system was used at the recent
Morgan Hill Mushroom Mardi Gras.
Morgan Hill, CA (July 8, 2009)–Morgan Hill, CA-based live audio specialist, 4 dB Sound, recently completed providing audio reinforcement for the main stage at the 30th annual Morgan Hill Mushroom Mardi Gras. An ISP Technologies Tripower reference concert series speaker system, configured in 4-way mode, handled the house speaker duties for upwards of 3,000 people at the Morgan Hill amphitheater.
The ISP system was in place at the festival providing sound-reinforcement over the two-day run. The ISP Tripower reference concert series system includes an 18-inch, powered subwoofer and the Tripower Reference, which is a 3-way, powered top box. The Tripower Reference is in two cabinets, where the lower cabinet includes the three-way amplifier module, all signal processing and dual high output 12-inch woofers; meanwhile, the top cabinet is a mid-high horn pack that includes a large format 3-inch compression driver to cover the midrange frequencies and a neo magnet polyester diaphragm 1.75 inch high frequency driver to cover the high frequency portion of the spectrum. The Mid-High Horn pack connects to the active electronics in the lower cabinet via a 4 conductor NL4 speakon interconnecting cable.
“Portability, ease of set up, high-impact and economics are our biggest concerns,” said Tony Tissot of 4 dB Sound. “The ISP system worked perfectly at this venue, covering a crowd that was much larger than expected. This system is normally used to cover 300 to 800 indoors and 300 to 600 outdoors, but the shape of the amphitheater stage with its curved back “shell” and the tiered audience bowl makes it an ideal venue. There are no rigging points and set up time is minimal, so flying isn’t an economical option. The 4-way system is complete with amplification and processing, so setup times are quick and painless. We ran the system under 100 dBA at FOH – about 60 feet back from the stage. It’s very loud up front, but comfortable for families in the back–exactly what the organizers wanted.”
