Introduction Congratulations on purchasing your Wisdom Audio SCS subwoofer. The Regenerative Transmission Line™ technology used in the SCS delivers tremendous bass performance in terms of depth, dynamics, and low distortion resulting in articulate bass that integrates seamlessly with high-resolution main speakers such as Wisdom Audio’s Sage Series. About this manual Please register your system This manual focuses on the SCS subwoofer itself.
Description Your Sage SCS subwoofer uses a modern implementation of an old idea for high quality, low distortion bass reproduction. While the roots of the Regenerative Transmission Line™ go back to the 1950’s, it is the combination of modern computer modeling and the vastly more powerful motors of contemporary driver design that make the RTL™ so special.
Unpacking the SCS The Wisdom Audio Sage SCS subwoofer is a substantial piece of equipment. Please exercise caution when unpacking your SCS to ensure that you do not strain yourself from its (perhaps unexpected) weight. Caution! Do not attempt to lift your SCS by yourself. Unpacking this subwoofer is easy for two people, but it is unwise for a single person to attempt doing so. Do not attempt to lift your SCS while bending or twisting from the waist. Use your legs for lifting, not your back.
Room Acoustics & Placement Wisdom Audio believes in implementing room equalization to achieve a higher level of realism and fidelity. Assume for a moment that you had a “perfect” loudspeaker: as soon as you place it in your room, its perfection is gone. In fact, even good rooms often introduce deviations of 20 dB to the response of the system. This is particularly true in the bottom two octaves, where a subwoofer operates.
The ultimate in dedicated listening room construction involves the design and construction of floating walls, ceiling and floor. This approach yields the added benefit (when done properly) of providing outstanding acoustic isolation from adjacent spaces as well as superb bass reproduction. This approach goes well beyond the scope of an owner’s manual; if you are interested, you should contact a professional acoustician who has specialized in this sort of domestic room design.
Surround Speakers Surround channel geometry In a 5.x channel system, the surround should be placed either directly to the sides of or slightly behind the listening area (90°–110° from the center channel, as seen from above). In a 7.x system, the surround speakers should be closer to 90° from the center speaker, and the surround back speakers should be at approximately 135°–150° from the center speaker.
Reducing the room’s inherent problems to this degree provides a huge advantage. It allows the SC-1 System Controller to put its considerable abilities to work on perfecting your system’s response, rather than on trying to perform major corrective surgery. Room Treatment Rectangular rooms have six reflecting surfaces (four walls, ceiling and floor) that reflect sound to the listener, after various delays introduced by the indirect routes the sounds take on their way to the listener.

Rear Panel Danger! Potentially dangerous voltages and current capabilities exist within your SCS subwoofer. Do not attempt to open any portion of the SCS’s cabinet. There are no user-serviceable parts inside your SCS. All service of this product must be referred to a qualified Wisdom Audio dealer or distributor. 1. Output Level Control When using the Left and Right inputs, this flush-mounted control adjusts the volume of the SCS over a wide range.
Caution! Always turn off the main power and wait a few seconds for the power supply to discharge before changing the position of the polarity switch. If you are in doubt as to which position (0° or 180°) is the correct one for your system, play some material with significant energy at and around your chosen crossover frequency. Pink noise will also work. Then listen to the system with both the SCS and the main speakers playing. The position with more energy at the chosen crossover region (e.g.
This control is bypassed when using the SSP/Direct input, since the crossover function is handled by the surround sound processor. 6. Power Switch An AC mains switch is located above the power cord on the rear panel of the SCS. This switch may be used to disconnect the unit from the AC mains without having to actually unplug the SCS from the wall outlet.
mm) “mini-jacks” allow other components to bring the SCS in and out of standby. The remote trigger input will be operated by any positive-polarity DC signal between 3–20 volts (only a few milliamps are required), with tip polarity as shown below: – Remote turn-on tip polarity + Input Signal: 3-20 volts @ less than 10 mA Output Signal: 12 volts @ 100 mA If no plug is inserted in the DC Trigger input, the SCS will remain in the Operate mode unless turned off by the power switch.
Setting Up the SCS The unusual form factor of the SCS allows it to be used effectively in many situations where a more conventional “bass cube” would be either cumbersome or impossible. Examples include locating it behind a couch, in the small space between the couch and the wall, or laying flat under a set of risers in a home theater with multiple rows of seating. The SCS also includes three locations for the exit of the Regenerative Transmission Line™.
1. Turn both the Crossover Frequency and Output Level controls all the way down. This will reduce the audible contribution of the SCS to the point of being negligible. 2. While playing your 40-80 Hz music, slowly raise the Output Level control until the bass seems just a bit too prominent, then back it off slightly. The goal here is to roughly match the overall level of the SCS to the overall level of your main speakers.
