Using the previous “pin-out” table as a guide, the following connections can be made:
•
Connect the bottom lead of all switches to Common (pin 6)
•
Connect the top lead of switch 1 to Input 1 Mute (pin 5)
•
Connect the top lead of switch 2 to Input 2 Mute (pin 4)
•
Connect the top lead of switch 3 to Input 3 Mute (pin 3)
•
Connect the top lead of switch 4 to Input 4 Mute (pin 2)
•
Connect the top lead of switch 5 to Input 1 Disable (pin 1)
•
Connect the top lead of switch 6 to Input 2 Disable (pin 9)
•
Connect the top lead of switch 7 to Input 3 Disable (pin 8)
•
Connect the top lead of switch 8 to Input 4 Disable (pin 7)
NOTE Remote control signals are st5 V CMOS logic levels or contact closures to
common.
Remote Control Operation
With the remote control unit (customer supplied) connected to the DMIX-41, two remote operating
modes are provided:
•
The remote “ Mute ” function allows you to select which inputs are mixed to the audio
output:
•
The remote “ Master disable ” function allows you to determine which input is used as the
output timing reference.
To mute inputs:
1. Using the appropriate “ Mute ” switches on the DMIX remote control, turn the desired
combination of inputs off . Inputs that remain on are mixed to the audio output.
NOTE
•
An input’s associated red ERROR LED will blink slowly when that input has
been muted via the remote control.
•
If an input is muted, it can still be the master.
To disable inputs as the master:
1. Using the appropriate “ Master Disable ” switches on the DMIX remote control, disable the
desired combination of inputs from being assigned as the master timing reference.
Note the following important points regarding the master assignment:
•
One of the four inputs must always be assigned as the master. If all error-free inputs are
disabled via remote control, the output signal will be muted.
•
Any input that is not displaying an error condition (as shown by a red ERROR LED) may
be used as the master.
•
If an input is enabled as master, its associated green MASTER LED lights continuously.
•
If an input is in use as the timing reference, its associated MASTER LED blinks slowly .
•
If an input is disabled from being the master, its associated MASTER LED is off.
IMPORTANT The DMIX uses a priority system for assigning the master. Of all the inputs
“enabled” as master, the lowest-numbered, error-free input is used as the
master timing reference. If the current master develops an error, the next
lowest-numbered error-free input automatically becomes the master.
