Rcf Goal
A "RCF goal post with 8/4 PA" refers to a portable public address (PA) system setup where RCF brand loudspeakers are mounted on an aluminum truss structure, commonly known as a "goal post." The "8/4" is a likely abbreviation describing the speaker configuration: four top-end speakers and eight subwoofers.
Breakdown of the components
RCF
- This refers to the Italian company RCF S.p.A., a major manufacturer of high-quality professional audio equipment, including speakers, amplifiers, and PA systems.
Goal post truss
- A "goal post" truss is a lighting or speaker stand setup made of modular aluminum truss sections.
- It is named for its distinctive shape, with two vertical towers and a horizontal crossbar that resembles a sports goal post.
- The truss provides a sturdy, elevated, and professional-looking mounting solution for the audio equipment.
8/4 PA system
This specifies the speaker configuration, although the order of the numbers can vary:
- 8 Subwoofers: The larger number often refers to the subwoofers (or "bass bins") placed on the ground. These are used to reproduce low-frequency audio and give the sound system power and depth.
- 4 Top-end speakers: The smaller number typically refers to the full-range or mid-high speakers (often RCF's line array modules or point-source speakers) that handle the mid-range and high frequencies. These are flown from the horizontal crossbar of the goal post truss.
Description of the full setup
A full RCF goal post with 8/4 PA system would typically consist of:
- PA speakers: A stack of eight powered RCF subwoofers (such as the RCF SUB 8006-AS) on the ground, with two four-speaker line arrays flown from either side of the goal post truss.
- The goal post truss: A complete truss structure with a height tall enough to properly suspend the top speakers over the subwoofers and above the audience. This includes the base plates, vertical sections, and the horizontal crossbar.
- Flying hardware: Mounting hardware and accessories, including fly bars and pins, for safely attaching the RCF line array modules to the truss.
- Cabling: All necessary signal cables (often XLR) and power cables (often powerCON) to connect the speakers to the mixing console.
Advantages of this setup
- Improved coverage: Elevating the top speakers allows for better sound coverage over the crowd, preventing the sound from being blocked by people in front.
- Enhanced aesthetics: The truss provides a clean, professional appearance compared to simple speaker stands or ground stacks.
- High power and clarity: RCF is known for its powerful and clear sound reproduction, and the combination of numerous subwoofers and line arrays ensures a massive and full-range sound.
- Scalability: The modular nature of both the RCF line arrays and the truss allows the system to be scaled up or down for different-sized events.
