5. Setup

5.1 Placement

The placement of your subwoofer can significantly impact its performance. Experiment with different locations to find the best bass response in your listening environment. Generally, placing the subwoofer in a corner can enhance bass output, but may also lead to boomy sound. Placing it along a wall often provides a more balanced sound. Avoid placing it directly against a wall if possible, to allow for some air circulation.

5.2 Connections

Ensure all audio equipment is turned off before making any connections.

Line Level Input (RCA)

If your AV receiver or pre-amplifier has a dedicated subwoofer output (LFE or Sub Out), connect a single RCA cable from this output to the LEFT (MONO) Line Level Input on the subwoofer. If your receiver has stereo pre-outs, connect both Left and Right RCA cables from the pre-outs to the corresponding LEFT and RIGHT Line Level Inputs on the subwoofer.

Speaker Level Input

If your amplifier or receiver does not have a dedicated subwoofer output or pre-outs, you can connect the subwoofer using the speaker level inputs. Connect the speaker cables from your amplifier's main speaker outputs to the SPEAKER LEVEL INPUTS on the subwoofer. Then, connect your main speakers from the SPEAKER LEVEL OUTPUTS on the subwoofer. Ensure correct polarity (+ to + and - to -).

5.3 Power Connection

1. Ensure the subwoofer's power switch is in the OFF position.
2. Connect the supplied AC power cord to the AC INPUT socket on the rear panel of the subwoofer.
3. Plug the other end of the power cord into a suitable wall outlet.

6. Operating Instructions

6.1 Initial Power-Up

1. After making all connections, switch the main power switch on the rear panel to ON.
2. Set the AUTO POWER ON/OFF switch to your desired setting. In "Auto" mode, the subwoofer will power on when an audio signal is detected and enter standby after a period of inactivity. In "On" mode, it will remain powered on.
3. The LED indicator on the front panel will illuminate (typically green for active, red for standby).

6.2 Controls

• Volume: Adjusts the overall output level of the subwoofer. Start with a low setting and gradually increase until the bass blends seamlessly with your main speakers.
• Crossover Frequency: This control determines the upper frequency limit at which the subwoofer operates. Set it to match the low-frequency capabilities of your main speakers. A common starting point is 80Hz-100Hz for bookshelf speakers, or lower for larger floorstanding speakers.
• Phase (0/180 degrees): This switch helps to ensure the subwoofer's output is in phase with your main speakers. Listen to music with strong bass and toggle the switch. Choose the position that provides the most impactful and coherent bass response.
• Auto Power On/Off: Selects whether the subwoofer automatically turns on/off based on audio signal detection or remains continuously on.

7. Maintenance

• Cleaning: Disconnect the power cord before cleaning. Use a soft, dry cloth to wipe the cabinet. Do not use liquid cleaners or aerosol sprays.
• Ventilation: Periodically check that the ventilation openings are clear of dust and debris.
• Storage: If storing the subwoofer for an extended period, ensure it is in a cool, dry place, protected from dust and extreme temperatures.
