As AV technology continues to advance rapidly, audio video system integrators have more options than ever before when it comes to designing and implementing audiovisual solutions for their clients. While this increased flexibility provides many benefits, it also means there are more factors to consider in order to ensure an AV solution meets a client's specific needs and budget. This article will outline some of the key elements that audio video system integrators should evaluate when developing AV design solutions.
Audio/Video Equipment Selection
The first step is choosing the appropriate audio and video equipment for a project. This involves understanding the client's requirements in terms of:
Projected image size and quality needed
Number of screens/projectors required
Loudspeaker/amplifier power for room size
Video source devices like Blu-ray players or streaming devices
Audio connectivity options like HDMI, 3.5mm, wireless, etc.
AV system integrators need to carefully evaluate these factors and select equipment that offers the ideal balance of performance, features and value for a client's specific application. Other considerations include equipment placement, cable runs and compatibility between components from different manufacturers.Taking the time up front to specify the right audiovisual gear will help ensure a seamless installation experience down the road.
Control System Integration
Modern AV designs almost always require some type of centralized control system to switch inputs, adjust volumes and power equipment on/off. While basic single-room systems may only need simple IR or RF remotes, larger multifunction installations demand more robust centralized control.
When deciding on a control solution, integrators should think about:
Level of control complexity needed (basic vs highly integrated)
Type of user interface preferred (touchpanel, apps, buttons)
Brand compatibility if mixing manufacturers' equipment
Scalability to expand system over time
Programming expertise required for custom integration
Choosing a control platform with an open architecture and customizable programming allows for flexible expansion as needs change.
Mounting and Infrastructure
Mounting and infrastructure refer to the physical structures and wiring used to securely install and connect audiovisual equipment. Common considerations here include:
Determining mounting locations for displays, projectors, speakers and other hardware
Securing devices to walls, ceilings or stands safely and aesthetically
Managing and routing cabling for signal, power and control through structures
Accounting for current and future cable runs during planning and install
Ensuring adequate infrastructure like power, ventilation and physical space
Proper planning at this stage prevents on-site headaches and future upgrade issues down the road. Utilizing structured cabling solutions and future-proof pathways allows maximum flexibility.
Acoustical Treatment
For audio systems, acoustical considerations are essential – especially in challenged spaces. Surfaces that absorb versus reflect sound impact room acoustics significantly.
Some key factors for AV designers include:
Measuring room reverb time to determine absorption needs
Choosing absorption materials based on frequency and coverage areas
Placing panels methodically on first reflections and problem zones
Balancing acoustical adjustments with aesthetic/budget factors
Consider testing with simulation software prior to install
Addressing noises, echoes and reverberation in advance results in clearer, more natural sounding playback.
System Configuration and Calibration
After equipment is installed, the next critical phase is properly configuring and calibrating the entire audiovisual system to work seamlessly as an integrated solution. Key configuration tasks involve:
Labelling all connected devices for easy control
Setting resolution, aspect ratio and other parameters correctly
Configuring network/wireless for control and streaming
Programming control system interfaces and macros
Setting up audio/video preprocessing like volume controls
Calibration then fine-tunes the system performance through:
Display calibration for color, brightness and geometry
Speaker level, delay and equalization adjustments
Tuning audio processing like bass management
Configuring room correction/EQ software if utilized
Thorough configuration and calibration ensures a top quality experience for end users.
Testing, Documentation and Support
Before client sign-off and turnover, audio video system integrators should conduct rigorous testing to verify system functionality, responsiveness and reliability under all expected use cases. They should also provide:
Complete system maps, manuals and operating guides
On-site training for client users and operators
Remote and/or on-call technical support
Regular system checkups and maintenance plans
Spare parts inventory to handle repairs promptly
Comprehensive documentation and support offers peace of mind and protects the investment long after initial installation.
Overall AV Integration is an Art and a Science
As this overview outlines, developing AV design solutions that meet stakeholder needs is part art and part science. The most successful integration firms have extensive expertise with the technical specifications of audiovisual equipment as well as an intuitive understanding of a client’s vision and usage environment. By carefully weighing factors like equipment, control, infrastructure, acoustics, configuration and support, system designers can craft intuitive, high performing solutions clients are proud to showcase for years to come. Solid execution of these key elements differentiates an average installer from an industry leader in audio video system integration.
