Removing the Pre-Installed DAS-AMFM Tuner Module

Mi Series Audio Controllers include one DAS-AMFM Tuner Module as a standard 
accessory. Since each tuner module uses one source input on the audio controller, in some 
cases it may be desirable to remove the tuner module in order to use that source input for 
other purposes.
1.

Remove the cover from the controller.

2.

Carefully remove the ribbon cable from the tuner module.

3.

Remove the screws from the Tuner module cover plate at the right top corner of the 
rear panel and slide the tuner module out of the chassis.

4.

Place all jumpers in the “Off” position (FIG. 9). 

5.

Replace the unit cover.

Installing a Second DAS-AMFM Tuner Module

The following steps describe installing a second DAS-AMFM tuner module into Slot 1 (in 
addition to the DAS-AMFM module that comes pre-installed in Slot 2). In these instructions, 
the second tuner is referred to as “Tuner 2”.
1.

Remove the cover from the controller.

2.

With the back of the unit facing you, remove the screws from the Tuner Option cover 
plate at the right top corner of the rear panel (FIG. 10) and remove the plate. Retain 
the screws, as they will be used to install the tuner module. 

3.

Carefully insert the second DAS-AMFM tuner module into Slot 1, with the electronics 
facing up, and use the screws that attached the Tuner Option cover plate to secure 
the tuner to the controller.

Note: Be careful not to damage the ribbon cable on the top of the Tuner module.

4.

Place the Rear Panel connector at the end of the ribbon cable (FIG. 11) on the 
Interface Board pin-bus, keeping the red stripe at the top. 

5.

Connect the "

Slot 1

" connector on the ribbon cable to the Tuner 2 module (FIG. 12). 

Note: The ribbon cable must be oriented so that the red stripe is connected to Pin 1 
on the connector.

Verify that both ends of the cable are securely plugged into their respective boards 

through the 20-pin connectors (FIG. 13).

6.

Replace the two screws that were removed when the Tuner Option cover plate was 
removed to secure the faceplate of the DAS-AMFM to the controller. 

FIG. 14 provides a view of the inside of the controller, with two tuners installed.  

Note: While it is recommended that you use the Slot 2 connector on the ribbon cable 
to connect the Tuner installed in Slot 2 (in this case, the DAS-AMFM Tuner), the 
ribbon cable itself does not determine which Tuner is Tuner 1 and Tuner 2. 
This determination is set by the jumper settings on each Tuner Module (see “Dual 
Tuner Installation Instructions” above). 
Therefore, it is not required that the connections indicated in FIG. 11 are followed 
exactly, as long as the Tuner Jumper Settings are set correctly for each Tuner Module 
installed.

7.

On units with green Interface Boards only: 

Connect the supplied cable from the tuner 

to the Interface Board as shown in FIG. 15. 

Note: The 3-wire end connects to the open pins on the Interface Board with the white 
wire pointed up.

8.

Use the supplied cable ties to secure the cable loosely as illustrated in FIG. 16:
