Getting Started

Unpacking

Check that you received the following items:

• Audio connecting cord (1)

• Speaker cords (2)

Installation

Since the human ear cannot detect the direction and position where the bass sound being reproduced by a woofer (below 120 Hz) comes from, you can install the woofer wherever you like in your room. To obtain a better bass reproduction, we recommend you to install the woofer on a solid floor where the resonance is unlikely to occur. You can obtain a sufficient heavy bass reproduction from a single woofer. However if you use a couple of the woofers, you can obtain an even more effective heavy bass reproduction.

Notes

• Always install the woofer vertically, keeping a few centimeters from away the wall.

• Do not place an object on the woofer or sit on it.

• If the woofer is installed 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 woofer away from the center of a room or eliminate the cause of the standing wave, by installing a bookshelf on the wall, etc.

Hooking Up the System

Overview

Use the LINE IN jacks or the SPEAKER IN terminals of the woofer when you connect the amplifier.

• If your amplifier has one of the following types of output jacks, connect the LINE IN jack and the amplifier’s jack using the supplied audio connecting cord.

— MONO OUT jack — MIX OUT jack — SUBWOOFER output jack(s) — SUPER WOOFER output jack(s)

• If your amplifier does not have the above mentioned

output jacks, connect the speaker terminals of the amplifier to the SPEAKER IN terminals instead.

Before you get started

• Turn off the power of the amplifier and the woofer before making any connection.

• Use the audio connecting cords that are supplied to the respective equipment. If there are not enough audio connecting cords to make the necessary connections, you need to purchase some optional audio connecting cords.

• Be sure to make connections firmly to avoid noise.

• Connect the AC power cord from the woofer to a

wall outlet.

• You cannot connect the CENTER output jack for use with Dolby Pro Logic function to the woofer. Bass sound is not output with some Dolby Pro Logic modes.

(continued)

Getting Started

Connecting to an amplifier with a single set of speaker terminals

If your amplifier is equipped with a single set of speaker terminals, connect the woofer to the amplifier, and then connect the front speakers to the woofer.

What cords will I need?

Speaker cord (supplied) (1 for each speaker)

Twist the stripped ends of the cord about 15 mm. Be sure to match the speaker cord to the appropriate terminal on the components: + to + and – to –. If the cords are reversed, the sound will be distorted and will lack bass. It is useful to decide that the speaker cord marked with a line is always the negative (–) and should be connected to the negative (–) terminal to avoid any improper connections.

Hookups

1 Connect the woofer to the amplifier.

Connect the SPEAKER IN terminals of the woofer to the amplifier’s speaker terminals with the speaker cords. Be sure to connect both L and R channels.

Connecting to an amplifier with double (A + B) sets of speaker terminals

If your amplifier has double (A + B) sets of speaker terminals, connect both the woofer and the front speakers to the amplifier.

What cords will I need?

Speaker cord (supplied) (1 for each speaker)

Twist the stripped ends of the cord about 15 mm.

Hookups

1 Connect the front speakers to the amplifier.

When using the double (A + B) sets of speakers, make sure that you select the “A + B” position with your amplifier.

Note

When you are using speaker terminal (A) only (front speaker only) or when the power of the amplifier is turned off, turn down the volume or turn off the power of the woofer otherwise, hum noise may be heard.

Getting Started

Connecting to an amplifier with a special jack for a subwoofer

If your amplifier has a special jack for a subwoofer (like a MONO OUT jack, MIX OUT jack, SUBWOOFER jack or SUPER WOOFER jack), connect the LINE IN jack of the woofer to one of those jacks.

What cords will I need?

Audio connecting cord (supplied) (1)

Hookups

Connect the MONO OUT jack of your amplifier to the LINE IN jack of the woofer with the supplied audio connecting cord.

Note

If the output level of your amplifier is not large enough, the sound may not be loud enough. In this case, connect the speaker terminals of the amplifier directly to the SPEAKER IN terminals of the woofer.

Connecting the AC power cord

• Connect the AC power cord from the woofer and

from your amplifier to a wall outlet.

• Make sure that power to the woofer is turned off

before you plug in or unplug any power cord.

Basic Operations

Listening to the Sound

POWER POWER indicator

Turn on the amplifier and select the program source.

Note

Never set the amplifier’s tone control (BASS, TREBLE, etc.) or the equalizer output to a high level or input sine curves of 20 Hz to 50 Hz recorded on a commerciallyavailable test disc or special sound (bass sound of electronic musical instrument, pop noise of analog disc turntable, sound with abnormally enhanced bass, etc.) in a high level to this unit. These actions may cause damage to the speakers. When a special disc containing abnormally enhanced bass is played, noise may be output in addition to the original sound. In such a case, decrease the sound level.

Note

The subwoofer output signal (DOLBY digital (AC-3) signal) of the digital surround processor sold singularly is set 10 dB higher by Dolby laboratories Licensing Corporation. In the case of using normally, adjust the subwoofer level.

Note

If you turn down the volume level of the woofer too low, the auto power on/off function may activate, causing the woofer to enter power saving mode.

Press POWER.

The woofer turns on and the POWER indicator lights up in green.

Play the program source.

Adjust the VOLUME so that sound from the front speakers is not distorted. If it is distorted, the sound from the woofer will also be distorted.

To turn on and off the power automatically — Auto power on/off

function

When the woofer is on (i.e, the POWER indicator lights up green) and there is no signal input for about seven minutes, the POWER indicator changes to red and the woofer enters power saving mode. While in this mode a signal is input to the woofer, the woofer automatically turns on (auto power on/off function). To turn this feature off, slide the POWER SAVE switch on the rear panel to OFF.
