PRODUCT OVERVIEW

1. VOLUME LEVEL: Sets the output volume level.

2. LOW-PASS FILTER: Sets the crossover frequency between the subwoofer and the main speakers between 40 ~ 150 Hz.
   The subwoofer handles all frequencies below the crossover frequency.

3. POWER MODE: Determines whether the subwoofer will go into Standby mode or not. When the switch is set to the On position, the subwoofer On/Off status is determined solely by the POWER switch. When set to the Auto position, the subwoofer will automatically enter Standby mode after about 2 minutes with no input and will turn back on when audio material is detected. The POWER switch must be in the ON position for the Auto Standby function to operate.

4. PHASE: This control allows you to alter the phase of the subwoofer’s output signal to 0° or 180° to correct for a possible mismatch in phase, which results in cancellation between the subwoofer and your main speakers. To adjust the PHASE, listen to the system with music playing and switch between 0° and 180° while listening for a change in mid-bass output. The correct position will have a higher amount of apparent mid-bass output.

5. SPEAKER LEVEL IN: If your amplifier lacks both a dedicated subwoofer output or preamplifier outputs, connect the stereo speaker outputs on your amplifier to the SPEAKER LEVEL IN inputs using 2 speaker wires (not included).

6. LINE IN/SUB IN: If your amplifier has a dedicated subwoofer output (usually labeled SUB or LFE), use a mono RCA cable (not included) to connect the SUB/LFE output on your amp to the left (L) input on the subwoofer. Alternatively, you can use an RCA splitter cable (not included) to connect it to both the L and R inputs. If your amp does not have a dedicated subwoofer output but does have a preamplifier output, use a stereo RCA cable (not included) to connect the stereo preamplifier output to the L and R inputs.

7. POWER: Use the switch to turn the subwoofer ON or OFF. If you are using the Auto Standby feature, the switch should be left in the ON position.

8. 120V ~ 60Hz: Plug the power cord into a nearby AC power outlet. The subwoofer requires a nominal 120 VAC, 60Hz power source.

CONNECTING TO YOUR SYSTEM

Connecting to a SUB/LFE Output
The best connection to the subwoofer is using a dedicated subwoofer output, if your amplifier has one, using a single, mono RCA cable (not included). Perform the following steps to connect the subwoofer to a dedicated SUB/LFE output on your receiver or amplifier. Note that any receiver that can decode Dolby Digital™ or DTS® soundtracks will have a dedicated SUB/LFE output.

1. Power off and unplug all equipment to be connected.
2. Using a single, mono RCA cable (not included), plug one end into the LINE IN/SUB IN L input on the subwoofer, then plug the other end into the dedicated SUB/LFE output on your amplifier.
3. Turn the VOLUME LEVEL and LOW-PASS FILTER knobs fully counter clockwise to the minimum position.
4. Ensure that the POWER switch on the subwoofer is in the OFF position.
5. Plug the Power Cord into a nearby AC power outlet. The subwoofer requires a nominal 120 VAC, 60Hz power source.
6. Plug in and power on all connected equipment.
7. Set the POWER switch on the subwoofer to the ON position.
8. Start playing audio material with significant low frequency content. Adjust the main system volume control until it is at a comfortable listening level.
9. Slowly turn the VOLUME LEVEL knob clockwise until the bass content from the subwoofer is at about the same volume level as the audio from your main speakers.
10. Slowly rotate the LOW-PASS FILTER knob clockwise until the low frequency content from the subwoofer blends smoothly with the audio from the main speakers in the crossover region. If the crossover frequency is set too high, the bass will sound “boomy” and male voices will have an unnatural “chesty” quality.

Connecting to a Stereo Preamplifier Output

The next best type of connection is to connect to the stereo preamplifier output on an amplifier or receiver using a stereo RCA cable (not included). Perform the following steps to connect the subwoofer to a stereo preamplifier output.

