1 INTRODUCTION

Venue Presentation

The Macon Centreplex is a multi-purpose arena and in Macon, Georgia, United States. It was home to the Macon Whoopee (ECHL), Macon Whoopee (CHL) and Macon Trax ice hockey teams and also the Macon Knights arena football team until 2006. It is home to the Macon Mayhem, a minor-league hockey team in the Southern Professional Hockey League. Seating 7,182 for hockey and arena football and up to 9,252 for concerts.

Since no CAD was available, this room model was measured by L-Acoustics personnel onsite. As such, this venue model must be considered a “draft” and all measurements should be double checked for accuracy by integrator and end user.

Prerequisites

This document exposes a Sound System Design concept as well as its corresponding equipment schedule and deployment.

The L-Acoustics proposal is based on a “Full System Approach”. The design solution includes speakers, rigging, amplification, and DSP for the system. This results in a highly predictive, standard system with control and monitoring that satisfies the performance requirements of the venue.

Network Architecture & Remote Control

The design of complex systems is made possible by the integration of the L-NET Ethernet-based network. Thanks to its high-speed data transfer protocol of 1Gbit/s, up to 253 units can be controlled and monitored in real-time by LA Network Manager software. Multiple network topologies such as daisychain, star, and hybrid are quickly and easily configurable for full flexibility in the required system architecture.

The PC running LA NETWORK MANAGER and the units are connected to each other by using industry standard CAT5e U/FTP cables fitted with RJ45 connectors. Optimized for tablet PC use, LA Network Manager relies on a purely graphical approach and allows placing units and groups in a workspace in a way that reflects their location in the field. It is designed to quickly take the user through the workflow steps of Setup, Tuning, and Live by implementing the tools required for each task into their dedicated page. An advanced network engine allows automatic discovery of connected units. Multiple-group assignation capability, comprehensive real-time monitoring of events with the log file, as well as numerous productivity tools complete the characteristics of a remarkably practical and application- oriented network management software.

As a certified member of the Crestron and Extron partner programs, L-Acoustics provides software modules allowing control integration into their automation systems, for the convenience of ultimate technology lifestyle in cultural and event centers, universities, houses of worship, sports facilities...

L-DRIVE

The latest L-DRIVE protection system carries out an advanced analysis of signal level. When transducers operate in the non-linear domain, either at high excursion, high temperature or high voltage, L-DRIVE acts as a smart power regulator to extend the component durability while maintaining the highest dynamic range. The L-DRIVE circuit has been designed to preserve the sonic transparency of the system.

Fallback Mode – Fail Safety

This possibility prevents sound cut in case of digital signal failure (no clock, loss of lock, invalid audio [validity bit], CRC error, bipolar encoding error, data slip), by allowing the amplified controller to automatically switch from AES/EBU to ANALOG inputs. After the digital signal has returned to “normal” state, reverting to the AES/EBU input mode is not automatic and must be done manually by the user (by using LA NETWORK MANAGER software or third party control system, one click is sufficient for all concerned amplified controllers).

11 www.l-acoustics.com


Load Checker

LA Network Manager Load Checker collects data about the connected load's impedance to estimate matching between connected enclosures and the selected preset, as well as the number of loudspeaker sections connected per output, taking into account cable characteristics and ambient temperature. Color coded results help identify potential preset/enclosure mismatches, cable issues or loudspeaker failures.

Cable Length

L-Acoustics uses proprietary tools to compute the influence of cable length for each specific Amplified Controller output channel. Compensation takes into account: cable length, cable section gauge, speakers impedance at channel ouput. This is compensated using specific filtering during the calibration process.

Integration team can anticipate cable length limit using an online tool available at:

http://www.l-acoustics.com/installation-tools-137.html

L-Acoustics engineering team will provide support to RAH Audio team for best cabling strategies.

Settings protection

In order to ensure the integrity of a fire alarm system, access to the amplified controller’s parameters has to be restricted. These parameters can be protected independently from:

• LA Network Manager and amplified controller front panel access

• third-party control system application using a specifically determined access policy Settings Protection is

based on three levels of users.

When Settings Protection is enabled by the Administrator:

Only the Administrator can (Master Password) The Advanced User can (PIN code)

The General User can

• load non-authorized Session files

7 ACOUSTIC SIMULATION

Soundvision Software

www.l-acoustics.com


The proposed project below was modelled after drawings we received using L-Acoustics acoustic prediction software, Soundvision. Room acoustics is not considered in prediction and plots provided have been presented to show direct field coverage.

Acoustical Simulation Program Developed for sound designers, Soundvision is dedicated to the acoustical and mechanical simulation of L-Acoustics systems (WST line arrays and coaxial point source technologies). Benefitting from L-Acoustics long term experience in the modelling of acoustic sound sources, Soundvision is the first 3D sound design program capable of operating in real time.

Real time calculation of SPL and visualization of system coverage Soundvision allows the calculation of sound pressure level (SPL) coverage, SPL mapping and delay coverage (or mapping) for the complex sound systems and venue configurations. Either horizontal (plan) or vertical (cut) views can be selected to enter room coordinates or to define loudspeaker placement/aiming. Impact coverage, SPL mapping or delay is then based on direct sound calculation over defined audience geometry.

8 TECHNOLOGY OVERVIEW

Sound sources

Ever since its creation, L-Acoustics philosophy is to offer a clear and streamlined product line with high quality purpose-built products. Our full-range loudspeaker systems are organized in three sound source families addressing distinct coverage and throw needs. These systems can be completed with our range of sub-low sources.

