4 Orientation INTRODUCTION The AccessEZ ™ series of demonstration system modules provides a plug-in solution for car audio, hi-fi, and video switching systems in retail display envir onments. This second generation of the highly capable, indus- try-acclaimed Access ™ System modules offers many new featur es and benefits: • AccessEZ offers a c[...]

5 What is the Access ™ System? The Access ™ System consists of a variety of intelligent switching modules. These modules communicate with each other via the “system bus,” allowing you to construct the exact demonstration system configuration you desire fr om the sources, pr ocessors/equalizers, amplifiers, speakers, and subwoofers in your d[...]

6 Bypass A way to hear a system without a particular in-line component (EQ, Cr ossover , Amplifier , etc.). For example, when you wish to hear a system without the pr ocessor , the system can route the signal past the pr ocessor group and dir ectly to the amplifiers. In this expample, Position #4 on the last module in the Processor Pr oduct Group i[...]

15 BEGIN INST ALLA TION 1. Preparation Follow these steps carefully: A. Review the design of the demonstration ar ea. • Make sure the display fixtur e is corr ect for your installation. • Look at the supplied system wiring diagram, or choose one fr om this manual to serve as an example. Examples are in Appendix A: Sample Systems. • Gather the[...]

16 Sources, EQs and Amplifiers Speakers Note that the front amps and speakers have matching group numbers as do the rear amps and speakers. As a rule, related amps and speakers have match- ing group numbers; this determines how the 902 Control Panel, if used, handles V olume Compensation of the products in these Gr oups. Figure 15 shows how the 902[...]

17 C. Set the Address Switches. Some Group settings ar e made at the factory , and cannot be changed later . Figure 16 shows the first switch module (Model 910D) in the first Product Gr oup (head units). It has a default address of Gr oup #0 (set at the factory) and the Module ID is set to #00 (this lets the system know this module is connected to [...]

18 “B” should be set to “OFF” unless you wish to BYP ASS the pr oduct group associated with the module. The bypass module is always the last module in the product gr oup to be bypassed (only the bypass module should have the “B” switch turned ON). A pr oduct group will be bypassed when all products in that gr oup are unselected. Bypass [...]

19 3. Installing the System Hardware A. Designate the Switching Module Locations. Each switching module controls either 4 or 8 components. Follow your system plan drawing to determine the location of the switching modules in the display fixture. If you ar e using factory provided bus cables, you may wish to connect all the modules that share the sy[...]

20 4. Installing the Bus Cables Pre-assembled bus cables or the raw materials to make the necessary bus cables on the job site wer e included with your system purchase. Pr e-assembled bus cables have connectors every two feet (RCA patch cords ar e available in lengths from thr ee to twenty feet). If you plan to make your bus cables on the job site,[...]

23 T o demonstrate amplifiers without inline products such as Processors or EQs, it is necessary to bypass the Pr ocessor/EQ Product Gr oup at low-level. Figure 28 shows how to r oute the signal from the input of the 958 past the display pr oduct connec- tions and on to the Amplifier Product Gr oup. The fourth posi- tion on the last module is reser[...]

If 915X modules are part of your system, wir e them in the same manner as the 910 modules. Connect the pre-made power cab[...]

25 Here ar e the three dif ferent Power Modes: • Power Conserve allows only one component from each electronic gr oup to be ON at any given time. New selections have a turn-on delay of either 3/4 seconds or 3 seconds, depending on how the T switch is set on each main module. • Smart Power Mode allows up to three components in each electr onic p[...]

27 • If your system is all new , proceed to step 4. If some or all of your system is older (softwar e version earlier than 3.2) the SST jumper switch on the 980 module must be in the F AST pin position (Figure 33). The factory position for the jumper is “NORM.” The SST jumper on the Model 980EZ must be cut and re-solder ed to change its posit[...]

28 INST ALLING A CONTROL P ANEL Skip this step if you do not have a 902, 903 or 906 Control Panel, or if the display is pr e-assembled. If you have a 902 or 903 Control Panel, it is accompanied by a separate User ’s Guide which you should locate for future r eference. 1. Cut an opening for the Control Panel if you wish to flush mount it in your d[...]

29 • Plug the calibration micr ophone into the Microphone jack located on the rear of the 902, using the extension cable provided, if necessary . • If your system includes a Model 990 Remote Infrared Receiver , mount the 990 to the ceiling in the display area and connect the 990 to the header on the r ear of the 902 labeled “Aux IR.” Note: [...]

31 980 System Module Accessories. In systems without a control panel, it is usually desirable to add “outboard” switches for r emote operation of certain 980 system management tools. Remote Power Switch. If your system does not include a Control Panel, you may want to turn the system on and off using a r emote key switch or toggle switch. • U[...]

32 Remote System Reset There is a “System Reset” button on the 980 that enables the user to r eset the system in the unlikely event that the system “hangs up.” Pressing this button will r e-boot the entire system. Having a Remote Reset switch is a good idea in any system since the 980 is usually buried inside the display and would not be re[...]

33 • If the numeric displays begin flashing at any time during the module scan, two or mor e modules have the same address. Duplicate addresses ar e disallowed because the control panel is unable to tell two identically addressed modules apart. Note the last group number displayed in the Product Gr oup windows and the module number displayed in t[...]

34 3. Select a speaker position using the test PSB, then move the PSB to the same module location on the opposite side of the speaker section of the display . • The PSB lights up as soon as you plug it in, showing both left and right speaker positions are selected. 4. Attach the test PSB to a second speaker in a group, pr ess the PSB and hold the[...]

35 • Connect the gr ound lead to the GND terminal. • Connect the memory lead to the BA T terminal. • Connect the ignition lead to the IGN terminal. • Plug an FM antenna cable fr om the FM Distribution System into the unit’s female antenna jack. • Install the unit in your fixtur e. B. Connect a processor ’s audio inputs and outputs to [...]

36 • Connect the left speaker to one of the 2 position terminal blocks on the Left 932 and the right speaker to the corr esponding position on the Right 932. W ire the positive lead to (+) and the negative speaker lead to (–). • Connect the two-pin plug of the PSB’s cable, if PSBs are used, to the small 2 pin headers on the 932 cir cuit boa[...]

37 3. Connect the Battery If a battery is to be used as part of your DC power system, install it in the system between the power supply and the DC distribution system you installed earlier . A. Locate your battery within 10 feet (3 meters) of the power supply , preferably an Audio Authority Model 277 Hybrid ™ Power Sour ce. W ARNING: Never allow [...]
