Tango Series Audio Controllers
Speaker Wire Technology (SWT)
Speaker Wire Technology (SWT) allows both data and audio signals to travel over the same four
conductor wire. This remarkable technology removes the need for control wire since the control and
audio signals are shared on the same wire. The reliability and simplicity of this system has been proven
for years. AMX Matrix Audio is the only company that offers a “retrofit solution”, one which allows the
replacement of volume controls with AMX Matrix Audio keypads and Controllers, giving full control
over the sources. Additionally, the versatility of SWT also allows AMX Matrix Audio products to be
connected where the control wire has been run separately from the speaker cable.
Cabling Installation Instructions
This installation uses low voltage cabling similar to telephone and alarm wiring, and as such does not
commonly have very many restrictions on their installation. However rules may vary in different regions.
Cable Type
The Tango Controller is cabled using standard 4-conductor speaker cable originating at the Tango
Controller, passing through the Keypad, and terminating at the speaker location. AMX generally
recommends using a bundled 4-conductor 16-gauge stranded copper wire in a single continuous run.
