[. . . ] LFM Series Low Frequency Modules LFM-1 and LFM-2 ® Owner's Manual Owner's Manual Please Read First Please Read First Do Not Open The Cabinet There are no user serviceable components inside this product. Opening the cabinet may present a shock hazard, and any modification to the product will void your guarantee. If water or any metal object, such as a paper clip, coin or a staple, accidentally falls inside the unit, disconnect it from the AC power source immediately, and contact Outlaw Audio for further instructions. FCC Information for User CAUTION: ANY changes or modifications not expressly approved by the party responsible for compliance could void the user's authority to operate the equipment. [. . . ] See Diagram 2 on page 6. To connect an LFM Series Subwoofer using high level inputs: 1. Turn off all system components and unplug the receiver and/or amplifier and the LFM from their AC power source. Locate the front left/right speaker output terminals on your receiver or amplifier. In cases where there are both "A" and "B" terminals, the "A" terminals should be used. Disconnect any wire that is presently connected to these terminals. 3. Using the same type of speaker wire used for your other speaker connections, connect the left and right channel speaker outputs of your receiver or amplifier to the LFM's High Level Inputs. Be sure to connect the speaker wires to the appropriate input binding posts located on the back of the LFM, making certain that the polarity (­/+) on the receiver or amplifier matches the polarity on the binding posts of the subwoofer amplifier. In most cases this means connecting the red terminal on the receiver or amplifier to the red terminal on the LFM, but always check the markings on the rear panel to insure "+ to +" and "­ to ­" connections. Also, make sure that the negative outputs on your main amp are true ground; otherwise you would short the output of your main amp. Call or email tech support if the negative outputs on your main amplifier do not have true ground. 4. Connect the speaker wires to the high-level output terminals on the back of the LFM Series Subwoofer. Notes On Subwoofer Placement Try to avoid creating a listening position that falls directly between the front and back walls as this may cause a strong interference effect due to the collision between bass waves bouncing off the rear wall and new bass waves from the LFM. When this happens you might hear an unnatural "build up" in the low frequencies where the bass sounds "bloated", based on the specific dimensions of the room and the particular frequency being reproduced. In other situations you might encounter a "null", which is caused by two low frequency waves canceling each other out. When this happens you will find that your favorite listening position is bass shy. In this type of placement situation bass response will suffer greatly regardless of how powerful the subwoofer is. The best way to solve this problem is to change the location of the seating position so that the distance to the front of the room is different than that to the back of the room. Again, make certain that the polarity (­/+) on the receiver or amplifier matches the polarity on the binding posts of the speakers. Also, be sure to prevent any positive and negative strands of speaker wire from crossing. 5. Plug the LFM's power cord into the input on the LFM Series Subwoofer and connect the plug to an un-switched AC outlet. CAUTION: Due to the power requirements of the LFM Series Subwoofers, they must not be connected to the accessory outlets on a receiver or processor. If a power-strip or surge protector is used, make certain that it is rated to accommodate the LFM's power requirements. Reconnect your receiver and/or amplifier to the AC power source. Proceed to the "Setting The LFM's Controls" section to learn about the LFM's controls and how they operate. LFM Series Low Frequency Modules 7 Owner's Manual Setting the LFM's Controls Setting the LFM's Controls Variable Crossover By adjusting the variable crossover on the LFM, you can perfectly match your LFM Series Subwoofer to your main speakers. If your receiver or processor already has a built in crossover, disable the crossover on the LFM by flipping the "X-OVER" switch to the "BYPASS" position. Refer to the owner's manual for your receiver or processor to see how to disable any internal crossover capability it may have.
