NOTE: When a DD subwoofer detects an incoming RS-232 command, it reverts to “Slave
Mode”. This means that the subwoofer will no longer accept IR commands. To reestablish
normal operations, remove the RS-232 cable and power cycle the unit.
Note that the daisy chain connection ONLY allows the woofers to communicate basic “run-time”
commands such as volume and preset. W
e recommend the following sequence when setting
up daisy-chained subs.
1.
First, connect only the master sub to the system. Do not connect the thru or serial
cables at this time.
2. Establish the crossover, phase, and other settings EXCEPT the EQ on the master sub
(see setup steps 1 17 starting on page 17). Note the low pass crossover, phase
and polarity settings, then save.
3.
Connect the video out of the slave subwoofer, go to the settings screen, establish the
low pass crossover, slope, phase, polarity, and night mode settings from the master
subwoofer, then save settings. Repeat for each slave subwoofer in your system.
4. Connect the microphone to the slave subwoofer and use the “self-EQ” feature
(described below) to establish room EQ for that subwoofer
.
5. Repeat steps 3 and 4 for each slave subwoofer in your system.
6. Reconnect the video out to the master subwoofer, and reconnect the thru and serial
cables so that the master and slave subwoofer (s) are daisy chained.
7. EQ the primary subwoofer (see steps 8-25 starting on page 20). Self-EQ is NOT
recommended for the primar
y subwoofer.
8. Setup is complete!