Point source The most coherent in near-field applications

• Short throw (up to 15 m) • Smooth directivity with coverage angle(s) depending on enclosure

P Series / X Series (108P, 112P, 5XT, X8, X12, X15-HiQ) Deployed as non-arrayable elements

Constant curvature line source Intuitive deployment as slices of coverage

• Medium throw (15m to 35m) • Sharp directivity with incremental coverage

ARCS Systems (ARCS II, ARCS WIDE, ARCS FOCUS) Deployed as horizontal or vertical arrays with fixed inter-element angle Variable curvature line source

Precise adaptation to audience geometry

• Long throw (35m and above)

• Sharp directivity with adjustable coverage

K Systems (KIVA-II, KARA, K2, K1) Deployed as vertical arrays with variable inter-element angles Omni/cardio subwoofers Augmented sub-low resources

• Increased LF contour and extended LF limit • Rear SPL rejection if needed

SB Series (SB15m, SB18i, SB18m, SB28, K1-SB, KS28) Deployed as single elements or arrays



Technologies

In its thirty years of research and development, L-Acoustics engineers have developed a number of major loudspeaker technologies. The followings are examples in the field of electro-acoustic.

Coaxial In 1989, L-Acoustics introduced the first coaxial loudspeaker enclosure for professional sound reinforcement, bringing studio quality to near-field applications for the first time. Since then, coaxial technology has been implemented in all L-Acoustics point sources and constitutes the heart of the P Series and X Series.

Ellipsoid waveguide The ellipsoid waveguide made its debut in 2015 in the X12 and X15 HiQ coaxial enclosures. By providing a distinct coverage angle for both vertical and horizontal dimensions, it extends the versatility of the enclosures, as well as improving control over the reverberant field.

DOSC waveguide With the proprietary DOSC waveguide, the V-DOSC system was the first line array to operate coherently across

the whole audible frequency range. Since 1993, this major technological innovation is at the heart of every WST line source element, with specifically tailored DOSC waveguides for constant curvature arrays (ARCS systems) or variable curvature arrays (K systems).

L-Fins Introduced in 2008 with the KI system, the L-Fin waveguide marked the transition from the “V” transducer layout of legacy V-DOSC and dV-DOSC systems to the “K” transducer layout.

L-Fins significantly improve the precision and smoothness of the directivity pattern in the horizontal plane. In addition to K1, L-Fins are featured in Kara and ARCS WiFo.

Panflex Panflex was introduced for the K2 system in 2014. Combining L-Fins and DSP, it offers the possibility to change

the horizontal directivity pattern from wide to narrow, from symmetric to asymmetric. With Panflex, a variable curvature line source can now match the complex shape of any audience geometry, both in the vertical and horizontal planes, further minimizing noise pollution.

Laminar venting All current L-Acoustics loudspeaker enclosures with low-range capacities feature laminar vents which provide high

SPL while eliminating turbulence noise. This technology was implemented for the first time in 2007 in the SB28 subwoofer and has been included in K1, K1-SB, K2, SB15m, SB18(i/m), and the X Series.

LA4X is a “green” amplified controller that relies on a universal the dynamic and thermal capacity of each individual transducer. With switch mode power supply suitable for mains from 90V to 265V. a complete preset library and the possibility of creating additional The SMPS features a Power Factor Correction (PFC) which user presets, the engineer is offered access to all the L-ACOUSTICS maximizes the amplifier efficiency and takes advantage of nearly loudspeaker system configurations at their fingertips. 100% of the electrical power available with a very high tolerance to unstable mains. The PFC allows the LA4X to deliver as much power from a 10A line as from a 16A line on a conventional amp. uSer interfAce

This represents a reduction of the electrical power requirements (cable gauge, power conditioning, etc…) for substantial savings. The The front panel user interface features extremely fast access to Class D amplification circuits ensure the LA4X energy-efficiency for editing the 4 input and 4 output settings. The encoder wheel gives minimal heat dissipation. LA4X delivers 4 x 1000W RMS power at instant access to the user menus and the 2 x 24 character LCD 8 Ω or 4 Ω with record hold times. Besides the high raw RMS power screen offers real time visualization of the system parameters. rating at 8 Ω, the ability to deliver energy (power x hold time) yields Command access includes routing, mute, gain, preset selection, plus the best performance from loudspeaker systems, especially in LF delay and polarity settings.

The LA4X inputs are available in analogue or digital format. Four cascaded 24-bit A/D converters at the front-end yield a groundbreaking encoding dynamic of 130 dB. AES/EBU digital inputs operate with sample rate converters from 44.1 kHz to 192 kHz. Automatic fallback functions make the creation of redundant audio paths possible. Proprietary algorithms are processed in a 32-bit floating point DSP engine at a 96 kHz sampling rate. A dedicated engineering approach combining IIR and FIR filters generates perfectly linearized phase curves and significantly improved impulse responses for an even, more natural, transparent, and realistic sound experience. Room tuning and system EQ can be achieved without external processing. The amplified controller can act both as an EQ station and a delay line, offering on each channel up to 1000 ms of delay, a pool of 8 IIR and 3 FIR filters and the air absorption compensation filter. The L-DRIVE protection system carries out a dual analysis of signal level in real-time and RMS. When transducers operate in the nonlinear domain, either at high excursion or high temperature, L-DRIVE acts as an intelligent power regulator to preserve the durability of
