Sunfire CRS-3C manual Break-in period, Crossover adjustment

Crossover adjustment

We recommend that you set your home theater processor's crossover to 80 Hz, and set the channels that use the Cinema Ribbon Trio loudspeakers to "small."

•Your subwoofer receives frequencies below 80 Hz, from all loudspeakers whose size is set to small, in addition to the LFE channel:

NOTE: If your processor or preamplifier does not have a crossover control, you might need an external active crossover to split the audio signal into a low-pass range for the subwoofer, and a high- pass range for the Cinema Ribbon Trios. (Sunfire subwoofers have their own crossover controls with line-level high- pass outputs that can be used to power an amplifier connected to Cinema Ribbon Trio loudspeakers.)

•All loudspeakers set to small, receive frequencies above 80 Hz.

•Set your subwoofer's own crossover control (if it has one) to maximum frequency or bypassed mode. (If it is set lower than the 80 Hz, there would be a hole in the mid-bass, and bass informa- tion would be missing.)

The acoustic summation of the subwoofer output and the Cinema Ribbon Trio output produces a flat frequency response.

NOTE: Dolby Digital and DTS modes are designed especially for complete systems with front, center, and surround loudspeakers and subwoofers. You need all of the loudspeakers to get the best performance from your Home Theater. If you do not have a subwoofer connected, you will be missing the 5.1 LFE (low frequency effects) information.

Break-in period

Like many high performance automo- biles, the Cinema Ribbon Trio loudspeak- ers perform at their best after an initial break-in period. A minimum of 20 hours is recommended prior to performing critical listening, however the speakers will sound their best after a period of 300 to 400 hours. During this time, the driver suspensions and ribbon structure will relax into their operating design positions and give optimum performance.

To facilitate break-in during the initial 20 hours, it is recommended that you play material with a wide dynamic range at louder volumes – such as your favorite rock and roll album (that is if your family or neighbors can stand it).

It is important that your amplifier must supply good clean power,

and not run into distortion. Amplifier distortion due to clipping, causes

high-frequency output components that can damage loudspeakers. Even a 100 watt amplifier running into clipping can damage loudspeakers rated at 400 watts or more.
