  • Page 8: Level

    Level The level control knob allows for subwoofer output matching to the system. To obtain a neutral sound balance it is important that the subwoofer level is set correctly. To do this, adjust the control up and down until a natural sounding bass level is obtained in the system. Readjustment is recommended if any crossover and/or phase settings are changed on the subwoofer.
  • Page 9: Input Terminal Right And Left / Input Terminal Mono

    Input terminal Right and Left / Input terminal Mono This subwoofer provides 3 low level inputs: Left, Right, and Mono. These inputs can be used in any combination. Signals from all 3 inputs are summed and fed to the subwoofer. Do not connect any of these inputs to high level signals such as power amplifier speaker outputs! If a SUB OUT terminal (or equivalent) is not present on the pre-amp/processor, then connect...
  • Page 10: Utility Link Terminal Input/Output

    Utility Link terminal Input/Output If two Dynaudio subwoofers are to be used, they may be connected via the Utility Link. With this link a total of six input terminals is possible. This feature is intended for use with a multi- channel surround sound system.
  • Page 11: Protection Circuit

    Protection circuit To prevent thermal overload, the mute circuit will be activated at 65 C (149 F) and will be automatically deactivated when the temperature drops to 50 C (122 F). Under normal conditions this should rarely occur. Power switch Switches the power on and off.
  • Page 12: Installation

    Installation CAUTION Switch off all equipment before any installation! If the sound system has a SUB OUT terminal (or equivalent), connect the subwoofer to this terminal. (Fig. A) If the system does not have a SUB OUT terminal (or equivalent), connect the subwoofer input to the PRE OUT terminal on the equipment (Fig.
  • Page 13: Multi-Channel Sound System

    If multiple Dynaudio subwoofers are to be used, connect them with the Utility Link <Utility In/Out>. Connect the Utility Link between two subwoofers as shown below. Example: two subwoofers will act as one big subwoofer with a total of six inputs, three on each.
  • Page 14: Positioning

    Positioning Useful hints: Best results are usually achieved with the subwoofer aimed towards the listening area, positioned between the main loudspeakers and near the wall. Both the floor and the walls will enhance the sound output. If the subwoofer is placed in a corner, maximum sound output will be achieved, but the quality of the stereo image may be sacrificed.
  • Page 15: Troubleshooting

    Troubleshooting No sound If there is no sound from the subwoofer, please check the following: Is the <Power switch> on? Is the <Level> positioned at minimum? Is your cable connected to output instead of input? Is the back plate very hot? Wait until it cools off. Is the audio system connected correctly? If there is any doubt, turn the power off.
