The RM7600 Powered Subwoofer offers a wide range of setting options. We recommend the following settings as starting points, but the settings that are best for you depend upon your speaker placement, electronics and personal taste. After you’ve become familiar with what the settings do, experiment with alternate options to find the method that works best for your system setup.

Outside the US:

These adjustments are specific to the Polk Audio PSW650 Model Subwoofer. If you are using a subwoofer other than the PSW650, please refer to that subwoofer’s owner’s manual for correct, model-specific adjustment instructions

You’ll find an informative article on “Subwoofer Positioning and Adjustment” in the set up section at http://www.polkaudio.com/home/faqad/.

The RM7600 Powered Subwoofer has a built-in power amplifier and must be plugged into a standard household AC power source in order to operate. The power switch has three positions: “On,” “Off” and “Auto” (Figure 14). The Powered Subwoofer also has a small GREEN light under the Level Control Pod on the subwoofer’s front face. This light is not illuminated when the Subwoofer power switch is in the “Off” position. In the “Auto” position, the amplifier will automatically turn on as soon as the speaker senses a signal coming from your electronics. The power light will glow GREEN upon sensing a signal. The subwoofer will turn off approximately 15 minutes after input signal ceases, and the power light will go off. In the “On” position, the power amplifier will operate and the power light will glow GREEN until the switch is set to the “Off” position or the AC cord is disconnected from a power source. We recommend using the “Auto” position. Turn it to “Off” if the system will not be used for extended periods of time, such as during vacations.

Subwoofer level (volume) is adjusted via the knob on the front of the subwoofer under the logo pod. This lets you adjust the level of bass easily after you have made the more complex adjustments on the rear of the Subwoofer. To set level, play a piece of music that has an average amount of bass content. Start with the knob set to “5” and the Phase Switch set to 0. Adjust by ear using a wide variety of CDs and video sources. Adjust for deep, powerful bass without “boominess.”

On the back of the subwoofer (Figure 14), you will see the following controls:

ƒVariable crossover control

ƒPhase toggle switch

ƒ+3dB bass boost switch

ƒHigh Pass Filter toggle switch (You will never need to change this out of the “0” position. Trust us.)

The Subwoofer Level Control is found under the logo pod on the front of the subwoofer.

This control adjusts the frequency range over which the subwoofer operates. It only effects signals that are sent through the low level, subwoofer and Speaker Wire inputs. It has no effect on signals fed into the LFE input (and you shouldn’t be using that input anyway).

Mounting your right and left front satellites on the wall tends to increase their low-midrange response (the low range of a male voice). Mounting them on stands away from the sides of the room tends to decrease their low-midrange response. If you mount the satellites on the wall, we recommend setting your variable crossover control (see Figure 14) at a lower setting (Figure 15a). If you mount the satellites on stands, we recommend setting your variable crossover control at a higher setting (Figure 15b).

Turning the knob up from the recommended setting (Figure 15a or 15b) will add more “warmth” to the bass and lower midrange, possibly at the sacrifice of bass “tightness” and midrange clarity. Turning the knob down from the recommended setting will make the bass and lower midrange sound “thinner.”

Changing the phase of your subwoofer can strengthen its bass “attack.” If the bass sounds muddy or unclear, try toggling the phase control. Have someone else switch between the two settings while you sit in your favorite listening position. Use music with good bass (preferably “plucked” string bass) and a deep male vocal. When you hear the best balance of deep bass and natural lower octaves of the male voice, you have achieved optimum phase tuning.