1. Power off and unplug all equipment to be connected.

2. Using a stereo RCA cable (not included), plug the connectors on one end into both LINE IN/SUB IN L and R inputs on the subwoofer, then plug the other end into the stereo preamplifier outputs on your amplifier. Because the subwoofer is monophonic, there is no need to match left and right channels.
   Note: If you are using an external power amplifier and your preamplifier has only a single preamp output, use RCA Y-cables (not included) on each output to allow both the power amplifier and the subwoofer to be connected to each output.

3. Turn the VOLUME LEVEL and LOW-PASS FILTER knobs fully counter clockwise to the minimum position.

4. Ensure that the POWER switch on the subwoofer is in the OFF position.

5. Plug the Power Cord into a nearby AC power outlet. The subwoofer requires a nominal 120 VAC, 60Hz power source.

6. Plug in and power on all connected equipment.

7. Set the POWER switch on the subwoofer to the ON position.

8. Start playing audio material with significant low frequency content. Adjust the main system volume control until it is at a comfortable listening level.

9. Slowly turn the VOLUME LEVEL knob clockwise until the bass content from the subwoofer is at about the same volume level as the audio from your main speakers.

10. Slowly rotate the LOW-PASS FILTER knob clockwise until the low-frequency content from the subwoofer blends smoothly with the audio from the main speakers in the crossover region. If the crossover frequency is set too high, the bass will sound “boomy” and male voices will have an unnatural “chesty” quality.

Connecting to Speaker Level Outputs

The least desirable connection is to connect to the stereo speaker outputs on your amplifier using a pair of speaker wires (not included). Perform the following steps to connect the subwoofer to speaker level outputs on your amplifier.

1. Power off and unplug all equipment to be connected.
2. Using a speaker wire (not included), plug one end into the SPEAKER LEVEL IN L input, then plug the other end into the left channel speaker level output on your amplifier. If your amplifier has more than 2 speaker outputs, use the main or front speaker outputs. Take care to ensure that polarity is properly maintained. Repeat using a second speaker wire (not included) for the R channel.
3. Turn the VOLUME LEVEL and LOW-PASS FILTER knobs fully counterclockwise to the minimum position.
4. Ensure that the POWER switch on the subwoofer is in the OFF position.
5. Plug the Power Cord into a nearby AC power outlet. The subwoofer requires a nominal 120 VAC, 60Hz power source.
6. Plug in and power on all connected equipment.
7. Set the POWER switch on the subwoofer to the ON position.
8. Start playing audio material with significant low-frequency content. Adjust the main system volume control until it is at a comfortable listening level.
9. Slowly turn the VOLUME LEVEL knob clockwise until the bass content from the subwoofer is at about the same volume level as the audio from your main speakers.
10. Slowly rotate the LOW-PASS FILTER knob clockwise until the low-frequency content from the subwoofer blends smoothly with the audio from the main speakers in the crossover region. If the crossover frequency is set too high, the bass will sound “boomy” and male voices will have an unnatural “chesty” quality.

SUBWOOFER POSITIONING

In most rooms, the optimum location for your subwoofer is in the closest solid front corner or somewhere along the front wall in line with your front speakers. This location typically offers optimal energy coupling with the room, front speakers, and the deepest low frequency extension, with the best high impact bass. Try to avoid a location that is far away from walls or near the center of your room.

Bass output is maximized when the subwoofer is tucked into a corner. An ideal corner is far from wall divisions and has at least 6 feet or more of wall to either side. Try to keep the subwoofer placement away from any large openings into other rooms. When corner loading a subwoofer, you might want to experiment with how close the subwoofer sits to the closest wall, with a general rule of thumb that it should be within 1 foot.

Placing the subwoofer in close proximity to the seating position, for example, right next to or behind the sofa, maximizes the output and can reduce room effects on the subwoofer.
A great technique for determining the best placement for your subwoofer is known as the Subwoofer Crawl. The first step is to place the subwoofer at your listening position. Ensure that audio with constant bass content or a test tone is playing. Next, crawl around the room (after all, the subwoofer will not be 5 feet in the air) and listen for where the bass sounds most full and has definition, punch, and depth. This will generally be the best location in your room.
