The Business Audio “Business” Business audio or “backgro und music” has come a long way since the days of Muza k and “elevator music” systems of the 50’s – 80’s. Countle ss retail establishments such as clothing stores restaurants, department stores and even “d rug stores” are spending mone y on better quality audio. Many cont[...]

We have to approach each desig n analytically. The first step is to determine what the custome r wants and expect s. The questions you ask up front he lp you decide what kin d of sound system to propose. As you start thinking about the desig n, you need to translate the client's requirements into terms of coverage, adequate sound levels and ba[...]

EV Business Audio Product Guide EVID Surface Mount Speaker Systems The “ID” in EVID is for I nnovative D esign of high quality foreground /background speaker systems. EVID is not just another box, or trapezoidal system, EVID is different. It’s unique design concept combines style with acoustics for several be nefits. Innovation in Design EVID[...]

The real solution to the problem requires that directionality must exist for the criti cal mid frequencies as well as the uppe r end of the spectrum. For this to happen a new approa ch is needed. An effective answer to this problem is the EVID C8.2HC The EVID C8.2HC is designed to provid e directi onality through the critical voice spectrum by empl[...]

preference? Getting this kind of informat ion at the beginning will help to avoid confusion and delays at the installation stage. Just as important as the human factors are the c onst ruction details of the site. How are the walls and ceilings constructed? What kind s of mount ing surfaces will be encountered? Is the drop ceiling a lay-in type, or [...]

Step 4 – Assemble the Equipment List At this point an equipment list needs to be assemb led and the hard ware portion of the job can be estimated. Also labor estimates can be done as well after a site inspection has been condu cted and physical layouts to scale have been con structed. Upon completion of a thorough site survey, the system may be s[...]

Standardizing for Profitability One of the best strategies that we can recomm end for su ccess in contracting is to standardize your operations wherever possible. Settle on a fe w basi c system desig ns that can be modified to cover a wide variety of circumstances a nd then educate your sales staff about them. Develop standard pricing cal culations[...]

constraints tend to favor sacrifici ng density, so the optimum center-to-cent er configuration is, in practice, the least common of the three. Ceiling Speaker Coverage The main objectives in deciding about the placement pattern an d density of loudspeakers in a distributed system are covering the a rea effectively, providing sound that is audible a[...]

Converting Coverage Spec s to A Layout How do you convert polar coverage to listeni ng-plane coverage as y ou desi gn sound systems? There are two ways. One is to use the EV ceiling speaker layout program that does the conversion for you. For more elaborate analysis you can use EASE. Ease can determine intelligibility and map the SPL output of your[...]

The EVID C4.2 is just such a 4” speaker. The effect of the C4.2’s wider dispersio n is indicated in the figure at the right. In applications where reverbera tion is not an issue, the C4.2 (shown with coverage pattern “A”) offers greater overlap an d, thus, more uniform coverage than an 8-inch unit (coverage pattern “B”). When sp ecifyin[...]

such as speaker pl acement, boundary loading (are speakers placed close to a wall or in a corner?), size of the room, coupling of m ultiple speakers/subwoofers, reverberance of the roo m, the type of music, the type of ac tivity and the expectations of t he listeners all come into play.

Power amplifiers and the DCS 400 controller are conn ected to another independent RS-485 port, which allows direct mana gement of up to 64 power amplifiers and 8 DCS 401. Connecting a PC is established via seri al RS-232 port on the rear panel of the DPM 4000. It is not necessary for the PC to be permanent ly connected to the DPM 4000. An additiona[...]

The DCS 400 Expa nsion Chas sis The DCS 400 expansion chassis uses essentially the same techni ques for installing the cards/modules as is used when installing cards in the DPM 4000. The left-most card (as viewed from the rear) is always either a DCS 401R controller card, or a DCS 405R extension card. Th e DCS 405R cards are u sed to expand from on[...]
