With locations in Miami, New York, Boston and Haiti, Tabernacle of Glory’s non-denominational Christian congregation gathers annually at the Watsco Center in Coral Gables, FL on the University of Miami campus to celebrate the final four days of its yearly 40-day fast.
Throughout four days of worship, song and prayer, guest pastors from all over the world deliver sermons during two 4-hour worship services each day, while a 7-piece band playing Haitian Caribbean music keeps the packed house pumped.
In preparation for 8,000-plus congregants filling the Watsco Center this year, Tabernacle of Glory brought in Lennox Foster of Sound Media (Miami/Ft. Lauderdale) to design a system with enough headroom to keep the volume above the level of crowd noise, while maintaining the speech intelligibility for the pastors and simultaneously supplying enough low-end intensity for the music. The Powersoft X Series amplifier platform was at the heart of the system design.
“One of the characteristics of this event is that the crowd is very responsive,” Foster says, “and the sound system has to have enough dynamic headroom to surpass the crowd noise, which can get up to around 110 dB. When we were working at the event, the amps still had about 12 to 16 dB of headroom, even when the crowd was at its loudest.”
The Powersoft X Series provides loudspeaker management — including all signal processing functions — and also offers Armonía integration, which Foster employed to design the entire system. Using ArmoníaPlus, he was also able to manage the system throughout the day-long services, letting to control and calibrate the loudspeakers into zones and keeping sound at optimum levels.
Specifically, Foster employed 18 Powersoft X4 four-channel amplifiers to power 24 flown Turbosound TFS-900H loudspeakers, 18 flown TFA-600L and 16 flown TFA-600H loudspeakers, in addition to 10 TFA-600HW loudspeakers used for front fills. And, to power 24 Turbosound TFS-900L ground subs, Foster used four new Powersoft X4L amplifiers, which are able to deliver very high output voltage and output.
Additionally, the stage were driven nine units of the T Series platform launched by Powersoft at the NAMM Show earlier this year. “We chose this combination of Turbosound loudspeakers and Powersoft amplifiers because we needed to cover the whole spectrum of sound, and these are truly full-range loudspeakers,” Foster adds “It’s very ‘in your face’.
“The situation throughout Tabernacle of Glory’s 40-day fast celebration is very intense,” he continues. “There’s a lot of demand on the amplifiers to perform in this space at a very high energy level, because this event is very musically based, with a lot for low-frequencies from the subs. But at the same time the amplifiers need to be lightweight and efficient.
“All the Powersoft amps we used performed very well, and were not stressed in any way. In addition, these amps gave us a small footprint on the floor, with less power draw than other amplifiers.”
