over 100 feet at 4 ohms, the conductor sizes needed for an adequate damping factor
are rarely practical for physical and cost reasons. For these situations, 10 AWG / 25 metric gauge are
recommended as the most practical sizes.

Many EAW loudspeakers are designed to be used with an electronic signal processor such as
EAW’s MX Series Close Coupled™ Processors.: the analog MX250 or digital MX8700 and
MX8750. Contact EAW’s Application Support Group to determine the correct processor and
settings for your loudspeaker.
