P-1200 Controls

The P-1200 subwoofer has thee variable controls for tailoring its output to the room and to the primary speakers (also known as satellites). These controls are Level, Crossover Frequency, and Phase. The control with the most audible effect is the Level control, followed by the Crossover Frequency, and then the Phase control, which has the least audible effect.

The following legend shows graphically how each control affects the audio signal.

Fine Tuning the Controls

We recommend the following method as a starting point for fine tuning the P-1200 subwoofer.

Level and Frequency

A)Begin with the subwoofer’s Level control all the way down and the Frequency adjustment set to 120Hz. With the Frequency control in this position the woofer will output higher frequencies that will likely be duplicated by the satellite speakers.

B)Play some familiar music through the system (music with robust bass content) and increase the Level control until the bass passages sound robust or exaggerated. Then reduce the Frequency control to blend the subwoofer with your main system speakers. We have found that most speakers with 6” to 8” woofers blend well with the crossover set somewhere between 50Hz and 80Hz.

C)Readjust the Level and the Frequency controls (up or down) as necessary until the bass sounds full, extended, and natural. Use multiple musical pieces to test the system while fine tuning the controls. If it sounds like your subwoofer is always producing the same bass note with different recordings it is possible that the bass level is adjusted too high.

Phase

A)To adjust the Phase, use music with sustained bass notes.

B)Rotate the Phase control back and forth across its range and listen for the localization of the bass to become more distinct and also slightly louder. While making this adjustment it is helpful to temporarily adjust the Frequency control to 120Hz. This should provide some overlap of the satellite and subwoofer frequencies and help the ears (brain) to distinguish the two sound sources. Return the Frequency control back to its desired position after performing the phase adjustment.
