C. Set the Address Switches.
Some Group settings are made at the factory, and cannot be changed later. Figure 16 shows the first switch module (Model 910D) in the first Product Group (head units). It has a default address of Group #0 (set at the factory) and the Module ID is set to #00 (this lets the system know this module is connected to the first four products in this product group). The second 910 would be addressed 01, and the third module, 02, etc. Always start with zero, not one, for the first module in any group.
Figure 17 shows the address settings for the fourth module in the Processor/EQ Product Group. The group default is #2 and the address is set to #03.
D. Set the Programming Switches.
Figure 16. First head unit Module with the
address 0/00 (Group/Module ID).
Programming Switch Settings “S M B T D.”
Models 910, 940EZ and 942 have a DIP switch array with small rocker switches labeled S M B T D (Model 910 has T and D only). The slide switches are set to “Off” at the factory. The switches are defined as:
S | M | B | T | D |
Single | Multi- | Bypass | Time | Delay |
Stereo | Channel |
|
|
|
“D” turns on the DC Power Delay feature and works with the Power Mode switch setting on the 980 module. Use the following chart to determine switch settings. Set the 980’s “Power Mode” switch and each main module’s “D” and “T” switch using the chart below.
Figure 17. This Model 958 would be the
fourth and last module in group 2
(Processor/EQs), because bypass is ON.
Figure 18. The thirteenth (and last) module in Group 4 (Front Amps). Bypass is ON (“B” in programming switch array SMBTD).
Mode | Effect on | Power Mode | Delay or “D” Switch |
| Product Groups | Switch on 980 | on Main Modules |
|
|
|
|
Power Conserve | 1 unit ON; | ON | ON |
| delayed |
|
|
Smart Power | Up to 3 units ON; | OFF | ON |
| delayed |
|
|
Continuous Power | All units ON; | OFF | OFF |
| no |
|
|
|
|
|
|
“T” sets the amount of time delay to allow for product
“T” - ON = 3 second delay for high power amps using switching power supplies.
The “T” switch should be OFF (3/4 second delay) for 910 modules, and ON for 942 modules (3 second turn- on delay for large power amps).
