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.
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 const.
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.

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.
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.
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).
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).
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.
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).

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.
24 7. Cut the red and black wir es to length, strip the ends and insert them into the terminal block on the 910 module labeled “DC Power Bus.” W ire red to “+” and black to “–” and tighten the scr ews securely . 8. If 915X modules are part of your system, wir e them in the same manner as the 910 modules.
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.

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.
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.
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.
30 6. Mount the control panel(s) using the four black scr ews provided. Do not overtighten the screws. T oo much torque during scr ew insertion can crack the acrylic panel cover .
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.
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.
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.
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.
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.
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.
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.
38 3. An isolator placed in-line between the head unit group and the EQ gr oup instead of or in addition to those in Step 2 may improve noise performance even further .
