   Connect a single RCA cable from the LFE or Subwoofer output of your AV receiver/processor to the LFE IN jack on the DN12. This connection bypasses the subwoofer's internal low-pass filter, allowing your receiver to manage bass management.
2. Line In (Stereo RCA):
   For stereo systems or receivers without an LFE output, connect RCA cables from the pre-out (left and right) of your amplifier/receiver to the LINE IN (Left/Right) jacks on the DN12. In this configuration, the subwoofer's internal low-pass filter will be active.

The following controls are available on the rear panel and via the remote control:

• VOLIM: Adjusts the overall output level of the subwoofer. Start with a moderate level and adjust to blend with your main speakers.
• PASS BA: Sets the upper frequency limit for the subwoofer. This is typically set between 80Hz and 120Hz, depending on your main speakers' low-frequency extension. If using the LFE input, this control is usually bypassed by the receiver's bass management.
• FAZ: Adjusts the phase of the subwoofer output (0 to 360 degrees) to ensure it aligns acoustically with your main speakers. Experiment with settings to achieve the most coherent bass.
• EQ: Selects between three equalization modes: Flat (neutral response), Gwo twou san fon (extended low-frequency response), and Byen fò (increased output for maximum impact).
• AFICHE: Controls the brightness or turns off the front panel display.
