Description

The AC45.2 is an amplified speaker system featuring a subwoofer for extended low frequency response. The system is especially designed for multimedia computer near field monitoring. A patented control circuit automatically boosts bass at low volume to maintain musical sound realism. Electronic up/down controls adjust system volume. The subwoofer has a separate volume control for blending the subwoofer level with the satellites to the listeners preference. The satellite speakers have a detachable base that allows the speakers to be angled upwards if desired for better directivity of sound. The satellites are magnetically shielded to prevent distortion of monitor images. Please note, that the subwoofer is NOT magnetically shielded and should not be placed in close proximity to the monitor.

Connecting Power Cord

AC Wall Socket Long slot is neutral (ground) side. Insert the wide blade into the ground side so. lt

CAUTION

To prevent electric shock do not use this (polarized) plug with an extension cord, receptacle or other outlet unless the blades can be fully inserted to prevent blade exposure.

WARNING

TO REDUCE THE RISK OF FIRE OR ELECTRIC SHOCK, DO NOT EXPOSE THIS APPLIANCE TO RAIN OR MOISTURE.
ACS45.2 Setup Instructions
Do not put the power plug into an AC outlet before all connections are made. For easy insertion of the DIN connector, notice that the arrow must face up.

levelof the subwoofer with the satellite speakers. Mixing is usually done by playing a wide variety of music and speech and adjusting the control until a natural sound is obtained.

Placement of Speakers

All stereo information is heard from the satellite speakers. The subwoofer contains no stereo information and the sound is non-directional. As a result, the subwoofer does not necessarily have to be placed in any particular relationship to the satellites. Placing the subwoofer on the floor close to a wall or corner of a room, provides maximum bass efficiency. The subwoofer can be placed below tables, behind couches and on bookshelves, etc. The satellite speakers are magnetically shielded and can be placed close the other computer monitor without distorting the video image. Best stereo effect is obtained
by placing speakers as far apart as the cord set allows.

Troubleshooting

When first installing a new system, some simple instructions may be overlooked which can cause the unit to be inoperative. Please make the following checks: Make sure all connecting plugs between the satellite speakers, subwoofer (if applicable) and computer are fully seated. Make sure the wall power outlet or power strip has power. The outlet can be checked with a lamp or some other appliance. If the power strip has a switch, make sure it is turned on. It is possible to test the unit by pulling out the audio cable that is connected to the computer and connecting it to an alternate audio source such as a portable CD player. When the unit is operative, vibrations may lead to the erroneous conclusion that the speakers are defective. In most instances, removing the vibrating object cures the problem.

(See Figure 3)

On/Off Switch: The unit is turned on/off by pressing both the up/down volume controls simultaneously. Volume Up/Down: Volume is controlled electronically by the use of two push buttons located on the top of the right satellite. Arrows on the push button indicate volume up/down. The left
