RCF USA Invites Consultants and Contractors to Demonstrations at Cotton Bowl RCF USA will be hosting the RCF World Tour product demonstration Tuesday and Wednesday, May 20-21 at the Cotton Bowl in Dallas, Texas. This is the only U.S. stop, with RCF providing live sound reinforcement demonstrations of their line array and stadium series loudspeaker products. "This is a rare opportunity for consultants, contractors, and even prospective customers to be able to see and hear all of the line array solutions offered by RCF and dB Technologies in one place at one time," says RCF USA manager of installed sound Ken Voss. "If anyone is looking at the investment of a line array, or at the design of any large sports facility, this is a golden opportunity to explore these solutions." At the Cotton Bowl event, line array demonstrations will include full flown system configurations, with subwoofers, on the following products: • TTL55-A: Three-way active line array module with dual 12" low frequency woofers, 10" midrange and three 1.5" neodymium compression drivers. 3500W (RMS) tri-amplified achieving 143dB maximum SPL output.
• TTL33-A: Three-way active line array module with dual 8" low frequency woofers, 8" midrange and three 1" neodymium compression drivers. 1250W (RMS) tri-amplified achieving 134 dB maximum SPL
• HDL20-A: Two-way active line array module with dual 10" low frequency/midrange coupled with 3" compression driver. 700W (RMS) bi-amplified achieving 135dB maximum SPL
• HDL10-A: Two-way active line array module with dual 8" low frequency/midrange coupled with 2" compression driver. 700W (RMS) bi-amplified achieving 133dB maximum SPL
In addition, RCF will introduce their new HL Stadium Series passive two-way horn loaded arrays designed for long-throw stadium application. The series will feature three two-way cabinets featuring dual 12" woofers coupled with a 1.5" throat compression driver with 4" voice coil. The cabinets are designed with a 22.5-degree vertical coverage and choice of 40, 60 or 90-degree horizontal coverage. The series is rounded out with a single 18" subwoofer cabinet with same dimensions for array needs. Designed for high output with accurate voice and sound reproduction. Other products to be demonstrated at the event include:
• TTP5-A: New high powered, two-way 15" point source array engineered to deliver high fidelity output for use both in indoor and outdoor medium and large spaces. The 22.5° x 60° waveguide provides tight, accurate coverage. 1600W (RMS) bi-amplified achieving 138dB maximum SPL
• TTL11-A + TTS26-A system: The TTL11-A is an active steerable column array system composed of two modules--one for the mid-high and one for the bass frequencies--which is stacked on top of the TTS26-A dual 18" subwoofer. 8000W in the package achieving 140+ dB maximum SPL.
• P5228: Providing a representation of the RCF Acustica Series of IP55-rated weatherproof outdoor speaker cabinets, the P5228 is a dual 8" two-way cabinet that can be used individually or arrayed for larger environments, as will be demonstrated here.
• TTS56-A: This dual 21" 6800W active subwoofer presents "the highest power ever packed into a subwoofer," achieving 145dB maximum SPL. These will be demonstrated in partner with the TTL55-A and TTL33-A line arrays as a total system.
• RDNet: RDNet is RCF's proprietary protocol that makes it possible to monitor all the system components and parameters, from the input to the status of each single amplifier and transducer. Having a DSP on board of each cabinet, it is possible to address single cabinets or groups of cabinets with specific presets or modifications of parameters like gain, equalization, or delay, the company says. The RDNet protocol is based on RS-485 communication protocol, able to send and receive data on a either XLR cable or CAT5 cable.
And from dB Technologies, these DVA Series of products will be demonstrated:
• DVA-T12: 12" 3-way active line array with 12" low frequency woofer, two 6.5" midrange plus three 1" neodymium compression drivers. 1410W (RMS) achieving 136dB max SPL
• DVA-T8: 8" 3-way active line array with 8" low frequency woofer, 6.5" midrange plus two 1" neodymium compression drivers. 700W (RMS) achieving 128dB max SPL.
• DVA-S30N: Dual 18" high powered subwoofer. 3000W (RMS). Frequency response 30-150Hz. This is a sampling of the products that will be on display to be seen and heard at the Cotton Bowl on May 20-21. Demos will be held approximately every two hours throughout the two days. The Cotton Bowl is the centerpiece of the State Fair of Texas Park, located two miles east of downtown Dallas.
