The Subwoofer is a virtually omnidirectional speaker, so it can be installed in almost any location. For example, the Subwoofer can be installed next to the component system (consisting of an amplifier, tuner, cassette deck, etc.), or in a corner of the room, etc. The Subwoofer’s deep-bass reproduction characteristics are richest when the Subwoofer is installed in a corner or near a wall. Since the low-bass component in music is usually monaural, only one Subwoofer is necessary to obtain a sufficient stereo effect when used in combination with a stereo music system.

Howling

If the Subwoofer is installed near an analog record turntable, a howling sound may be generated. If this occurs, place the Subwoofer farther away from the turntable or reduce the Subwoofer volume (By rotating the VOLUME CONTROL counterclock-wise). The howling phenomenon may also occur due to cross interference with a cas- sette deck, compact disc player, or Laserdisc player, although this is very rare. If sound or picture seems to be distorted due to this reason, place the Subwoofer farther away from other components or reduce its volume.

Operation near a TV

If the Subwoofer is installed too close to a TV, color irregularities may be observed on the TV screen. If such irregularities occur, switch the power of the TV to OFF and then switch it ON again after waiting for a period of 15 to 30 minutes. The influence of the Subwoofer on the TV picture may be improved by self-demagnetization of the TV set. If the color irregularities still persist, move the Subwoofer farther away from the TV.
