Table 6: Dsp Settings For Ibox Bi-Amp Operation - Community iBOX SERIES Installation & Operation Manual

INSTALLATION
Operating in Passive or Biamp Mode
All iBOX models except the i2W8 and iLF218 may be operated in either the passive mode or the bi-
amped mode, selected by a switch located on the input panel. This selector switch comes equipped with a set
screw to eliminate the possibility of an inadvertent change of switch position. The set screw must be removed
in order to alter the position of the switch. Table X shows Community's recommended DSP settings for iBOX
loudspeakers used in bi-amp mode. Note that three-way models use the internal mid-high passive crossover in
bi-amp mode.

Recommended High-Pass Filters
When operating in either the passive or the bi-amplified mode, we strongly recommend the use of an
external, active high-pass filter to protect the cone drivers from excessive low frequency excursion. High-pass
filters will help protect the loudspeaker against damage from over excursion and will reduce low frequency wind
noise, turntable rumble, stage vibration, and other noises that result in a poorly defined and 'muddy' bass
response. Additionally, a high-pass filter will avoid using amplifier power that's wasted from attempting to
reproduce frequencies below the loudspeaker's intended operating range. Table 7 on Page 28 shows the
recommended filter settings for each iBOX model.
