Sony SA-WX700 - Subwoofer Manual

Installation

Since the human ear cannot detect the direction and position where the bass sound being reproduced by a woofer (below 200 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.

Connecting to an amplifier with a single set of speaker terminals
Connect the woofer to the amplifier, and then connect the front speakers to the woofer using the supplied speaker cords (1 for each speaker). (B)

Twist the stripped ends of the cord about 15 mm ( ⁵/₈ in.).
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.

1. Connect the woofer to the amplifier. (C)
   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.
   
2. Connect the front speakers to the woofer. (D)
   Connect the speakers to the speaker terminals of the woofer.
   

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 using the supplied speaker cords (1 for each speaker). (B)
Twist the stripped ends of the cord about 15 mm ( ⁵/₈ in.).

1. Connect the front speakers to the amplifier. (E)
   
   Connect the speakers to your amplifier's speaker terminals (A).
2. Connect the woofer to the amplifier. (F)
   
   Connect the SPEAKER IN terminals of the woofer to the amplifier's speaker terminals (B) using speaker cords (supplied).

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.
