Part Two

• Domain A – – Sell AV Solutions– Conduct Vendor Selection Process– Provide AV Solutions

• Domain B – Operate AV Solutions• Domain D – Troubleshoot AV Solutions


Sell AV Solutions

• Best Practice– Show courtesy to the client, other trades, and coworkers.

Defer jobsite questions to the project manager.– Everyone who comes into contact with clients and other

trades in the course of their work must consider themselves a salesperson for their company.

– Simple courtesy can pay off in cooperation between trades, and certainly can make a difference in the attitude of the client towards the workmanship and quality of service for which they are paying. This can mean referrals and repeat business.

Ch 25


Sell AV Solutions

• Effective Listening• The Decision Maker• Customer Service

• A customer’s satisfaction means continued business and possible referrals. Listening to the clients' needs, working with the clients to satisfy those needs, and updating the clients on the status of their solution require highly developed customer service skills.

Conduct Vendor Selection Process

• Best Practices– When the equipment is delivered,

make sure the equipment is properly received and unpacked.

– Confirm that it meets project specifications.

– Test the equipment before it is delivered to the project site.

– Collect all the accompanying documentation – warranties, instruction and owners manuals, etc. Courtesy of Crimson Tech

Domain A - Provide AV Solution

• Install elements– Tools– Projector Orientation– Loudspeaker Systems– Cable Considerations– Mounting – Power

• Control Systems– Controlled Functions– User Interface– Dashboard for Controls

• Commission system– Punch-list

• Demonstrate and Test Equipment

• Create Documentation • Training

Ch 19


Install Elements

• Create a tools checklist• Best Practice

– Each setup will require different equipment. Note the equipment needed for each job, and keep it in the job file. When you are picking up the equipment and assembling it for installation, a quick glance at the checklist will let you know everything is ready to go. If the installation is temporary, use the checklist during the strike to account for all the equipment. Ch 19 – Pg 375


Install Elements

• Projector Orientation– Front-table– Front-ceiling– Rear-table– Rear-ceiling

• Best Practice– Check the structure for vibrations by resting your

hand on the beam or bar-joists. Sometimes the HVAC unit is mounted on the roof above, creating vibrations which will cause the image to appear unfocused.

Ch 19 – Pg 399


Install Elements

• Loudspeakers• Point-Source and Distributed

Systems– Point Source- deliver very loud

sound coming from one location– Distributed Systems- loudspeakers

strategically suspended overhead or installed into the ceiling


Install Elements• Cable Installation

– Raceways

• Ducts – typically rectangular – Cable tray

– Trough – aka wireway

• Conduit – tubular, solid and circular – PVC (plastic) Conduit

o Electrical Nonmetallic Tubing (ENT)

o Inner Duct o Rigid Nonmetallic Tubing

– Metal Conduito Electrical Metallic Tubing (EMT

or thin wall) o Flexible Metal Conduit (Flex)o Intermediate Metal Conduit

(IMC) o Rigid Metal Conduit (Rigid)

Ch 19 – Pg 389


Install Elements

• Cable Installation– Permissible Areas– The certain maximum amount of space that cables should occupy

inside the conduit.• 1 Cable = 53% of conduit area

– If you are running only one cable in a conduit, that cable may occupy up to 53% of the conduit's inside area.

• 2 Cables = 31% of conduit area– If you are going to run 2 cables inside a conduit, these 2 cables may

occupy up to 31% of the conduit's inside area. • 3+ Cables = 40% of conduit area

– If you are going to run three or more cables inside a conduit, the cables may occupy up to 40% of the conduit's inside area.


Install Elements• Cable Installation

– Signal Separation– Refers to providing physical distance among cables carrying

various signal levels• When grouping cables together in a bundle, all cables should be

intended for only one signal type. Generally, group cables according to these guidelines: – Microphone– Line and communication– Control and data– Loudspeaker– AC technical power– Video– RF

Best PracticeConsider color coding cable to help maintain separation when you are bundling cables. Color-coding requires stocking more cable, but it can speed things up with a big bundle. You should always label cables as well.

Ch 19 – Pg 386


Install Elements• Mounting Safety Tips• Safety first!

– It is important to define the specific parts that you will be using and to use the parts that are defined. Include the following information:1) Review the size and weight of what you will be mounting, along

with all the parts and their weights. 2) Verify the location of the mounting. 3) Look at the structure to which you will be mounting, and assess

any potential problems. 4) Look at the structural designs of the room or building to ensure

safety. 5) Review all manufacturer guidelines and drawings.

– A structural engineer should review all mounting plans and advise on any difficult situations that you may encounter. When in doubt, always ask for help. If you modify another contractor’s work, you become responsible.


Install Elements

• Mounting Safety Tips• Load Weight!

– Best Practice to multiply the published design weight by five. If a loudspeaker with mounting hardware weighs 100 lb (45kg), you should use mounting criteria that will handle 500 lb (225kg). Five is the safety factor. The term safety factor is sometimes referred to as design factor, load factor, or safety ratio.

• Remember, the weakest point in the assembly is as strong as the entire assembly can be.

• Mounting Malfunction – Shear – Tensile – Pull-out

Ch 19 – Pg 395


Install Elements

• Mounting– Mounting is the practice of suspending or attaching

components to the structure of a building.– Fasteners

• Best Practice• It is best to get your fasteners from a reputable organization. • A local hardware store may not have grade 5 or 8 hardware in

stock

• Floor Mounting• Overhead Mounting• Wall Mounting

Ch 19 – Pg 395


Install Elements

• Where does Power Come From?– Power generation station– High voltage transmission lines– Electric substations– Local transformer


Install Elements

• Power on site– Service Drop– Service entrance– Electrical Service-Equipment

Entrance Panel– Main Distribution Panel– Feeders– Subpanels– Individual branch circuits– Wall outlets– Directly wired equipment

Ch 9 – Pg 166

Demonstrate and Test Equipment



Create Documentation

• Create documentation (user manuals, maintenance reports, etc.)

• Best Practices– Arrange equipment manuals in alphabetical

order and groups by function (an example would be all display types).

– Leave a copy of the software documentation with the equipment rack, the project manager and the client/end user.

Ch 21 – Pg 443 - 446


Create Documentation

• Best Practices– Save all computer files associated with equipment,

especially if the files contain records of the system settings.

• It is most professional to arrange customer equipment manuals in a binder?– Alphabetically and grouped by function.– By purchase date. – Numerically by part number. – By cost.







Create Documentation • Training

practices. Date Time Initials Work performed

020308 10A AJB Checked in with the on-site client before testing 1 year maintenance on Ballroom A. Tested for proper levels throughout the audio system using a meter and signal generator. All systems checked out OK. Noticed that fan in audio system rack was not operating. Recommended to client to call repair (800.123.4567) and speak with Tom for replacement. Before leaving at 3p, secured all rooms and checked out with client.

060308 8p AJB EMERGENCY CALL TODAY. Digital Signal Processor failed. Had to referernce user’s manual to get part number to replace the failed unit. Happen to have a spare device in the truck so replaced it. Reported to client status of problem. Will return to replace when part comes in. Left at 2a.

060508 8a JAR Normal tech not available today (AJB). Replaced DSP after notifying client. Had to get key from security guy to get access. Lucky break – DSP data configuration file was on USB backup pen drive! AJB left directions on how to upload Crosspoints on DSP. Verified that DSP was operating within normal parameters. No problems. Checked-out with client at Noon. Client said he was impressed with our work and has a friend who wants our company to do a retrofit install – told him I’d have sales dept. contact him.
