6.4.7 External Functions (SMX-6 Mixers Only)
(Figures 6.13 and 6.14) External functions are unique to SMX-6 mixers and each one must be connected to a
Crown Local Net (CLN). Select the “External Algos” control and press the “Space Bar” to bring up the External
Functions window shown in Figure 6.14. Note: An “algo” is a function and this manual substitutes the word
function except when referring to a control with algo in the name.
An external function is one which is controlled, in part, by other IQ components. For example, more than one

SMX-6 can be linked in a CLN so their Duck Priority and Gate Count functions work together. A priority 1 input in
one unit will override a priority 2 input in another unit. The number of open mics can be totalled among all the SMX-
6s in a CLN and all open inputs attenuated to prevent feedback in a large IQ System.
The CLN must be started in a particular order for reliable operation of the external functions. The procedure is
listed below:
1. All SMX-6s
must be connected to the system via the Crown Bus.
2. All ASA controls must be turned on.
3. With the CLN wiring
disconnected and the System control of the External Functions turned off, set the
Master, Ext Algos, Duck and Gate Count controls.
4. Connect the CLN serial cables as described in the IQ Mixer Hardware Installation or Reference Manual.
5. Select the master SMX-6 in the External Functions window and turn the System control on. The CLN and
external functions will begin to run.
After the CLN has been properly initialized, the System control can be turned on/off at any time to enable or disable
CLN communication.
WARNING: You will be locked out of any further
serial port communication with an
SMX-6 when you initialize the CLN. This means you cannot use an SMX-6 as an IQ interface at the
