“B” should be set to “OFF” unless you wish to BYPASS the product group associated with the module. The bypass module is always the last module in the product group to be bypassed (only the bypass module should have the “B” switch turned ON). A product group will be bypassed when all products in that group are unselected. Bypass is commonly used in systems where there are both low-level and high-level output signals from head units (see Appx A, page 40 for a hookup diagram).

“M” has special functions for multi-channel amps and should be set to OFF. Call the factory for details.

“S” is related to “M” and should remain OFF in most cases.

Set the Left-Right Switch.

Set the 932 Left-Right switch to indicate its position on the right or left side of the speaker portion of your display. 932s are the only modules addressed identically, but the Left-Right switch lets the control panel tell them apart. Set the switch to RIGHT if only one channel (a single 932) is used, as in the case of mono subwoofers.

Set the Address Switches.

Set and recheck all the address switch settings. Setting the address switches is very important. All functions of the AccessSystem depend on correct addressing of the switch modules. Please take the time to double check the labels and subsequent module addresses that you may have set.

Timeout Minutes and Model 988.

Figure 19. The 932 module serving the left channel of speakers 9-16 (note the filled-in identification boxes).

Model 988 (if included in your system) can monitor system activity and restore system volume to a standby level

during idle periods. This time period is called “Timeout” and is counted from the last Master Volume control change or AccessSystem command such as product selection. Set the 988 “Timeout” DIP switches to total the desired timeout period. For example, if you turn on switches 1 and 2, your system will timeout after 3 minutes. If you do not wish to use the Timeout feature, leave the three Timeout switches turned OFF.

SilenTouchand Model 988.

The Model 988 can administer SilenTouchin systems with no 980 module. If both modules are present in a system, turn the 988’s SilenTouch switch OFF (the bottom switch on the 4-switch array).

Speaker Limit.

The Access System is designed to allow multi-channel amps to play a set of car speakers by separating them into product groups. One amplifier plays two Fronts, two Rears, and two Subwoofers. Addi- tionally, Access allows a default of two speaker pairs to play at once in the same Product Group (e.g. two pairs in the Front Speaker Product Group). Some stereo amp manufacturers do not recommend playing more than one pair of speakers at a time. If customers will have access to your display, consider using the lowest Speaker Limit recommended for any amplifiers you are demonstrating. You may set the Speaker Limit to 1, 3 or 4 pairs with the switch array labeled SPEAKER LIMIT on the Model 980 (default is 2 pair). If your system has a Model 988 instead of a Model 980, the speaker limit is set at two.

E. Fill out the identification boxes.

Fill out the identification boxes printed on the case of main modules to reflect the address and other settings on each module (see Figure 19). This will help with installation and troubleshooting later.
