Connections and Operation
The 20/20 S250 is ideally suited for monitoring the LFE channel, extending
the overall low frequency response of an active monitoring system, or
doing both simultaneously.
• LFE monitoring only. Feed the LFE signal via the LFE input
connector and set the subwoofer level with the LFE Input Sensitivity
control. If you are using speakers other than Event Direct Field
Monitors, star t with the Polarity Inver t switch in the out (of f)
position, and set the Phase Delay control to 0
°
. These controls may
need adjustment if your LFE program material must have a specific
phase relationship to the main program material. If you are using

listening position. After placing all the speakers on the diameter of a circle
in this manner, with the listening position in the center, distance-related
amplitude and time offsets will be minimal.
• The final element, positioning on the circle, is determined by your
format. In the case of a mono system, both the single monitor and
subwoofer are placed directly in front of the listening position, the monitor
at ear level, usually directly above the sub.
•
In a stereo system, the two nearfield monitors typically sit 60
°
apart, or
30
°
on either side of straight-ahead, again positioned close to ear level. If
you are using one subwoofer, place it on the circle between the two
speakers. If you have two subs, one for each channel, place them directly
under each monitor, again keeping everything on the circle.
• Finally, surround formats with front, center and rear speakers fill in
additional angles on the circle. The center channel is obviously located front
and center, with the two remaining front speakers at least 30
°
on either side
of center, or 60
°
from each other. The two rear surround monitors are often
spaced wider apart than the front speakers—sometimes as much as 120
°
.
