To remove the rack ears, first turn off the amplifier and remove the power cord. Undo the three screws holding each rack ear in place. Remove the rack ears and keep them in a safe place in case you need them in future. Replace the three screws back into the amplifier and tighten securely.

7. Balanced (XLR) Input

Connect these identical balanced in- puts to the balanced line-level sub/LFE output of a Home Theater preamplifier, receiver, or other source.

Balanced connections offer superior noise cancellation over unbalanced connections. You can use either XLR balanced, or RCA unbalanced inputs, with XLR preferred if you have a choice.

If your preamplifier or receiver has a single sub/LFE balanced output, con- nect it to either of these inputs, leaving the other one unused.

8. Line Level (RCA) Inputs

Connect these identical unbalanced inputs with RCA type patch cords to the line-level sub/LFE outputs of your Home Theater preamplifier, receiver, or other source.

If your preamplifier or receiver has a single sub/LFE output, connect it to either of these inputs, leaving the other one unused.

If your preamplifier or receiver does not have a sub/LFE output, use “Y” adapt- ers at the preamplifier outputs. In this way, you can send the preamplifier’s output signals to your main amplifier and to the subwoofer amplifier at the same time.

9. Trigger Inputs

This input can be used to automatically turn on the amplifier. To do this, con- nect a 12 VDC source as follows:

Input voltage range: 2.2 - 13 VDC

Impedance: approximately 2800 ohm

(4.2 mA @ 12V)

3.5 mm mono mini-jack, tip positive

Some Home Theater preamplifiers and receivers, such as the Sunfire Theater Grand series, have matching 12 VDC Trigger outputs. When they are turned on, the amplifier will turn on.

10. Ground Terminal

This screw terminal is provided in order to ground the amplifier. In some cases, grounding may eliminate noise due to a ground loop in the system.

11. IR Input

This IR input can be connected to the output of an optional external IR receiv- er. The amplifier can then be controlled in the same way as using the remote control and pointing at the internal IR receiver on the front panel.

12. Service

This connector is provided for use by Sunfire service technicians only.
