User manual JBL SUB 150P QUICK START GUIDE

[. . . ] Turn the knob clockwise to increase the volume; turn the knob counterclockwise to decrease the volume. Crossover Control: This control determines the highest frequency at which the subwoofer reproduces sounds. [. . . ] This effect can vary depending on the listening position ­ some listening positions may yield very good results while others may have far too much (or too little) bass at certain frequencies. In many rooms, placing the subwoofer along the same plane as the left and right speakers (2) can produce the best integration between the sound of the subwoofer and that of the left and right speakers. In some rooms, the best performance could even result from placing the subwoofer behind the listening position (3). We strongly recommend that you experiment with placement before choosing a final location for your subwoofer. One way you can determine the best location for the subwoofer is by temporarily placing it in the listening position and playing music with strong bass content. Move around to various locations in the room while the system is playing (putting your ears where the subwoofer would be placed), and listen until you find the location where the bass performance is best.

The subwoofer will automatically turn itself on when it receives an audio signal, and it will go into Standby mode after it has received no audio signal for approximately 10 minutes. The subwoofer's LED will glow green when the subwoofer is on and will glow red when the subwoofer is in Standby. If you will not be using the subwoofer for an extended period ­ for instance, if you're going on vacation ­ set the Power Switch to the "Off" position. SubwOOFER aDJuStMEntS: CROSSOVER COntROL NOTE: The Crossover control functions only when the Input Mode switch is in the "Normal" position. The Crossover control adjusts the subwoofer's built-in low-pass filter crossover between 50Hz and 200Hz. [. . . ] Although in most cases you should leave the Phase switch in the "Normal" position, there is no absolutely correct setting for the Phase switch. When the subwoofer is properly in phase with the satellite speakers, the sound will be clearer and have maximum impact, and percussive sounds like drums, piano and plucked strings will sound more lifelike.
