CONNECTION No signal connection cable is provided with the MODEL 500 amplifier since the length of cable is installation specific. A shielded RCA type coaxial cable or a shielded two-conductor wire with RCA type connectors is required for connection of the MODEL 500 to the audio system. Before making any connections, ensure that power cord is disconnected or that the main power switch is switched to the off position.

SETUP Tips, Hints, & Suggestions The MODEL 500 controls will allow you to make the best of virtually any installation. If you feel uncomfortable with setting up your MODEL 500 after reading through this manual then you should consider enlisting the help of an experienced person or contacting your dealer. Below are a few generalized rules for understanding the acoustic nature of low frequency sound reproduction in an average residential listening room.
S E T U P (continued) MODEL 500 Controls The MODEL 500 subwoofer amplifier has four variable controls to integrate its output to the subwoofer and for tailoring the subwoofer’s output to the room and to the primary speakers (also known as satellites). These controls are Level, Crossover Frequency, Phase, and subsonic filter. The control with the most audible effect is the Level control, followed by the Crossover Frequency, Phase control, and then Subsonic filter, which has the least audible effect.
S E T U P (continued) Other Controls A) Crossover Switch If you choose to bypass the internal crossover and use an external crossover, such as those located in most modern receivers and processors, then you will need to fine tune the system based on the adjustments provided by the manufacturer of your electronics in conjunction with the Level and Phase controls on the MODEL 500. Note, the Level and Phase adjustments on the MODEL 500 are not bypassed and will still function as indicated above.
