Page 8: Practice Of Sound / Installation And Placement Tips
Practice of sound / Installation and placement tips This chapter contains common information on loudspeaker placement and installation. This is general rules, so there are exceptions of some rules In which room do No matter how good the equipment is, in the wrong listening environment it will inevitably sound bad. - Page 9 Cables Try to keep them as short as possible. By its electrical parameters, a long conductor will have a bigger influence on the sound than a short one. It may also work as an antenna and thus receive various signals that may become a constant noise in an active subwoofer.

Page 10: Mounting
Mounting Mounting 99 W12 DSP give you much freedom to place the subwoofer anywhere. Example: With the function “DELAY” the subwoofer can be placed near the listening position with shorter distance to the listener than the front system, and delay the sound to the subwoofer so you get no phase and time problem between the front system and the subwoofer. -

Adjustable from 10-40Hz.
- Page 16 How to use function The subsonic filter cuts unwanted frequencies in the deepest bass range. An example of unwanted 12 and 13 sound is "rumble" from a turntable or wind noise from a microphone. The reason to cut these unwanted frequencies: - To decrease the noise level in the listening room.

- Page 18 How to use function Incorrect frequency, polarity and phase alignment between the main loudspeakers and subwoofer 14, 15, 16 and 17 causes a gap in the frequency response of the whole system at the crossover frequency. The graph to the right shows the effect of phase difference to the frequency response.

Technical explanations Slope The slope is commonly used to describe the steepness degree of the filter. A higher slope value indicates a steeper filter. Boundary Cut off frequency (fc) is the frequency either above which or below which the power output of a circuit, frequency/Cut off such as a line, amplifier, or filter, is reduced to ½... - Page 24 Room modes Room modes come from reflections in the room. Sound directly from the speakers and sound reflections forms a pattern in the room. Same frequency in phase gives you room modes If the frequency is in opposite phase, they will put out each other and you get a dip.
