Align the two modules to be joined on a tabletop or on the floor so that the top of the lower one and
the bottom of the upper one are close to one another, say 4” (10 cm) apart.
Insert the free end of the short ribbon cable into the socket on the second module. Using a #1 Phillips
screw driver, secure the connector with two 4-40 Phillips head screws (supplied). Make sure the con-
nectors are fully seated. If necessary, use a flashlight to check because if the connectors are not seat-
ed properly, you may have to disassemble the column again in order to seat them correctly.
Align the two modules and slide them together, making sure the holes in the heavy joining plates align
with the holes in the modules. Install the remaining screws into the joining plates and tighten all the
screws. The assembly is now complete.
Address Number Verification
All that remains is to identify which module is the Master and which are Slaves. These were set at the
factory, but it’s always a good idea to check the settings. This is accomplished with the Master/Slave
dip switches located on the input panel. See page 50 for a detailed view of the input panel.
Normally the bottom module will be the Master and the other modules will be the Slaves numbered 1,
2 & 3 in ascending order. However, as long as the switches are set properly any module can be desig-
inated as the Master. You may, for example, designate the top module as the Master to allow you to
bring the signal cables into the top of the array. Set the switches in accordance with the drawing shown
below. On single IC8-R arrays the dip switches should always be set to the Master setting (“00”).
Be aware that certain functions will be disabled on the Slave modules as their control has been turned over to the Master module.
Preset Up, Preset Down, Preset Enter , Input Pad, Volume Up & Volume Down, AES/EBU Input and Mute functions are all controlled
only by the controls on the Master module. Signal cables must be brought into the Master module. AC power can be brought into any
module.
Note that if you connected power to the Array before setting the dip switches, you will need to disconnect it and reconnect it before the
dip switch settings will take effect.
