Introduction Features Thank you for purchasing this Sunfire True Subwoofer EQ. We hope you enjoy it and the music it makes as much as we have enjoyed creating it for you. • 2,700 watt, high efficiency amplifier • High gloss, dark rosewood finish (also referred to as Deep Bing Cherry Lacquer) 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.
Overview Your Sunfire True Subwoofer EQ 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 is available in two versions, and this manual covers both: Signature Edition is a 13 inch cube, with an output greater than 116 dB peak SPL, 16 Hz to 100 Hz.

Volume This control lets you match the output level of the subwoofer to the level of your satellite/main speakers. The subwoofer output will increase as this control is rotated clockwise. When you have just installed your system, turn this down first before turning on your subwoofer. This will prevent any loud surprises. 2. Crossover Frequency 6 8 3.
passive network with a fixed crossover frequency of 70 Hz and a 6 dB per octave slope. We recommend using this high-pass function with main/satellite speakers that are small and not designed to reproduce low frequencies. If your main speakers are capable of operating full range, then you will not need to use the high-pass function. To use the high-pass outputs, connect the preamp outs on your preamp/ receiver to the subwoofer’s line level inputs using good quality RCA type patch cords.

The outlet must have a circuit rating of 8 amps or more. Never plug the Euro (230 VAC) model subwoofer directly into 120130 Volts AC. 11. Power Switch The power switch is a CE requirement for international shipments. Leave it switched on at all times for normal operation. After a period of inactivity (i.e.
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 : • 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. • Whenever possible, keep the power cords away from the signal cables or speaker wires to prevent any hum or interference being heard in the speakers.
Location you might be able to place the subwoofer. Try crouching down, and try the corners. Find the place where the subwoofer's bass output sounds the loudest. 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.
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. 3. Place the microphone in the listening position (on the couch, for example), pointing in the direction you’ll normally be facing while listening to your system. Only use the microphone supplied by Sunfire.
9. The sub automatically calculates the best equalization, based on the measured frequency response at your listening position. This will be saved, before returning to the normal listening mode. 10. In normal listening, you can adjust the overall effect of the saved EQ settings with the Equalizer Authority control. Normally you would turn it to 100% for full equalization. You can turn it to 0% to judge the effect of no equalization, or vary it to suit your taste. 11.
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 (Mono) input as shown. This is the simplest and recommended connection.
Connections to a preamplifier using Y cables If your preamplifier does not have a 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. DIM - STANDBY BRIGHT - ON 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 high-pass outputs If you are using a preamplifier which 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 High-Pass outputs to the inputs of your amplifier. DIM - STANDBY BRIGHT - ON The subwoofer will play the low frequencies and your amplifier and front speakers will play the frequency range above the subwoofer’s fixed high-pass crossover point.
Using the speaker level inputs If you are using a receiver which does not have a subwoofer output or line level outputs (pre-outs), you can connect its speaker outputs to the subwoofer’s speakerlevel inputs. The front speakers can still be connected to your receiver. DIM - STANDBY BRIGHT - ON The subwoofer’s internal amplifier supplies the power to reproduce the low frequency range. It receives a sample of the signal going to your front speakers.
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.

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.
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.
