Extending the low frequency response of your active monitoring
system. This works for mono, stereo, and 5.1. Instead of connecting your
audio source directly to your active monitors, connect the source to the five
monitor channel inputs on the 20/20 S250, and feed the pass-throughs
from those inputs to your monitors. The five monitor channels are marked
on the 20/20 S250 amplifier panel for convenience during wiring, but all of
the five inputs are identical and are summed equally within the subwoofer.
If you are using any speakers other than Event Direct Field Monitors, start
with the Polarity Invert switch in the out (off) position, and set the Phase
Delay control to 0
°
. If you are using Event Direct Field Monitors, we
recommend using the settings found in the table on page 6.
Signals coming into the subwoofer via the five monitor inputs are muted
with the Monitor Disable button. This mutes the Subwoofer if there’s no
LFE input.

• Putting it all together. The 20/20 S250 System Subwoofer is in full
form in a 5.1 surround system where all five monitor inputs are used along
with the LFE input. If you are using any speakers other than Event Direct
Field Monitors, start with the Polarity Invert switch in the out (off) 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 Event Direct Field Monitors, we
recommend the settings found in the table on Page 6.
The Subwoofer’s Phase Delay control is also used to maintain good
crossover alignment when the Subwoofer can’t be placed on the circle.
Notice the OFFSET column below. Refer to it when the subwoofer must sit
outside the circle.
