240 Watt Subwoofer Plate Amplifier Model: SA240/SA240-B User Manual daytonaudio.
Thank you for purchasing the SA240 Subwoofer Amplifier. It has been designed and built to provide years of high quality sound reproduction, and is ideal for use in both home stereo and home theatre systems. The amplifier has been engineered to include features like a choice of high or low level audio connections, selectable crossover frequency, auto on/off circuit activated by input signal, and comprehensive internal production against shorted speaker loads, thermal faults, and overload conditions.
INPUT/OUTPUT CONNECTIONS capability, you could set the control to a fairly low value at 40, 60, or even 100 Hz. If the main speakers are smaller or do not have much bass output, set the control higher. Experiment with the amount of “overlap” that you will experience when all speakers are playing in the same range. This can be helpful when integrating the subwoofer with the rest of the system and with the room.
NOTES ABOUT HUM: While the SA240 has been designed to minimize the possibility of hum in the subwoofer system, it is still possible that a hum will occur in rare circumstances. Its safety grounding can create a path for small amounts of 60 Hz energy to travel trough the line-level audio system. While not dangerous, this energy can cause difficulty with the subwoofer auto signal sensing circuit, and at the very least will interfere with the quiet enjoyment of your system.
