IMPORTANT: The following options are provided for enthusiasts and installers who wish to experiment with their systems.

a. THX Dipole Mode
See page 6. To operate in the Dipole (THX) mode, connect the positive (+) lead to Terminal 1. Use no jumper.
b. Tripole Mode
See page 6. To operate in the Tripole mode, must connect the positive (+) lead to Terminal 1 and insert the jumper between terminals 3 and 4.
c. Tripole With Attenuated Dipole Elements
Compared to the standard Tripole configuration, the output from the Direct (front) drivers will be unchanged, but there will be significantly reduced output from the Dipole (side) drivers.
To attenuate the Dipole elements, connect the positive (+) lead to Terminal 3, and insert the jumper between terminal 3 and 4.
d. Tripole With Adjustable Attenuated Direct Radiator
Compared to the standard Tripole configuration, the output from the Dipole (side) drivers will be unchanged, but there will be reduced output from the Direct drivers. This configuration will give you a sound more like the THX Dipole configuration.
To adjust the attenuation of the Direct Radiator element, connect the positive (+) lead to Terminal 1 and insert a 5 watt resistor between terminals 3 and 4. The resistor can be any value between 2 and 11 ohms. The larger the value of the resistor, the greater the attenuation.
e. Tripole With Adjustable Attenuated Dipole
To adjust the attenuation of the Dipole element, connect the positive (+) lead to Terminal 3 and insert a 5 watt resistor between terminals 3 and 4. The resistor can be any value between 2 and 11 ohms. The larger the value of the resistor, the greater the attenuation.
f.Tripole With Maximum Output From All Drivers (2.4 ohm impedance)
Compared to the standard Tripole configuration, the output from the Dipole (side) drivers will be unchanged, but there will be significantly greater output from the Direct (front) drivers.
To get maximum output from all drivers, connect the (+) lead from the amplifier to Terminal 1. Connect a jumper wire between Terminal 1 and Terminal 3. CAUTION: This configuration presents a 2.4 ohm load to the amplifier. Do not use this configuration unless your amplifier is rated to 2 ohms.
g.Direct Radiator Only Mode
There will be very little (virtually no) output from the Dipole (side) drivers.
To operate as a Direct Radiator, connect the (+) lead from the amplifier to Terminal 3. Use no jumper.
Remember, regardless of configuration, the Ground
REMOTE SWITCHING OF MODES
If you want to be able to switch between any of the above modes, you can do so by using a speaker level switch box. The specific instructions will vary according to the particular switcher you are using and the , so this is section is intended to be general in nature.
For example, to switch between THX Dipole mode and Tripole mode, connect one wire between Terminal 3 and the switcher Input. Connect a separate wire between Terminal 4 and one of the switcher outputs. For the THX Dipole mode, the switcher output connected to Terminal 4 should be turned off. For the Tripole mode, the switcher output should be turned on. Nothing else should be connected to the switch box, especially your amplifier.
As another example, you can also use a switcher to direct the (+) signal from the amplifier to either Terminal 1 or Terminal 3, to switch between some of the custom modes described above.
CAUTION: DO NOT WIRE THE SWITCH BOX SO TERMINAL 2 CAN BE CONNECTED TO ANY OTHER TERMINAL. If Terminal 2 is connected to Terminal 1, 3, or 4, the output of the power amplifier will be shorted, which will almost certainly damage the amplifier.
