Setting up the Subwoofer
FRONT LEFT SUBWOOFER CENTER SPEAKER MINI HIFI SYSTEM
â¢ If the subwoofer is placed in the center of a room, the bass could be extremely weakened. This is due to the influence of the standing wave of the room. If this happened, move the subwoofer away from the center of a room or eliminate the cause of the standing wave, by installing a bookshelf on the wall, etc. Important: Before you operate the subwoofer, complete the preparation procedures. Switch on your mini system and select the sound source.
Switching the subwoofer to standby mode
â¢ Rotate SUBWOOFER VOLUME counter-clockwise until there is a click. â¢ The LED indicator light turns red.
PHASE SELECTOR 00 180 0
Use PHASE SELECTOR located at the rear of the subwoofer to select the phase polarity. Selecting the polarity at either 0Ë or 180Ë may determine better bass reproduction effect in certain listening environments (depending on the type of front speakers and the position of the subwoofer). It may also change the expense and tightness of sound, and affect the feeling of sound field. Select the setting that provides the sound you prefer when listening in your normal listening position. Repeat the adjustment for Volume and Phase Polarity to suit your preference. Once you have adjusted the subwoofer to the settings you desire, use the VOLUME control on the mini system to adjust the volume of the subwoofer and the other speakers. You do not need to adjust the subwoofer settings again even when you change the volume level of the mini system.
You can adjust the subwoofer to suit the sound level of your front speakers. Reinforcing the bass sound gives you a greater sense of atmosphere. 1 Adjust the VOLUME on the mini system until the sound from front speakers is not distorted. If it is distorted, the sound from the subwoofer will also be distorted. 2 Play your favourite songs. Male vocal tunes containing bass sounds are most suitable for adjustment. 3 Adjust the SUBWOOFER VOLUME to determine the loudness of the bass sound from the subwoofer.
â¢ Install the subwoofer wherever you like because with the bass sound range reproduced from the subwoofer (below 150Hz), human hearing cannot detect the direction and position in which the sound is being produced. â¢ Also, since the feeling of stereo is lost with bass frequencies, a single subwoofer is enough for reproducing the bass of stereo channels. However, you may install more than one subwoofer if your system has more than one subwoofer out jack. â¢ To obtain a better bass reproduction, we recommend that you install the subwoofer on a solid floor where resonance is unlikely to occur. â¢ Always place the subwoofer vertically, keeping a few centimeters from away the wall. â¢ Do not place an object on the subwoofer or sit on it.
