Trl U2 Position the speakers at least 12 inches (30 cm) away from side walls. For stronger bass response The most accurate bass response results when the speakers are Set less than 18 inches (45 cm) away from the wall behind them, and more than 18 inches from the floor or ceiling. Avoid placing the speakers exactly halfway between the floor and ceiling. If your music system seems to lack deep bass, try moving the speakers closer to the wall behind them and/or nearer to the corners of the room. Heavy, 'booming' bass can be softened by moving the speakers away from corners and walls. You can also experiment with the tone controls on your amplifier or receiver to achieve a tonal balance that suits your listening environment and personal tastes. For use with video The 4.2 speakers are suitable for video sound applications. Place one speaker on either side of your TV screen, at least 24 inches from the screen to avoid picture interference. Connecting your speaker wires Use of the proper gauge (thickness) of speaker wire is important. Standard zip cord (2-conductor. 18-gauge wire found at electrical and hardware stores) can be used in most applications. If your speakers will be positioned more than 30 feet from the receiver or amplifier, check with your Bose' dealer or refer to the Wire recommendations under "Technical information." To make the proper connections Refer to figure 2. Turn off your amplifier or receiver and unplug it from the AC (mains) power outlet before connecting any wires. Caution: if the amplifier or receiver is not turned off, damage to your system may occur. Preparation At the ends or each cord, strip approximately 1/2 inch (12 mm) of insulation from each wire. Twist the stripped wire ends. Note that one wire is plain and the other is marked (striped, ribbed or collared). Connection #1 Select one cord and connect it to the left channel of your amplifier. • Attach one stripped end of the marked wire to the red (+) terminal. • Attach the stripped end of the plain wire to the black (-) terminal. 2
