RF Breakthrough Advisory If this product is placed too close to a high level source of RF energy, RF breakthrough may be experienced which can cause some audio disturbance. If this happens, move the product as far away as possible from the source until the disturbance is eliminated. Using an audio input cable with a high percentage of shielding is also helpful in reducing or eliminating interference.
Introduction The ADA880 is a technologically advanced multimedia amplified speaker system featuring Dolby Digital AC3 and Dolby Pro-Logic surround sound and stereo reproduction. The amplifier inputs can simultaneously operate on analog and digital (S/PDIF)* audio signals. The unit is comprised of a subwoofer and two satellite speakers. This combination provides surround sound on a desktop by utilizing side firing speakers.
Setup Do not plug the AC power plug into the wall outlet until all connections are made. The ADA880 can be setup in two configurations. For ENHANCED SURROUND sound a 5-piece setup is used. For near field STEREO/SURROUND sound a 3-piece setup is used. The two modes of operation are described below. The speakers are packaged and shipped in the 5-piece arrangement. Follow the instructions and pictorial view below to make the 5-piece connections.
Figure 3 Placement of Speakers (See Figures 4 and 5) All stereo information is heard from the satellite and surround speakers. The subwoofer contains no stereo information and its 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.
