Introduction Thank you for purchasing this Sunfire ATMOS Subwoofer. We hope you enjoy it and the music it makes as much as we have enjoyed creating it for you. The big breakthrough features of the subwoofer are its uncanny tracking downconverter, its long throw, high back-electromotive force driver, and its fully automatic room equalizer. Taken together, they provide this subwoofer with as much bass as you could get from several 15 inch drivers mounted in a cabinet the size of a small refrigerator.
Overview Your Sunfire ATMOS Subwoofer is designed to give you the best possible low-frequency sound quality for your Home Theater experience. It incorporates a tremendously powerful built-in amplifier and a pair of drivers to produce tight, floor-rumbling, denture-rattling bass that you can feel as well as hear. The subwoofer has an automatic equalization system which will tailor the subwoofer output to compensate for any room effects.
Control Panel Features 1 2 3 5 6 8 4 7 9 10 11 1. Crossover Frequency This control changes the high frequency cutoff point. With the control set to 100 Hz, the subwoofer will reproduce frequencies up to 100 Hz. If the control is set fully clockwise, the crossover is bypassed and the subwoofer will reproduce a wide frequency range. With the control fully counter-clockwise the subwoofer reproduces a narrow range, up to 30 Hz. Rotate the control until the bass sounds natural.
5. Line-Level Inputs 8. Slave Input and Output Connect these unbalanced inputs with RCA type patch cords to the line-level outputs of your receiver or preamp. These connections simplify the hookup and operation of two ATMOS subwoofers. If your preamplifier or receiver has a single sub/LFE output, connect it to either input jack (see page 14). Connect the slave output from the first subwoofer to the slave input of the second.

The outlet must have a circuit rating of 6 amps or more. Never plug the EURO (230 VAC) model subwoofer directly into 120-130 Volts AC. 11. Line Fuse The subwoofer is supplied with a conservative slow-blow type fuse to protect the electronics.
Installation Observe the following general precautions and read the safety instructions on pages 2 and 3 before using your Sunfire Subwoofer. • Never open the cabinet or remove the metal control panel as this might result in an electrical shock to you, or damage to the unit. • Protect it from prolonged exposure to direct sunlight and other direct sources of heat, such as heating vents and radiators. • To prevent fire or shock, do not expose the unit to rain or moisture.
Connections Please consider the following when setting up your new system : • • 10 Before making or changing any connections, ALWAYS make sure that the subwoofer and your other components are turned OFF. Also turn down the volume control of the subwoofer and your preamplifier or receiver. This diagram shows all the low power components sharing a power strip which is connected to the same outlet used by the amplifier.
Location Your subwoofer is designed to be placed in a corner and this will produce optimum performance. #1 is very good positioning. #2 is also excellent but may shake the back wall too much and cause things on or along the wall to rattle too much. If this occurs, use the #3 position: #3 Move the subwoofer approximately three feet away from the right wall and place it along the back wall as shown.
Room Equalization Procedure Subwoofer performance is greatly affected by the room in which it is situated, and the positioning within the room. The room effects will boost and cut the output levels reaching your listening position. This gives a "Room EQ" effect which can often be far from wonderful. The Sunfire ATMOS can automatically adjust for the effects of Room EQ. It measures the actual frequency response using the supplied measurement microphone.
11. Unplug the microphone and store it in a safe place. 12. Finish the setup by adjusting the Atmos VOLUME, CROSSOVER and PHASE appropriately and calibrating your surround sound receiver/processor according to its owner’s manual. 13. If you add/remove heavy draperies or large furniture or move the Atmos to a new acoustic environment repeat steps 6-12. Resetting the EQ 1. Turn off the subwoofer using the AC power switch. 2. Hold down the Start button and turn on the AC power switch. 3.
System Configurations The following pages show some typical connections that you might make in your installation. They show how the inputs and outputs of the Sunfire Subwoofer are connected to your preamplifier or receiver. Connections to a preamplifier’s subwoofer output If your preamplifier has a subwoofer output (often labeled LFE for Low Frequency Effects), it can be connected to the subwoofer’s left or right input as shown. This is the simplest and recommended connection.
Connections to a preamplifier using Y cables If your preamplifier does not have a dedicated sub/LFE output, you can use “Y” cables to send its main outputs to both the subwoofer and your amplifier. The subwoofer will play the low frequency range and your front speakers will play the full range. Although bass is commonly distributed evenly between left and right channels (L+R bass), movie soundtracks often contain differential (L-R) bass.
Using the line-level outputs If you are using a preamplifier that does not have a sub/LFE output, you can send its left and right front output into the subwoofer’s line-level inputs and then connect the subwoofer’s line-level outputs to the inputs of your amplifier. The subwoofer will play the low frequencies and your amplifier and front speakers will play the frequency range of the subwoofer's outputs. The subwoofer's output switch lets you select BYPASS or 85 Hz.
Using the slave input and output The SLAVE output from one ATMOS subwoofer can be connected to the SLAVE input of a second ATMOS subwoofer. The second subwoofer will then receive the optimum audio signals from the first. There is no need to adjust the controls of the second subwoofer, as the audio is controlled by the controls and EQ setting of the first. The second subwoofer does not require any connections to its line-level inputs.
Adjusting the controls There are two main methods for adjusting the level, crossover frequency and phase of the Sunfire Subwoofer to match a system: • Bob Carver’s preferred method: By listening and making the adjustments to suit your taste. • Laboratory method: By measuring the output and adjusting for a flat frequency response. Excellent results can be obtained if you make the adjustments based on simply listening.

User's Manual
Troubleshooting The Sunfire Subwoofer is expertly designed and built to provide years of trouble-free performance. Most problems that occur can usually be solved by checking your setup or making sure that the components connected to the amplifier are on and fully operational. The following information will help you deal with common problems you may experience during normal use. If a problem still persists, please contact your Sunfire Dealer for assistance. • Not enough bass in a 5.1 system • 5.
Hum Adding any component such as a subwoofer to an existing system will often give rise to a hum which wasn’t there before. Your first thought may be that the subwoofer has a problem, but this is more than likely caused by a “groundloop” in your system. Follow these steps to isolate the main cause of the ground-loop hum (there may even be more than one cause). • Try to have all of your equipment on the same electrical outlet or circuit, see page 10 for more details.
