2. Set the Address switch on the rear panel of the Zone Expander to "1" if the Zone Expander services
zones 9 – 16, set to "2" for zones 17 – 24 and so on until all seven Zone Expanders are utilized (see
FIG. 10). Refer to the Zone Expander Addressing section on page 15 for further details.
3. Connect the source inputs. Patch each source from the source output on the Tango controller to the
source inputs on the Zone Expander.
Continue this procedure until each source is connected.
4. Paging Inputs are for Phone Systems or Communications Boxes. If the paging override is used,
connect the paging output loop from the Tango Controller to the Zone Expander (see FIG. 10).
5. Connect the keypads to the Tango Controller and Zone Expander(s). Following the same wiring
code you used at each of the keypad locations, plug each SWT connector into the desired Zone
Output connectors on the Tango Controller and Zone Expanders (see FIG. 10).
6. SWT Speakers connect to the Tango Controller via the SPEAKERS connector on the SWT keypads.
See the Connecting Zone Outputs section on page 12 for details.
Alternatively, you can terminate the speakers directly to the back of the Controller. Speakers
connected directly to the zone output must be common grounded.
The minimum impedance for each zone should never be less than 4 ohms
7. On the Main Controller, make the necessary NIC Port connections for the (optional) Network
Interface Card and AM/FM Antennas.
8. Connect the power supply and power up the units.
Zone Expander Addressing
Use the 7-position Address switch (FIG. 11) on the rear panel of the Tango Zone Expanders to set the
Address for each Expander, according to the values in the following tables:
Ensure the left and right source connections are properly matched and seated to the
left and right terminals of the both the Tango Controller and the Zone Expander.
For example, Source 1 Output, on the Tango Controller to Source 1 Input on the Zone
Expander).
Installing more than 2 pairs of speakers on any Zone output is not recommended
without installing an external amplifier.
Refer to the Tango Zone Expanders Installation Guide for additional details.
