Accessories

Pin-plug cord.. 1 Cushion. 4 (1 sheet)

Attaching the cushions

Attach four cushions to the base of the subwoofer, one at each corner. The cushions prevent the subwoofer from sliding, and dampen its vibrations.

Installation

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 subwoofers 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 cassette 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.

Near the wall

Operation near a TV
If the subwoofer is installed near a CRT type TV set, the TV reception may be affected and interfered with color irregularities. Should color irregularities observed on TV screen, separate the Subwoofer from the TV until its reception becomes normal.

Far from the wall

Near the corner

Caution

Sound Pressure Level

To assure ventilation, observe the following points when installing the unit. Vertical installation Leave a distance of more than 10 cm between the Subwoofer back and the surrounding wall(s). Use special care not to cover the heat sink with a curtain, etc. when installing. Be sure to install the Subwoofer vertically.

LINE INPUT
1 SPEAKER INPUT terminals Connect to the speaker output terminals on your amplifier or receiver. 2 SPEAKER OUTPUT terminals These terminals output the signal received at the SPEAKER INPUT terminals. You can use them to relay the signla to your front speakers.
3 LINE INPUT jack This jack is used to connect the subwoofer Preout jack of the amplifier or receiver. 4 Power cord Connect to AC outlet.
You can connect the subwoofer to your amplifier or receiver in one of ways, as described below. Refer to the indicated page for connection instructions.
If your amplifier or receiver includes a Subwoofer Preout jack;
For connection instructions, see Connecting to Amps Subwoofer Preout jack 6
If your amplifier or receiver does not include a Subwoofer Preout jack;
In this case, you can connect to the speaker output terminals on your amplifier or receiver. For connection instructions, see Connecting to Amps Speaker output terminals 6
Notes: 1. Be sure to connect all cables securely. Insecure connections may result in distortion or noise. 2. Always unplug the power cord before connecting or disconnecting cables. Leaving the power plugged in while making connections may result in malfunction or damage. 3. Never short the (+) and (-) speaker wires together. 4. Do not reverse L and R or (+) and (-) sides when making connections. Reversal of sides or polarities may result in unnatural, incorrectly positioned sound. 5. Please read the operation manual that came with the devices you are connecting to, and make connections accordingly.

ON OFF MIN MAX 60Hz 200Hz ON OFF
1 Power on / standby indicator This indicator indicates operation mode when it lights in green, and the Standby mode when it lights in red. 2 POWER switch Switches the power ON and OFF. 3 VOLUME control knob Adjusts the volume level of the output of the Subwoofer. Rotating the knob clockwise increases the volume level, and rotating the knob counterclockwise decreases the volume level. 4 TURNOVER switch Set this switch (to ON or OFF) according to the output signal from the amplifier or receiver which is to be connected with the Subwoofer. ON: To help the Subwoofer manifest its performance most effectively with an ordinary subwoofer pre-out signal or line-level signal, this position cuts the other components than the low frequency component so that only the bass sound is reproduced through the Subwoofer. OFF: The subwoofer output signals from these amplifier or receiver are customized to cut other components than the required low frequency component in an optimum manner according to the current sound mode in use. When the Subwoofer is combined with one of these amplifier or receiver, the TURNOVER switch should be set to OFF: The Subwoofer does not apply electrical filtering to the input signal and reproduces it faithfully through the loudspeaker. TURNOVER function does not work when the TURNOVER switch is OFF. 5 TURNOVER control knob Ajusts the balance between the bass from the front speakers and the bass from the Subwoofer.
Example of standard adjustment according to the type of front speakers. Front speaker Small speaker Medium speaker Large speaker Turnover Frequency 120~200 Hz 80~120 Hz 60~80 Hz
Depending on the listening room condition and the front speaker characteristics, other adjustment setting than the examples shown above may provide more natual bass sound and more effective bass reproduction. Try various adjustment settings to select the optimum one for your listening room. TURNOVER function does not work when the TURNOVER switch is OFF. 6 SPEAKER OUTPUT terminals SPEAKER INPUT termnals LINE INPUT jack AUTO SHUTOFF switch Switches AUTO SHUTOFF mode ON and OFF.
