Phase Control | American Acoustic Development M Series instruction

3Crossover frequency control

If you are using small loudspeakers (4" to 6" woofers) in your main system, your will need to set the crossover frequency at a high position(100 to 160Hz). If your main speakers have larger woofers(8" and above) you will need to set the crossover frequency to much lower position (40 to 80 Hz). Generally, the larger the speaker, the greater the low frequency output will be. If the frequency control is set too high, the bass will appear "boomy" due to outputs of subwoofer and main speakers overlapping each other. If it is set too low, the bass will be ill defined and the subwoofer will sound detached from the rest of the system.

4Phase Control

Use this control to determine the best possible bass performance of your system. There can be interference between your main speakers and subwoofer at the frequency where they cross over due to placement, room acoustics and type of main speaker used. By carefully positioning the subwoofer in the room in combination with the level and crossover control, you should be able to get a seamless transition between your main speakers and subwoofer. Start with the full anticlockwise 0 degree position. This means that the subwoofer will push out positive pressure wave corresponding to a positive electrical input. The 180 degree full clockwise position inverts this so the subwoofer will put out a negative pressure wave. You can use this position if you are unable to get a good integration between the subwoofer and main speaker.

Power input socket and Fuse

For continued protection, replace only with same type fuse.

Line In/ Line Out

Connect Line in to the subwoofer output of your amplifier/receiver. If you do not have a subwoofer output, you can connect up the subwoofer using the Line In/Out utilizing a tape input/output amplifier/receiver. Connect the tape output to the Line Input on the subwoofer, then connect the tape input to the Line Output on the subwoofer. To switch the subwoofer into the circuit, switch the tape monitor input on your amplifier/receiver.
