AC POWER

This LSi powered loudspeaker has a built-in power amplifier and must be plugged into a standard household AC power source in order to operate properly.

The power switch on the rear amp plate [figure 8] has three positions, “Off,” “On” and

“Auto,”and a small LED light. The LED will glow green at all times that the powered loudspeaker is plugged in (even if the speaker is set to “Off”). We meant it that way.

In the “Auto” position, the amplifier will automatically turn on as soon as the speaker senses a signal coming from your pre-amp, integrated amp or receiver. It will automatically turn off several minutes after signals cease to be sent by your pre-amp, integrated amp or receiver. The LED will glow green at all times.

In the “On” position, the power amplifier will operate until the switch is set to “Off,” or until the AC cord is disconnected from a power source. The LED will glow green at all times.

SUBWOOFER VOLUME CONTROL

Subwoofer level is adjusted via the VOLUME knob located on the amp plate [figure 8]. Adjust the volume by ear using a wide variety of CD or video sources. Adjust for deep powerful bass without “boominess.”

FREQUENCY ADJUSTMENT

The FREQUENCY knob adjusts the frequency range over which the subwoofer operates. This control [figure 8] only affects signals that are sent through the “LINE LEVEL IN” jack and the “SPEAKER LEVEL INPUT.” It has no effect on signals fed into the “LFE IN” jack. After setting subwoofer level, you may want to experiment with this frequency setting. Turning the knob clockwise from the “FACTORY SETTING” will add more “warmth” to the bass and lower mid-range, possibly at the expense of bass “tightness.” Turning the knob “down” from the recommended setting will make the bass and lower mid-range sound “thinner.”

TAKING CARE OF YOUR

LSi SERIES FLOORSTANDING LOUDSPEAKERS

The side panels of your new LSi Loudspeakers are finished in natural wood veneer. Clean these panels periodically with a soft cloth and furniture polish to remove dust and fingerprints. Avoid harsh detergents and cleaning fluids [figure 9]. Clean and dust the Gloss Black lacquer area with a damp cloth only. Do not use furniture polish on the Gloss Black lacquer. Carefully vacuum the grilles to remove dust.
