To ensure that the speeches are heard perfectly, "line array" sound system will be used. These would ensure that every word spoken from the stage is delivered in perfectly audible form to those attending the rally, he added.

"The Line Array System ensures that even the last person standing or sitting on the ground gets to hear as good a voice as the first one. The sound system will use four-way speakers," he said.
