On Feb. 9, Sen. Barack Obama held a political rally to generate voter enthusiasm the day before the Maine Democratic Caucus. The rally, held at the Bangor Auditorium, in Bangor, ME, was filled to capacity. During his speech, Obama used a MIPRO wireless microphone system.

Bronson Audio Visual & Event Services of Bangor handled audio for the rally, tasked with running sound both inside and outside the auditorium. According to John Bronson, company president, “Inside, the building was filled to its capacity of 5600 people. To accommodate all the attendees that showed up, there was a second, outside location where Sen. Obama spoke, and that rally drew a capacity crowd estimated at another 3000 people. Turnout was nothing short of spectacular.”

As part of the sound reinforcement systems deployed that day, Bronson and his crew selected two MIPRO ACT-707HM PLL synthesized handheld transmitters used in conjunction with ACT-707D dual-channel receivers. Bronson selected the dual-channel receivers so he had a backup receiver channel for each microphone.

“Based on our experience with the MIPRO wireless mics,” Bronson said, “I knew the system would provide the clarity necessary to provide a clean signal for amplification and the direct audio feeds to the 48 channels of press mults and Internet feeds used by the media. The MIPRO ACT-707 systems provide us the flexibility to target and change frequencies quickly, and this capability is essential in this type of application, where many broadcasters and security radios arrive at the last minute. I find the ACT-707HM to be extremely reliable, very conservative on power and the performance of the cardioid condenser head provides great reach if the speaker holds the mic low.” Bronson also reports that the primary line array was located 16ft behind Sen. Obama and the off-axis rejection of the mic provided extreme gain before feedback.
