Sunfire Home Theater System Line-LevelInputs, Speaker-LevelInputs, Line Fuse, IEC Linecord socket

To use the high-pass outputs, connect the preamp outs on your preamp/ receiver to the subwoofer’s line level in- puts using good quality RCA type patch cords. Then connect a second patch cord from the subwoofer’s outputs to the inputs of your main amplifier. This will allow your main speakers to oper- ate at frequencies above 70 Hz and the subwoofer to operate at frequencies below 70 Hz (see page 13).

5. Line-Level Inputs

Connect these unbalanced inputs with RCA type patch cords to the line-level outputs of your receiver or preamp.

If your preamplifier or receiver has a single sub/LFE output, connect it to the subwoofer’s left input jack (see page 11). There is no need to use the subwoofer’s right input jack.

If you want to run your main/satellite speakers full range, use a “Y” adapter at the preamplifier outputs (see page 12). In this way, you can send the preamplifier’s output signal to your main amplifier and to the subwoofer at the same time.

6. Speaker-Level Inputs

Under normal conditions, the preferred connection is through the line-level inputs. If this is difficult or not possible in your system, then you can use the speaker-level inputs. Also, if you expe- rience excessive noise or hum with the line-level inputs, often a simple change to the speaker-level inputs will result in a lower background noise level.

Connect the speaker-level inputs to the speaker-level outputs of your amplifier or receiver using speaker wire. The binding posts can accept bare wire, banana, dual-banana or spade con- nections.

Your amplifier or receiver MUST have common grounded outputs, or it will be damaged if connected to the subwoofer’s speaker-level inputs.

7. Line Fuse

The subwoofer is supplied with a con- servative 4 amp slow-blow type fuse to protect the electronics.

Always unplug the power cord before inspecting or changing the fuse. Never use a fuse with a larger current rating than 4 amps.

8. IEC Linecord socket

The Sunfire Subwoofer comes with a detachable linecord which connects here.

Connect the linecord to the subwoofer before connecting the

other end to an 120 Volt, 60 Hz AC outlet. The outlet must have a circuit rating of 8 amps or more

(a typical home circuit is rated at 15 amps).

If you live in or move to a country where the power grid is 220-240 Volts, the subwoofer must be plugged into a step-down transformer that is rated at 500 watts or more.

Never plug the subwoofer directly into 220-240 Volts AC as this will cause catastrophic circuit failure.

9. Power/Auto on Indicator

This light is bright when the subwoofer is on, and dim when the subwoofer is in its standby mode. This is controlled by the AUTO ON/OFF circuit. The pres- ence of an audio signal turns the unit on. After approximately fifteen minutes of signal absence, the subwoofer will go to its standby mode.

The light will only go completely off when the unit is unplugged from the wall.
